IMAGE PROCESSING SYSTEM
First Claim
1. An image processing system, comprising:
- a plurality of camera moduleseach including an imager configured to acquire an image at a timing of a vertical synchronization signal repeated at a fixed cycle, and a phase controller configured to control a phase of the vertical synchronization signal, andeach configured to output the vertical synchronization signal together with a corresponding one of image signals of images of different imaging fields;
an image synthesizing unit configured to synthesize, based on the image signal and the vertical synchronization signal output from each of the plurality of camera modules, the images acquired by the plurality of camera modules to generate a single synthesized image;
a video picture output unit configured to output, as a video picture, synthesized images continuously generated by the image synthesizing unit to a monitor;
a phase monitoring unit configured to compare the phases of the vertical synchronization signals output from the plurality of camera modules; and
a relative phase control unit configured to output a relative phase control signal to the phase controller of each camera module at a predetermined cycle such that the vertical synchronization signals of the camera modules monitored by the phase monitoring unit are synchronized with each other, whereinthe image synthesizing unit synthesizes the images acquired by the camera modules at a timing of a synchronized and controlled vertical synchronization signal to generate a single synthesized image.
