摘要： A device includes a photometry element for photometrically measuring object light while dividing the object light into a plurality of color components, and an exposure controller for calculating an exposure control value on the basis of a plurality of photometry outputs corresponding to the color components from the photometry element. In the device, the photometry element divides object light into a plurality of color components, e.g., R, G, and B three primary colors, and performs level detection in units of color components. The exposure controller preferably determines, as an exposure control value, a color component of a maximum level of the photometry outputs corresponding to the color components which are measured by the photometry element. Exposure control is executed by calculating an aperture value, a shutter speed, and the like on the basis of the determined exposure control value.

摘要： An optical low-pass filter is built with circular phase components consisting of randomly distributed convex and concave surfaces. The area of the phase components is structured to cover 1/2 the entire surface area of the low-pass filter. Moreover, the phase components are set to a height such that the phase difference between the light passing through the phase components and the other areas of the filter is 1/2 its wavelength. The optical low-pass filter is installed in front of the photometric optical system. It is therefore possible to precisely measure light regardless of incidence of light from the photographic subject even when using photometric sensors that have been divided into multiple units.

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.
