摘要： A photometric apparatus of a camera for carrying out a multi-segmented photometry by receiving object light reflected at a film or the shutter, includes a plurality of photometric elements which are disposed at positions to respectively receive reflected light from the film or the shutter. The elements are segmented in accordance with each of regions segmenting the object field, corresponding to regions of the film or the shutter, and are arranged in parallel in a predetermined direction within a mirror box so as to respectively receive light reflected with diffusion angles less than a predetermined angle from respective reflection regions of the film or the shutter. Photometric lenses are respectively positioned between the reflection regions and the photometric elements, corresponding to the photometric elements, so as to respectively direct the object light reflected at the reflection regions to the plurality of photometric elements, and are arranged in parallel so as to restrict incidence of reflected light on the photometric elements from other reflection regions.

摘要： Disclosed is an exposure control device for an automatic illumination adjustment controlled type camera in which flashing of a flash apparatus built in a camera body is automatically stopped. The exposure control device includes an exposure value calculating unit for calculating an exposure value on the basis of photometering of an object before an exposure operation is started, and an exposure value compensating unit for correcting the exposure value calculated by the exposure value calculating unit to a value which assures overexposure when a picture is taken using a flash. Also disclosed is a TTL automatic illumination adjusting type camera which has an illumination adjusting unit for receiving light coming from a flash, reflected by an object and incident through a lens, and for stopping the flashing of the flash apparatus when the amount of light received reaches an illumination adjusting level. The camera is capable of employing a plurality of electronic flash apparatuses having different flashing characteristics. The camera includes a recognizing unit for outputting a recognition signal when it recognizes the type of the electronic flash apparatus used, and a level setting device for setting the illumination adjusting level on the basis of the recognition signal, such that an object having the same luminance is illuminated by the same amount of light regardless of which one of the electronic flash apparatuses is used.

摘要： A camera is adapted so that a light emission level of a flashing apparatus is automatically corrected through the comparison of the control value with the appropriate exposure for the constant illumination (background illumination). As a result, an appropriate exposure can be given for the principal object, such as a person, even when the exposure for the constant illumination is outside the exposure control range or is intentionally decreased or increased.
