  Next, the operation of the camera according to the first embodiment will be described. 2 and 3 are flowcharts of a main routine of the camera 100 according to the present embodiment.

  First, upon power-on such as battery replacement, the system control circuit 50 initializes flags, control variables, and the like (step S101), and initializes the image display of the image display unit 28 to an OFF state (step S102). Next, the system control circuit 50 determines the setting position of the mode dial switch 60 (step S103).

  If the mode dial switch 60 is set to power OFF in step S103, the display on each display unit is changed to the end state, the barrier 102 is closed, and the imaging unit is protected. Further, necessary parameters, setting values and setting modes including flags and control variables are recorded in the non-volatile memory 56, and unnecessary power sources for various parts of the camera 100 including the image display unit 28 are shut off by the power source control unit 80. A predetermined end process is performed (step S105). Thereafter, the process returns to step S103.

  If the mode dial switch 60 has been set to the reproduction mode in step S103, the system control circuit 50 executes the reproduction process (step S104). When the process is completed, the process returns to step S103. The reproduction mode process in step S104 will be described later with reference to FIG.

  If the mode dial switch 60 is set to the shooting mode in step S103, the process proceeds to step S106. The system control circuit 50 determines whether or not the remaining capacity of the power source 86 such as a battery or the operation status has a problem in the operation of the camera 100 by the power source control unit 80 (step S106). If there is a problem with the power supply 86, a predetermined warning is displayed by image or sound using the display unit 54 (step S108), and then the process returns to step S103.

  If there is no problem with the power supply 86 (step S106), the system control circuit 50 determines whether the operation state of the recording media 200 and 210 is a problem with the operation of the camera 100, particularly with respect to the recording / reproducing operation of the image data with respect to the recording medium. Is determined (step S107). If there is a problem in the operation state of the recording media 200 and 210, a predetermined warning display is performed by an image or sound using the display unit 54 (step S108), and the process returns to step S103.

  If there is no problem in the operation states of the recording media 200 and 210 (step S107), the system control circuit 50 displays various setting states of the camera 100 using images and sounds using the display unit 54 (step S109). If the image display of the image display unit 28 is ON, various setting states of the camera 100 are displayed by an image or sound using the image display unit 28.

  The system control circuit 50 sets a through display state in which captured image data is sequentially displayed (step S116), and proceeds to step S120 in FIG. In the through display state, data sequentially written in the image display memory 24 via the image sensor 12, the A / D converter 16, the image processing circuit 20, and the memory control circuit 22 is converted into the memory control circuit 22 and the D / A conversion. Images are sequentially displayed by the image display unit 28 via the device 26. The electronic viewfinder function is realized by this through display state.

  The system control circuit 50 checks the state of the recording SW (step S120), and starts recording moving images if the recording SW is ON. Here, the recording SW may be assigned to one of the various buttons of the operation unit 70, or may be assigned to the shutter switch SW2 when the photographing mode is set.

  When recording a moving image, first, the system control circuit 50 records the posture information of the camera 100 detected at the start of moving image capturing (at the start of recording) by the posture detector 58 on the recording medium 200 or 210 (step S121). . Then, a moving image including sound is recorded (step S122), and the moving image is continuously recorded until the recording SW is turned off (step S123). As described above, in this embodiment, the posture information of the camera detected at the start of recording of moving image data is also recorded on the recording medium 200 or 210 together with the moving image data.

FIG. 4 is a detailed flowchart of the playback mode in step S104 of FIG. In the reproduction mode, the system control circuit 50 detects the rotation angle A, which is the current posture information of the camera 100, by the posture detector 58 (step S140). Next, the rotation angle B, which is the posture information of the camera 100 detected at the start of moving image recording, is read from the recording medium 200 or 210, and the rotation angle α at the time of reproduction is obtained by the following equation (step S141).
Playback angle α = Current angle A-Shooting angle B

  When the playback angle α is obtained, the system control circuit 50 reads the moving image start frame from the recording medium 200 or 210, rotates it to the playback angle α, and displays it on the image display unit 28 (referred to as “stop” in the present invention). Movie display ") (step S142).

  Next, the system control circuit 50 determines whether or not there is an instruction to start reproduction (step S143). Until there is an instruction to start reproduction, the processes in steps S140 to S142 are repeated. In this way, until a moving image reproduction start instruction is issued, the start frame of the moving image is sequentially rotated based on the posture information (rotation angle A) of the camera 100 detected by the posture detector 58 to display an image. Displayed on the unit 28.

  If there is an instruction to start reproduction in step S143, the posture detection of the camera 100 is terminated, and the moving image is reproduced with the rotation direction fixed with the rotation angle α calculated in step S141 (step S144). . As described above, since the rotation direction to be reproduced is determined before starting the reproduction of the moving image, even if the posture detector 58 detects a subtle change after the reproduction of the moving image is started, the rotation to reproduce the moving image is performed. It is possible to reproduce a moving image that is easy to see for the user without changing the direction.

  The system control circuit 50 continues to play the moving image until an instruction to stop playback is given (step S145). If there is an instruction to stop playback and subsequently an instruction to end the playback mode, the playback mode is ended. If there is no instruction to end the reproduction mode, that is, if the reproduction mode is still paused, the process returns to step S140 to continue the reproduction mode process (step S146). As described above, after the playback of the moving image is stopped, the start frame of the moving image is sequentially rotated based on the posture information of the camera 100 detected by the posture detector 58 until the playback mode itself ends. The image is displayed on the image display unit 28.

  With reference to FIG. 5, the rotation axis for detecting the posture of the camera will be described. The user may shoot with the camera in the horizontal / vertical position. The horizontal position and the vertical position are based on the angle rotated about the X rotation axis with the normal direction to the photographing surface of the camera as an axis as shown in FIG. That is, the posture information reflected by the system control circuit 50 during reproduction or recording refers to a rotation angle about the X rotation axis. Although the Y axis and Z axis can be considered as the rotation axis of the camera, the purpose is to determine the vertical position and the horizontal position to the last, so the attitude detector that can detect the rotation angle around the X rotation axis 58 is installed.

  With reference to FIG. 6, the rotation angle that can be determined by the attitude detector 58 will be described. Some attitude detectors can determine the angle finely, but the cost increases. Therefore, in this embodiment, as shown in FIG. 6, an attitude detector 58 that can detect only four directions of 0 ° / 90 ° / 180 ° / 270 ° is used.

  That is, the posture detector 58 is such that when the upper component in the vertical direction is located within the rotation angle of −45 ° to 45 ° in FIG. 6, the camera is at the rotation angle of 0 °, that is, the camera is in the lateral position. Is determined. Further, when the upper component in the vertical direction is located within the rotation angle of 45 ° to 135 ° in FIG. 6, it is determined that the camera is rotated by 90 °, that is, the camera is in the vertical position. Further, when the upper component in the vertical direction is located within the rotation angle of 135 ° to 225 ° in FIG. 6, it is determined that the camera is rotating 180 °, that is, the camera is in the horizontal position. Further, when the upper component in the vertical direction is located within the rotation angle of 225 ° to −45 ° in FIG. 6, it is determined that the camera is rotated by 270 °, that is, the camera is in the vertical position. If these four directions can be determined, the vertical position and the horizontal position can be determined without hindrance.

  With reference to FIG. 7, a case where the posture detector 58 cannot correctly detect the rotation angle of the camera will be described. When the X rotation axis of the camera is orthogonal to the vertical direction as shown in FIG. 7A, the rotation angle of the camera can be normally detected. On the other hand, as shown in FIGS. 7B and 7C, when the camera rotates downward / upward about the Y rotation axis, the rotation angle of the camera cannot be detected. Here, in the case of a conventional camera, if the camera is turned downward or upward as shown in FIGS. 7B and 7C during the reproduction of a moving image, an abnormal posture is detected. In some cases, the rotation process of the moving image is performed and the rotation direction of the moving image is changed. However, in this embodiment, a moving image is rotated based on posture information detected immediately before the start of moving image reproduction, and posture detection is not performed after the start of reproduction. Therefore, even if the camera is in the posture shown in FIGS. 7B and 7C during the reproduction of the moving image, the rotation direction is not changed during the reproduction, and the reproduction of the moving image that is easy for the user to see is possible. It can be performed.

  With reference to FIG. 8 and FIG. 9, reproduction of a moving image will be described. Incidentally, the reproduction angle in the figure means an angle rotated clockwise around the X rotation axis. FIG. 8A shows an example of a moving image shot in the horizontal position. Since the camera is in the horizontal position while 1 is stopped, the start frame of the moving image is displayed without being rotated. Since the camera is in the vertical position while 2 is stopped, the start frame of the moving image is also rotated and displayed. Further, since the camera returns to the horizontal position during the stop of 3, the original display is performed without rotating the start frame of the moving image. Next, when the reproduction of the moving image 4 is started, the reproduction of the moving image is started in the state in which the previous 3 is stopped. If the camera is set to the vertical position during reproduction in step 5, the moving image is not rotated.

  FIG. 8B shows an example of a moving image shot in the horizontal position. Since the camera is in the horizontal position while 1 is stopped, the start frame of the moving image is displayed without being rotated. Since the camera is in the vertical position while 2 is stopped, the start frame of the moving image is also rotated and displayed. Next, when the reproduction of the moving image 3 is started, the reproduction of the moving image is started with the state 2 immediately before being stopped. 4, the moving image is not rotated even if the camera is set to the horizontal position during reproduction.

  FIG. 9A shows an example of a moving image shot in the vertical position. Since the camera is in the horizontal position while 1 is stopped, the start frame of the moving image is rotated and displayed. Since the camera is in the vertical position while 2 is stopped, the moving image start frame is not rotated and is displayed as it is. Furthermore, since the camera returns to the horizontal position during the stop of 3, the start frame of the moving image is rotated again and displayed. Next, when the reproduction of the moving image 4 is started, the reproduction of the moving image is started in the state in which the previous 3 is stopped. If the camera is set to the vertical position during reproduction in step 5, the moving image is not rotated.

  FIG. 9B shows an example of a moving image shot in the vertical position. Since the camera is in the horizontal position while 1 is stopped, the start frame of the moving image is rotated and displayed. Since the camera is in the vertical position while 2 is stopped, the moving image start frame is not rotated and is displayed as it is. Next, when the reproduction of the moving image 3 is started, the reproduction of the moving image is started with the state 2 immediately before being stopped. Even if the camera is set to the vertical position during reproduction in step 4, the moving image is not rotated.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to FIG. The configuration of the camera 100 including the image processing apparatus according to the second embodiment is the same as that shown in FIG. The operation of the camera 100 according to the second embodiment is obtained by replacing the flowchart of FIG. 4 which is a reproduction routine in the first embodiment with the flowchart of FIG. That is, FIG. 10 is a detailed flowchart of the reproduction mode in step S104 of FIG.

The system control circuit 50 detects the rotation angle A, which is the current posture information of the camera 100, by the posture detector 58 (step S190). Next, the rotation angle B, which is the attitude information of the camera 100 detected at the start of moving image recording, is read from the recording medium 200 or 210, the rotation angle B is stored in the memory 32, and the rotation angle α at the time of reproduction is Obtained by an equation (step S191).
Playback angle α = Current angle A-Shooting angle B

  After obtaining the reproduction angle α, the system control circuit 50 reads the moving image start frame from the recording medium 200 or 210, rotates it to the reproduction angle α, and displays it on the image display unit 28 (step S192).

  Next, the system control circuit 50 determines whether or not there is an instruction to start reproduction (step S193). Until there is an instruction to start reproduction, the processes in steps S190 to S192 are repeated. As described above, until a moving image reproduction start instruction is issued, the moving image start frame is sequentially rotated based on the camera posture information detected by the posture detector 58 and displayed on the image display unit 28.

  If there is an instruction to start playback in step S193, the elapsed time from the playback start time of the moving image is checked (step S194). If the predetermined time is exceeded, the process proceeds to step S197. If within the predetermined time, the system control circuit 50 detects the rotation angle A, which is the current posture information of the camera 100, by the posture detector 58 (step S195). Next, the rotation angle B at the start of moving image recording is read from the memory 32, and the rotation angle α at the time of reproduction is obtained by the same expression as in step S191 (step S196), and then the process proceeds to step S197.

  In step S197, the moving image is reproduced with the rotation direction fixed at the rotation angle α. The system control circuit 50 continues to play the moving image until an instruction to stop playback is given (step S198). If there is an instruction to stop playback and subsequently an instruction to end the playback mode, the playback mode is ended. If there is no instruction to end the reproduction mode, that is, if the reproduction mode is still paused, the process returns to step S190 to continue the reproduction mode process (step S199). As described above, after the stop of the playback of the moving image, the start frame of the moving image is sequentially rotated based on the camera posture information detected by the posture detector 58 until the playback mode itself ends, It is displayed on the display unit 28.

  In the present embodiment, the posture of the camera is detected by the posture detector 58 within a predetermined time (predetermined time) from the start of reproduction. Therefore, if the user does not like the rotation direction in which the moving image is started to be reproduced, the rotation direction in which the moving image is reproduced is changed by changing the posture of the camera 100 within a predetermined time after the reproduction is started. be able to. On the other hand, after a predetermined time elapses, it is rarely desired to change the rotation direction. Further, when a low-cost posture detector is used, there may be a false detection of a subtle posture change. Therefore, by not performing posture detection after a predetermined time has elapsed, it is possible to reproduce a moving image that is easy for the user to see.
