IMAGE SENSOR WITH IN-PIXEL BACKGROUND SUBTRACTION AND MOTION DETECTION
An imaging system includes a pixel array configured to generate image charge voltage signals in response to incident light received from an external scene. An infrared illumination source is deactivated during the capture of a first image of the external scene and activated during the capture of a second image of the external scene. An array of sample and hold circuits is coupled to the pixel array. Each sample and hold circuit is coupled to a respective pixel of the pixel array and includes first and second capacitors to store first and second image charge voltage signals of the captured first and second images, respectively. A column voltage domain differential amplifier is coupled to the first and second capacitors to determine a difference between the first and second image charge voltage signals to identify an object in a foreground of the external scene.
SENSING DEVICE, SIGNAL PROCESSING SYSTEM, AND METHOD OF CONTROLLING SENSING DEVICE
In a sensing device that retains a code indicating access destinations, a data amount of the code is reduced. In a pixel array unit, a plurality of areas each include a predetermined number of pixels are arrayed. A reference access code retention unit retains a reference access code for designating, as access destinations, some of the pixels in a specific area among the plurality of areas.
