1. An image pickup apparatus comprising:
an image pickup device arranged such that a light receiving surface is orthogonal to an optical axis of an image pickup lens, the image pickup device acquiring primary image data at each predetermined frame period; a focal length detection unit that acquires a focal length of the image pickup lens in synchronization with the frame period; an input device that receives input of correction angles including two values including a first angle that is an angle formed in a pitch direction relative to the light receiving surface and a second angle that is an angle formed in a yaw direction relative to the light receiving surface; an image processing unit that uses a value of the focal length and the values of the correction angles in synchronization with the frame period to generate secondary image data obtained by applying a modification process of projecting the primary image data onto a plane forming the first angle in the pitch direction relative to the light receiving surface and forming the second angle in the yaw direction relative to the light receiving surface; an image display device that displays an image based on the secondary image data in synchronization with the frame period; and an AF control unit that performs control of changing a focus distance of the image pickup lens, wherein the input device receives input of designating a position of an AF area in the secondary image data displayed on the image display device, the image processing unit executes a conversion process of projecting the position of the AF area in the secondary image data onto a plane including the primary image data, and the AF control unit changes the focus distance of the image pickup lens to put the image pickup lens into a focused state at a position on the light receiving surface corresponding to the AF area projected onto the plane including the primary image data. |
