摘要： The image capturing apparatus can perform image capturing at a high frame rate higher than a frame rate used for displaying a moving image. In image capturing with flashlight in the image capturing apparatus, the high frame rate is set and three images are successively captured while increasing the light emission amount of the flashlight in order. A region in the lower portion of the image captured first, a region in the center portion of the image captured second, and a region in the upper portion of the image captured third, the exposure level being proper in each of these regions, are extracted and combined. As a result, a high-quality synthetic image in which exposure is proper from the front side to the deep side in image capturing in a room can be generated.

摘要： The image capturing apparatus can perform an image capturing operation at a frame rate which is three times as high as a frame rate for displaying a moving image. At the time of moving image capturing, an operation of capturing three kinds of frame images is repeated while changing a focus condition in three levels of, for example, a focus backward of an infocus position on a main subject, a focus in the infocus position, and a focus forward of the infocus position. With this operation, a moving image constructed by images in which focus is achieved on a backward car, a moving image constructed by images in which focus is achieved on a car in the center, and a moving image constructed by images in which focus is achieved on a forward car can be recorded. As a result, moving images with three kinds of different image capturing conditions can be easily captured by a single image capturing operation.

摘要： The present invention provides a digital camera having an automatic tracking AF function, with shortened time required to re-achieve focusing after focusing becomes unmaintainable, which does not make the user feel strange. In a pattern drive AF control (normal control state), the digital camera performs pattern driving of finding an infocus lens position at the present time point around the latest infocus lens position while performing automatic tracking control of changing the position of the focus area so as to trace the movement of a main subject. When the digital camera loses the track of the subject during execution of the pattern drive AF control (normal control state), until at least predetermined time elapses (subject loss time point), pattern drive AF control (extended control state) is continued.
