[0034]

[Table 1]

FIG. 2 and FIG. 3 are explanatory diagrams for explaining a case of correcting image shake between frames (images).
In particular, FIG. 2 is a diagram showing a case where the shake between frames is not corrected,
FIG. 3 is a diagram showing a case where the shake between frames is corrected.

As shown in FIG. 2, when the shake between frames is not corrected, the position of the subject image shifts for each frame with the shake. On the other hand, as shown in FIG. 3, when the correction between frames is performed, the position of the subject image becomes a correct position without being affected by the shake.

FIGS. 4 and 5 are explanatory diagrams for explaining the case where the shake within one frame (image) is corrected. In particular, FIG. 4 is a diagram showing the case where the shake is not corrected within the frame. FIG. 5 is a diagram showing a case where the shake is corrected in the frame.

As shown in FIG. 4, when the shake in the frame is not corrected, the position of the subject image in the frame shifts with the shake. On the other hand, as shown in FIG. 5, when the shake is corrected in the frame, the flow of the subject image can be corrected without being affected by the shake.

FIGS. 6 and 7 are explanatory diagrams for explaining the shake between frames and within a frame. In particular, FIG. 6 is a diagram for explaining a case where the shake between frames and within a frame is not corrected. 7
FIG. 8 is a diagram for explaining a case where the shake between frames is corrected.

As shown in FIG. 6, when the shake between frames and within a frame is not corrected, the position of the subject image between the frames and within the frame is shifted with the shake. On the other hand, as shown in FIG. 7, when the shake between the frames is corrected, the shake between the frames can be corrected, but the shake in the frame cannot be corrected.

Therefore, the first shake correcting means can correct the shift between frames, but cannot correct the image current during one-frame exposure. If the video image is printed out with the video image still, the image becomes a camera shake image. In this case, in order to prevent the image quality from deteriorating due to camera shake, it is necessary to make corrections in frames even when shooting moving images.

FIGS. 8 to 11 are explanatory diagrams for explaining the effective range of the CCD 23 when displaying an image on the display unit (monitor) 6. FIG. FIG. 8 shows C in the case of displaying on the display unit 6.
FIG. 9 is a view showing an effective range of the CD 23, FIG. 9 is a view showing an example of a shake in the effective shooting range of the CCD 23, FIG. 10 is a view showing an example of an image displayed on the display unit, and FIG. FIG. 6 is a diagram showing an example in which is displayed on a display unit.

In the present embodiment, as shown in FIG. 8, a range narrower than the actual effective imaging range (a) of the CCD 23 is set as the display range (b) of the monitor. Thus, there is no uncomfortable feeling even if the screen is cut out by performing the shake correction by the CCD drive control method. As a specific example, even if the image shakes during the exposure as shown in FIG. 9, for example, the image is displayed on the display unit 6 as shown in FIG. On the other hand, when the effective range of the image sensor is displayed on the display unit 6, if a shake correction is performed by the CCD driving method, a portion having no data appears on the monitor as shown in FIG.

Next, a camera shake correction operation of the digital camera according to the first embodiment will be described with reference to FIGS. FIG. 12 is a flowchart for explaining an example (part 1) of a camera shake correction operation of the digital camera.

The first shake correction unit 31b corrects the shake between images (between frames) (step S111). Then, the image whose shake has been corrected is recorded in the recording storage unit 112 (step S11).
2). Subsequently, it is determined whether or not the imaging has been completed (step S113). If the imaging has not been completed, the process returns to step S108, while if the imaging has been completed, the process ends.

In this case, the image stabilization means (the first image stabilization means or the second image stabilization means) is switched in accordance with the condition (1). It is possible to obtain a great camera shake correction effect.

FIG. 13 is a flowchart for explaining an example (part 2) of a camera shake correction operation of the digital camera. The shake correction operation shown in FIG. 13 indicates a case where the means for performing shake correction is switched when the monitoring (display mode) is switched to the shooting operation state (such as when a release key is pressed).

While the first camera shake correction means (first shake correction mode) is selected, if the recording mode is detected, the second camera shake correction means (second shake correction mode) is selected (step S121). .

If the first shake correction mode has been selected, the flow shifts to step S122, where exposure of the CCD 23 is started to capture an image. Then, the first shake detecting unit 31a detects the shake of the image based on the read image (Step S123), and the first shake correcting unit 31b.
Performs correction of shake between images (between frames) (step S1).
24). Then, the image whose shake has been corrected is displayed on the display unit 6 (step S125). Subsequently, it is determined whether or not the photographing is completed (step S126). If the photographing is not completed, the process returns to step S122. If the photographing is completed, the process is terminated.

On the other hand, when the second shake correction mode is selected in step S121, in step S127, the second shake detection unit 7a detects the shake, and the second shake correction control unit 7b sets the shake correction The unit 24 is driven to correct the shake (step S128). The shake detection and shake correction are performed while focusing or exposure is being performed.
Then, the captured image is read (step S12).
9), and record it in the record storage unit 33 (step S13)
0). Then, it is determined whether or not the photographing is completed (step S131). If the photographing is completed, the process is terminated. If the photographing is not completed, step S1 is performed.
Move to 20.

As described above, according to the above operation example, the camera shake correction is performed by the first camera shake correction means in the display mode, while the camera shake correction is performed by the second camera shake correction means in the recording mode. In addition, it is possible to perform camera shake correction suitable for each mode. Further, in the display mode, the camera shake correction is performed by the first camera shake correction means, so that it is possible to suppress energy consumption due to the camera shake correction.
