摘要： An image compression unit includes a block divider that divides image data into a plurality of blocks, a DCT portion that subjects the image data of each block to DCT, a quantization factor output portion that outputs a quantization factor as a numerical value indicative of fineness of quantization, a correction value computation portion that computes a correction value that is determined uniquely according to a position of a block of image data, a quantizer that quantizes the data having been subjected to DCT, based on a value obtained by multiplying the correction value by the quantization factor, and an encoder that encodes the quantized data and outputs compressed data. This configuration makes it possible to provide an image compression/decompression unit that is capable of varying a compression ratio in a frame, without encoding compression parameters of each block.

摘要： A fixing apparatus of an embodiment of the invention includes an auxiliary pressure member to press a belt to a heat roller side. A belt mechanism to integrally support the belt and the auxiliary pressure member is rotated so that the belt is spaced from the heat roller except for a necessary time. The temperature gradient characteristic of the surface temperature of the heat roller is compared with a reference temperature gradient characteristic, and a correction value of power supplied to a coil is estimated. The correction value is added to the supply power obtained from the detection result of a sensor, and control power for controlling an inverter drive circuit is obtained.
