Abstract:
1. An apparatus comprising: a photo-receiving device configured to receive an image of an object and output signals on the basis of the image; an obtaining device configured to obtain a first evaluation value and a second evaluation value on the basis of the signals from the photo-receiving device, the first evaluation value being obtained by integrating a part of the signals from the photo-receiving device, and the second evaluation value being obtained from peak signals of the part of the signals from the photo-receiving device; and a focus adjusting device configured to perform an operation for focus adjustment using the first evaluation value or the second evaluation value depending upon a peak luminance value and an average luminance value of the received image of the object, wherein, when a peak luminance value is lower than a predetermined peak value, the first evaluation value is used in the operation for focus adjustment, and wherein, when the peak luminance value is higher than the predetermined peak value and the average luminance value is lower than a predetermined average value, the second evaluation value is used in the operation for focus adjustment.
