Electronic photographing apparatus and electronic photographing apparatus system

An electronic photographing apparatus system comprising an electronic photographing apparatus for converting an optical image of a photographed object in digital image data and a personal computer, comprising:

• a display module disposed in the personal computer, which displays the image data;
• a specification module which specifies a plurality of selected, non-contiguous regions in the optical image displayed at the display module for joined processing of autofocusing;
• a distance measuring module disposed in the electronic photographing apparatus, which measures a distance relevant to any of the selected, non-contiguous regions;
• and
• a control module which controls the distance measuring module to execute a distance measuring operation relevant to any of the selected, non-contiguous regions specified by the specification module, the control module making the display module display module display so as to distinguish a focusable region and an unfocusable region out of the non-contiguous regions specified by the specification module, and
• the control module being capable of releasing a region selected by the specification section when the selected region cannot be appropriately processed with the non-contiguous regions specified by the specification section.

An electronic photographing apparatus system comprising an electronic photographing apparatus and a personal computer, comprising:

• a display device disposed in the personal computer, for displaying an image photographed by the electronic photographing apparatus;
• a pointing device disposed in the personal computer or connected thereto;
• a distance measuring device disposed in the electronic photographing apparatus;
• and
• a control device disposed in the electronic photographing apparatus, the display device displaying so as to distinguish a focusable region and an unfocusable region out of the non-contiguous regions specified by the specification device, and
• the control device being capable of releasing a region selected by the specification section when the selected region cannot be appropriately processed with the non-contiguous regions specified by the specification section, the control device controlling the distance measuring device to be actuated so as to focus an average distance of a plurality of images when the plurality of images are specified from among the images on the display device by the pointing device for joint processing of autofocusing.

A method for measuring a distance of an electronic photographing apparatus system that is composed of an electronic photographing apparatus for converting an optical image of the photographed object into digital image data and a personal computer, comprising:

• photographing an object by the electronic photographing apparatus;
• displaying the object image at a display module disposed in the personal computer;
• specifying a plurality of images from among the images displayed at the display module for joint processing;
• displaying so as to distinguish a focusable region and an unfocusable region out of the non-contiguous regions specified, enabling an operation releasing a specified region when there is an unfocusable region among the specified non-contiguous regions, and causing a distance measuring module disposed in the electronic display module to execute a distance measuring operation relevant to the specified plurality of images for joint autofocusing.
