Description

3. Detailed Description of the Invention Technical Field The present invention relates to an image reproducing device, such as a digital copying device or an image output device that visually outputs an image from a host machine.

In conventional technology, for example, in a digital copying machine, an image of a document read by a scanner is stored as digital data in a storage device, which is sequentially read out and recorded as a hard copy by a printer.

Reading, storage, readout, and recording of such original images are controlled by a central processing system.

Conventional digital copying machines that use small processing systems such as microcomputers are equipped with only one set of image memory and related buses. Therefore,
For example, if a specific area is duplicated from a document image,
It has been difficult to efficiently perform various editing processes such as double extraction, which reproduces as separate images, and superimposition processing, which extracts multiple areas from a document image and overlaps them for reproduction. To perform such editing processing, for example, image data of a specific area of the original image data stored in a single image memory is read out and reproduced on recording paper, and this operation is performed multiple times. There was a need.

Therefore, it took time to complete the final image on the recording paper, which was not efficient.

Hereinafter, a specific explanation will be given based on an example of the final example 11.

Referring to FIG. 1, there is shown an embodiment in which the final IJI is applied to a digital copying apparatus. The water device includes a scanner 10 that reads a document image and forms an image signal,

The image control bus 16 is a bus that transfers image data from the scanner IO, image data to the printer 20, and related image control signals and synchronization signals. Control boards lOOa and 100b are connected. One image control board 100a is referred to herein as a main image control board, and the other image control board 1oOb is referred to as an optional image control board. As will be described later with reference to FIG. 2, there is no difference in the internal structure of the two.

In this embodiment, the image control boards 100a and 100b exchange image data with the scanner interface 14 and the printer interface 18, and also access memory boards 30a and 3Qb, which will be described later. In this embodiment, various methods are further implemented, such as double sampling, in which specific areas of a document image are duplicated and reproduced as separate images, and overlay processing, in which multiple areas are extracted from a document image and reproduced by superimposing them. This is an image control unit that performs editing processing.

A main memory board 30a corresponds to the main image control board 100a, and an optional image control board 100
Optional memory boards 30b are provided corresponding to the respective memory boards 30b. These are temporary storage devices a for accumulating image data. As shown in the figure, the main image control board 100a and the main memory board 30a are interconnected by a main nib bus 32a. Similarly, one feature of the option image control board 100b and the option memory board 3Qb is that the two edit buses 32a and 32b, which are interconnected by the option nib bus 32b, are separated from each other. Nibite paths 32a and 32b are connected to corresponding memory boards 30a and 30b, respectively.
7! A bus that transfers memory data to be loaded or read, its addresses, and memory control signals.

Image control boards 100a, 100b and memory boards 30a, 30b are also connected to a system bus 34, which in turn is connected to a CPU board 36. The CPU board 36 is equipped with a central processing system that controls the operation of the entire apparatus, and the system bus 34 transfers system data, system addresses, and system control signals.

Additionally, a parallel/serial converter +10 for converting serial image data from the image control bus 16 into parallel data and outputting the parallel data to the NIBIT bus 32 is connected as shown.

Image data read from a document by the scanner IO is serially transferred from the scanner interface 14 through the image control bus, converted into parallel data by the serial/parallel converter 110, and output to the nibbit bus 32. This is stored on memory board 30a or 30b. Further, the image data stored in the memory boards 30a and 30b is read out as parallel data to the NIBIT bus 32,
The data is converted into serial data by the parallel-to-serial converter 10 and sent to the image control bus 16. This is transferred from the printer interface 18 to the printer 20 and printed out. The addresses of memory boards 30a and 30b are:

As this image processing condition 42, for example, a sampling area A of the original image 200 is specified. 'Therefore, the CPU board 36 sets the main option switching signal 3 days to the main side (224), thereby setting the image processing condition data to the extraction/generation control section 102 of the main image control board 100a.

Similarly, the CPU board 36 sets the image processing conditions 42 for the optional image control board '1oOb (22B

Effects According to the present invention, the image data control unit and the image memory are divided into a plurality of groups, and each group is connected independently through a path of each system. Therefore, for example, by extracting a specific area redundantly from a document image, or by extracting multiple different areas from a document image almost simultaneously and storing these image data in respective image memories, various editing processes can be performed quickly. can be done. In this way, image editing processing can be performed efficiently using a plurality of systems of control units and image memories.
