New type sensor dumps green subpixels for less noise




Manufacturer Sensor Aptina has a new camera sensor for mobile phones unveiled. This sensor has no regular layout with red, green and blue subpixels, but exchanges the green pixels for colorless variants, which should produce less noise.

Almost all the camera sensors are made up of red, green and blue sub-pixels, which together form a regular pixel, in a so-called Bayer arrangement. In addition, often a red, a blue and two green sub-pixels are present. The new Clarity + technique of Aptina the green subpixels replaced by colorless pixels, which can be and reduces the amount of noise in the picture, more light is captured writes DPReview . The information that is normally supplied by the green pixels is now obtained by the information of the red and blue pixels bring the data from the ‘clear pixels. Deducted

According Aptina this improves the signal-to-noise ratio and reduces the noise level considerably in pictures. In that the sensor is more sensitive, can be faster shutter speeds are used, for example, what is beneficial to the making of HDR images. The manufacturer claims that the new sensor type in terms of sharpness and color reproduction is similar to existing Bayer sensors. Aptina has not announced any commercial products based on Clarity + technology, but a fully working prototype is already made.
