Problems solved by technology

[0007] According to cited Patent Document 1, since the operating range of the correction means is a linear integral output and this linear integral output represents the output obtained when a constant integral coefficient is specified regardless of the size of the remaining area, the linear integral is limited while it reaches the correction end output, therefore, the disadvantage is that the picture will suddenly reach the trouble of correcting the end

Embodiment Construction

[0027] An image pickup apparatus and a camera shake correction method according to embodiments of the present invention will now be described with reference to the accompanying drawings.

[0028] [System Configuration]

[0029] Attached figure 1 A camera shake correction device used with the image pickup device applied to the embodiment of the present invention is shown in the form of a block diagram.

[0030] Such as figure 1 As shown, the image pickup apparatus 1 outputs an image of the entire area (effective area) on the image pickup surface in the form of an analog signal. An analog-to-digital converter (ADC) 2 converts an analog signal output from the image pickup device 1 into a digital signal. The correction circuit 3 extracts an area (high efficiency area) from a part of the effective area based on the correction amount output from the controller 5 . The camera shake detection unit 4 detects camera shake applied to the image pickup device. The camera shake detecti...

Abstract

In an image pickup device according to the present invention, a controller includes a surplus area calculation unit to detect a surplus area for use in correcting camera shake based upon a size of an effective area on an image pickup surface and a size of an efficient area extracted in response to camera shake. Thus, this image pickup device can prevent a troublesome aspect in which camera shake correction reaches the correction end from occurring even when large camera shake which is beyond the surplus area occurs.

Description

technical field [0001] The present invention relates to an image pickup apparatus and a camera shake correction method for realizing camera shake correction on an image signal. Background technique [0002] Cited Patent Document 1 has hitherto disclosed a camera shake correction apparatus comprising: tilt and yaw amount detection means for detecting the amount of an image tilt (pitch) or yaw (yaw) due to vibration of a camera body; a correction signal generating means for correcting a tilt or a deflection of an image based on a detection output from the tilt and deflection amount detecting means, the correction signal generating means having a correction range set to be freely variable; a correction means which is operated to correcting the tilt and deflection of the image in response to a correction signal generated from the correction signal generating means; operating range detecting means for detecting the operating range of the correcting means; and correction range set...
