Title: Photometric circuit of flash discharge gun
Inventor: TAKEMATSU YOSHIYUKI
IPC: G03B15/05
Filed: 1982-08-16
Abstract: PURPOSE:To eliminate the need to use circuit parts with high dielectric strength for a photometric circuit and to improve IC ratio, by forming the photometric circuit independently of a light emitting circuit which includes a main discharge capacitor and a flash discharge tube. CONSTITUTION:When a power source switch 2 is turned on, a DC-DC converter starts oscillating to charge capacitors 6, 18, and 12. When the main discharge capacitor 6 is charged up to a preset discharging voltage, a neon lamp 21 lights to turn on a switching circuit 22, and a starting circuit 19 and a buffer circuit 23 receive a circuit voltage from a battery power source 1. When a synchronizing switch 20 is closed in this state, a starting voltage generated by the starting circuit 19 turns on an SCR10 and a timer 24 starts operating. A trigger circuit is operated by the conduction of the SCR10 and the flash discharge tube starts light emission. The timer 24 applies a constant voltage to the photometric circuit, which starts photometry. When the photometric signal of the photometric circuit rises up to a specific value, an SCR11 is made unconductive and the flash discharge tube 7 stops the light emission.

IPC: G06T11/40
Filed: 1992-06-02
Abstract: PURPOSE:To extract an area at fixed accuracy independently of the size of an unfilled part due to an inter-frame difference by previously setting up a picture element value having an area-filling condition value on an optional point in an area to be filled with dots as an initial value and repeating scanning plural times by a window having a certain size to allocate the area-filling condition value. CONSTITUTION:In the case of filling a still part with dots and extracting a moving area, the inter-frame difference between the brightness signals of two television frames which are continuously inputted is binarized and extracted. The initial value for area-filling is set up in the still part and a window shown by a short dashes line in a drawing is moved in accordance with a previously determined window scanning route. When the initial value for area-filling exists in the periphery of the center point of the window, the center point is set up as an area-filling value and then the window is moved only by one picture element to search the existence of a picture element having the area-filling value around the center point. This processing is repeated several times along the window scanning route.
