Abstract: A digital camera capable of compensating a portion of a captured image with another image without putting a squeeze on storage capacity. The digital camera has a plurality of image-capturing systems capable of essentially simultaneously capturing images of a single subject at mutually-different angles of view. Information about relevant image data which are items of the other simultaneously-captured image data is imparted as relevant information to at least one item of image data among items of image data captured by the plurality of image-capturing systems. The image data imparted with the relevant information and the relevant image data captured simultaneously with the image data are stored as separate items of data in user memory which serves as storage means.

Abstract: The present invention provides a digital camera which has a plurality of image capturing optical systems and quickly performs automatic focusing. A digital camera includes a first image capturing optical system formed from a lens 2 and a first image sensor, and a second image capturing optical system formed from a lens 3 and a second image sensor. An image processor detects a phase difference between an image of a single subject formed on the first image sensor and an image of the same formed on the second image sensor, in order to perform phase-difference AF. Since the lenses 2, 3 have different focal lengths, the image processor executes correlation operation after having performed conversion processing for causing a scaling factor of the image formed by the first image sensor to coincide with that of the image formed by the second image sensor, to thus detect a phase difference.

Abstract: In a digital camera, control operations, such as an AF (automatic focusing) operation which is performed immediately after zooming or panning of the camera, can be performed quickly in an appropriate manner. When a zoom lens 3 is driven to zoom “up”(“in”), a control processor and timing generator 40 uses, of imaging conditions data, such as distance measuring data and photometering data, which are obtained at a wide viewing angle before zooming up, a portion of the imaging conditions data corresponding to a “tele” (telephoto) viewing angle after zooming up, to thereby perform AF, AE, and/or AWB operations after zooming up. When the user pans the camera to shift the viewing angle out of the range of the original wide viewing angle, the data of an area of the image plane of the wide viewing angle closest to the image plane of a new post-panning viewing angle is reused.
