Abstract
In an image processing apparatus which performs first and second operations, a first processor processes image data in correspondence to the first operation, while a second processor which processes image data in correspondence to the second operation. Further, a memory is shared by the first and second processors. A controller connects the first processor to the memory in the first operation and to connect the second processor to the memory in the second operation. For example, the above-mentioned first and second processors are constructed by a common device such as a field gate programmable array wherein a function thereof can be rewritten.
Claims15
An image processing apparatus which performs a first operation and a second operation different from the first operation, the image processing apparatus comprising:
- a first processor which processes image data in correspondence to the first operation;
- a second processor which processes image data in correspondence to the second operation;
- a memory shared by said first and second processors;
- and
- a controller which changes connection of said memory to said first and second processors to connect said first processor to said memory in the first operation and to connect said second processor to said memory in the second operation.
An image reading apparatus which performs prescan for acquiring document information before reading a document image and performs normal scan for reading the document image, the image reading apparatus comprising:
- a first processor which processes the data acquired in prescan;
- a second processor which processes image data acquired in normal scan;
- a memory shared by said first and second processors;
- and
- a controller which changes connection of said memory to said first and second processors to connect said first processor to said memory on prescan and to connect said second processor to said memory on normal scan;
- wherein said memory stores document information acquired in prescan and stores conversion data for conversion of the image data on normal scan.
An image forming apparatus which performs test print for printing predetermined pattern data and performs normal print for printing document image data, the image forming apparatus comprising:
- a first processor which generates the predetermined pattern data for test print;
- a second processor which processes image data for normal print;
- a memory shared by said first and second processors;
- and
- a controller which changes connection of said memory to said first and second processors to connect said first processor to said memory on test print and to connect said second processor to said memory on normal print;
- wherein said memory stores the pattern data on test print and stores conversion data for conversion of the image data on normal print.
