[0041] Figure 1A is a front perspective view of a digital video camera as an example of an imaging device according to a first embodiment of the present invention, Figure 1B is a rear surface perspective view of a digital video camera as an example of the imaging device according to the first embodiment of the present invention.
[0042] from Figure 1A As can be seen in , the lens unit 2 is connected to the front surface of the camera body 1 . from Figure 1B As can be seen in , a viewfinder (viewfinder) 6 is integrally attached to the rear surface of the camera main body 1 . The lens unit 2 includes a plurality of photographing lenses, and a drive unit. The following will refer to figure 2 The lens unit 2 is described in detail.
[0043] When the release switch 3 is pressed (turned on), the shooting 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 zoom ratio of the taking lens is changed to the tel...

[0079] 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, such as Figure 7 , 8 shown. 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...

[0083] The following will refer to Figure 9 to Figure 12 A third embodiment will be described. 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, Figure 9 It is a block diagram of a digital camera control circuit. Such as Figure 9 As shown, the third embodiment with image 3 The difference of the embodiment is that the correction value memory 118 and the locus correction circuit 121 are omitted, while the distortion correction value memory 171 (distortion information storage unit, image degradation information storage unit) and the image distortion correction circuit 172 are added as constituent elements. It should be noted that in the third embodiment, except image 3 Besides, Figure 1 to Figure 8 Both are commonly referred to by the first and second embodiments. In addition, the third embodiment...
