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： An automatic focusing apparatus repetitively detects a defocus amount of a photographing lens, discriminates whether or not an object is moving, and calculates a pursuit correction amount for a moving object on the basis of present and previous defocus amounts. When a non-moving object is discriminated, a drive amount of the lens is calculated on the basis of the present defocus amount, and when a moving object is discriminated the drive amount is calculated on the basis of a pursuit drive amount as a sum of the present defocus amount and the pursuit correction amount. A pursuit enable/disable determining device determines whether the drive amount is calculated on the basis of the discrimination result or on the basis of the present defocus amount. When a drive direction of the lens is reversed, the pursuit enable/disable determining device causes calculation of the drive amount of the photographing lens on the basis of the present defocus amount for driving the lens in a predetermined number of drive operations after the reversal.
