Abstract: PURPOSE:To enable the reception of a message addressed to one's own from anywhere, by checking whether a number sent first from a caller is a password, or a voice mail number, and reproducing the message based on an ID number decided result. CONSTITUTION:An ID number decision circuit 5 decides whether the number sent first from a user coincides with data stored at a password storage part 3, and a voice mail number storage part 4. When a subscriber listens to the message sent to himself/herself, the subscriber dials his/her own subscriber telephone number, and after the connection of a line to a voice mail system, he/she dials his/her own password. The ID number decision circuit 5, when a sent dial number coincides with the data stored in the password storage part, switches a bus to a message reproduction circuit 8. The message reproduction circuit 8 reproduces the message stored in a message storage part 9, and sends it out to the subscriber.

In the case the correlation coefficient is proximate to 1, it is estimated that the position of the image surface is displaced in accordance with the detected time, so that it is exactly judged that the subject is the moving body. Furthermore, in the case the correlation coefficient is proximate to 0, which is judged as the case that the position of the image surface is fluctuated, and it is accurately judged that the subject is a still body in any case. Namely, whether the subject is the moving body or not is exactly decided by deciding the correlation coefficient by the use of the threshold in a moving body decision means 3.

Abstract: PURPOSE:To discriminate if a vertical synchronizing frequency is 50Hz or 60Hz with no adjustment, by forming a saw toorh voltage from a vertical synchronizing signal synchronizingly separated from a received TV signal and forming the waveform of the saw tooth wave to an exponential function or a function of higher order. CONSTITUTION:A composite synchronizing signal A of a received TV signal is integrated at an integration circuit 1, a vertical synchronizing signal part B is picked up and a transistor (TR)2 is turnwd on at a constnt level or more. Resistors (R)10 and 11 and the TR12 constitute a reference current source, and when the TR2 is turned off, a capacitor (C)4 is charged with Rs 17 and 18 and a TR19. When a voltage across the C4 is increased, a TR16 connected with Rs 13-15 is conductive, a base voltage of a TR19 is lowered and a current in the C4 is increased. Thus, a voltage being an exponential function is generated across the C4 and if a vertical synchronizing freqency is 50Hz or 60Hz can be discriminated with TRs 5 and 6. Further, the center value of the amplitude difference is applied to the base of the TR6 with TRs 24 and 25 and a discriminated output 9 can be obtained with no adjustment.
