Sony: new CMOS sensors for HDR movies on smartphones

While the video community longingly on the implementation of global shutter as next technological advancements immersion coil in the field waiting for (consumer) imager, announces Sony today the next generation of CMOS sensors, aiming still mainly higher light output and a more effective layout of the circuits. The latter allows among others. to build small sensors with more pixels, but also the readout speed should be accelerated. This is achieved by the established structure of rueckseitigen exposure is optimized again ("Stacked CMOS"). Here, the wiring completely migrated into a rear sensor layer, so that is saved on the layer with the light-sensitive pixels square section (see figure). Due to the separation of functions according to Sony is basically twoeach independently fabricated chips can each be specialized for their task. The PIC1 made to bring this new principle of sensors with two special features. Firstly, by using "RGBW Coding", in which additionally recorded on a white pixel RGB values u200bu200bwill not decrease the sensitivity of the sensors, although the pixels fail 1.12m with very small - according to Sony is that the noise performance of 1.4 m pixels correspond. Second, the sensors provide a "HDR Movie" function to optimize images for large brightness contrast. Here are the images read out with two different exposures and then combined: VY = fM2xYCcbV5U be specifically uae during three "Stacked CMOS" sensors for smart phones. are available. The
