Latest Patents

Kawamura holds a patent for a "Video compression coding apparatus and video compression." The objective of this invention is to provide a video compression coding apparatus that can compress video data effectively while minimizing any degradation in video quality. The apparatus utilizes a DCT (Discrete Cosine Transform) section to transform input video data into DCT coefficients, which are then quantized by a quantizing section. This quantized data is subsequently processed in a variable length coding section, where it is compression-coded in a block unit corresponding to a field or frame. The invention includes a code quantity detecting section that monitors the code quantity of the coded data and communicates this information to a quantization control section. This section determines the quantization level for the next block based on a predefined control characteristic, ensuring optimal compression without sacrificing quality.
