1. A multi-point auto-focus digital camera, comprising: an image-capturing element that receives an image through a photographic lens and that 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 that are preset 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 selecting section that limits selectable focal point detection regions in accordance with a manual operation by a user to regions included in a trimming range from the plurality of focal point detection regions according to the 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 selected, wherein the region selecting section limits the selectable focal point detection regions to include a region in a central portion and at least one region that is included in the trimming range and that is disposed outside the central portion.
