1. An apparatus for detecting a moving body comprising:
- pickup means for picking up an object and delivering video signals thereof,memory means for storing values of spatial filter function in corresponding relation to the picture elements of the pickup means,means for successively reading out from the memory means the values of spatial filter function corresponding to the picture elements in synchronism with scanning by the pickup means,means for multiplying the read-out spatial filter function values by the video signals from the pickup means,means for integrating the multiplied signals for a required area, andmeans for calculating required information as to the object from the result of integration.

Abstract
A moving body detecting apparatus comprises a television camera for picking up an object and delivering video signals thereof, a memory for storing values of spatial filter function in corresponding relation to the picture elements of the television camera, a multiplier for multiplying the video signals by the spatial filter function read out from the memory in synchronism with scanning by the television camera, an integrator for integrating the multiplied signals for a required area, and a calculating device for calculating the desired information as to the moving body, such as its speed, from the result of integration.
