Image Processing: towards a System on Chip
Abdelhafid Elouardi,Samir Bouaziz,Antoine Dupret,Lionel Lacassagne,Jacques-Olivier Klein,Roger Reynaud +5 more
TL;DR: To face the high data flow induced by the computer vision algorithms, an alternative approach consists in performing some image processing on the sensor focal plane, the integration of pixels array and image processing circuits on a single monolithic chip makes the system more compact and allows enhancing the behavior and the response of the sensor.

Active Pixel Sensors: Are CCD's Dinosaurs?
TL;DR: ActivePixel Sensor (APS) as mentioned in this paper is a detector array technology that has at least one active transistor within the pixel unit cell, which eliminates the need for nearly perfect charge transfer, which makes CCD's radiation'soft' and difficult to use under low light conditions, difficult to integrate with on-chip electronics, difficulty to use at low temperatures, and difficulty to manufacture in non-silicon materials that extend wavelength response.
