According to a study from the United States, "In this paper, we report a 64 x 64 active pixel sensor, designed for low-power image sensing for wireless sensor networks. The proposed image sensor computes the temporal difference between two continuous frames and communicates them in an address-event representation format."
"The image sensor is capable of computing 30 temporal-difference frames per second (fps) and consumes 1 mW with a 3-V power supply. Light-intensity images are also available as an output at a speed of 60 fps. The image sensor was fabricated in a 0.5-mu m bulk CMOS process. The fabricated sensor was tested with various stimuli to evaluate its ...
