Filed: 1984-08-23
Abstract: PURPOSE:To eliminate a delay due to scanning line conversion and to minimize an error of simulation by simulating information quantity before a scanning line of an inter-frame forecasting error of a TV signal is converted. CONSTITUTION:A buffer simulator 7, in which an inter-frame forecasting error signal is supplied to a terminal 7a and a coding signal is given to a terminal 7b respectively, calculates information quantity accumulated in a scanning line converting circuit 3 and outputs a simulation information quantity signal.

Title: Automatic electronic flash
Inventor: HIRATA SHINJI
IPC: H05B41/32
Filed: 1985-08-08
Abstract: PURPOSE:To control the lighting state of a flash discharge the effectively by controlling the collector current of a transistor (TR) connected to the flash discharge tube in series according to the value and time of a constant current supplied to the base. CONSTITUTION:The value and supply time of the constant current supplied from a constant current supply circuit 16 to the base of the TR7 connected to the flash discharge tube 1 in series are controllable by operating a trigger circuit 15. At this time, the discharging current of the tube 1 becomes equal to the collector current of the TR7 determined by the value of the constant current outputted by a constant current source I1, etc., because the TR7 operates in an unsaturated region. When the photodetection quantity of a dimming circuit 23 which photodetects reflected light from a subject reaches a specific value, the circuit 23 turns ON a switch element 22, so the constant current from the circuit 16 by-passes the TR7, which then turns OFF to stop the light emission. Then, when the shutter speed is set to a value at which the open aperture value is not obtained and the dimming circuit 20 is enabled to operate, the output terminal of a switch circuit 18 is selected by a microcomputer.
