PURPOSE:To prevent an incorrect focusing by providing a sensor consisting of plural light receiving elements arranged in a string shape, and performing a focus adjustment positioning the sensor at a point based on the maximum counting value out of the changing points of a sensor output found before the focus adjustment CONSTITUTION:A film 1 is exposed with light from a light source (a) passed through a lens (b), and furthermore, after it is passed through a lens (c), is introduced selectively to a screen (h) side or a reading side 3 with a light path switching mirror (d) Before an automatic focusing operation is performed, a system controller 17 moves an image sensor (f) little by little with a subscan motor (g), and fetches the binary changing point count value of each line with a binary value changing point counter 20, and finds a value Th in which the maximum value of the count value is multiplied by a prescribed factor, for example, 70% Next, the sensor (f) is restored to its start point, and is moved again, and the movement of the sensor (f) is terminated at a point where the count value exceeds over the value Th At the point, the automatic focusing operation is performed with a picture signal on the line Thus, the incorrect focusing can be prevented

PURPOSE:To avoid a malfunction of an automatic focus controller by dividing the video signals passed through plural BPFs of different bands into a speed control system and a direction indication system with addition of a filter peak detecting circuit and an adder circuit to both systems respectively and also driving a lens focus control system with the outputs of both circuits. CONSTITUTION:A filter detection NAM circuit 21 detects the peak of each filter, and the effects of the depth can be avoided by transmitting the outputs of amplifiers 15-17 through the circuit 21. Here a motor driving circuit 8 is controlled by a speed control circuit 22 so that the driving speed of a motor 5 is set at a low level toward a focal point D0 compared with a case where an out-of-focus degree is large to the point D0. Thus the focusing control of a lens 1 is carried out smoothly. The output of an adder circuit 18 undergoes the synchronizing wave detection through a synchronizing wave detection circuit 19 and is turned into a switch input to the focus direction. Then the circuit 8 is controlled by a switch circuit 20, and the focusing direction is decided.
