Description

  The present invention relates to an imaging device that controls still image shooting operation in accordance with camera shake that occurs during still image shooting, and enables shooting of still images without camera shake.

  2. Description of the Related Art Conventionally, an electronic camera or an electronic photographing device called a digital still camera or a video camera that generates an electric image signal of a still image and a moving image by using a solid-state imaging device that photoelectrically converts a subject image and records it on a recording medium (Hereinafter simply referred to as an electronic camera) has been put into practical use. In recent years, electronic cameras that can capture both moving images and still images with a single electronic camera have been put into practical use. Furthermore, the electronic camera is reduced in size and weight due to the increase in the number of pixels of the solid-state imaging device, and the handling operation is simplified.

  The electronic camera can be easily captured without missing a photographing opportunity because the user can directly hold the electronic camera with his / her hand and perform the photographing operation. However, when the user directly holds the electronic camera in his / her hand, a so-called camera shake occurs in which the electronic camera is shaken depending on the holding state of the user.

  This camera shake can be solved by attaching and fixing an electronic camera on a tripod, but if the user directly holds the camera with his / her hand, the camera shake always occurs although the degree of camera shake is different. In addition, camera shake is relatively less likely to be affected by camera shake in a moving image. However, when a still image is shot and the shutter speed is slow, the shot image may be shifted due to camera shake. In order to minimize the effect of camera shake when shooting with an electronic camera, the camera shake detection function and the optical camera shake correction function that adjusts the photographic optical system lens by camera shake detection, or when camera shake occurs 2. Description of the Related Art An electronic camera with an anti-shake function having an electric camera shake correction function for correcting a photographed image by electric signal processing has been put into practical use.

  For example, Patent Document 1 proposes an electronic camera with a camera shake prevention function. In the electronic camera proposed in Patent Document 1, when a recording instruction is given by a still image shooting operation switch, the control unit captures still image data generated by a solid-state imaging device or the like for a predetermined period or a predetermined number of times. And, by detecting the amount of blur from the blur detection unit at the time of shooting for each captured still image data, compare the amount of blur for each captured still image data, and use the still image data with the least amount of blur on the recording medium. It is to be recorded.

Thus, when the shooting operation switch is operated in order to select and record a still image with the least amount of camera shake from a still image shot for a predetermined period or a predetermined number of times when the operation switch for still image shooting is operated. It is always possible to shoot still images.
JP-A-11-317904

  The electronic camera with an anti-shake function proposed in Patent Document 1 performs still image shooting a plurality of times within a predetermined time in one still image shooting, and detects the amount of camera shake for each still image shooting. The still image with the smallest amount of camera shake at the time of each still image recording is recorded, but the still image with the smallest amount of camera shake is selected from among all the still images to be compared. . For this reason, there is a problem that the selected still image becomes a still image with a shift due to camera shake.

  Also, in the above-mentioned document 1, if a still image with a camera shake amount of a predetermined value or less is detected in one still image shooting, a still image with a predetermined camera shake amount or less is taken for a predetermined time or a predetermined number of times of still image shooting. At this time, recording on a recording medium is intended to speed up shooting and recording.

  However, if a still image with a predetermined amount of camera shake or less cannot be captured, the still image with the minimum amount of camera shake during a single recording will be recorded, and the recorded still image will be shifted due to camera shake. There is a problem that becomes a still image.

Let

  The digital moving image data temporarily stored in the memory unit 14 is read from the memory unit 14 under the control of the microcomputer 25, and the read digital moving image data is decompressed by the JPEG / MPEG compression / decompression processing unit 13. The decoded image is converted into a digital moving image signal and supplied to the video demodulator 15. The video demodulator 15 demodulates the supplied digital moving image signal. The LCD control unit 16 displays the demodulated moving image signal on the LCD 17 as a subject image. From the subject image displayed on the LCD 17, the user confirms a recorded image at the time of moving image shooting.

  Further, the microcomputer 25 records the digital moving image data temporarily stored in the memory unit 14 in the HDD 19 or the memory card 20 in a predetermined file format.

  When the shutter button 33 is pressed for still image shooting in the shooting mode, the microcomputer 25 takes out an electrical signal at the time when the shutter button 33 is pressed down from a CCD (not shown) via the bus 30. Then, the analog signal processing unit performs predetermined signal processing to generate an analog still image signal. The analog still image signal is converted into a digital still image signal by an analog / digital conversion unit and supplied from the input terminal 11 to the signal processing unit 12. Under the control of the microcomputer 25, the signal processing unit 12 performs digital signal processing such as color difference correction, contour correction, and γ correction on the digital still image signal supplied to the input terminal 11 to perform JPEG / MPEG.

  Further, the microcomputer 25 records the digital still image data temporarily stored in the memory unit 14 in the HDD 19 or the memory card 20 in a predetermined file format.

  As described above, when camera shake occurs during still image shooting, the captured still image is displaced, which causes a reduction in image quality of the recorded video. However, when the user holds the photographing device directly with his / her hand and takes a picture, the occurrence of camera shake cannot be completely eliminated. In particular, camera shake occurs when the shutter button 33 is operated, or camera shake occurs when the camera apparatus body 31 is quickly held in order to take a picture without missing a shooting opportunity. On the other hand, if you restrict shooting while camera shake is detected, you will miss a shooting opportunity, and you can shoot multiple still images within one still image period and check the camera shake status for each still image. Even if a still image with the least amount of camera shake is recorded, there is no guarantee that the recorded still image is not misaligned.

  In the photographing apparatus according to the embodiment of the present invention, when the gyro sensor 28 at the time of still image photographing detects camera shake, the microcomputer 25 is provided with photographing control means for controlling the operation of still image photographing according to the state of camera shake.

  The photographing control means provided in the microcomputer 25 of the photographing apparatus main body 31 of the photographing apparatus of the present invention is a camera shake in which the user adopts the camera shake detection result detected by the gyro sensor 28 which is the camera shake detecting means according to the photographing situation. Camera shake detection acceptance / rejection setting means is provided for selecting result-adopted shooting and camera-shake result non-adopted shooting for shooting without adopting the camera shake detection result. When the camera shake detection adoption setting means that the camera shake result adoption shooting is selected, the camera shake detected by the gyro sensor 28 serving as the camera shake detection means is photographed when the camera shake detected by the gyro sensor 28 is below a predetermined level for a certain period of time or within a predetermined level range for a certain period of time. To do. Further, when the camera shake detection rejection setting means that the camera shake result non-adopting shooting is selected, shooting is possible regardless of the camera shake detected by the gyro sensor 28 which is the camera shake detection means, and camera shake is notified when there is camera shake at the time of shooting. When the camera shake is equal to or lower than a predetermined level, photographing is performed again.

  The operation of the photographing control means based on the camera shake detection provided in the microcomputer 25 will be described with reference to FIG. The microcomputer 25 of the electronic photographing apparatus main body 31 slides the mode lever 43 of the input key unit 26 to the playback mode by the user and operates the menu button 42 of the input key unit 26 to display a plurality of operation menus on the LCD 17. At the same time, a camera shake detection acceptance / rejection setting menu, which is camera shake detection acceptance / rejection selection means, is selected from a plurality of displayed operation menus, and any one of camera shake detection acceptance / rejection is selected and set.

  The microcomputer 25 of the photographing apparatus main body 31 determines whether or not the shutter button 33 of the input key unit 26 is pressed on by the user in step S1 for still image photographing. If it is determined in step S1 that the shutter button 33 has been pressed down, the microcomputer 25 adopts or rejects the camera shake detection result from the camera shake detection acceptance / rejection setting menu by the menu button 42 of the input key unit 26 in step S2. It is determined whether or not the camera shake determination is valid. As a result of the determination in step S2, if it is determined that the camera shake determination is invalid and the non-adoption of the camera shake detection result is set, the microcomputer 25 causes the still image shooting to be performed regardless of the presence or absence of the camera shake in step S4. .

  As a result of the determination in step S2, if it is determined that the use of the camera shake detection result is valid, the microcomputer 25 determines in step S3 based on the camera shake state detected by the gyro sensor 28. Then, whether or not camera shake is occurring or not is determined.

  If the microcomputer 25 determines that there is no camera shake in step S3, still image shooting is performed in step S4.

  In step S4, the photographed still image signal photoelectrically converted by a CCD (not shown) is subjected to digital signal processing by the signal processing unit 12, and JPEG / MPEG compression / decompression processing unit 13 performs encoding and compression processing by the JPEG method. Is done. The compressed digital still image data is recorded in the HDD 19 or the memory card 20 via the memory unit 14, demodulated by the video demodulation unit 15, and displayed as a captured still image on the LCD 17 via the LCD control unit 16. Is done.

  Next, the camera shake determination in step S3 will be described with reference to FIG. In step S11, the microcomputer 25 acquires the output of the camera shake detection result detected by the gyro sensor 28. In step S12, the microcomputer 25 determines whether or not the camera shake output from the gyro sensor 28 acquired in step S11 is equal to or less than a certain level as a first criterion for a certain period of time. Alternatively, as a second determination criterion, it is determined whether the amount of change in camera shake is within a certain level range.

  The camera shake is a camera shake with a relatively large amplitude that occurs immediately after the shutter button 33 is pressed on, and gradually converges after a certain period of time. There is a camera shake having a large amplitude when the operation is stopped, and a camera shake that gradually converges after a certain period of time. Furthermore, there is a camera shake with a relatively small amplitude that occurs constantly during shooting.

  In the case of camera shake with a relatively large amplitude when the shutter button 33 is pressed on or when a quick operation is performed, the microcomputer 25 converges the large camera shake, which is the first determination criterion, so that the camera shake level in the time direction for a certain period is predetermined. When the value becomes equal to or less than the value, control is performed such that the photoelectric conversion is performed by the CCD and a still image is captured and processed by the signal processing unit 12 and the JPEG / MPEG compression / decompression processing unit 13.

  In the case of camera shake with a relatively small amplitude that occurs constantly, the microcomputer 25 determines whether the camera shake level for a certain period, which is the second criterion, is within a predetermined level range. Then, the image is photoelectrically converted by the CCD, a still image is taken in, and the signal processing unit 12 and the JPEG / MPEG compression / decompression processing unit 13 are controlled to perform processing.

  That is, in step S12, when the microcomputer 25 determines that the camera shake from the gyro sensor 28 is below the predetermined level or within the predetermined level range based on either the first determination criterion or the second determination criterion, The processing without camera shake in step S13 is executed.

  In step S12, when the microcomputer 25 determines that the camera shake from the gyro sensor 28 is greater than or equal to a predetermined level or out of the predetermined level range based on either the first determination criterion or the second determination criterion. During the camera shake in step S14, the still image shooting standby state is set until the camera shake satisfies the first and second determination criteria.

  Thus, in this embodiment, it is possible to shoot in a camera shake state that does not adversely affect the image quality of a still image taken when the shutter button 33 is pressed down.

  Note that, in the determination of step S2, in order to shoot without losing the shooting chance, in the camera shake detection result acceptance / rejection setting menu, when the adoption of the camera shake detection result is selected, the point in time when the shutter button 33 is pressed on. A still image is taken, and a camera shake detection result is output from the gyro sensor 28 at the time of the taking. Therefore, although not shown, the microcomputer 25 shoots when the shutter button 33 is pressed down when the result of camera shake detection from the gyro sensor 28 at the time of still image shooting is equal to or higher than a predetermined level or out of a predetermined level range. In some cases, the camera shake is notified that camera shake has occurred, and when the camera shake detected by the gyro sensor 28 falls below a predetermined level for a certain period of time, control is performed to take a still image again. It is also possible to take a still image in which there is a slight time shift but no camera shake.

  As a result, the user can shoot without missing a shooting opportunity and record the image by comparing the recognition of the occurrence of camera shake during shooting with the shooting in the state of shaking and the shooting without shaking. You can also choose to do it.

  In addition, the notification of the occurrence of camera shake during still image shooting is displayed on the LCD 17 of the monitor unit 37 by the display of the camera shake, or the speaker 38 outputs a beep sound or a camera shake generation sound.

  As described above, the present invention is provided with the camera shake detection result acceptance / rejection means for determining whether or not to adopt the camera shake detection result by the gyro sensor 28 as the camera shake detection means for the photographing operation. If it is set to be adopted, still image shooting with little influence of camera shake is possible when camera shake from the gyro sensor 28 is below a predetermined level or within a predetermined level range. In addition, when setting the camera shake detection result acceptance / rejection means to reject the camera shake detection result, it is possible to shoot without missing a shooting opportunity, and it is notified that camera shake has occurred during shooting, and the camera shake is below a predetermined level, Alternatively, a still image can be taken again when the level is within a predetermined level range.
