The sensors inside digital cameras are - generally - flat. But curved sensors promise greater sensitivity, better image quality, and provide scope for simpler lenses. Recently, Sony showed off some examples of curved image sensors, including (tantalizingly) a full-frame chip. Device manager Kazuichiro Itonaga claims: "The team has made somewhere in the vicinity of 100 full-size sensors with their bending machine. We are ready." Read on to learn more about this exciting new tech, how it imitates the human eye, and how it may find its way into consumer products.
Canon has released a short video produced with a unique full frame CMOS sensor. Announced in March, it's a sensor dedicated to extreme low light video recording with unusually large pixels. The test subject? A group of Yaeyama-hime fireflies on Japan's Ishigaki Island. Click through to read more.
Consumers need to think about sensor size rather than pixel count, says Aptina's Sandor Barna, because larger image sensors are likely to appear in all types of devices. Barna, the Vice President and General Manager of sensor maker Aptina's Consumer Camera Business Unit, spoke to us about the challenges facing compact cameras, the niche that will continue to exist for them, and hints that more large sensor compacts are on their way.
Sensor maker Aptina has given more details of its Clarity+ technology that it claims will offer a 1EV improvement in sensitivity over conventional sensors. The company believes it has found a way to use clear pixels to capture more light while retaining the image quality of a standard Bayer sensor. Although initially intended for smartphone sized sensors, the company says it could have applications in larger formats. Find out more over at connect.dpreview.com
Fujifilm and Panasonic have announced the joint development of a sensor technology that combines a light-sensitive coating on top of a CMOS chip. The companies claim higher dynamic range and sensitivity than current CMOS sensors, along with the ability to receive light at steeper angles - making it easier to design cameras with wide-angle lenses and allowing lenses to be mounted nearer to the sensor. The announcement extends from the work Fujifilm has been conducting on organic (carbon-based) photo-senstive materials and combines it with CMOS underpinnings developed by Panasonic. The result is a chip that uses CMOS technology only for circuitry - with the organic layer taking over the role of converting light into electrons.
Canon has developed a 35mm full-frame CMOS image sensor designed for low-light video capture. The 16:9 sensor features a 1920x1080 pixel array, meaning each pixel measures a huge 19 microns along each edge - 7.5 times larger than the ones in the EOS-1D X. The large pixels and low readout-noise circuitry allow the sensor to capture light around 10 times less bright than current CCDs used for astronomy. The sensor will first be shown in public at a security show in Japan.
Sensor maker Aptina has announced it has signed a patent cross-license agreement with Sony, that provides each company with access to the other’s patent portfolio. This agreement gives two prominent sensor makers access to some of each other's technologies for future development of cameras and other imaging products.
US technology company Rambus has unveiled 'Binary Pixel' sensor technology, promising greatly expanded dynamic range for the small sensors used in devices such as smartphones. Current image sensors are unable to record light above a specific saturation point, which results in clipped highlights. Binary Pixel technology gets around this by recording when a pixel has received a certain amount of light, then resetting it and in effect restarting the exposure. The result is significantly expanded dynamic range from a single exposure.
Much ado has been made about the sensor technology rumored to debut along with HTC's newest handset launched today, the HTC One. While rumors of stacked sensors were predictably wide of the mark, HTC is taking a clever approach to improving camera phone quality by betting on fewer but larger pixels captured by a 4.0MP 1/3" sensor, which are similar in size to those found in enthusiast compact cameras, and which HTC is calling 'ultrapixels'. Combined with a fast F2.0 lens and optical image stabilization, the HTC One's specs hold promise for better low-light photography - an area where mobile phones have fallen notoriously short.

Panasonic has devised a method to increase the sensitivity of image sensors, by replacing the near-universal colour filter array with prism-like 'Micro Color Splitters' to generate colour information. The key advantage is that all of the incoming light is directed to the sensor, instead of half or more being absorbed by the colour filter dyes. This promises to deliver images with less noise in low light. The development is published in the journal Nature Photonics, and outlined in a press release on Panasonic's website.
Following the announcement of its 1" sensor, we spoke to Aptina's Sandor Barna, who believes these larger sensors could save the compact camera by offering a leap in quality that smartphones can't compete with. Barna, the Vice President and General Manager of Aptina's Consumer Camera Business Unit, told us about the unfilled gap in the market that 1" sensors can address, explained the freedoms that the larger format gives the company's designers, and why this is currently best exemplified by a product it wasn't involved in: The Sony RX100.
