Even with an interline CCD, if an electronic shutter is used, the main image can be taken at an interval of 30 frames / second, so that the sub-image can be taken at several steps faster than this.
At this time, the shutter speed is set at least to the camera shake limit, but set as fast as possible within a range where an appropriate gain can be obtained.

On the other hand, when the shutter speed is increased, the gain is reduced (for example, when the shutter speed is doubled, the gain is reduced by half). Therefore, at the timing shown in FIG. Or
Either switch the optical filter 4 to the one with the smaller effect, increase the gain of the amplifier 7, synchronize the flash 8 (see FL in FIG. 2A), or increase the shutter speed by using these together. (Refer to the point where the sub-exposure time ts in FIG. 2A is ts <the main exposure time tr.) An appropriate gain of the sub-image is obtained.

Then, as shown in FIG. 3A, the obtained sub-image SVi (i = 1,..., N) and the main image MVi (i =
1,..., N) (step S in FIG. 23).
4), after photographing,
Pixel blurring due to blur caused by a slow shutter speed during main image shooting is corrected (see step S5 in FIG. 23). When an image of a landscape, a moving object, or the like is captured at a shutter speed higher than usual (see steps S1 and S2 in FIG. 23), only the main image is captured (see step S6 in FIG. 23), and needless to say, this is recorded. These operations are repeated until the image information recording device 13 becomes full (see step S7 in FIG. 23) (see step S8 in FIG. 23). FIG. 3 is a conceptual diagram. In the actual image information recording device 13, the main image and the sub-image may be recorded on different recording media or different areas on the same recording medium. What is necessary is just to be able to correspond.

Further, as shown in FIG. 3B, the sub-image SVi
(I = 1,..., N) instead of recording the main image MVi
By recording processing intermediate information SVSi (i = 1,..., N) such as a contour image calculated from a sub-image together with (i = 1,..., N) (steps S10 and S11 in FIG.
When performing the shake correction calculation after the shooting (see step S12 in FIG. 24), the calculation time can be shortened, so that the shot main image can be corrected, reproduced and displayed. Become. In other words, the processing time of the shake correction calculation can be divided between the time of shooting and the time of display, and the waiting time until display is reduced, so that application to moving images such as continuous imaging recording and playback display is possible. . further,
As shown in FIG. 3C, the main image is corrected by performing the shake correction operation at high speed (see step S13 in FIG. 25), and only the corrected main image RMVi (i = 1,..., N) is recorded. Thus (see step S14 in FIG. 25), the consumed capacity of the image information recording device 13 can be reduced.

As described above, according to the first embodiment, immediately before or immediately after the main image is captured, the sub-image is captured at a shutter speed faster than that of the main image so as to prevent blurring. The blur correction of the main image is performed by using the contour information and the like obtained by calculating this, so that a movable optical system that is expensive and has a severe requirement for optical accuracy when the number of CCD pixels increases is used. This makes it possible to realize the shake correction without any problem, and to provide a shake correction function to a portable, inexpensive, small and lightweight digital still camera or digital video camera. In addition, there can be obtained one that can also perform correction for a shake exceeding the limit of motion detection. Note that the image may be corrected by using the sub-image itself if the arithmetic unit has enough computing power.

Claim 39, Claim 40, Claim 41, Claim 42, Claim 44, Claim 45, Claim 46, Claim 50, Claim 51, Claim 56, Claim 57, Claim 58, Claim 59 and Claims 71, 72, 73, 74, 76, 77, 78, 80, 83, 88, 89, and 89. A second embodiment of the present invention described in claim 90 and claim 91 will be described with reference to FIGS. 4, 5, 6, 26, 27, and 28. FIG. Note that the configuration is the same as that of the first embodiment except that the blurred image correction program executed by the microcomputer of the shutter control circuit is changed to the one shown by the flowcharts of FIGS. The description is omitted.

As in the first embodiment, a sub-image is photographed at a higher shutter speed immediately before or immediately after the main image is photographed. At a timing as shown in FIG. 4A, a plurality of sub-images are taken immediately before or immediately after one main image (see step S15 in FIG. 26).
As shown in (a), the image information is recorded as a pair in the image information recording device 12 (see step S16 in FIG. 26). FIG.
As shown in (a), the recorded image is a sub-image SV1.
1, the sub-image SV12 and the main image MV1, but the sub-image S
By comparing V11 with the sub-image SV12, FIG.
As shown in (b), the motion vector V1 indicating the direction and magnitude of the blur is known (see step S17 in FIG. 26).
Therefore, in the main image, since the pixels are mixed in this direction, these separation operations are performed based on the motion vector V1 (see step S18 in FIG. 26) to correct the blur. Further, by setting the imaging interval between the sub-images SV11 and SV12 to be equal to the exposure time of the main image, the motion vector V2 of the main image can be immediately obtained from the motion vector V1 of the sub-image.

Next, what is recorded together with the main image MVi is not a plurality of sub-images SVij (j = 1, 2,...)
When the blur parameter PMi is used, the magnitude and direction (motion vector) of the blur are immediately calculated from the plurality of captured sub-images (see step S19 in FIG. 27), and these are used as the blur parameters as shown in FIG. 6B. (Fig. 27)
Step S20). Thus, the consumption of the recording unit in the image information recording device 12 can be reduced, and the main image can be corrected based on the consumption (step S2 in FIG. 27).
1). In addition, real-time processing is possible if there is a processing capability that allows display while performing shake correction calculation using this parameter during display, and the amount of calculation per unit time can be reduced even when applied to a moving image.

Further, while the blur of the main image is corrected using this parameter (see step S22 in FIG. 28), only the corrected main image RMVi is recorded (see step S23 in FIG. 28). As shown in (c), the consumption of the recording unit can be further reduced, and the blur-corrected image can be recorded while being monitored in real time.

As described above, even when a plurality of sub-images are picked up at a high shutter speed, the gain of the sub-images is reduced as in the first embodiment. Therefore, the mechanical aperture 2 shown in FIG. Open more or optical filter 4
By switching to the smaller effect, increasing the gain of the amplifier 7, emitting the strobe light 8, or using them together, it is possible to obtain an appropriate gain for the sub-image with a higher shutter speed.

As described above, according to the second embodiment, immediately before or immediately after the main image is captured, a plurality of sub-images are captured at a faster shutter speed than the main image is captured so as not to cause blurring. However, since the main image is shake-corrected by using the sub-image or a shake parameter obtained by calculating the sub-image, the demand for the optical accuracy becomes strict when the number of pixels of the CCD is increased. Blur correction can be realized without using a movable optical system, and a blur correction function can be provided to a portable, inexpensive, small and lightweight digital still camera or digital video camera. In addition, there can be obtained one that can also perform correction for a shake exceeding the limit of motion detection.

The main image may be corrected using the outlines of a plurality of sub-images. If the processing capacity of the arithmetic unit has room, the main image may be corrected using the plurality of sub-images themselves. May be. Furthermore, the imaging interval and the number of captured images of the sub image may be changed according to the exposure time of the main image, and the blur parameter may be calculated accurately.

(Embodiment 3) Next, claim 7, claim 8, claim 9, claim 11, claim 12, claim 13, claim 14, claim 18, and claim 19 of the present invention. , Claim 24, Claim 25, Claim 26, Claim 27, and
Claim 39, Claim 40, Claim 41, Claim 43, Claim 44, Claim 45, Claim 46, Claim 50, Claim 51, Claim 56, Claim 57, Claim 58, Claim 59 and Claims 71, 72, 73, 75, 76, 77, 78, 82, 83, 88, 89, and 89. Embodiment 3 Embodiment 90 of the present invention described in claim 90 and claim 91 will be described with reference to FIGS. 7, 29, 30, and 31. FIG. In addition, regarding the configuration, the blurred image correction program executed by the microcomputer of the shutter control circuit corresponds to FIG.
9 to 31 are the same as those in the first embodiment except that they are changed to those shown by the flow charts in FIGS.

In the third embodiment, a plurality of sub-images are photographed by increasing the shutter speed in the same manner as in the second embodiment. However, as shown in FIG. At least one image is taken at a time (FIG. 2).
9 step S24). Then, the main image and the sub image are recorded (see step S16 in FIG. 29), a motion vector is detected (see step S17 in FIG. 29), and the main image is corrected (see step S18 in FIG. 29).

As in the third embodiment, using two sub-images SVi2 and SVi3 photographed immediately before and immediately after the photographing of the main image, parameters corresponding to the direction and magnitude of the blur of the main image are determined. The calculation accuracy is better than the calculation using two sub-images SVi1 and SVi2 taken immediately before the main image MVi (i = 1, 2,...) As in the second embodiment. Thus, the image quality of the corrected main image is improved. This is because if the blur that occurred while capturing the main image changed direction from the blur that occurred while capturing multiple sub-images immediately before capturing the main image, This is based on the fact that the prediction performed based on the blur occurring during the imaging improves the prediction accuracy.

Instead of recording the main image and the sub-image, a blur parameter is detected (see step S19 in FIG. 30), and this and the main image are recorded (step S19 in FIG. 30).
The main image is corrected (see step S2 in FIG. 30).
1), the main image is corrected (see step S22 in FIG. 31), and only the corrected main image is recorded (see step S23 in FIG. 31), thereby reducing the consumption of the recording unit of the image information recording device 13. You may make it reduce.

As described above, according to the third embodiment, at least one of the images immediately before and immediately after the main image is captured, and a plurality of shutter images are recorded at a faster shutter speed than when the main image is captured so as not to cause blurring. Since the sub-image is imaged and the main image is corrected using the sub-image or the blur parameter obtained by calculating the sub-image, the optical image is expensive and when the number of CCD pixels increases, the optical Shake correction can be realized without using a movable optical system that requires stricter accuracy, and it is possible to provide a shake correction function to a portable, inexpensive, small and lightweight digital still camera or digital video camera, and to detect motion. Is obtained that can also perform correction for a shake exceeding the limit.

It is to be noted that the decrease in gain due to imaging of the sub-image at a high shutter speed may be compensated for in the same manner as in the second embodiment, and that only the main image with the blur corrected may be recorded. This is the same as in Embodiment 2. Further, the main image may be corrected using the outlines (processed intermediate information) of the plurality of sub-images. If the processing capacity of the arithmetic unit has a margin, the main image is corrected using the plurality of sub-images themselves. May be. Further, the imaging interval and the number of captured images of the sub-image may be changed according to the exposure time of the main image, and a more accurate blur parameter may be calculated.

Embodiment 4 Embodiment 4 of the present invention will be described with reference to FIGS. 8, 9, 32, 33, and 34. FIG. Regarding the configuration, the blurred image correction program executed by the microcomputer of the shutter control circuit includes:
Since the present embodiment is the same as the above-described first embodiment except that it is changed to the one shown by the flowcharts of FIGS. 32 to 34, the description is omitted.

As in the case of the second embodiment, a plurality of sub-images SV11 and SV12 whose shutter speed is increased are photographed immediately before or immediately after the main image MV1. As shown in FIG. 9, a plurality of sub-images SVij are provided for one main image MVi.
(J = 1, 2,...) (Step S15 in FIG. 32)
These are recorded as a pair, and the photographing interval time ti1 of the sub-image and the sub-image and the photographing exposure time (shutter speed) ti2 (= tr) of the main image are also recorded (FIG. 32).
Steps S16 and S25). The direction and magnitude of the blur are calculated by comparing a plurality of sub-images after photographing. The direction of the blur in the main image is almost equal to this, and the magnitude of the blur is obtained by multiplying the amount obtained from the sub-image by the ratio of the exposure time of the main image and the interval between the sub-images.
That is, in FIG. 8, the amount of blur in the main image is obtained by comparing li2, the shooting interval time between the sub-image and the sub-image is ti1, the shooting exposure time of the main image is ti2, and the sub-image SVi1 is compared with the sub-image SVi2. If the amount of movement (movement) is li1, then li2 = (ti2 / ti1) * li1. By doing so, it is not necessary to make the imaging interval time of the sub-image equal to the imaging exposure time of the main image, and it is not necessary to set both to a fixed ratio, and these can be set freely. Then, the motion vector thus obtained (step S17 in FIG. 32)
(Refer to step S18 in FIG. 32).

Further, using the above calculation, the sub-image SVi
1 and the imaging interval time of the sub-image SVi2 and the exposure time ti2 of the main image MVi1, the direction and the magnitude of the blur of the main image are calculated immediately after the imaging (see step S26 in FIG. 33), and the direction and the magnitude are calculated. Is recorded as a correction parameter PMi (see step S27 in FIG. 33) together with the main image as shown in FIG. 9B (step S2 in FIG. 33).
8), and by correcting the main image (see step S21 in FIG. 33), the consumption of the recording unit can be reduced. Furthermore,
While the main image is blur-corrected using these parameters (see step S30 in FIG. 34), only the main image RMVi subjected to the blur correction is recorded as shown in FIG. 9C (step S31 in FIG. 34). ), The consumption of the recording unit can be reduced, and the blur-corrected image can be recorded while being monitored in real time.

Also in this case, when the sub-image is taken with the shutter speed increased, the gain is reduced, so that the mechanical aperture 2 in FIG. It is assumed that the gain of the amplifier 7 is increased, the strobe 8 emits light, or a combination thereof is used to obtain an appropriate gain for the sub-image with the increased shutter speed.

As described above, according to the fourth embodiment, immediately before or immediately after the main image is taken, a plurality of sub-images are taken at a faster shutter speed than the main image is taken so as not to cause blurring. However, since the blur correction of the main image is performed by using the sub-image or the blur parameter obtained by calculating the shutter speed and the sub-image, the optical accuracy is increased when the number of pixels of the CCD is increased. Image stabilization can be realized without using a movable optical system, which requires stricter requirements, and it is possible to provide an image stabilization function to a portable, inexpensive, small, and lightweight digital still camera or digital video camera, and furthermore, to achieve motion detection. An object that can also perform correction for blur exceeding the limit is obtained. Note that the main image may be corrected using the contours of the plurality of sub-images, or the main image may be corrected using the plurality of sub-images themselves if the processing capability of the arithmetic unit has room.

The fifth embodiment of the present invention described in claim 0, 91 will be described with reference to FIGS. 10, 35, 36, and 37. FIG. As for the configuration, the blurred image correction program executed by the microcomputer of the shutter control circuit is shown in FIG.
Since it is the same as the first embodiment except that it is changed to the one shown in the flowchart of FIG. 5 to FIG. 37, the description is omitted.

In the fifth embodiment, similarly to the fourth embodiment, a plurality of sub-images are photographed by increasing the shutter speed immediately before or immediately after the main image, and a plurality of sub-images are taken for one main image. The photographing interval time ti1 between the image and the sub image, and the photographing exposure time (shutter speed) t of the sub image and the main image
s and ti2 are recorded. As shown in FIG.
At least one sub-image SVi1 and SVi1 before and after Vi
Vi2 is imaged and recorded (steps S32 and S32 in FIG. 35).
33), a blur parameter (motion vector) indicating the direction and magnitude of the blur is calculated from the sub-image or the sub-image (see step S34 in FIG. 35), and based on this, the main image is corrected (see FIG. 35). The blur parameter is recorded together with the main image (see step S35) (see steps S36 and S37 in FIG. 36), the main image is corrected (see step S38 in FIG. 36), or the main image is corrected (see FIG. 3).
7 (see step S40), and only the corrected main image is recorded (see step S41 in FIG. 37).

As described above, according to the fifth embodiment, at least one image immediately before and immediately after the main image is captured, and a plurality of images are recorded at a faster shutter speed than when the main image is captured so as not to cause blurring. Since the sub-image is imaged and the main image is corrected using the sub-image or the blur parameter obtained by calculating the sub-image, the amount of blur in the main image can be more accurately estimated. In addition, it is possible to realize image stabilization without using a movable optical system, which is expensive and requires stricter optical accuracy when the number of pixels of the CCD is increased, and is a portable, inexpensive, small and lightweight digital still camera or digital video camera. It is possible to provide a blur correction function. In addition, there can be obtained one that can also perform correction for a shake exceeding the limit of motion detection.

Note that the decrease in gain due to imaging of the sub-image at a high shutter speed may be compensated for in the same manner as in the second embodiment. Further, the main image may be corrected using the contours of the plurality of sub-images, or the main image may be corrected using the plurality of sub-images themselves if the processing capability of the arithmetic unit has room. Furthermore, the imaging interval and the number of captured images of the sub image may be changed according to the exposure time of the main image, and the blur parameter may be calculated more accurately.

A sixth embodiment of the present invention described in the eighth, 89, 90 and 91 embodiments will be described with reference to FIGS. 11, 12, 13, 38, 39 and 40. The configuration is the same as that of the first embodiment except that the blurred image correction program executed by the microcomputer of the shutter control circuit is changed to the one shown by the flowcharts of FIGS. The description is omitted.

In the sixth embodiment, similarly to the second and fourth embodiments, an apparatus having the configuration shown in FIG.
A plurality of sub-images SVi1, SVi2, SVi3, SV whose shutter speed is increased immediately before or immediately after Vi
Although i4 is photographed (see step S15 in FIG. 38), three or more sub-images are taken instead of two or more, and the main image and
Recording is performed as shown in FIG. 3A (see step S16 in FIG. 38).

[0135] Alternatively, the captured sub-image is
, The motion vectors vi1, vi2, vi3,... Are obtained as shown in FIG. This vector is detected as trajectory information (see step S42 in FIG. 38), and the main image is corrected (see step S43 in FIG. 38).

Alternatively, this trajectory information is recorded together with the main image instead of the sub image as shown in FIG. 13B (see step S45 in FIG. 39), and the main image is corrected (see step S46 in FIG. 39). These motion vectors v11, v12,
v13,... are the sub-images SV11, SV12, SV13,.
Contains relative position coordinate information. From the recorded trajectory information, a trajectory curve in FIG. 11, such as an arc, a quadratic function, and an Nth-order function (N is an integer of 3 or more), or a linear or polygonal function formula f1 is obtained by calculation. Assuming that the blur in the main image exists on the function formula f1, the blur correction of the main image is performed by performing a pixel separation operation using f1 as a coordinate axis.

As can be seen from FIG. 11, when the exposure time of the main image is long, the approximation error of the locus curve increases if the number of samples of the preceding and succeeding sub-images is small. Also, if the sampling interval of the sub-image is too short or too long, the approximation error of the locus curve increases, so that the number of sub-images is adjusted according to the exposure time of the main image to obtain the locus information, or Adjust the sampling interval of the sub-image according to the exposure time of the image,
It is assumed that the blur locus curve of the main image is accurately obtained.

When the exposure time of the main image is relatively short, for example, as shown in FIG. 12, the trajectory of the entire blur is approximated as a broken line from the trajectory of the sub-image, and the blur in the main image is obtained as a part of the broken line. Then, the dotted line in the figure and the amount of calculation are reduced. For example, the blur locus of the main image (indicated by a thick arrow in the figure) is such that the dotted lines predicted from the inclinations of the motion vectors v11, v12, and v13 are parallel and have a size corresponding to the exposure time of the main image. Can be approximately obtained as such a straight line. Then, recording is performed while correcting the main image by reducing the calculation amount and increasing the speed. Further, the main image is corrected as shown in FIG. 13C (see step S47 in FIG. 40), and the corrected main image RM
By recording only V1, RMV2, RMV3,... (See step S48 in FIG. 40), the recording capacity can be saved.

In this case, too, the gain decreases when the sub-image is taken at a high shutter speed, so that the mechanical aperture 2 in FIG. It is assumed that the gain of the amplifier 7 is increased, the strobe 8 emits light, or a combination thereof is used to obtain an appropriate gain of the sub-image with the increased shutter speed.

As described above, according to the sixth embodiment, immediately before or immediately after the main image is taken, a plurality of sub-images are taken at a faster shutter speed than when the main image is taken so as not to cause blurring. However, since the blur correction of the main image is performed using the sub-image or the blur locus obtained by calculating the sub-image, the amount of blur in the main image can be more accurately estimated, and the cost and the cost of the CCD are increased. When the number of pixels increases, blurring correction can be realized without using a movable optical system that requires stricter optical accuracy, and provides a camera-shake correction function for portable, inexpensive, compact and lightweight digital still cameras and digital video cameras. And a correction that can also be performed for a shake exceeding the limit of motion detection.

Note that the main image may be corrected using the contours (intermediate processing information) of a plurality of sub-images. The image may be corrected. Further, the shutter speed information of the main image, the shutter interval time information between the sub-images, or the blurring parameter of the main image obtained from these are recorded, the main image is corrected based on these, and only the corrected main image is recorded. You may make it.

(Embodiment 7) Next, claims 7, 9, 11, 12, 13 and 14 of the present invention will be described.

The seventh embodiment of the present invention described in the eighth, 89, 90 and 91 embodiments will be described with reference to FIGS.
This will be described with reference to FIGS. The configuration is the same as that of the first embodiment except that the blurred image correction program executed by the microcomputer of the shutter control circuit is changed to the one shown in the flowcharts of FIGS. The description is omitted.

As in the third and fifth embodiments, a plurality of sub-images are taken using the device having the structure shown in FIG. First, three or more images, not two or more, of one main image are imaged and recorded (see steps S45 and S16 in FIG. 41). Alternatively, the motion vectors v11, v12, v
13 ... is obtained. These motion vectors v11, v1
2, v13... As trajectory information (step S4 in FIG. 41).
2), and corrects the main image based on the trajectory information (see step S43 in FIG. 41). Alternatively, the trajectory information is recorded together with the main image instead of the sub image (see step S47 in FIG. 42), and the main image is corrected (see step S48 in FIG. 42). v11, v12, v13 ... are sub-images SV
., SV2, SV3,... From the recorded trajectory information, a trajectory curve in FIG. 14 or a function formula f1 of a straight line (in some cases, a broken line) is obtained by calculation. Assuming that the blur in the main image exists on this function f1, the main image is corrected by performing a pixel separation operation using the function f1 as a coordinate axis. By including the front and back of the main image as the sub-image, the blur locus in the main image can be better approximated, so that the locus calculation accuracy when the exposure time of the main image is long or the like is increased.

As can be seen from FIG. 14, when the exposure time of the main image is prolonged, the approximation error of the locus curve increases if the number of samples of the preceding and succeeding sub-images is small. Also, if the sampling interval of the sub-image is too short or too long, the approximation error of the trajectory curve increases, so that the trajectory information is obtained by adjusting the number of sub-images according to the exposure time of the main image, or The sampling interval of the sub-image is adjusted according to the exposure time, and the blur locus curve of the main image is accurately obtained.

When the exposure time of the main image is relatively short, for example, as shown in FIG. 15, the entire trajectory of the blur is approximated as a broken line from the sub-image trajectory, and the blur in the main image is obtained as a part of the broken line. Reduce the dotted line inside and the amount of computation. For example, the blur locus of the main image (indicated by the bold arrow in the figure) is parallel to the motion vector between the sub-images SV14 and SV15 immediately before and after the main image because the difference between the inclinations of the motion vectors v3 and v4 is small. Since it has a size corresponding to the exposure time of the image, it can be approximately obtained as such a straight line. Then, recording is performed while correcting the main image by reducing the calculation amount and increasing the speed. In this recording, the main image may be corrected (see step S49 in FIG. 43) and only the corrected main image may be recorded (FIG. 43).
Step S50).

In this case as well, the gain decreases when the sub-image is picked up at a higher shutter speed, so that the mechanical aperture 2 in FIG. 1 is opened or the optical filter 4 is switched to the one with a smaller effect to match the gain. It is assumed that the gain of the amplifier 7 is increased, the strobe 8 emits light, or a combination thereof is used to obtain an appropriate gain of the sub-image with the increased shutter speed.

As described above, according to the seventh embodiment, at least one immediately before and after the main image is captured.
A plurality of sub-images are captured at a shutter speed faster than that of capturing the main image so as not to cause blurring, and the main image is subjected to blur correction using the sub-image or a blur locus obtained by calculating the sub-image. This makes it possible to more accurately estimate the amount of blur in the main image, and realizes blur correction without using a movable optical system, which is expensive and requires stricter optical precision when the number of CCD pixels increases. This makes it possible to provide an image stabilization function to portable, inexpensive, small, and lightweight digital still cameras and digital video cameras, and also to obtain an image stabilization function that can perform image stabilization beyond the limit of motion detection. Can be Note that the main image may be corrected using the outlines (intermediate processing information) of a plurality of sub-images. If the processing capacity of the arithmetic unit has room, the main image may be corrected using the plurality of sub-images themselves. May be.

(Embodiment 8) Next, claims 28, 29, 30, 30, 32, 60, 61, 62, 64, and 64 of the present invention will be described. , Claim 92, Claim 93, Claim 94, Claim 96
Embodiment 8 of the present invention described in (1) will be described with reference to FIG. Note that the same components as those in the above-described embodiment are denoted by the same reference numerals, and description thereof is omitted.

As shown in FIG. 16, the shake image correcting apparatus according to the eighth embodiment includes two CCD solid-state imaging devices 5 and two CCD driving circuits 6 (CCD solid-state imaging devices 5a and 5a,
5B and the CCD drive circuits 6a and 6b), in that the blurred image correction program executed by the microcomputer of the shutter control circuit is changed to the one shown in the flowcharts of FIGS. 14 is 1
One spectroscope distributes imaging light to two CCD solid-state imaging devices 5a and 5b. The CCD drive circuits 6a and 6b, the amplifiers 9a and 9b, and the A / D converters 10a and 10b are configured to have a plurality of these so that two images can be captured at the same time. In addition, without providing the spectroscope 14,
The optical section before the CCD solid-state imaging device may be one for each CCD solid-state imaging device. Further, the imaging device may be configured with two or more channels.

When the shutter is depressed (see step S1 in FIG. 44) using such a multi-channel imaging system, and the shutter speed tri of the main image is blurred for a long time (see step S2 in FIG. 44). As shown in FIG. 17, the sub-image SVi has a short shutter speed tsi.
Is captured simultaneously with the main image MVi (see step S51 in FIG. 44), the main image and the sub-image are recorded (see step S54 in FIG. 44), and the main image is corrected by calculation from these (step S5 in FIG. 44). ), And obtains an image without blur due to blurring.

In addition, one of the two CCD solid-state imaging devices
One may be dedicated to capturing the sub-image as a high-sensitivity one that can obtain an appropriate gain in a short exposure time. However, as in the second embodiment, the gain in capturing the sub-image at a high shutter speed is reduced. The decrease may be compensated for.

Instead of recording the sub-image, processing intermediate information such as a contour image necessary for correcting the main image is obtained from the sub-image by calculation (see step S10 in FIG. 45), and is recorded in the recording device together with the main image. (Step S1 in FIG. 45)
1), and corrects the main image (step S12 in FIG. 45).
reference).

For this reason, it is possible to reduce the capacity of the recording unit by performing writing on the recording unit while correcting blurring of the main image by high-speed calculation. In this recording, after capturing the main image and the sub image (see step S51 in FIG. 46), a blur correction operation is performed (see step S13 in FIG. 46), and only the corrected main image is recorded (see step S14 in FIG. 46). By doing so, the capacity of the recording unit may be further reduced.

As described above, according to the eighth embodiment, a plurality of sub-images are captured at a shutter speed faster than that of the main image so as to prevent blurring in parallel with the main image. However, since the blur correction of the main image is performed using the sub-image or information obtained by calculating the sub-image, the blur amount in the main image can be estimated more accurately, and the CCD solid-state is expensive and expensive. When the number of pixels of the image sensor increases, blur correction can be realized without using a movable optical system that requires stricter optical accuracy, and the shake correction function can be used in portable, inexpensive, compact and lightweight digital still cameras and digital video cameras. Can be provided, and can also be performed for a shake that exceeds the limit of motion detection. The imaging system for the sub-image may capture the sub-image at the timing shown in the first to seventh embodiments.

(Embodiment 9) Next, claim 28, claim 29, claim 30, claim 31, and claim 3 of the present invention.
2, and claim 60, claim 61, claim 62, claim 63, claim 64, claim 92, claim 93,
A ninth embodiment of the invention described in claims 94, 95, and 96 will be described with reference to FIG. The configuration is the same as that of the eighth embodiment described above, except that the blurred image correction program executed by the microcomputer of the shutter control circuit is changed to the one shown in the flowcharts of FIGS. different.

As in the case of the eighth embodiment, a sub-image whose shutter is controlled to be shorter than that of the main image is picked up simultaneously with the main image by using the apparatus having the structure as shown in FIG. 16, but as shown in FIG. A plurality of sub-images (SVi1, SVi2 in this example) are imaged within or near the exposure time tri (SVi1, SVi2 in this example) (see step S52 in FIG. 47), and these are recorded (see step S4 in FIG. 47), thereby blurring from the sub-image. The amount is calculated and the main image is corrected (see step S5 in FIG. 47). Further, as a configuration of the apparatus, there are two or more imaging systems for capturing a sub-image, and the temporally continuous sub-image SVi as shown in FIG.
1 and SVi2 may be individually captured and recorded by switching the imaging system at short intervals. However, a CCD solid-state imaging device for capturing a sub-image uses a high-sensitivity device that can obtain an appropriate gain in a short exposure time. However, similar to the second embodiment, when capturing a sub-image at a high shutter speed, A reduction in gain may be compensated.

As shown in FIG. 19, the main image MVi
The sub-image SVi to be imaged and recorded at a shorter shutter speed tsi in accordance with the shutter speed tri
By increasing or decreasing the number of SVi1, SVi2, and SVi3, it is possible to accurately calculate the blur amount when the exposure time of the main image becomes long. Also, as shown in FIG. 20, the main image MVi
The interval ti1 between the sub-images SVi1 and SVi2 to be imaged and recorded may be increased or decreased in accordance with the shutter speed tri to cover the blur of the main image.

Further, instead of recording the sub-image, processing intermediate information such as a contour image necessary for correcting the main image is obtained from the sub-image by calculation (see step S10 in FIG. 48) and this is stored in the recording device together with the main image. By recording (see step S11 in FIG. 48) and correcting the main image (see step S12 in FIG. 48), the amount of calculation after imaging is reduced.

For this reason, the writing to the recording unit is performed while correcting the blur of the main image by high-speed calculation, thereby reducing the capacity of the recording unit. In this recording, after capturing the main image and the sub image (see step S52 in FIG. 49), a blur correction operation is performed (see step S13 in FIG. 49), and only the corrected main image is recorded (see step S14 in FIG. 49). You may make it.

As described above, according to the ninth embodiment, in parallel with the imaging of the main image, it is faster than the imaging of the main image such that the blur does not occur within or near the exposure time of the main image. A plurality of sub-images are imaged at the shutter speed, and the main image is shake-corrected using the sub-image or information obtained by calculating the sub-image, so that the amount of blur in the main image can be more accurately estimated. In addition to this, it is possible to perform image stabilization without using a movable optical system, which is expensive and requires stricter optical accuracy when the number of pixels of the CCD solid-state imaging device is increased. It is possible to provide a still camera or a digital video camera with a blur correction function, and to obtain a camera capable of correcting a blur exceeding the limit of motion detection. The imaging system for the sub-image may capture the sub-image at the timing shown in the first to seventh embodiments.

The configuration is the same as that of the eighth embodiment described above, except that the blurred image correction program executed by the microcomputer of the shutter control circuit is changed to the one shown by the flowcharts in FIGS. different. In addition, a CCD solid-state imaging device for capturing a sub-image is to use a high-sensitivity device capable of obtaining an appropriate gain in a short exposure time. In this case, it is possible to compensate for a decrease in gain.

As in the eighth embodiment, a plurality of sub-images (SVi1, SVi in this example) using a device having the structure shown in FIG.
Vi2) is imaged (see step S51 in FIG. 50) and recorded (see step S4 in FIG. 50). Simultaneously, the shutter speed (exposure time) of the main image in FIG.
t12 and shutter interval time information t11 of the sub-image are recorded (see step S53 in FIG. 50), the blur amount l12 of the main image is calculated as a ratio from the motion amount l11 between the sub-images, and the main image after recording can be corrected. (Fig. 5
0, see step S54).

This calculation is immediately performed at the time of imaging, and the main image and the parameters corresponding to the calculated direction and magnitude of the blur are detected instead of the sub-image (see step S55 in FIG. 51) and recorded (see FIG. 51). (See step S56), and the main image after recording may be corrected (see step S57 in FIG. 51).

The main image may be corrected immediately (see step S59 in FIG. 52) from the parameters obtained by the shake correction calculation (see step S59 in FIG. 52) and recorded (step S59 in FIG. 52). See S60). Alternatively, the number of sub-images to be imaged and recorded may be increased or decreased according to the shutter speed of the main image so that the blur amount when the exposure time of the main image becomes long can be accurately calculated. Further, the interval between the sub-images to be captured and recorded may be increased or decreased according to the shutter speed of the main image to cover the shake of the main image.

Further, even if the sampling interval is too short, it is not possible to cover the fluctuation of the main image, so the sampling interval of the sub-image is adjusted according to the length of the main image. In addition, a CCD solid-state imaging device for capturing a sub-image that has high sensitivity to obtain an appropriate gain in a short exposure time is used. Further, the trajectory calculation is immediately performed at the time of imaging (see step S64 in FIG. 54), and the main image and the calculated motion vectors v1, v
