Abstract:
1. An image processing apparatus comprising: a memory circuit for storing image data; a read circuit for reading at least first image data, second image data, and third image data from said memory circuit; a first processing circuit for producing fourth image data indicating a difference between said first image data and said second image data read by said read circuit; a second processing circuit for multiplying said fourth image data with a predetermined coefficient to produce fifth image data; a third processing circuit for adding said third image data and said fifth image data to produce sixth image data; a write circuit for writing said sixth image data to said memory circuit; a control circuit for executing a predetermined program to control said read circuit, said first processing circuit, said second processing circuit, said third processing circuit, and said write circuit in accordance with the execution of said program; and a selecting circuit for outputting said first image data, said second image data, and said third image data to a processing circuit designated by said control circuit among said first processing circuit and said third processing circuit.
