Abstract:
A moving image judging apparatus for displaying an image on a video display monitor comprising: (a) a line sensing camera including a line sensor having more pixels than a number of vertical scanning lines for the video display monitor, and which produces input video signals of images of moving objects by scanning said moving objects using line sensor elements to scan in a direction orthogonal to a moving direction of said moving objects, (b) a video image processing apparatus which converts said input video signals from said line sensing camera into digital image data signals, stores said digital image data signals into a memory sequentially according to a time sequence, then reads out said image data signals stored in the memory area necessary for displaying and converts them into analog output video signals as output signals, (c) a controller for said image processing apparatus to select an operation mode and to control the apparatus, and (d) an external output apparatus which displays said analog output video signals from said image processing apparatus on the video display monitor, wherein said image processing apparatus comprises: (p) a memory means for storage purpose having a first memory area for said digital image data signals to be stored sequentially according to the time sequence and a second memory area for information data concerning said digital image data signals, said memory means comprising a dynamic random access memory (DRAM), (q) a memory means for display purpose where image data necessary for displaying image data and drawing information data to be composed with said image data are written in and afterwards read out in synchronization to a video displaying signal, comprising an image data display memory where the image data and the information data are stored, a time display memory where time, time lines and information on images are stored as said drawing information data, and a scale and measurement display memory where a scale line for time measurement of displayed images are stored, (r) an output means which composes said image data and said drawing information data to convert to analog output video signals, and (s) a control means which has a connection interface to external equipment, selects an operation mode according to a selection command from said controller, controls said signal conversions from analog to digital and digital to analog, controls said data composition of image data and drawing information data, controls reading and writing of said memory means for storage purpose and said memory means for display purpose, and generates said drawing information data.
