Title: Image pickup system
IPC: H04N5/228
Filed: 1966-07-27
Abstract: 1,139,580. Television. SONY CORP. 27 July, 1966 [28 July, 1965], No. 33725/66. Heading H4F. In a system for avoiding image resolution degradation due to residual charges on the photoelectrically sensitive screen of a television camera tube of the vidicon type, the screen is intermittently exposed to light images of objects to be televised and is electronically scanned a plurality of times between each exposure to ensure complete neutralisation of the charge pattern resulting from an exposure and to provide image video signals from which all signals except those produced during the first scan following each exposure are subsequently gated out. In the embodiment of Fig. 1, screen 16 of tube 10 is intermittently exposed by rotating shutter 26 for exposure times less than the duration of a frame scan of screen 16 by an electron beam from gun 14. Electromagnetic pick-up 34 provides pulses P 1  for synchronizing oscillator 40 with the rotation of shutter 26, and frequency dividers 42 and 50 provide vertical and horizontal synch pulses for electron beam deflection circuitry 48. The frequency division is such that four frame scans occur per revolution of shutter 26. Cascaded bistable circuits 52, 54, 56 are driven by the frame (vertical) synch pulses Pv and pulses P 1  and provide (i) pulses P 3  which blank off the electron beam during the first scan (in which the exposure is made) and (ii) pulses P 4  which open video gating circuit 58 during the second scan only (i.e. during the first scan following the exposure). The video signals, which are taken from screen 16, combined in unit 64 with synch pulses and gated by circuit 58, thus appear at output terminal 25 intermittently but may be converted to a continuous signal train by recording them on a rotary magnetic sheet and reproducing them successively a plurality of times.
