Nice☺️👍

Kanskje vi kan prøve å identifisere hvilken telefon sin bakside denne tilhører?

https://paste.pics/CV8OJ

Eller kanskje den telefonen ikke har noe med tlens å gjøre (bare en dummy)?
Eller kanskje prototypen avviker totalt slik at det ikke er mulig?

Det er en Google pixel 3 XL, der de nok bare har erstattet den originale kameramodulen med TLens, i tillegg til sin egen kameraapp, som proof of concept

aha! 👍

Dette var spennende.

Visionox og polight samarbeider.

Står det noe om Visionox sammarbeid her?

Bare for å ha det på det rene:

Tlens fra Polight kommer garantert i en smartphone ( fra en Tier 1) i år?? Eller er det noe vi ikke kan være sikre på nå??

Design in, ble sagt på Q1. Design win, er noe vi alle venter på nå.

Når en produsent, altså en OEM, jobber med ulike løsninger for f.eks kamera, mikrofon eller skjerm på en telefon, så testes eller velges det gjerne blant mange løsninger. Når OEM har bestemt seg for hva de skal bruke så låses designet. Da er avgjørelsen om teknologisk valg tatt, og dette kalles "Design In".

TLens fra poLight er valgt i en bestemt modell fra en av de største produsentene, altså OEM har låst designet på denne enheten MED TLens. Det er en svært stor avgjørelse for begge parter, og poLight er bedt om å være klare til å levere linser til denne modellen senest til Q4 2021, altså de skal være klare til levering SENEST om 3 måneder. I min verden betyr "senest" gjerne at det kan skje før, men det blir bare spekulasjon fra min side.

Vi vet også at poLight har produsert og rampet opp produksjonen i en viss tid, ansatt flere folk, ordret testutstyr og sier de vil holde begge monteringspartnerne opptatte fremover.

Men; det er ikke en "done deal" før kontrakten kommer. Jeg har selv vært i kontakt med selskapet og etterspurt hvor lang tid i forveien en slik kontrakt må komme. Det kan de selvfølgelig ikke svare på, men opplyser at generelt i dette segmentet vil en kunde måtte levere inn en PO (purchase order) en viss tid før leveransen finner sted, og volumet vil være for de flrste måneder. Dette betyr at vi får melding om dette før levering, og før smartphone lanseres, og det vil gjerne komme flere ordre underveis. Når PO kommer så sikres poLights inntekt. Det er en bindende avtale med bestilling av et antall linser og en bestemt leveransetid.

Telefonen vet vi ikke når den kommer for salg, men det er ikke så viktig heller. Det er leveransen som er viktig!

Dersom TLens ikke skal komme i smarttelefonen de er designet inn i så skal det skje dramatiske ting. OEM slutter med telefoner, avlyser hele modellen, osv.

Som et lite apropos; TLens er også låst i design i AR-briller i både industrial- og i consumermarkedet. En av disse kommer på markedet allerede i 2021 eller tidlig 2022. Denne kan vi også begynne å vente på nyheter om😉

Utdrag:



Technical field

This application relates to the field of camera technology, and more specifically, to a calibration method of defocus conversion coefficient, a PDAF method, and a camera module.

Background technique

Phase detection auto focus (PDAF) is to regularly insert some pairs of shielded pixels (shield pixels) in the image sensor to sense the phase difference of the image of the subject when the motor is at the current position. The principle is to calculate the direction and distance of movement of the motor when a clear image is obtained according to the phase difference information and the defocus conversion coefficient, and then the motor pushes the lens to the corresponding position to complete focusing at one time.

Therefore, in order to meet the needs of users for functions such as reduced thickness of terminal equipment, fast AF focusing, fast optical image stabilization (OIS), continuous optical zoom, ultra-macro shooting, etc., the camera module needs to be designed with a new model Lens, such as liquid lens, liquid crystal lens, adjustable lens (Tlens) and other variable-focus lenses or deformable mirrors, prisms, and/or use some non-linear motor systems. These new structural designs and new lens materials will cause the drive current and the image distance of the optical system to be nonlinear, the drive current and the focal length of the optical system are nonlinear, and the phase difference between the drive current and the imaging system is nonlinear, or drive The current and the motor stroke are non-linear and so on.

Meget spennende.

☺️👍

Nice, Kraamz!
Dette viser oss at Huawei er aktive med poLights tech. Huawei er det selskapet som det har florert desidert mest rykter og diskusjoner i lang tid om bruk av "liquid lenses". De hentet da også over Ofilms ansvarlige for testing av TLens til sitt selskap i 2020. Ikke sikkert det er samme person som har ansvaret for testing og prøving av TLens i Huawei nå, men det er uansett spennende å se at noen av de som kjenner TLens går til OEM-selskapene!

Dette patentet du fant her er svært lovende! Det er mye av forklaringer og beskrivelser av behov her som kan peke på at TLens er det beste valget for Huawei. Blir spennende å følge med fremover!

Ser lovende ut☺️☺️ No må bare smal nosen sette en flott referanse og bane veien videre🤞😃

Så der fikk Xiaomi klokken lengre levetid? ☺️

Ny add-in cameramodule-supplier!
Isaksen fortalte oss på Q1 at prosjektet var meget godt mottatt, og flere smartphone- og cameramodul-vendors var allerede i gang med egne prosjekter på samme prinsipp.

Denne CM-supplier har patentett et add-in TLens-kamera for bruk i både smartphones, pc og wrarables (som klokker etc.).

I tillegg til at det rr mange tekniske fordeler med denne, er det ifølge oppfinneren en modul med lav kostnad. Akkurat det kan vel være et godt salgsargumen?

Tlens camera module and terminal
Abstract
The utility model discloses a Tlens camera module and a terminal, comprising a lens, a Tlens module, a lens holder, a photosensitive chip and a circuit board.

The utility model has the following advantages:

(1) Put the lens module inside the camera, so the lens module is close to the surface of the circuit board, which is convenient for signal transmission, so the reliability is good, and it can effectively avoid the problem of the lens module breaking when the camera falls;

(2) Since the Tlens module is close to the surface of the circuit board, the common lens holder can be inlaid with conductive metal sheets to realize the electrical connection between the Telens module and the circuit board. Compared with the LDS process laser engraving conductive circuit to realize the The way the circuit board is electrically connected, the utility model has the advantage of low cost.

In this embodiment, since the Tlens module 3 is placed inside the camera module, it has the advantage of good reliability. At the same time, since the lens module 3 is placed inside the camera module, the lens module 3 is close to the surface of the circuit board 7, so the ordinary lens holder 2 is used to inlay the conductive metal sheet 5 to realize the electrical connection between the lens module 3 and the circuit board 7. Compared with the method of laser engraving the conductive circuit using the LDS process to realize the electrical connection between the Tlens module 3 and the circuit board, the Tlens camera module described in this embodiment has the advantage of low cost.

As shown in FIG. 4, in this embodiment, the electronic components include a photosensitive chip 1, a driving chip 10, etc., and the driving chip 10 is electrically connected to the Tlens module, the photosensitive chip 1 and the connector 9 respectively. The Tlens module 3 mainly receives the driving power provided by the driving chip 10 through the conductive metal sheet 5 embedded in the lens holder 2, so as to deflect the internal curvature and achieve automatic focusing. The driving chip 10 mainly drives the Tlens module 3 through instructions fed back from the photosensitive chip 1 and an external device.

The photosensitive chip 1 is used to receive and process external images and transmit them to the external device through the connector 9. The connector 9 is used to connect the Tlens camera module with an external device. If the Tlens camera module is used on a mobile phone, the external device is a mobile phone.

In this embodiment, a terminal includes the Tlens camera module as described in this embodiment.

In this embodiment, the terminal includes a mobile phone, a tablet circuit, a palmtop circuit, a notebook computer, and other wearable devices. The foregoing is only an example and not an exhaustive list, including but not limited to the foregoing terminal.

Denne tar kaka! Oppo!
Også denne er funnet av RNJG!
Sendt inn april 2021, godkjent for noen dager siden. Det er kjapt!

Smartphone og mange andre applikasjoner har behov for et kamera som kan måle distanse til et objekt, og vise dette i all slags lysforhold. Problemet med 3D og ToF-kameraene i dag er at de ikke funker på lengre avstander, i alle fall ikke godt nok. Modulene bygger mye, tar stor plass, koster flesk og har alt for treg fokusering. VCM drar strøm, gir dårlig stabilitet, interfererer med andre moduler og mye mer. Dette har Oppo bestemt seg for å løse.

Og løsningen er da...

TLens!

TLens løser alt dette, gir lav byggehøyde og fremheves som en svært god løsning. Og ikke minst, dette oppsettet skal være vesentlig billigere enn dagens ToF-kameraer!

Se f.eks dette, de tar helt bort diskusjonen om TLens, Tlens, tlens eller t lens, dette er poLights TLens:
"In this embodiment, the first lens 20 may be a tunable lens (Tunable lens, T lens) module, or may also be referred to as an auto-focus actuator: TLens (Tuneable Lens). Specifically, the first lens 20 includes a substrate 23 close to the light source 10, and the substrate 23 is used to carry other components. The transparent elastic member 24 is disposed on the side of the substrate 23 away from the light source 10. The transparent elastic member 24 is light-transmissive and has certain elasticity. The optical film layer 25 is provided on the side of the transparent elastic member 24 away from the substrate 23, and the optical film layer 25 is used for placing other structural members. The piezoelectric ceramic 26 is arranged on the side of the optical film layer 25 away from the substrate 23. The optical film layer 25 is used to provide piezoelectric ceramics 26 on the transparent elastic member 24. Optionally, there is a distance between the orthographic projection of the piezoelectric ceramic 26 on the substrate 23 and the orthographic projection of the transparent elastic member 24 on the substrate 23, so the piezoelectric ceramic 26 may pass through the optical film layer 25 without the transparent elastic member 24."

Se dette om sammenligningen med annen tech:

"Compared with the related technology, two transmitting ends are not required, which simplifies the structure of the optical sensor. And no motor is needed, and there is no need to reserve too much space for the lens, thereby reducing the volume of the optical sensor and reducing the cost."

Litt om problemet de løser:

"At present, a typical TOF structure includes a transmitter (Tx) and a receiver (Rx). The light emitted by the light source at the emitting end (such as a Vertical-Cavity Surface-Emitting Laser (VCSEL)) passes through various components (such as a collimator, Diffractive Optical Elements (DOE), and a homogenizing element). (Diffuser)) Then, it can be projected on the observation object in the form of speckle or flood light, and the diffuse reflection light of the speckle light or flood light reaches the sensor through the receiving end to complete the signal collection, and finally obtain the depth information of the observation object. Among them, the horizontal resolution of the floodlight scheme is high, and it is suitable for dark light environments. And in the close range, the depth point cloud information with rich details can be calculated; but as the irradiation distance becomes farther, the energy of the illuminating light drops sharply, and it is easily affected by the ambient light, which makes it impossible to detect the depth information of distant objects; In addition, the power consumption of the module is relatively high, and the signal-to-noise ratio of the sensor is low. The energy density of the speckle scheme is higher, and it can be projected to a greater distance, and the point cloud information of distant objects can be obtained. However, due to the limited number of speckles, the corresponding point cloud is relatively sparse and lacks the point cloud of the target object. detail.

In summary, we are currently developing a 3D optical sensor that is compatible with both speckle and flooding solutions to solve the problems of high power consumption, insufficient working distance, low reflectivity, and lack of information on surfaces such as specular reflection, and improve optical The overall performance of the sensor. There are usually two schemes: the first scheme directly uses two emitters, one speckle emitter and one floodlight emitter, and the switch between speckle and floodlight is completed by combination. However, this structure is large in size, high in cost, and complex in assembly. Doing so will undoubtedly make the module complex, burden the overall module volume, and increase the cost. The second solution is to switch between speckle and flood functions in one transmitter. For example, multiple lenses are used, and then the distance between the light source and each lens is adjusted by moving the lenses, so as to achieve the purpose of defocusing and switch between speckle and flood. However, this solution requires motor drive and space for the lens to move. Therefore, the size of the structure of this solution, and there are problems with VCM rated stroke, posture difference, and hysteresis. The speckle size matching in the speckle mode needs to be matched. Solve and so on."

Og potensialet:
"The electronic device 2 provided by this embodiment includes, but is not limited to, mobile phones, tablet computers, notebook computers, palmtop computers, personal computers (Personal Computers, PCs), personal digital assistants (Personal Digital Assistants, PDAs), and portable media players (Portable Media Players). , PMP), navigation devices, wearable devices, smart bracelets, pedometers and other mobile terminals, and fixed terminals such as digital TVs and desktop computers. Optionally, this application uses the electronic device 2 as a mobile phone for schematic description.

Helt rått at Oppo nå, i tillegg til all jobbingen med selfiecam både i notch og under skjerm, faktisk mener at TLens knuser dagens ToF- og 3D-teknologi!

https://worldwide.espacenet.com/patent/search/family/076713682/publication/CN113113836A?q=Cn113113836a

Tusen takk til RNJG for deling av funn. Dette er helt rått, og gir oss nå muligheten for TLens både foran og bak i smartphone...!

Kjekt å se at Oppo fortsetter å patentere nye løsninger med Tlens😇👍 Takker for deling og synspunkter🙂

Takk så mye for god info😃. Får håpe at det kommer noe gøy nå fremover ang kursen

Flott å se at linsa blir mer og mer aktuell i et av hovedkameraene på baksiden. Har ventet på dette. Har vært mest om frontkamera (selfiekamera) hittil. Det må da komme guiding fra poLight på Q2. Eller at en av oss stiller et spørsmål.

Revidert: Altså som linse i sensor til hovedkamera. Se mer under.

TLens er ikke en kandidat til store sensorer/hovedkamera pdd., da TLens silver (og premium) er rett og slett for liten. Dette patentet omhandler en ToF-sensor (time of flight) som "hjelper" hovedkameraoppsettet med å finne fokuslengder m.m. TLens vil ikke bli aktuell for større sensorer før en eventuell linse materialiserer seg utifra MoU-en som ble inngått i oktober(?) i fjor. Selskapet har selv guidet bakkamera medio 2023.

Selfiekamera som add-in er fortsatt det som ligger fremst i løypa.

Riktig det, TLens er enda ikke aktuell til de største hovedkameraene.
TLens silver er kompatibel med sensorer av en viss størrelse. Dersom størrelsen på sensoren øker, så vil ikke linsen være så stor at det kommer inn nok lys til at hele sensoren får nok nok innlys. Da blir det ikke mer effekt enn det en sensor på ca 1/3" ville gitt. For litt siden så var 32Mp en uttalt begrensning for Tlens silver.

MEN; det foregår en rivende utvikling innen sensorer. Med en fortetning på "sansecellene" til sensoren så blir sensorene myyyye mer lyseffektive. Isaksen har bekreftet at Omnivision OV60 kan gi hele 60MP oppløsning i bilder tatt med TLens silver! Det er faktisk en god del rimelige modeller som ikke har større hovedkamera enn dette.

I tillegg er det slik at alt som er beskrevet til nå gjelder for kamera som er bygget på dagens oppsett. Med andre prinsipper så kan dette økes.

I tillegg så har faktisk poLight Tlens Platinum ferdig utviklet. Den finnes tilgjengelig for ingeniørsamples, så det er ting som er kommet langt.

På sikt er det likevel TLens sin nye og større versjon, som ofte omtales som MoU-prosjektet, som er det virkelig store. Denne har de til hensikt å bygge så stor at den kan brukes som linse i de største hovedkameraene med type stor sensor.

Denne siste er det funnet flere patenter fra noen OEMs som kan passe, og det er særlig et par som ser ut til å bygge som periskop med optisk "superzoom", som de kaller det.

Mye spennende i utvikling altså, men akkurat nå er det viktigste å få bekreftet innpass i de MINSTE kameraene, altså selfie😉. For, uansett om TLens silver selges til et selfiecam eller et bakcam, så er prisen poLigjt får den samme, og selfie gir med mulighetene for ny selfiestandard en raskere inntjening et bakkamera gjør.

Takk for refresh/info om ulike linser til hovedkamera. Tenker sensorbrikken blir liten nok om ett år slik at Tlens kniver om salget der også.

"Transparent tunable optical elements with structurally-modified electroactive polymer"

Dette er tenkt særlig inn mot AR-briller, og er svært aktuelt;

0043] The present disclosure is generally directed to optical elements, and more particularly to optical elements that include a structurally-modified electroactive polymer layer. The electroactive polymer layer may be capacitively actuated to deform the optical element and hence modify its optical performance. By way of example, the optical element may be located within the transparent aperture of a liquid lens, although the present disclosure is not particularly limited and may be applied in a broader context. By way of example, the optical element may be incorporated into an active grating, tunable lens, accommodative optical elements, or adaptive optics."

Og litt videre:
"0055] Liquid lenses can be used to enhance imaging system flexibility across a wide variety of applications that benefit from rapid focusing. According to certain embodiments, by integrating an actuatable liquid lens, an imaging system can rapidly change the plane of focus to provide a sharper image, independent of an object's distance from the camera. The use of liquid lenses may be particularly advantageous for applications that involve focusing at multiple distances, where objects under inspection may have different sizes or may be located at varying distances from the lens, such as package sorting, barcode reading, security, and rapid automation, in addition to virtual reality/augmented reality devices.
[0056] The following will provide, with reference to FIGS. 1-26, a detailed description of methods, systems, and apparatuses for forming actively tunable optical elements that include a structurally-modified electroactive polymer and exhibit partial or complete transparency. The discussion associated with FIG. 1 and FIG. 2 includes a description of modified strain and force figures of merit compared to transmissivity for various piezoelectric polymers and piezoceramics."

The object side surface of the electro-deformable layer and the image side surface of the light guide layer are closely adhered by gluing, so as to avoid gaps or falling off. Compared with the traditional automatic focusing method of the lens, that is, the physical focusing mode with a clear imaging surface is realized by moving the entire lens group by the focusing screw. The electro-deformable layer is not affected by temperature and does not produce mechanical vibration, avoiding complicated calibration Process and reduce the autofocus response time.

√In some embodiments, the light guide layer is made of flexible polymer, and the electro-deformation layer is made of piezoelectric material.

The electro-deformation layer is made of piezoelectric material. The piezoelectric material has an inverse piezoelectric effect, that is, when a variable electric field is applied to the piezoelectric material, the piezoelectric material will produce mechanical deformation. , The piezoelectric film will produce mechanical deformation and disappear along with it. By energizing the electro-deformation layer, the electro-deformation layer is deformed by force through the inverse piezoelectric effect, thereby making the electro-deformation layer The curvature radius of the object side and the image side changes to realize the function of optical focusing. Compared with the screw focus mode, the electro-deformable layer is not affected by temperature and does not generate mechanical vibration, avoiding a complicated calibration process and reducing the autofocus response time.
