abstract

In order to overcome the limitation of the image processing speed of the conventional video camera system, we have designed and constructed a column parallel vision (CPV) system. The CPV system realizes an intelligent and general purpose image processing capability with higher frame rate within 1 millisecond (i.e. 1000 frames/s). The system mainly consists of three parts; a sensing unit, a parallel processing unit and a control unit. The sensing unit has a 128x128 photodiode (PD) array, 128-column parallel amplifier array and A/D converter array to achieve high-speed frame rate and has been integrated in a CMOS chip. The parallel processing unit is composed of fully 128x128 processing elements (PEs) to perform a real-time image processing. The control unit has functions of PD/PE control and interface to the host computer. We have confirmed that the CPV system can process general image processing functions within a few ten microseconds. We have also demonstrated that the system can be worked as a tracking system with high-speed feedback loop and have evaluated the accuracy of the position calculation for the desired target.
