Now you see it: Sony picture taken with curved CMOS sensor

People are talking about Sony's first curved-sensor photo shown on Nikkei.jp, seen as a big deal because the company's technology signifies better-quality images and possibly cheaper lenses to come. This is capturing attention as the first picture taken with a Sony curved image sensor. The sensor that Sony has constructed is a prototype. As Nick Sutrich in AndroidHeadlines noted on Tuesday, the prototype sensor is a much smaller resolution than the full-frame sensors that Sony is to send off to production. Sheldon Pinto wrote in TechTree that "What it indicates is that Sony is pretty sure that the technology works and is effective compared to the standard sensors that are now used in everything from mobile phones to professional cameras."

What's wrong with flat, regular ? They have Petzval curvature. As a result, said Engadget, the workarounds from optical designers result in costly added elements to lenses. As Rishi Sanyal explained in DPReview, "The sensors inside digital cameras are - generally - flat. But curved sensors promise greater sensitivity, better image quality, and provide scope for simpler lenses." With Sony's approach you are going to see shorter, lighter lenses with larger apertures that let more light in. Curved CMOS sensors mimic the eye; the sensors, with their architecture, work the same way as the human eye to fix optical issues, with a similar level of curvature. IEEE Spectrum recently detailed some key benefits of a curved CMOS sensor: A curved CMOS sensor, because of the geometry, can be paired with a flatter lens and a larger aperture, which lets in more light. Photodiodes at the periphery of a are bent toward the center, so light rays hit them straight on. Strain induced on the sensor by bending alters the band gap of silicon devices in the sensor region, lowering the noise created by the current that flows through a pixel even when it is receiving no external light.

Mirrorless Rumors summed up the reaction of tech sites this week that the image in and of itself does not deliver startling impact but is of historical significance. "That image doesn't look exciting at all but it's precious because it's actually the first photo taken with a Sony curved sensor!"

Engadget said, as the first image shown from Sony's curved CMOS sensor, the image indicates "a possible new direction for its digital camera division." DPReview's Sanyal commented that "some may view this image as being 'historic' and others will appreciate the simple fact that Sony's curved sensor technology is not simply a concept in its early stages of development."

Earlier this year, Reuters reported that Sony held the largest share of the global CMOS (complementary metal-oxide semiconductor) sensor market in 2012 at 32.1 percent, according to Techno Systems Research.

Very interesting.

The complexity of lithography processes in producing a curved CMOS sensor are huge. All of the masks and processes that go with them will have to be re-engineered. But if they succeed in making this economically viable, the benefits will also be huge.

It is really very interesting, but I am not sure if this will be the great deal that Sony hopes.
However, the amount of this optical aberration depends on the focal length,
therefore, the full advantage exactly exists for one focal length.
For all other focal lengths there is, again, a correction of the lenses necessary.
I don't know if it is easier to do these corrections.

But wouldn't it be nice to have a flexible sensor, adapting with focal length of the lens? -
This is fiction, but, maybe, Sony's approach is a first step in such a direction.
