Alors là je vais faire le cynique, mais... BIEN FAIT.
Panasonic faisait les meilleures TV au monde pour les cinéphiles, parce qu'ils étaient devenus meilleurs que Pioneer dans la maîtrise de la techno plasma.

@Zygonyx a écrit:Une nouvelle très préoccupante pour les "petits" fabricants d'APN ne disposant pas de leur propre ressource de capteurs...

Dans une interview retirée depuis sa publication par IR, Mr Tanaka de Sony dévoile "à moitié" les intentions de ce dernier de NE PLUS VENDRE de capteurs, mais les garder pour leurs propres produits.
A la Canon, quoi..... sachant que Sony a tellement pris en parts de marché, que l'option est peut-être devenue tentante pour eux...

Chic, en reflex, il ne resterait plus qu'une alternative à Canon: Sigma. Comment dire... j'ai beau être partisan de la techno Foveon, ça reste toutefois un gros problème d'utiliser ces capteurs dès qu'on manque de lumière...

@Mistral75 a écrit:Ce n'est pas ce que dit l'article. Sony Semiconductors continuera à fournir des capteurs à ses clients. L'interviewé est quelqu'un de Sony Imaging. Il indique que les développements faits par Sony Semiconductors à la demande de Sony Imaging sont réservés à Sony Imaging et ne sont pas partagés avec les autres clients de Sony Semiconductors (de même que ceux effectués à la demande de Nikon sont réservés à Nikon, etc.).

Rien de bien nouveau, si ce n'est que Sony Imaging a désormais une masse suffisante pour financer des développements à façon qui lui sont dédiés et non plus les mutualiser, en financement comme en usage, avec d'autres constructeurs d'APN.

Imaging Resource a écrit:[Ed. note from Dave Etchells: This was new information for me; as far as I'd been aware, Sony's camera division would get access to the latest sensor designs as soon as they came through the design and production cycle, while other companies could buy the same sensor a year later. While this might once have been the case, it appears that Sony currently reserves dome level of their sensor technology exclusively for us in their own cameras.]

Imaging Resource a écrit:[An extended editorial note from Dave Etchells: This has been the subject of a *lot* of misinformation, misinterpretation and speculation on the 'web, so let me attempt to set the record straight...

This at first glance was new information for me; since as far as I had been aware, other manufacturers always eventually got access to the same sensors that were used in Sony cameras. Instead, Tanaka-san was saying that there would be some developments that were co-developed by Sony's camera division, and that those would of course remain proprietary.

(I'd initially said that I thought there was a time delay involved, between when Sony could use the most advanced sensors in their own cameras vs when competing camera makers had access to the tech, but they informed me that there was no public position to that effect, and particularly no timeline for that sort of thing. - I'd said that other makers got access to the most advanced sensors a year after the Sony camera engineers did, but there appears to be no such official timeline.)

What clearly seems to be the case, though, is that Sony camera engineers are able to work with Sony's sensor engineers, to develop unique system architectures that take advantage of their unique integration capabilities, when creating their own cameras.

It's important to note that this isn't in any way a matter of holding back "higher-quality" sensors to disadvantage competitors. When it comes to quantum efficiency and fundamental noise levels, we're up against fundamental physical limits, with all the manufacturers. The limiting factor in extremely high-ISO noise levels isn't an issue with the silicon or a particular fab process, it's the "shot noise" that results from random variations in how many photons arrive at each pixel in a given time. If Sony were to somehow dial back specs in the sensors they offer competing camera manufacturers, other sensor makers would rapidly step in to fill that gap.

Instead, Sony's advantage is that their camera engineers can collaborate directly with their sensor-engineering team, to jointly develop new system architectures that fully leverage their exceptional integration technology.

Completely apart from this conversation with Tanaka-san, I've long been aware that Sony has integration technology driven by the smartphone market, that goes well beyond commodity sensor tech in the camera space. In the camera world, it takes significant changes in system architecture to take advantage of this. We've recently seen Sony's collaborative advantage in this area with the A99 II and A6500. (Read my interview with Kimio Maki and Takashi Kondo from Photokina 2016, for more about their "front-end LSI" technology that's deployed in those cameras.)

Recently, Sony's gone well beyond what we saw in the A99 II and A6500, though, with an announcement of three levels of circuit-stacking in the smartphone sector, now incorporating massive amounts of DRAM directly integrated with the sensor chip and logic. In the small-sensor world, this now allows full-HD resolution video capture at 1,000 frames/second, and full-resolution still image capture at 19.3 million pixels per frame, at 120 fps. (The announcement linked above not only discloses 1,000 fps FHD recording, but also the ability to intelligently switch between normal recording and super slow-mo, when the sensor system detects rapid subject motion.)

So let's be clear: Sony isn't somehow holding back their "good" sensors for use in their own cameras; it's instead more about taking advantage of the fact that their camera and sensor engineers are able to collaborate with each other, developing new camera architectures that take advantage of their unique integration capabilities. This isn't news, it's just that current advances mean that overall system architecture plays a bigger role than it did in the past.]

Andrew Reid pour EOSHD a écrit:As of April 1st 2017 at the start of the new financial year, Panasonic will change the name of the old camera division from AVC Networks Company to Connected Solutions Co. Ltd, and transfer Lumix under the umbrella of the Appliances Company division. VARICAM will remain at Connected Solutions Co.

(...)

TVs also belong under the Appliances division at Panasonic (...)

Meanwhile, Panasonic is likely to divest from their joint sensor business with Israel’s TowerJazz (who along with Panasonic likely supplied image processors and sensors for the Leica SL and Q) and discontinue a number of lower-end compact cameras and camcorders, whose appeal are somewhat diminished.
