  • Patent number: 5565917
    Abstract: Each time an area of a distance measurement frame is changed at a position near the center of the lens focused position of a lens unit between the infinite range and the shortest range, a value of a high frequency component which is independent on a contrast is calculated by a system control circuit by a high frequency component in the distance measurement frame which is obtained from a high-pass filter and a luminance component which is obtained from an integrator. The calculated value is compared with a reference value by the system control circuit. When the calculated value is equal to or smaller than the reference value as a result of the comparison, the distance measurement frame is enlarged at a predetermined ratio by the system control circuit.
