The method includes at least the following steps. A current encoding frame is received. Pixels in a current encoding frame are grouped on a line-by-line basis, and the grouped pixels are packed into pixel segments. Complexity information of a current pixel segment is calculated according to the pixels therein and neighboring pixels thereof. The current pixel segment is respectively encoded in a differential pulse-coding modulation (DPCM) mode and a truncation mode to generate a DPCM bitstream and a truncated bitstream according to a quantization parameter (QP). Either the DPCM bitstream or the truncated bitstream is selected and outputted according to the complexity information. An amount of bits used by the current pixel segment is feedback to calculate a new QP corresponding to a next pixel segment to be processed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of fixed-rate line-based embedded video compression and image processing apparatus using the same","description":"The disclosure proposes a method of fixed-rate line-based embedded video compression and an image processing apparatus using the same method.
