[0077] 1A is a front surface perspective view of a digital video camera as an example of an imaging device according to a first embodiment of the present invention, and FIG. 1B is a rear surface of a digital video camera as an example of an imaging device according to a first embodiment of the present invention perspective.
[0078] As can be seen from FIG. 1A , the lens unit 2 is connected to the front surface of the camera body 1 . It can be seen from FIG. 1B that the viewfinder 6 is integrated with the rear surface of the camera body 1 . The lens unit 2 includes a plurality of lenses for imaging, and a drive unit. The lens unit 2 will be described in detail below with reference to FIG. 2 .
[0079] When a release switch 3 is pressed (turned on), the imaging operation is started. The zoom switch 4 includes a T button 4-1 and a W button 4-2. When the T button is pressed, the magnification of the photographing lens is changed to the telescope side. When the W button is pr...

[0115] Even in a video camera having a shake correction unit in which a restoration operation is performed from image data after a still image is captured, the shake correction unit for performing the above-mentioned type of image restoration operation cannot be applied to a through-image display for Observing objects in preparation for still image shooting. Even when this unit is employed, the intended effect cannot be obtained. In order to solve this problem, in the second embodiment, vibration correction that differs with the still image shooting time and the through image display time is performed, as shown in FIGS. 7 , 8 . That is, vibration correction for a moving image (through image) is performed when a through image is displayed, and a different type of vibration correction for a still image is performed when a still image is captured. Also, the through image in the still image mode differs from the through image in the moving image mode in the clipping range of the ...

[0119] A third embodiment will be described below with reference to FIGS. 9 to 12 . In this embodiment, with regard to captured images, after lens distortion correction is performed, electronic vibration correction for still images and electronic vibration correction for moving images are performed. Here, FIG. 9 is a block diagram of a digital camera control circuit. As shown in FIG. 9, the difference between the third embodiment and the embodiment of FIG. 3 is that the correction value memory 118 and the track correction circuit 121 are omitted, and the distortion correction value memory 171 (distortion information storage unit, image degradation information storage unit) is added at the same time. storage unit) and an image distortion correction circuit 172 as constituent elements. It should be noted that in the third embodiment, except for FIG. 3 , FIGS. 1 to 8 are commonly referred to by the first and second embodiments. In addition, the third embodiment differs from the...
