Title: Image pickup method
Inventor: FUKUDA HIROSHI
IPC: H04N5/225
Filed: 1982-12-24
Abstract: PURPOSE:To pickup an image of an object which runs at a variable speed without blurring and to prevent the adverse influence of headlights by providing a means which detects the position and speed of the subject, a reflecting mirror which rotates following up the subject and forms its image at an image pickup part, and a hood with a light shielding part. CONSTITUTION:When a vehicle 1 passes through a point A, the detection signal (a) of a photodetecting element 12 and a clock (c) allow a counter 14 to start counting and its value is integrated successively by a D/A converter 15 to input a signal (d) to a latch 16. When the vehicle 1 passes through a point B, a photodetecting element 12' inputs a detection signal (b) to the latch 16 to stop the integration. This value is in inverse proportion to the speed, so the reflecting mirror 20 rotates in conformty to the speed by a driving circuit 18 through an inverting amplifier 17, and the reflected light alpha from the picture of the vehicle from the point B to the point C enters a camera 2 to take the picture. A picture of the oblique line part 1a of the vehicle 1 is taken without halation by being shielded by the light shielding part 33b from the direct light from the headlights 4 and 4'.
