Abstract
An image sensing apparatus which hinders execution of vibration cancellation control when an image is sensed with a high-magnification lens, by suppressing vibration cancellation control. Movement of the image sensing apparatus generated purposefully by a user is reflected upon the sensed image without unexpected moving compensation by the vibration cancellation control.
Claims19
A correction apparatus for canceling disturbance of image due to vibrations of an image sensing device having an optical system for zooming operation, comprising:
- vibration detection means for detecting vibration of the image sensing device;
- cancellation means for canceling a disturbance of image due to vibrations of the image sensing device by generating a control signal which corresponds to an output of said vibration detection means;
- zoom position detection means for detecting a zoom position or magnification of the optical system;
- and
- control means for controlling a cancellation operation by said cancellation means in accordance with a detection result of said zoom position detection means.
An image sensing apparatus for canceling a disturbance of image due to vibrations, comprising:
- vibration detection means for detecting vibrations of said image sensing apparatus or an optical system of said image sensing apparatus;
- image vibration cancellation means for optically canceling vibrations of the image through the optical system, in accordance with an output from said vibration detection means;
- image sensing means for sensing an image of which vibrations have been canceled by said image vibration cancellation means;
- mode switching-over means for switching a sensing mode of said image sensing means between an animated-image mode or a still-image mode;
- and
- control means for controlling a correction amount by said image vibration cancellation means when a sensing mode is switched to the still-image mode.
An image sensing apparatus capable of canceling disturbance of image due to vibrations, comprising:
- vibration detection means for detecting vibrations of said image sensing apparatus or an optical system of said image sensing apparatus;
- image vibration cancellation means for optically canceling vibrations of image via the optical system, in accordance with an output from said vibration detection means;
- image sensing means for sensing an image of which vibrations canceled by said image vibration cancellation means;
- mode switching means for switching a sensing mode of said image sensing means between an animated-image mode or a still-image mode;
- and
- control means for, when said sensing mode switching means is switched to a still-image mode, controlling such that a still image outputted by said image sensing means is permitted when a cancellation amount of said image vibration cancellation means is less than a predetermined value.
