Abstract: A moving image judging apparatus for displaying an image on a video display monitor. A line sensing camera includes a line sensor having more pixels than a number of vertical scanning lines of the video display monitor, and produces input video signals of images of moving objects by scanning the moving objects using line sensor elements to scan in a direction orthogonal to a moving direction of the moving objects. A video image processing apparatus converts the input video signals from the line sensing camera into digital image data signals which are stored into a memory sequentially according to a time sequence, then read out for displaying and converted into analog output video signals as output signals. The image processing apparatus includes a memory for storage purpose having a first memory area for the digital image data signals to be stored sequentially according to the time sequence and a second memory area for information data concerning the digital image data signals.
