Abstract

The present invention provides an image taking apparatus which determines an exposure from a photometry result in accordance with a program chart and takes an image by exposing an image sensor to light with the determined exposure. The image taking apparatus includes a motion detection device which detects motion of an image taken by the image sensor on the basis of images continuously taken by the image sensor, and a program chart switching device which switches between program charts depending on a magnitude of motion detected by the motion detection device such that a shutter speed becomes faster with respect to a single photometry result.

Claims

1. An image taking apparatus which determines an exposure from a photometry result in accordance with a program chart and takes an image by exposing an image sensor to light with the determined exposure, comprising:

a motion detection device which detects motion of an image taken by the image sensor on the basis of images continuously taken by the image sensor; and

a program chart switching device which switches between program charts depending on a magnitude of motion detected by the motion detection device such that a shutter speed becomes faster with respect to a single photometry result.

2. The image taking apparatus according to claim 1, wherein the motion detection device detects the motion of the image taken by the image sensor on the basis of a difference between an image of a current frame and an image of an immediately preceding frame taken by the image sensor.

3. The image taking apparatus according to claim 1, wherein a plurality of program charts to be selected depending on a magnitude of motion detected by the motion detection device are prepared.

4. The image taking apparatus according to claim 2, wherein a plurality of program charts to be selected depending on a magnitude of motion detected by the motion detection device are prepared.
