Image processing device and image processing system

Abstract

According to one embodiment, an image processing device includes a control signal generator, a selector, a memory, and a combined image generator. The control signal generator is configured to detect a synchronization pulse from a vertical synchronization signal in each of a plurality of video signals and configured to generate a first control signal indicative of selecting one video signal of the plurality of video signals of which the synchronization pulse is detected in turn for a predetermined period. The selector is configured to select the one video signal of the plurality of video signals according to the first control signal. The memory is configured to store the selected video signal in one region of a plurality of regions corresponding to the selected video signal in a predetermined format. The combined image generator is configured to generate a combined image by combining the plurality of video signals stored in the plurality of regions.
