Abstract: An auto-exposure device of a camera which can generate a photograph which fits to an image of a photographing time band in the photographing of an evening scene, a morning scene and so on. The auto-exposure device comprises a split photo-metering device for photo-metering a plurality of split areas of an object field, a color temperature measurement device for measuring a color temperature of a light source for illuminating the object field, and an exposure calculation device for calculating an exposure value based on the output of the split photo-metering device and the output of the color temperature measurement device.

Abstract: A photometric device for use in a camera includes, but is not limited to, a segmented brightness measuring unit which segments a photographic scene of a camera into multiple areas and which outputs corresponding multiple photometric values. A spectral analysis unit performs spectral analysis of the spatial frequency of a photographic subject using the corresponding multiple photometric values output by the segmented brightness measuring unit. Also, a photometric computation unit computes photometric values based on the spectral pattern of the photographic subject output by the spectral analysis unit. The spectral analysis unit may be disposed within the photometric device, or may be located elsewhere in a camera's body.

Abstract: A camera is provided having a line-of-sight detecting device for detecting a line of sight of an observer, photometric means for detecting luminances of subareas into which a luminance detection area is partitioned, a selecting means for selecting a specific subarea from the plurality of subareas on the basis of information on the line of sight detected by the line-of-sight detecting means, and a calculating means for weighting the luminances of the plurality of subareas on the basis of the specific subarea selected by the selecting means.

Abstract: A photometric value compensating device corrects the influence on the photometric value of a mark or character superimposed in the finder field of a camera when the finder field is finely divided for photo metering and makes it possible to always obtain the proper exposure value. The photometric value compensating device includes a finely divided photo metering device that divides the photographic field into multiple areas and measures the light intensity or brightness in each area and transmits information based on the measured light intensity as a photometric brightness value. A photographic information display device superimposes photographic information inside the finder field. A correction area determining device determines the photometric areas for which photometric value correction is necessary based on the brightness of the photographic information displayed in the photometric areas of the finely divided photo metering device.

Abstract: This invention relates to a camera photometry system which uses accumulation-type photoelectric elements to output photometry information related to the brightness of the subject field. Its purpose is to provide a camera photometry system which has a simple structure and which contains a two dimensional photometry mechanism with a wide dynamic photometry range. A camera photometry system using this invention is composed of a two dimensional photometry mechanism made of multiple accumulation-type photoelectric elements, and an accumulation control mechanism which controls the accumulation time of the photoelectric elements, with the system structured so that the multiple photoelectric elements are grouped in separate areas and the accumulation control mechanism is positioned at each of these areas and controls the accumulation time of the photoelectric elements in each separate area.

Abstract: An automatic flash amount control apparatus of camera, which can avoid over-exposure of a subject to be controlled in flash amount even if the subject to be illuminated occupies only a small portion of photo-taking screen, executes photo-metering of a field to be photographed while dividing the field into a plurality of first metering regions without flashing of a flashing device and meters an optical flux emitted by the flashing device and then reflected by the field to be photographed while dividing the flux into a plurality of second metering regions. The apparatus separates the second metering regions into two groups, one of which is to contribute to and the other of which is not to contribute to flash amount control, with correspondence to respective results of metering of the first metering regions.

Abstract: A camera body incorporates an information detecting portion for detecting respective pieces of information on photography with respect to a plurality of areas within a photographing picture and an information selecting portion for selecting specific pieces of information from plural pieces of information. A remote control unit incorporates an area designating portion for designating an arbitrary area among the plurality of areas irrespective of a position of the remote control unit. The information selecting portion is constructed to select the information on the area designated by the area designating portion.
