PROBLEM TO BE SOLVED: To simultaneously acquire entire video of low resolution and partial video of high resolution at high speed. SOLUTION: A solid-state imaging device 10 has a pixel array 12 of high resolution where a plurality of light receiving elements is arrayed in high density. A low resolution entire video scanning part 14 outputs entire video data in low resolution by entire read and scan where the resolution of the pixel array 12 is lowered. A high resolution partial video scanning part 16 outputs partial video data in high resolution with partial reading and scanning where the high resolution of the pixel array 12 is maintained. A switching part 20 switches the low resolution entire video scanning part 14 and the high resolution partial video scanning part 16 within a frame period to successively output low resolution entire video data and high resolution partial video data at a speed equal to or higher than the video rate. A video segmenting processing part 32 automatically determines the position to segment high resolution video in the next frame based upon the low resolution entire video data and instructs the high resolution partial video scanning part 16.
