摘要： A focusing control device that can keep a moving subject in focus and can prevent significant defocusing of a low contrast subject or under a low-light intensity condition during continuous shooting. The focusing control device determines whether an in-focus position of a focusing lens can be obtained, predicts an in-focus position for the current exposure operation based on an in-focus position for the previous exposure operation when continuous main exposure operation is performed for shooting, and determines whether prediction of an in-focus position is possible. When prediction of an in-focus position for the current exposure operation is determined to be not possible, the focusing control device performs a scan operation to obtain an in-focus position based on an in-focus position of the previous exposure operation where obtaining of an in-focus position of the focusing lens was determined to be possible.

摘要： The focus control apparatus performs focus control of the interchangeable lens by using information obtained through detection of a focus state of an interchangeable lens and a correction value corresponding to the interchangeable lens. The interchangeable lens is a first interchangeable lens holding unique correction value calculation data used to calculate the correction value, or a second interchangeable lens not holding the correction value calculation data. The focus control apparatus includes a first memory storing values for calculating the correction value corresponding to the second interchangeable lens. A controller calculates the correction value by using the correction value calculated based on the values read from the first memory when the second interchangeable lens is attached to the image capturing apparatus, and by using the correction value calculation data acquired from the first interchangeable lens when the first interchangeable lens is attached to the image capturing apparatus.

摘要： An automatic focal adjustment apparatus capable of focusing at a distance appropriate for an object at infinity, and a method of controlling the automatic focal adjustment apparatus, are disclosed. The automatic focal adjustment apparatus detects an in-focus position of a focus lens based on an AF evaluation value generated from an image signal. Also, the automatic focal adjustment apparatus moves the focus lens to the detected in-focus position when the detected in-focus position is within a predetermined range from a reference position determined in advance corresponding to an object at a infinity distance.

摘要： An exposure control apparatus which is capable of making a backlight judgment with accuracy using image data on a main subject and image data on a photographer and controlling exposure according to the judgment result. First image data is generated according to a main subject image formed by light from the main subject via a first shooting optical system, and second image data is generated according to a photographer image formed by light from a photographer via a second shooting optical system. First luminance information is obtained based on the first image data, and second luminance information is obtained based on the second image data. According to the first luminance information and the second luminance information, whether or not the main subject is in backlight scene is judged, and based on a result of the judgment, exposure for the main subject is controlled.
