1. A camera comprising:
an imaging optical system that forms an optical image of a subject to be photographed; an imaging sensor that receives the formed optical image, converts the optical image to an electrical image signal, and outputs the image signal; a camera shake correcting section that corrects shake of the optical image caused by motion of the camera body; a focusing section that performs focus detection in a condition where the camera shake correcting section is operating; a motion detecting section that measures, in the condition where, during a shutter half-press condition, the camera shake correcting section is operating, motion of the subject to be photographed in a predetermined time before a photograph is taken, and detects a speed of the subject from the motion of the subject to be photographed; and a control section that determines an amplification factor and an exposure time during the shutter half-press condition, increases the amplification factor of the image signal and shortens the exposure time when the subject speed detected by the motion detecting section is equal to or higher than a threshold, and takes a photograph by the imaging sensor. |
