摘要： An image processing apparatus is disclosed which inputs/outputs an image in which image data items having different quantities of information for each pixel are mixed with one another. The information quantity for each of the image data items and information about the I/O positions are stored in a corresponding manner. When data is input, data is converted into the proper information quantities in accordance with input position, for storage. When data is output, the stored image data is converted into output data in accordance with the respective information quantities. As a result, the memory capacity can be reduced, the flexibility can be improved at the time of use and the memory can be used efficiently.

摘要： An image processing apparatus is disclosed which includes circuitry for selectively applying variable gamma corrections to an image signal during both on-line and off-line modes of operation. In the off-line mode, the apparatus operates to simultaneously correct image signals for non-linearities produced by both an input device and an output device. In the on-line mode, correction is made for the non-linearities of the input device and a separate correction is made for the non-linearities of the output device. Such operation allows the apparatus to process linear data in the on-line mode.
