PHOTOGRAPHIC DEVICE WITH ANTI-SHAKE FUNCTION

Abstract

A photographic device includes a shake detector, a shake mitigator, a shake controller, and a shutter speed setter. The shake detector detects a shake of the photographic device. The shake mitigator mitigates the shake to reduce the effect of the shake on a photographed subject image. The shake controller controls the shake mitigator. The shutter speed setter sets a shutter speed of the photographic device for photographing the subject image. The shake controller controls the shake mitigator so that the shake mitigator mitigates the shake only when a shutter speed that is lower than the maximum shutter speed is set.

Claims

1. A photographic device comprising: a shake detector that detects a shake of said photographic device;a shake mitigator that mitigates said shake to reduce the effect of said shake on a photographed subject image;a shake controller that controls said shake mitigator; anda shutter speed setter that sets a shutter speed of said photographic device for photographing said subject image;said shake controller controlling said shake mitigator so that said shake mitigator mitigates said shake only when a shutter speed that is lower than a maximum shutter speed is set.

2. The photographic device according to claim 1, further comprising a zoom lens and a maximum shutter speed setter that sets said maximum shutter speed in accordance with a focal distance of said zoom lens.

3. The photographic device according to claim 2, wherein the larger the said focal distance of said zoom lens, the higher the said maximum shutter speed set by said maximum shutter speed setter.

4. The photographic device according to claim 1, further comprising an indicator that indicates whether said shake mitigator mitigates said shake or not.

5. The photographic device according to claim 4, wherein said indicator further indicates said shutter speed that is set by said shutter speed setter, and whether said shake mitigator mitigates said shake or not, at the same time.

6. The photographic device according to claim 4, wherein said indicator further indicates said subject image, and whether or not said shake mitigator mitigates said shake, at the same time.

7. The photographic device according to claim 4, further comprising an indication commander that commands said indicator to indicate whether said shake mitigator mitigates said shake or not, said indicator indicating whether said shake mitigator mitigates said shake or not based on the first operation of said indication commander, said subject image being photographed based on the second operation of said indication commander.

8. The photographic device according to claim 4, further comprising a shake mitigation commander that commands said shake mitigator to mitigate said shake, said indicator indicating a warning message when said shake mitigator is not mitigating said shake, regardless of the command by said shake mitigation commander.

9. The photographic device according to claim 1, further comprising an imaging device that receives light from a subject, wherein said shake mitigator moves said imaging device so that the effect of said shake on a photographed subject image is reduced.
