Abstract: An generation section generates a first display image based on an image signal output from an image pick-up device including first and second pixel groups on which respective images are formed by a pupil-divided subject-image, and generates a second display image for use in focus verification from first and second images based on an image signal output from the first and second pixel groups. A display controller performs control to display the first display image on a display section, and to display the second display image on the display section within a display region of the first display image. An automatic focus section, in cases in which a predetermined instruction has been input, performs automatic focusing in a focus region having at least a portion that overlaps with at least a portion of a display region of the second display image.

Abstract: It is intended to provide an imaging apparatus that enables proper exposure of phase difference detection pixels and thereby makes it possible to perform phase difference autofocusing with high accuracy. A system control unit 11 selects phase difference detection pixels from phase difference detection pixels 51R and 51L existing in a selected phase difference detection area 52 according to a position of the selected phase difference detection area 52 in a row direction X, and determines exposure conditions based on output signals of the selected phase difference detection pixels. A defocus amount calculation unit 19 calculates a defocus amount using output signals of the phase difference detection pixels 51R and 51L existing in the selected phase difference detection area 52 that are part of a shot image signal produced by shooting that is performed by an imaging device 5 under the exposure conditions determined by the exposure determining unit 11.

Abstract: A digital camera 10 includes an imaging device 21a, a finder device 15, a phase difference information analyzing portion 71 and a control portion 32. In the finder device 15, an image in which an OVF optical image formed by an objective optical system 65 and an image displayed on a display portion 61 are superimposed on each other can be observed through an eyepiece window 17. The phase difference information analyzing portion 71 determines a focus region and a non-focus region in a photographic subject imaged by the imaging device 21a. The control portion 32 makes control to display an image Eg for highlighting the focus region E in the OVF optical image on the display portion 61 in the state in which the OVF optical image can be observed through the eyepiece window 17.
