Data processing apparatus having function for registering abstract image

Abstract

A data processing apparatus is disclosed for electronically filing image data including large drawing data at a high speed. An operator sets up a registration mode in the filing apparatus, and enters a retrieval code for retrieving desired image data. These operations are effected by using related keys on a keyboard. A CPU in the filing apparatus carries out a predetermined check on the entered retrieval code, and stores the checked retrieval code in a main memory. A scanner picks up the image data to be retrieved. The image data is stored in a page memory and a display memory, and displayed by a CRT display device. The operator checks the image data if it has a large size, for example, A1 or A2. If it has a large size, he designates necessity of the size reduction of the image data by a keyboard. In response to this designation, the CPU reads out the image data of one page as stored in the page memory. An enlarge/reduction circuit size reduces the image data to a small size--for example, A4--the size-reduced image data being subsequently band compressed by a CODEC, and stored in an optical disk by an optical disk device.
