PHOTOGRAPHIC DEVICE WITH ANTI-SHAKE FUNCTION

Abstract

A photographic device, includes a shake detector, a shake mitigator, a first commander, and a shake controller. The shake detector detects a device shake, that is, a shaking of the photographic device. The shake mitigator mitigates the effects of the device shake to reduce an image shake that is a shake of a photographed subject image. The first commander commands the photographic device to photograph the subject image. The shake controller controls the shake mitigator so that the shake mitigator refrains from mitigating the effects of the device shake from the point when the first commander commands the photographic device to photograph the subject image, until the point when photographing the subject image commences.

Claims

1. A photographic device comprising: a shake detector that detects a device shake that is a shake of said photographic device;a shake mitigator that mitigates the effects of said device shake to reduce an image shake that is a shake of a photographed subject image;a first commander that commands to photograph said subject image; anda shake controller that controls said shake mitigator so that said shake mitigator, which is mitigating the effects of said device shake, refrains from mitigating the effects of said device shake from when said first commander commands to photograph said subject image until when photographing said subject image commences.

2. The photographic device according to claim 1, further comprising a luminance measurement device that measures the luminance of a subject, an exposure controller that controls the exposure based on said luminance of said subject, and a second commander that commands said exposure controller to control said exposure, said shake controller controlling said shake mitigator so that said shake mitigator refrains from mitigating the effects of said device shake when said second commander commands said exposure controller to control said exposure.

3. The photographic device according to claim 2, wherein said exposure controller controls said exposure during the period when said shake mitigator refrains from mitigating the effects of said device shake.

4. The photographic device according to claim 1, wherein said shake controller controls said shake mitigator so that said shake mitigator restarts mitigating the effects of said device shake when photographing said subject image commences.

5. The photographic device according to claim 1, further comprising a photographing lens and a focus adjuster that adjusts the focus of said photographing lens, said focus adjuster adjusting the focus of said photographing lens during the period when said shake mitigator refrains from mitigating the effects of said device shake.

6. The photographic device according to claim 1, further comprising a white balance adjuster that adjusts the white balance of said subject image, said white balance adjuster adjusting the white balance of said subject image during the period when said shake mitigator refrains from mitigating the effects of said shake.

7. The photographic device according to claim 1, further comprising an image display that displays said subject image.

8. The photographic device according to claim 1, further comprising at least one of either an exposure controller that controls an exposure based on the luminance of a subject, or a focus adjuster that adjusts the focus of a photographing lens, or a white balance adjuster that adjusts the white balance of said subject image, said shake controller controlling said shake mitigator so that said shake mitigator refrains from mitigating the effects of said device shake from when an operation of said exposure controller or said focus adjuster or said white balance adjuster ends, until when photographing said subject image commences.

9. The photographic device according to claim 1, further comprising at least one of either an exposure controller that controls an exposure based on the luminance of a subject, or a focus adjuster that adjusts the focus of a photographing lens, or a white balance adjuster that adjusts the white balance of said subject image, said exposure controller, or said focus adjuster, or said white balance adjuster operating during the period when said shake mitigator refrains from mitigating the effects of said device shake.
