To easily design and actualize a video camera by integrating three functions for improving spatial resolution of macroscanning, making photosensitive response uniform among respective sites, and compensating vibration by deflection member control in the same assembly.
A two-dimensional photosensitive site 14 placed on the image plane of an optical system outputs accumulated electric charges to a corrector 38 at a specific frequency. The corrector 38 receives gains by sites and correction values for deviation stored in memories 44 and 46 in synchronism with a signal, makes the photosensitive response uniform, and outputs it to a shaper 43. A deflection member 24 on an optical path is driven by motors 26 and 28 which are controlled with the output of a control unit 58, performs two-dimensional deflection cycles only for a 1st specific part so as to perform spatial oversampling, and further deflects an image by only all intervals in a 2nd cycle. A processor device 48 compares the sites to calculate gain differences and deviation in response among the sites. Vibration is detected by gyros 34 and 36 to correct the deflection quantity.
