Title: Image coder and image coding method
Inventor: KOINO MASAKI
IPC: H04N19/126
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To obtain a high S/N in the image compression coding employing an adaptive differential pulse code modulation ADPCM. SOLUTION: Digital image data are fed to a differential pulse coding modulation DPCM circuit 10, where a difference from an adjacent pixel is calculated. The calculated difference is fed to an ADPCM circuit 12 and quantized by increasing/decreasing a quantization width by using plural thresholds. Specifically, when the quantization width exceeds a threshold MAX, the quantization width is subjected to increment, and when the quantization width is less than a threshold MIN, the quantization width is subjected to decrement. The quantized difference is fed to a Huffman coding circuit 14, where the difference is compression-coded and outputted. The quantization depending on the difference is attained by adopting plural thresholds and undesired fluctuation in quantization width is suppressed due to a hysteresis characteristic to obtain a high S/N.
