Disclosed in the invention is a programmable visual
chip-based visual
image processing system, comprising an
image sensor and a multilevel parallel digital
processing circuit. The
image sensor mainly includes a
pixel array, an analog preprocessing circuit array and an analog-to-
digital conversion circuit array; and the digital
processing circuit consists of a
parallel processing unit array with an M*M pixel level, a
parallel processing unit array with M*1 rows, an on-
chip artificial neural network and a reduced instruction processor dual-core subsystem. According to the provided
system, high quality image collection with high speed and multilevel
parallel image processing are realized and several high-speed intelligent visual application can be realized by
programming; and compared with a traditional
image system, the provided
system has advantages of high speed, high integration, low
power consumption and low cost. Moreover, the invention brings forward an embodiment for realizing the above-mentioned system as well as several high-speed intelligent visual
image processing algorithms based on the embodiment. High-speed
motion detection, high-speed gesture identification and rapid
face detection are included; and the
processing speed can reach 1000 frames per second. Therefore, a requirement of high-speed real-
time processing can be met.
