Abstract: PURPOSE:To output a video image kept horizontal irrespective of the inclination of a video camera by detecting the angle of the inclination of the photodetecting surface of an image pickup element, and making the range of prescribed size in the picture of the photodetecting surface a video image output range, and displacing the video image output range to generate a video signal in accordance with a detected signal. CONSTITUTION:The video signal obtained by image pickup at a photodetector part 1 is stored in a memory 4 by a data input/output circuit 3 after being digitized by an A/D conversion circuit 2. The data input/output circuit 3 executes the write-in and the read-out of a digitized video signal in the memory 4. A horizontality detection circuit 5 detects and outputs the inclination because the photodetector part 1 inclines against horizontality, and detection output is controlled by a horizontality correction and control circuit 6. In the data input/output circuit 3, the video signal stored in the memory 4 is read out while displacing it in accordance with the inclination. Thus, the video output becomes capable of being kept always horizontal.
