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.
