摘要： Methods of processing an image signal and signal processing devices can lessen a work load of a processor for processing a photographed image signal, can process photographed image signal, and can display the image signal in real time. The method includes performing first image processing on a first image frame to generate first image data, performing second image processing on the first image frame to generate second image data, outputting the first image data based on a first vertical synchronization signal, causing image processing not to be performed on a second image frame subsequent to the first image frame, and outputting the second image data. Accordingly, the JPEG image and the thumbnail image for the photographed image are generated by the image signal processor, thereby lessening a work load of the processor and improving image processing speed.
