Abstract
The time required for transmission of image data from an electronic camera to a host computer is shortened. Image data representing the image of a subject imaged in the electronic camera is stored in an image memory. When a preview-image command is applied to the electronic camera from the host computer, the image data that has been stored in the image memory is reduced to 1/8 by eliminating pixels in a thinning-out circuit. The reduced-image data is transmitted to the host computer, where the data is displayed on a display unit as a preview image. A desired area and magnification (resolution) are designated on the preview image and then a get command is applied, whereupon main image data in the designated area and having the designated magnification is transmitted from the electronic camera to the host computer.
