摘要： 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.

摘要： An encoder is operable to encode input data to generate corresponding encoded output data. The encoder includes data processing hardware. The encoder compresses content associated with blocks or packets, so that the encoded output data is smaller in size than the input data.

摘要： 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 colour value change as compared with the corresponding pixels of the preceding processed frame exceeds a predetermined threshold, to exchange (8) the colour 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.
