Abstract
This paper presents a new image sensor with programmable multiresolution readout capability. The proposed image sensor can output data at varying resolutions. Differing to our previously reported spatially variant sampling sensor, which sub-samples without filtering, in the multiresolution sensor blocks of the pixels are averaged and read out so the new sensor does not suffer from aliasing effects. The resolution can be controlled by varying the block size. We made a prototype of 64×64 pixels
