Abstract

The invention relates to the transmission and processing of color images. The purpose of the invention is to reduce the sweep time and power consumption. A decrease in the required power while reducing the sweep time is achieved by increasing or decreasing the capacity of the memory blocks 10, 11 depending on raster information. For this, the coded information from the raster information bus 21 is supplied to the raster decoder 15, which generates signals for controlling the address selection block 16, the address control block 19, the zone control block 20 of the blocks 10, 11 of the memory. In addition, the device provides for accurate synchronization of reading and writing data into memory blocks 10, 11 with the speed of the carrier. For this purpose, a position sensor 18 and a pulse shaper 22 are used, which form clock signals for the d-res account block 17, transducers 5, 6, 7 and; blocks 10, 11 memory. 2 Il.

Description

The invention relates to the transmission and processing of color images and may be used in digital image processing devices.

A device for synchronization of data of spatially displaced developmental systems is known, in which motion compensation is performed as follows (German Patent No. 2754503, Cl, G 03 B 31/02, published in 1978).

The information obtained by three deploying systems at spatially separated locations is delayed after demo- dulation in such a way that the spatial movement of the carrier is compensated and the output is quasi-parallel information.

The disadvantages of this device are TOMj that there is no synchronization of the data interleaving, since the delay blocks do not depend on the speed of the carrier. In addition, it is impossible to selectively retrieve data of information between spatially separated deployable systems. The device works as follows.

The purpose of the invention is a reduction in time,

change of sweep and consumed power-spaced separation.

The rotating systems 1-3 provide the image signals of the respective color image channels, which are converted into converters 5-7 into digital image signals. When moving the deployment systems along the carrier, intermediate storage of data from deployment systems 2 and 3 is necessary. Moreover, deployment system 3 requires a larger capacity of memory block 11 than block 10 of deployment system 2 memory. Data from the scanner is output without intermediate storage.

Data input and output control of memory blocks 10 and 11 is controlled by control unit 14 using input 8 and 9 and output 12 and 13 gates. Since it is possible to scan the image points of the original when choosing various raster distances, the maximum capacity of memory blocks 10 and 11 is used. For

the address control unit 19, the sample control block 20 of the zones of the memory blocks 10 and 11, depending on the raster information, the memory capacity increases or decreases. Thereby, a reduction in the power requirement is achieved while reducing the sweep time.

In order to delay the digitized data and the subsequent parallel output of the data of individual developmental systems, it is necessary to synchronize the blocks 10 and 11 of the memory with the speed of the data carrier. To solve this problem, a position sensor is used that converts the location information of the deployment systems relative to the carrier 4 into signals that are fed through the pulse shaper 22 to the synchronous inputs of the transducers 5-7 and the address counting unit 17. In this way, a one-to-one correspondence is provided between the coordinate point of the data carrier 4 and the address of memory blocks 10 and 11.
