  • Image processing device and method
    Patent number: 8203618
    Abstract: An image processing device including a camera, a discrete signal processor (DSP) and an output device is disclosed. The camera provides image data for the DSP to process. The DSP samples sub-image data to generate a first image processing signal, discrete cosine transforms the first image processing signal to generate a second image processing signal, uses a quantization table to quantize the second image processing signal to generate a third image processing signal, zig-zag scans the third image processing signal to generate a fourth image processing signal, and Huffman codes the fourth image processing signal to generate an output image signal. The DSP adjusts a cut point of a next fourth image processing signal according to the size of the fourth image processing signal so as to control the size of a next output image signal. The output device outputs the output image signal.
