【Abstract】 This paper proposes a scheme for the design of high quality and low price color digital camera based on CMOS image sensor and general digital signal processor(DSP). The hardware and software architectures are introduced. The key technologies, including automatic focus control, automatic exposure control, RGB interpolation and fast discrete cosine transform(DCT) are presented in detail. By this digital camera, we can get high quality color photos with the resolution of 1 024×768 pixels.更多还原
