Abstract
A camera for recording an image captured using image-capturing element in a recording medium is provided with a focal point detection device for detecting a focal point adjustment state of a photographic lens in each focal point detection region of a plurality of focal point detection regions set inside an photographic field. When electronic zoom shooting is carried out, part of an imaged picture is trimmed and an image for recording in the recording medium is created. For a plurality of focal point detection regions the focal point detection regions are changed according to the trimming range of the imaged picture. Focal point adjustment of the photographic lens is carried out based on focal point detection results for focal point detection regions that have been changed.
Claims12
A multi-point auto-focus digital camera, comprising:
- an image-capturing element that receives an image through a photographic lens and outputs an image signal corresponding to the image;
- a focal point detection device that detects a focal point adjustment state of the photographic lens in each focal point detection region of a plurality of focal point detection regions set inside a photographic field based on the image signal outputted from the image-capturing element;
- an image trimming section that trims part of the image signal to create a trimmed image signal;
- a display device that displays the image signal outputted from the image-capturing element and the trimmed image signal created by the image trimming section;
- a region changing section that changes the plurality of focal point detection regions according to a trimming range of the trimmed image signal;
- and
- a focal point adjustment device that carries out focal point adjustment of the photographic lens based on focal point detection results for the focal point detection regions that have been changed,
- wherein the region changing section selects focal point detection regions according to the trimming range of the trimmed image signal.
