摘要： The exposure time calculator calculates exposure time of image sensor based on an aperture value corresponding to a diaphragm and brightness of an object. The predetermined time calculator calculates predetermined time based on a focal length of a lens and a predetermined coefficient. The shooting mode determining unit determines execution of multiple-exposure shooting to obtain a composite image of the object by obtaining multiple object images and then combining the multiple object images in a case where the exposure time is equal to or longer than the predetermined time. The motion detector detects motion among the multiple object images in the multiple-exposure shooting. The predetermined coefficient calculator updates a predetermined coefficient based on the detected amount of motion.

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： 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 image-taking apparatus generates an output image from a photographed image obtained by photographing and displays this output image on a display screen of a display section. The image-taking apparatus includes a recognition processing section for recognizing a specific subject (facial region of a person, or a facial component such as eyes) included in the photographed image. Referring to results of this recognition, the image-taking apparatus evaluates the dimension of the specific subject in each photographed image. If the dimension evaluated is relatively large, a relatively small magnification ratio to be employed upon the generation of the output image from the photographed image is provided. If the dimension evaluated is relatively small, a relatively large magnification ratio to be employed upon the generation of the output image from the photographed image is provided. As a result, the dimension of the specific subject in the output image is kept substantially constant.

摘要： Based on, for example, the image at the start of a movie, a thumbnail image is tentatively generated and is stored in a header file. If a predetermined triggering condition is fulfilled during movie shooting, a thumbnail image is generated from the frame image at the timing that the triggering condition is fulfilled, and the thumbnail image existing in the header file is replaced with the newly generated thumbnail image. The triggering condition is fulfilled, for example, if, after zooming-in, the angle of view has been kept fixed for a predetermined period or longer, or if the focus has been kept locked for a predetermined period.
