Patent JP-H0329582-A (JP)
Title: Coding system for picture
Inventor: KUSAO HIROSHI
IPC: H04N19/196
Filed: 1989-06-27
Abstract: PURPOSE:To prevent the reduction in the processing speed by deciding a round-off bit number of a quantization orthogonal transformation coefficient in a way that all data quantity of the quantization orthogonal transformation coefficient after round- off is smaller than a predetermined threshold level and sending the round-off bit number and class classification information of each block as header information. CONSTITUTION:The round-off control section 8 compares all bit number of the quantization orthogonal transformation coefficient counted by a quantization data bit number counter 7 with a predetermined threshold level. The threshold level gives a lower limit of the compression rate of a picture and specifies the allowed maximum value as a data quantity after compression. When all bit number of the quantization orthogonal transformation coefficient is larger thant the threshold level, a round-off control section 8 controls a low-order bit round-off section 5, the low-order bit of the quantization orthogonal transformation coefficient is rounded off and the result is sent as a code data. In this case, the quantity of the round-off of the low-order bit is decided by the round-off control section 8 so that all bit number of the quantization orthogonal transformation coefficient after round-off is smaller than the threshold level. Thus, the decrease in the processing speed is prevented.
