Abstract: The purpose of the present invention is, in a horse race or a motorboat race, to display the progress of the race (trail) of each horse, by obtaining analysis data of a plural number of patrol images provided around the race course, by acquiring position information of each horse at the moment and by tracking the specific horse through judging similarity between consecutive pictures of said patrol image. The position information analyzing and displaying method for each horse or boat or the like of the present invention, for continuously captured race images, identifies each horse or boat or the like by similarity analysis and tracks continuously the trail of each horse or boat or the like in said racing images, and also analyzes said position information of each horse or boat or the like by using the positional relationship with the fixed position information in said images, in order to display the trail of each horse or boat or the like.

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.
