Abstract:
An image signal processing apparatus, comprising:imaging means for receiving an object light and generating moving image signals representing moving images; storing means for storing moving image signals generated by said imaging means, the stored moving image signals having movement with respect to each other; combining means for receiving the moving image signals which are newly-generated by said imaging means and the moving image signals read out from said storing means, and for combining the moving image signals newly-generated by said imaging means and the moving image signals read out from said storing means, said combining means including coefficient means for multiplying by a coefficient the moving image signals read out from said storing means; recording means for recording moving image signals, said recording means being capable of recording the moving image signals generated by said imaging means and the moving image signals output from said combining means; and control means for controlling said storing means so as to store the moving image signals generated by said imaging means for a first predetermined time in recording of the moving image signals by said recording means, said control means controlling said storing means according to an instruction for stopping the recording of the moving image signals by said recording means so as to stop writing the moving image signals, generated by said imaging means, into said storing means a second predetermined time after a stop of the recording of the moving image signal by said recording means and to store the moving image signals for the first predetermined time plus the second predetermined time, said control means controlling said storing means and said combining means so that the moving image signals are read out from said storing means for the first predetermined time plus the second predetermined time and that said combining means combines the moving image signals newly-generated by said imaging means and the moving image signals read out from said storing means for the first predetermined time plus the second predetermined time.
