  • Patent number: 10397466
    Abstract: An extreme value detection section performs a scan operation to detect and store an extreme value of a contrast and a direction of change in the contrast while performing scan driving of a focus lens, based on a direction indicated by a defocus amount. A determination start position calculation section calculates a determination start position corresponding to a position of the focus lens where a determination whether the scan operation is stopped is started, as a position precedent to an in-focus position based on the defocus amount. A control section stops the scan operation if a maximum value is detected during the scan operation before the focus lens reaches the determination start position and it is determined that the contrast decreases as a latest change during the scan operation after the focus lens reaches the determination start position.

  • Patent number: 10389950
    Abstract: An exposure control apparatus prevents exposure from being influenced by false detection and instability of face detection and prevents exposure from being influenced by an object that has cut across in front of a subject. Detection results are obtained by detecting at least one specific region, which is predetermined in advance, in a taken image of the subject. When at least one specific region is detected, one of detection results is selected based on selecting conditions determined in advance to obtain a selected detection result. When it is judged that exposure is not being controlled using the selected detection result, whether or not the selected detection result has changed in a predetermined period is judged. When the selected detection result has not changed, a latest detection result is regarded as the selected detection result, and when the selected detection result has changed, the selected detection result is not changed.
