High speed pipeline image processing for digital photoprinter

摘要

An image processing apparatus subjects image data photoelectrically read out by an image reading apparatus to predetermined image processings and outputs the read-out image data as image data to be recorded. The image processing apparatus includes a plurality of memories for storing image data read out by the image reading apparatus; an image processing unit for reading the image data from the memories and for carrying out the predetermined image processings by pipeline processing; a condition setting unit for setting image processing conditions in the image processing unit; an image data bus for inputting and outputting the image data; and a control bus for inputting and outputting control data. The image processing apparatus permits a scanner to continuously read images, and a printer to continuously record the images of an application requiring high speed output of finished prints (i.e., a digital photoprinter). Thus, finished prints can be effectively output at high speed.
