摘要： In image signal processing, the color saturation values of image signals are accumulated within each of a plurality of color saturation calculation regions by a color saturation accumulator circuit 13, and the image signals obtained in a color saturation calculation region in which the result of the color saturation value accumulation thus performed by the color saturation accumulator circuit 13 is low are accumulated for each of image signal types C1 to C4 by an image signal accumulator circuit 14. Based on the results of this accumulation performed for each of the image signal types C1 to C4, constants with which to counterbalance the amounts of light transmitted for the image signals C1 to C4 are determined and fed to a transmitted light amount corrector circuit 1. Moreover, based on the results of the color saturation value accumulation performed for each color saturation calculation region by the color saturation accumulator circuit 13, weight factors are determined and fed to a luminance signal generator circuit 6. The luminance signal generator circuit 6 receives, through a VLPF 4, the image signals for which the amounts of light transmitted have been counterbalanced by the transmitted light amount corrector circuit 1, and also receives image signals produced by smoothing the image signals obtained from one set of a plurality of adjacent pixels after another through the VLPF4 and an HLPF 5. The luminance signal generator circuit 6 produces luminance signals by adding together these signals with the weight factors assigned thereto.

摘要： An automatic exposure control camera always permits a subject to be photographed with appropriate brightness regardless of a front-lighted, back-lighted, or over-front-lighted condition. The area to be photographed is divided into 64 regions. The camera determines the average Yav64 of brightness over all the regions, the average YavU32 of brightness in the regions constituting the upper half, the average YavL32 of brightness in the regions constituting the lower half, the average YavD1 of brightness in regions in which brightness is lower than the average Yav64, the average YavD2 of brightness in regions in which brightness is lower than the average YavD1, the average YavB1 of brightness in regions in which brightness is higher than the average Yav64, and the average YavB2 of brightness in regions in which brightness is higher than the average YavB1. Based on the ratios between these averages, the camera distinguishes among a front-lighted, a back-lighted, and an over-front-lighted condition and controls the exposure of an image sensor accordingly.

摘要： In a color separator circuit, edge detection filters detect an edge encountered in the horizontal direction. When the image signals corresponding to the thus detected edge are processed, selector circuits 12a to 12c select outputs from small-tap-number color separation filters 8a to 8c and 10a to 10c, respectively. When the image signals corresponding to the remaining portion other than the edge are processed, the selector circuits 12a to 12c select outputs from large-tap-number color separation filters 9a to 9c and 11a to 11c, respectively. A ratio calculator circuit 16 calculates, from the luminance signals fed from adder circuits 13a to 13c, the value by which a multiplier circuit 18 performs multiplication. The multiplier circuit 18 multiplies, by this value calculated by the ratio calculator circuit 16, the color separation signals added together by an adder circuit 17 so that, of all the color separation signals of which there are two kinds, those of one kind are vertically interpolated.

摘要： A movement control system useful for an apparatus comprising a movable member movable between two positions, a motor and a sensor device for producing an output value which changes during the movement of the movable member. The control system drives the motor in a first amount so as to move the movable member from one of the two positions to the other position and thereafter drives the motor in a second amount to move the movable member toward said one position when the output value of the sensor device remains unchanged. When the sensor device produces a changed output value, the system drives the motor in a third amount to move the movable member toward said one position. Subsequently, the system drives the motor in a fourth amount when the output value of the sensor device is different from the output value before the motor is driven in the first amount, so as to move the movable member toward said other position. The system drives the motor in the second amount when the output values are the same so as to move the movable member toward said one position.
