The present invention relates to an image processor that is configured to compare a single frame included in the received signal with a preceding processed frame so as to detect changes. In order to enable the image being compressed in as compact a format as possible, the processor is configured to detect changes by dividing the pixels of a single frame into movement blocks and to detect the movement block as changed if in said movement block there is a given number of pixels whose color value change as compared with the corresponding pixels of the preceding processed frame exceeds a predetermined threshold, to exchange the color values of the pixels of the unchanged movement blocks in the frame under process for predetermined values and to generate a signal that indicates the changes.

Method for recognizing pattern, pattern recognizer and computer program
The invention relates to a pattern recognizer, which, in order to recognize the pattern fast and with lowest possible computing power, comprises a memory (12) for storing area-specific reference values (REF) calculated on the basis of image information of image areas containing parts of the pattern to be recognized, and a processor (14) that is configured to divide (15) a received image into areas, to calculate (16) reference values (REF) area-specifically on the basis of the image information of said areas, to compare (17) the calculated reference values (REF) with the reference values (REF) stored in the memory (12) and to indicate (18) that the pattern is recognized, in case in the received image there is found a part consisting of adjacent areas, where the reference values (REF) of the areas correspond, with sufficient accuracy, to the reference values (REF) stored in the memory (12).
The invention relates to an image processor configured to: receive an image, take area-specific samples (11) of the image information of the area and calculate (12) a reference value (REF) on the basis of the samples; store into a memory (16) or to transmit (17) the reference value (REF) calculated for an area and the area identifier (ALUE) area-specifically; check (13) whether the reference value (REF) obtained as a result of the calculation and the image information (INF) corresponding to it have already been stored in the memory (16) or transmitted (15); and to store into the memory (16) or to transmit (15) the calculated reference value (REF) and the corresponding image information (INF), if the reference value (REF) and the corresponding image information (INF) have not been stored into the memory or transmitted previously.

The present invention relates to a video image processor (1) that is configured to compare (7) a single frame included in the received video signal (3) with a preceding processed frame so as to detect changes. In order to enable the video being compressed in as compact a format as possible the processor (1) is configured to detect (7) changes by dividing the pixels of a single frame into movement blocks and to detect the movement block as changed if in said movement block there is a given number of pixels whose color value change as compared with the corresponding pixels of the preceding processed frame exceeds a predetermined threshold, to exchange (8) the color values of the pixels of the unchanged movement blocks in the frame under process for predetermined values and to generate a signal (4) that indicates the changes.
