Digital camera
This invention includes an imaging device that photographs a subject, a display device that has a display screen displaying image data photographed by the imaging device, a zoom device that varies the display screen, an extraction device that extracts a predetermined feature portion from image data photographed by the imaging device, a directive device that directs the display device so as to display a predetermined feature portion extracted by the extraction device in a predetermined form, and a controller that controls the directive device so as not to direct a display on the display device in accordance with the varying magnification of the zoom device. Namely, an icon of the extraction result is not displayed while the zoom is in action, so that it can avoid an inappropriate display in which the icon display does not correspond to a photographed subject due to the subject's quick movement or a sudden change in its size within a picture frame.
1. A digital camera comprising:
an imaging device that photographs a subject;
an extraction device that extracts a predetermined feature portion within image data output from the imaging device;
a judging device that judges brightness of the subject; and
a selecting device that selects a first extraction area of an image when the brightness of the subject is above a threshold value, and selects a second extraction area of the image when the brightness of the subject is below the threshold value, the second extraction area being smaller than the first extraction area wherein the extraction device extracts the predetermined feature portion from the selected extraction area of the image of the image data in accordance with the brightness of the subject judged by the judging device.
2. The digital camera as set forth in claim 1 , further comprising:
a focus device that performs a focusing operation with respect to the subject, using the image data output from the imaging device; and
a focus control device that determines a position of an AF area, based on the predetermined feature portion extracted by the extraction device, and controls the focus device so as to perform the focusing operation.
