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： 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 infrared ray receiving module receives an infrared signal (transmitted by an image display device) generated on the basis of a signal representing switching between right and left eye images. An input signal type automatic judging unit and a field frequency detecting and L/R distinguishing unit acquire data relating to shutter timing of a left eye liquid crystal and a right eye liquid crystal in liquid crystal shutter glasses from the received infrared signal. An operation field frequency determining unit generates decision data relating to shutter timing to be fed to the liquid crystal shutter glasses on the basis of predetermined conditions from the data relating to shutter timing newly obtained in succession, and holds the generated decision data. A liquid crystal driving pulse generating unit can cause the liquid crystal shutter glasses to perform a shutter operation using the held decision data when no decision data is generated because the predetermined conditions are not satisfied. Consequently, it is possible to maintain the shutter operation even if the infrared signal is blocked.

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.

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.
