Abstract

PURPOSE:To enable to display the state of change in a picture, by unifying the positive and negative pulses obtained from an analog signal differentiated to one polarity and producing a profile signal of picture in synchronizing it with a clock signal. CONSTITUTION:The differentiation circuit 11 produces the positive and negative pulses through the differentiation of video signal input to the terminal 10. This pulse is converted into a digital signal only positive at the wave shape circuit 12. This signal is fed to the waveform conversion circuit 13 to be converted into the pulse with a given width or more and latched to the input processing circuit 16 in synchronizing with the clock signal. The signal of the circuit 16 is stored in the memory circuit 17 at the part (a) of the output timing of the control circuit 20 and read out at the part (b), in serial-parallel conversion at the output signal processing circuit 18. The signal converted into parallel at the circuit 18 is fed to the profile correction circuit 19 in synchronizing with the clock signal. The circuit 19 takes the correlativity of 2-bit in the input bit to produce the profile signal and to control the heat sensing recorder 21.
