WebOct 19, 2015 · The camera lens projects a miniature image of the outside world onto the surface of a light sensitive image sensor located inside and at the rear of the camera. This image sensor is covered with millions of photosites. Most photosites are overlaid with red, green or blue filters. During the exposure light from scene plays on the photosites. WebReducing unwanted image artifacts is another benefit of the IMX556. Because the IMX556 is a CMOS sensor it performs better against smearing and blooming versus CCD ToF sensors. Smearing and blooming can cause erroneous 3D data and is created when the charge overflows the pixel well capacity, spilling into adjacent pixels.
