Abstract:
1. An electronic camera, comprising: an imager having an imaging surface that captures a scene through a focus lens and outputting an electronic image representing the scene in a designated cycle; a first changer which changes a distance from the focus lens to the imaging surface; a first adjustor which adjusts a length of the designated cycle to a length being different depending on an illuminance of the scene, in association with the change process of said first changer; a first specifier which specifies a distance range including a focal point based on the electronic image outputted from said imager, in parallel with the change process of said first changer; a second changer which changes the distance from the focus lens to the imaging surface in the distance range specified by said first specifier; a second adjustor which adjusts the length of the designated cycle to a length being different depending on a contrast of the scene during the change process of said second changer such that a frame rate that corresponds to the length of the designated cycle is set to a high frame rate if the contrast is high and a low frame rate if the contrast is low; and a second specifier which specifies a distance equivalent to the focal point based on the electronic image outputted from said imager, in parallel with the change process of said second changer.
