| 英文摘要 | A programmable vision chip with variable resolution and row-pixel-mixed parallel image processors is presented. the chip consists of a cmos sensor array, with row-parallel 6-bit algorithmic adcs, row-parallel gray-scale image processors, pixel-parallel simd processing element (pe) array, and instruction controller. the resolution of the image in the chip is variable: high resolution for a focused area and low resolution for general view. it implements gray-scale and binary mathematical morphology algorithms in series to carry out low-level and mid-level image processing and sends out features of the image for various applications. it can perform image processing at over 1,000 frames/s (fps). a prototype chip with 64 x 64 pixels resolution and 6-bit gray-scale image is fabricated in 0.18 mu m standard cmos process. the area size of chip is 1.5 mm x 3.5 mm. each pixel size is 9.5 mu m x 9.5 mu m and each processing element size is 23 mu m x 29 mu m. the experiment results demonstrate that the chip can perform low-level and mid-level image processing and it can be applied in the real-time vision applications, such as high speed target tracking. |
