摘要:
An image processing apparatus includes a processing unit for processing an image signal into which an original document, after being exposed to light, is photoelectrically converted, a compression module for compressing image information processed through the processing unit, a memory for storing image data compressed by the compression module, a control unit for setting a diversity of image processing modes, and a predicting module for predicting an image compression rate used by the compression module. The predicting module predicts the image compression rate of an image after being processed according to the image processing mode set by the control unit.

An original document reading apparatus includes a first control portion for performing a first control wherein documents are transported at a first document interval in the event that a detected occupying capacity is less than a detected unused capacity. The first control portion also performs a second control wherein documents are transported at a second document interval which is greater than the first document interval in the event that the detected occupying capacity exceeds the detected unused capacity. A second control portion continuously activates an exposure portion under the first control, and intermittently activates the exposure portion under the second control.

An image signal processing apparatus includes an input unit for inputting an image signal for each of at least one input line, and a conversion unit for converting the input image signal for each input line into parallel converted image signals for a plurality of output lines and for outputting the converted image signals. A processing unit is then provided for performing image processing for each of the converted image signals for the plurality of output lines.
摘要:
An original is allowed to pass on an exposing glass along a conveying path, thereby exposing and scanning a front surface of the original and reading an image by a CCD. A back surface of the original is subsequently fed to the exposing glass along a conveying path and is allowed to pass on the exposing glass, thereby exposing and scanning the back surface of the original. The image data read by the CCD is stored into an image buffer. The order of address columns to read out the image data on the front surface and the order of address columns to read out the image data of the back surface are made opposite. Thus, a copying apparatus which can efficiently expose and scan both of the front and back surfaces of a both-side original is provided.

High density portions of images are preferentially expressed when a plurality of images constructed by multivalue image data are synthesized. A plurality of different images are synthesized, wherein overlapped multivalue image data of pixels among multivalue image data constructing the images are compared and the multivalue image data of which one of the images should be preferentially used is determined in accordance with the comparison result.
