  Hereinafter, preferred embodiments will be described using a digital camera to which the present invention is applied according to the drawings. FIG. 1 is a block diagram showing the configuration of a camera 10 according to the first embodiment of the present invention. The camera 10 includes an image processing and control unit 1, an imaging unit 2, a face detection unit 2a, a recording unit 4, an acceleration detection unit 5, an inclination detection 7, an operation determination unit 6, a display unit 8, a touch panel 8b, and a watch unit 9. doing.

  The imaging unit 2 includes an imaging element that photoelectrically converts an object image formed by the photographing lens 2 b (see FIG. 5), and outputs image data to the image processing and control unit 1 or the like. The face detection unit 2a receives the image data output from the imaging unit 2 and subjected to image processing by the image processing and control unit 1 and determines whether the image includes a face or not, and the face is included. If it does, the position etc. is detected. The image processing and control unit 1 performs image processing of the image data output from the imaging unit 2. Further, the image processing and control unit 1 controls the entire camera 10 according to a program stored in advance in a storage unit (not shown). As image processing, still image processing and moving image processing can be performed.

  In the image processing and control unit 1, a first power control unit 1a, a second power control unit 1b, a third power control unit 1c, and a gravity determination unit 1d are provided. The first power supply control unit 1a controls power supply to the display unit 8 having a backlight and the like that consumes the largest amount of power, and to the imaging system and the like including the image capturing unit 2 and the face detecting unit 2a and the like having the largest power consumption next Do. When power is supplied by the first power control unit 1a, the camera 10 can perform a normal operation.

  The second power supply control unit 1 b performs AD conversion of the acceleration detection signal from the acceleration detection unit 5 and controls power supply to a gravity determination unit 1 d or the like described later. The third power control unit 1c controls power supply to the touch panel 8b. It should be noted that the comparator 5a in the acceleration detection unit 5 is supplied with power with micro power (10 μW level) even when the power is off, and detects a vibration of a predetermined value or more in any of three axes or one axis. A signal is output from the comparator 5a. When power supply to the gravity determination unit 1d is started from the second power supply control unit 1b, further power supply is continuously performed to the acceleration detection unit 5 and the gravity determination unit 1d, and fine vibrations can be detected.

  The gravity determination unit 1d is a determination unit that determines a change in gravity depending on how the camera 10 is held or moved, and further detailed acceleration, and receives the detection output of the acceleration sensor 50 from the acceleration detection unit 5 described later. It has an AD converter that AD converts the detection output. Further, the gravity determination unit 1 d determines gravity based on the magnitude of the acceleration applied to the camera 10 based on the detection output of the acceleration sensor 50 that has been A / D converted.

  The acceleration detection unit 5 detects an acceleration applied to the camera 10. In order to detect the longitudinal direction of the camera 10, the direction orthogonal to the longitudinal direction, etc., the acceleration detection unit 5 has acceleration sensors 50 arranged at three locations, each of which detects an acceleration. The acceleration detection unit 5 is connected to a comparator 5a that determines whether the detection output from the acceleration sensor 50 is larger than a predetermined value. The power consumption of the comparator 5a is extremely small, on the order of 10 μA. The output of the comparator 5a is connected to the image processing and control unit 1 and can perform interrupt processing. Further, the detection output (analog) of the acceleration sensor 50 is connected to the AD converter of the gravity determination unit 1d as described above.

  The vibration of the camera 10 is detected by the acceleration detected by the acceleration detection unit 5, and shake prevention in the imaging unit 2 is performed by a vibration isolation mechanism (not shown). Further, the tilt state of the camera 10 is determined using the detection result of the acceleration detection unit 5 and is used in the power control as described later. Also, it is used in the determination of whether or not the camera 10 is held firmly. Further, the acceleration detection unit 5 can detect the direction of gravity other than the acceleration, and can be used to determine whether the camera 10 is positioned in the vertical composition or the horizontal composition. The details of the acceleration detection unit 5 will be described later with reference to FIG.

  The tilt detection unit 7 detects the tilt state of the camera 10. The structure of the tilt detection unit 7 will be described later with reference to FIG. The operation determination unit 6 determines the operation state of operation members such as a release button, a zoom button, a reproduction button, and a menu button provided on the camera 10. In the menu mode, various modes such as a moving image shooting mode, a still image shooting mode and the like can be set.

  The clock unit 9 outputs date and time information. The recording unit 4 is a recording medium for recording image data. When the image processing and control unit 1 determines that the operation of the image capturing instruction has been made by the operation determination unit 6, the image processing and control unit 1 records image data and shooting date and time information in the recording unit 4 in association with the image data. This is to enable image management based on shooting date and time.

  The display unit 8 is configured by a display device such as a liquid crystal monitor disposed on the back surface of the camera 10 or the like. In addition, the display unit 8 can display a subject image in a live view as a moving image based on the image data from the imaging unit 2 and can reproduce a photographed image recorded in the recording unit 4. A touch panel 8 b is disposed on the surface of the display unit 8 and can detect a touch of a finger of the photographer or the like. When the menu mode is set, a menu screen is displayed on the display unit 8 and can be set by touching the displayed menu, for example, moving image shooting, still image shooting, and the like. In addition, when the reproduction mode is selected, it is also possible to enlarge and display a desired image by touching among the photographed images displayed in a list. The details of the touch panel 8b will be described later with reference to FIG.

  Next, the tilt detection unit 7 that detects the tilt state of the camera 10 will be described with reference to FIG. Although there are various sensors for detecting the inclination, one example shown in FIG. 2 is such that permanent magnets are always directed in the direction of gravity, and the magnets are detected by a Hall element. That is, the permanent magnet 7b is supported by the support arm 7c, and the support arm 7c is rotatable around the shaft 7d. The permanent magnet 7b pivots around an axis 7d so as to face in the direction of gravity. A Hall element 7a is disposed in the rotational path of the permanent magnet 7b, and the Hall element 7a detects a change in the magnetic field of the permanent magnet 7b.

  When the posture of the camera 10 is in the horizontal state (horizontal composition posture), the permanent magnet 7b is in the position as shown in FIG. 2 (a), and when it is tilted, as shown in FIG. 2 (b) 7b tilts. By detecting the tilt state of the permanent magnet 7b by the Hall element 7a, it is possible to detect the attitude of the camera 10, and to determine whether the attitude of the camera 10 is in the vertical composition or in the horizontal composition.

  Next, the acceleration detection unit 5 for detecting the acceleration applied to the camera 10 will be described with reference to FIG. The acceleration sensor 50 is comprised from the metal part 52 of the chip | tip surface, and the bridge | crosslinked metal part 51, as shown to Fig.3 (a). The metal portion 51 includes four base points 51a, an H-shaped bridge portion 51b held by the base points 51a, and a detection portion 51c facing the metal portion 52. The acceleration sensor 50 detects the capacitance of a capacitor formed by the detection unit 51 c and the metal unit 52. When the metal portion 51 moves in the direction of arrow A in FIG. 3, the capacitance of the capacitor changes. Therefore, the acceleration in the direction of arrow A can be detected by obtaining the amount of change.

  Further, as shown in FIGS. 3B and 3C, the detection output of the acceleration sensor 50 differs depending on the direction of the applied acceleration. That is, as shown in FIG. 3 (b), the positive output changes first and then the negative output, and as shown in FIG. 3 (c), the negative output changes first after the negative output. In this case, the direction of acceleration is different. For this reason, the direction of the acceleration is also known by detecting the change in the signal.

  The aforementioned acceleration sensor 50 is disposed at three places on the camera 10, as shown in FIG. 3 (d). That is, an acceleration sensor 50X that detects acceleration in the longitudinal direction (X direction) of the camera 10, an acceleration sensor 50Y that detects acceleration in the Y direction orthogonal to the longitudinal direction of the camera 10, and a left side of the camera 10 and an optical axis An acceleration sensor 50Z that detects an acceleration in a direction (Z direction) is disposed to detect an acceleration along each direction.

  Next, the structure of the touch panel 8b is shown in FIG. The touch panel 8 b is a photoelectric sensor type touch panel. In the touch panel 8b, as shown in FIG. 4A, the photosensors 80b are two-dimensionally arranged at predetermined intervals in the liquid crystal 80, and the back light 80a is provided on the back surface of the liquid crystal 80. . The photoelectric sensor type touch panel is not disposed on the liquid crystal, but integrally incorporated in the liquid crystal. As the touch panel, other than the photoelectric sensor type, another touch panel such as a resistive film type may be used.

  When the user's finger 81 approaches the touch panel 8b, as shown in FIG. 4B, the light from the backlight 80a is reflected by the finger 81 and detected by the light sensor 80b. The touch position can be detected depending on which light sensor 80 b detects the reflected light from the finger 81.

  Next, how to turn on the power at the start of shooting in the present embodiment will be described with reference to FIG. FIG. 5A shows a state in which the photographer 15 holds the camera 10 to take a picture. In this case, the camera 10 is held horizontally (horizontal composition posture), the photographing lens 2b is directed to the object side, and the back side of the camera 10 is directed to the photographer 15. At this time, as shown in the figure, the X direction, the Y direction, and the Z direction are the same as the longitudinal direction of the camera 10, the Y direction is orthogonal to the longitudinal direction, and the centroid direction, and the Z direction Is the optical axis direction of the photographing lens 2b.

  In the state where the camera 10 shown in FIG. 5A is held, when the photographer 15 moves back and forth so as to bow the camera 10, in the present embodiment, the power of the camera 10 is turned on. That is, when the camera 10 is first turned to the front side and then the camera 10 is returned to the original position, the motion at this time is detected by the acceleration detection unit 5 and the power of the camera 10 is turned on based on the detection result.

  FIG. 6 shows time changes of detection outputs of the acceleration sensors 50X, 50Y and 50Z of the acceleration detection unit 5. As shown in FIG. When the photographer 15 holds the camera 10, the acceleration sensor 50Y receives the influence of gravity and outputs a detection signal of about 1 G, and the other acceleration sensors 50X and 50Z have almost zero detection signals, and any detection signal is Signals from camera shake are superimposed.

  When the photographer 15 turns the camera 10 to the front side at the timing of time t1, as shown in FIG. 6, the detection output of the acceleration sensor 50Z rapidly increases and becomes a value approximately equivalent to 3G. In addition, the detection output of the acceleration sensor 50Y sharply decreases. Then, at time t2, when the photographer 15 holds the camera 10 by returning the inclination, the detection output of the acceleration sensor 50Z once decreases to the minus side, and then returns to the original level. In addition, the detection output of the acceleration sensor 50Y once increases to a value equivalent to approximately 3 G, and then returns to a value equivalent to approximately 1 G which is the original level.

  Thus, by detecting the signal change of the acceleration sensors 50Y and 50Z, it can be determined whether or not the camera 10 falls from the holding state to the front side and then returns to the original holding position. It becomes possible. In the present embodiment, power supply to the comparator 5a of the acceleration detection unit 5 is continued even in the power-off state. Then, when an acceleration signal equivalent to approximately 3 G generated when the camera 10 is tilted, a signal is output from the comparator 5a to the image processing and control unit 1, and the second power control unit 1b detects the gravity determination unit 1d and the acceleration. Power is supplied to the entire detection unit 5. The gravity determination unit 1d finely detects a change in acceleration, determines the movement of the camera 10, and determines whether to turn on the power.

  Next, the power-on operation in the present embodiment will be described using the flowchart shown in FIG. Of the flow shown in FIG. 7, steps S101 and S102 are not performed by the image processing and control unit 1, but are performed in hardware. First, the acceleration sensor is set to the comparator mode, and the sensor is initialized (S101). In this step, when the power is turned off, power is supplied to the comparator 5a in the acceleration detection unit 5, and the comparator 5a sets a comparator mode to compare the detection signal of the acceleration sensor 50 with the determination value.

  Subsequently, it is determined whether or not the gravity amplitude of Z is large (S102). Here, it is determined by the comparator 5a whether the acceleration signal output from the acceleration sensor 50Z is at a level exceeding approximately 3G. As a result of this determination, if the amplitude is not large, the process returns to S101.

  If the result of the determination in step S102 is that the amplitude is large, then the power is slightly increased and the acceleration is finely detected (S103). Here, power supply to the entire acceleration detection unit 5 and the gravity determination unit 1 d is started by the second power supply control unit 1 b. That is, in step S102, it is only understood that an acceleration exceeding approximately 3 G is applied, and the change in the value of the acceleration is unknown, so the AD conversion unit of the gravity determination unit 1d finely detects the acceleration. .

  When the acceleration is finely detected, next, it is detected whether or not the gravity of Z which has been applied previously decreases (S104). As can be seen from the graph of signal change shown in FIG. 6, when the camera 10 is turned forward at timing t1, the signal output of the acceleration sensor 50Z increases, and when it reaches a peak, it turns to decrease. In this step S104, the signal output of the acceleration sensor 50Z is AD converted, and it is determined whether or not the peak is exceeded.

  As a result of the determination in step S104, if not decreasing, it is determined whether a predetermined time has elapsed (S121). Here, in step S102, it is determined whether or not a predetermined time has passed since the detection of the large gravity amplitude of Z. This predetermined time is set to, for example, about 1 second, which is sufficient for the photographer 15 to tilt the camera 10 forward. While waiting for the predetermined time to elapse, if the gravity does not decrease during that time, it is determined that the photographer 15 has not performed the power on operation, and the process returns to step S101 to return to the power off state.

  As a result of the determination in step S104, if the gravity decreases, it is next determined whether the gravity of Y is approximately 1 G (S105). Here, the signal output from the acceleration sensor 50Y is AD converted, and it is determined whether the value is approximately equivalent to 1 G. As shown in FIG. 6, at timing t2, the camera 10 is returned to the original posture (held posture), and when it settles down, the value of the acceleration sensor 50Y corresponds to approximately 1 G. This step S105 is a determination as to whether or not the camera is returned to the ready state.

  As a result of the determination in step S105, when it is not about 1 G, it is determined whether a predetermined time has elapsed (S105). Here, in step S104, the clocking operation is started from the time when the gravity decreases in Z, and it is determined whether a predetermined time has elapsed. The predetermined time is, for example, about 1 second, which is sufficient for returning the camera 10 which has been turned to the front side. While waiting for the predetermined time to elapse, if the gravity does not decrease during that time, it is determined that the photographer 15 has not performed the power on operation, and the process returns to step S101 to return to the power off state.

  As a result of the determination in step S105, when the gravity of Y reaches about 1 G, next, power increase 1 is performed to turn on the touch panel (S111). Here, the third power control unit 1c supplies power to the touch panel 8b, and detects a touch signal from the touch panel 8b. Further, the power supply to the imaging system is started by the first power control unit 1c, and the imaging operation is started. In this embodiment, in changing the focal length, it is assumed that there is no movable part such as a zoom lens whose outer shape changes, and the zoom position has a wide angle of view on the wide side. , It is desirable that the focus be initialized to the normal focus position.

  Subsequently, it is determined whether the camera 10 is correctly held (S112). Here, it is determined whether the photographer 15 holds the camera 10. This is because the power consumption is consumed even if the power is turned on if the cameraman 15 does not properly hold the camera 10 simply by moving the camera 10 back and forth. The determination as to whether or not the user is correctly holding will be described later with reference to FIG.

  As a result of the determination in step S112, if the user is not holding properly, it is determined whether a predetermined time has elapsed (S113). Here, in step S105, the clocking operation is started from the time when the gravity of Y becomes equivalent to 1 G, and it is determined whether a predetermined time has elapsed. The predetermined time is a time sufficient for correctly holding the camera 10 from the restored state, for example, about 5 seconds from holding with the right hand to attaching the left hand. After waiting for the predetermined time to elapse, if the camera is not properly held even after the predetermined time has elapsed, the imaging is turned off (S114). Here, the power supply to the imaging system is turned off by the first power control unit 1a. When the imaging is turned off, the process returns to step S101 to return to the power-off state.

  As a result of the determination in step S112, if the camera is correctly held, power increase 2 is performed, the display is turned on, and the power is turned on (S115). By performing the power increase 2, the camera 10 is turned on, and the normal camera operation can be performed.

  As described above, even in the power-off state, the power-on flow in the present embodiment supplies power to the comparator 5 a of the acceleration detection unit 5 and performs an intentional operation by the photographer 15, ie It can be judged. When the detection signal is output from the comparator 5a, the output signal of the acceleration detection unit 5 is AD converted, the movement is finely detected, the movement of the camera 10 is determined, and the intentional operation by the photographer 15; When it is determined that the camera 10 is turned forward and then returned to the original holding position, the power is turned on.

  After the camera 10 is moved forward, the movement to return to the original position does not occur in daily life unless the photographer 15 intentionally performs it. Therefore, in the present embodiment, it is possible to prevent a malfunction in which the power is turned on from the power off state.

  Further, in the present embodiment, even if it is detected that the camera has been returned to the original position after having been knocked forward, it is further judged whether or not the user is properly holding the hand (see S112). Can be prevented.

  In this embodiment, although the gravity amplitude of Z is detected in step S102, the comparator 5a is not a type that detects only the Z direction, but is a type that detects all the directions of the X, Y, and Z directions. Even in the case of In this case, the amplitude in all directions of X, Y, and Z is detected, but in step S103, the acceleration may be detected in each direction and determined in step S104.

  In addition, in the present embodiment, when it is detected in step S105 that the gravity of Y has become about 1 G, it is further determined in step S112 whether or not the user is properly holding the camera. However, when the gravity of Y reaches about 1 G, the photographer 15 turns the camera 10 forward and sets the original position, that is, the state of holding, so at this point, the power increase 2 is immediately performed, The display may be on and the shooting state may be set.

  Next, the determination as to whether or not the camera is held in step S112 will be described using FIG. When the flow shown in FIG. 8A is entered, it is first determined whether it is a horizontal composition (S201), and if it is not a horizontal composition, it is determined whether it is a vertical composition (S202). Whether horizontal composition or vertical composition is determined based on the output of the acceleration detection unit 5. In addition to the acceleration detection unit 5, for example, a gravity detector or the like may be provided to make a determination using this output.

  If it is determined Yes in step S201 or step S202, that is, if it is a horizontal composition or a vertical composition, it is next determined whether or not vibration is for 1 second (S203). In this step, based on the detection output of the acceleration detection unit 5, it is determined whether or not vibration has occurred for one second. Note that one second is an example, and this time may be longer or shorter than this, and it is sufficient if there is no vibration during the time when it can be said that the camera is correctly held.

  As a result of the determination in step S203, if there is no vibration for one second, it is next determined whether the predetermined position is touched (S204). In this step, the determination is made based on the detection output from the touch panel 8b. In the case of the horizontal composition, as shown in FIG. 8B, since the upper right is held, it is determined whether or not there is a detection output corresponding to this portion. Also in the case of the vertical composition, since this portion is held, the determination is similarly performed based on the detection output of the touch panel 8b.

  When the predetermined position is touched as a result of the determination in step S204, it is determined as Yes. That is, in this case, it is determined that the camera is properly held since there is no vibration for a predetermined time in the horizontal composition or the vertical composition and the photographer holds the predetermined position. On the other hand, if the result of the determination in step S202 is that the horizontal composition is not a vertical composition, or if there is vibration in step S203 or if the predetermined position has not been touched as a result of the determination in step S204, No judgment is made. In this case, the camera is not properly held.

  As described above, in the flow illustrated in FIG. 8A, it can be determined whether the camera is held firmly and held. As described above, in the power-on flow, when the camera is held, the display is turned on and the normal camera operation mode is started.

  As described above, in the first embodiment of the present invention, the acceleration detection unit constantly determines the output of gravity or more, and when the output of gravity or more is detected (S102 → Yes), When the posture change in the up and down direction when holding the camera while looking at the display unit 8 is detected (S104 → Yes, S105 → Yes), the power is turned on (power increase 1). For this reason, the power is turned on only by the operation when holding the hand, and in other states, the power is not turned on by a malfunction. That is, the power can be turned on only by performing posture change in the vertical direction of the camera when holding the camera, and this posture change does not occur in normal daily operation. Moreover, since these operations are performed within a predetermined time, it is considered that the intention of the photographer is reflected. Since such an operation is detected, the power is not turned on due to a malfunction. In the present embodiment, it is determined whether or not it is within the predetermined time. However, the present invention is not limited to this, and a determination may be added to make the motion faster than the predetermined time unnatural.

  Next, a second embodiment of the present invention will be described using FIG. 9 to FIG. In the first embodiment, the power is turned on when it is detected that the camera 10 is turned down from the position where the camera 10 is held and then returned to the original position. In the second embodiment, the power is turned on when it is detected that the camera 10 is tilted sideways from the position at which the camera 10 is held and not to the front and then returned to the original position. The configuration in the second embodiment is the same as that of FIG. 1 of the first embodiment, and only the flow shown in FIG. 7 is replaced with the flowchart shown in FIG. The differences will be mainly described.

  FIG. 9 shows how to power on the camera 10 in the second embodiment. FIG. 9 (a) is similar to FIG. 5 (a), and shows the photographer 15 holding the camera 10 to take a picture. When the photographer 15 reciprocates the camera 10 one time to the left and right while holding the camera 10 shown in FIG. 9A, the power of the camera 10 is turned on. That is, when the camera 10 is first tilted left or right and then the camera 10 is returned to its original position, the motion at this time is detected by the acceleration detection unit 5 and the power of the camera 10 is detected based on the detection result. Turn on.

  FIG. 10 shows a time change of detection outputs of the acceleration sensors 50X, 50Y and 50Z of the acceleration detection unit 5. When the photographer 15 holds the camera 10, as in the first embodiment, the acceleration sensor 50Y is affected by gravity and outputs a detection signal of about 1 G, and the other acceleration sensors 50X and 50Z have almost zero. In each of the detection signals, signals due to camera shake are superimposed.

  When the photographer 15 tilts the camera 10 to the left or right at time t11, as shown in FIG. 10, the detection output of the acceleration sensor 50X rapidly increases to approximately a value equivalent to 3G. In addition, the detection output of the acceleration sensor 50Y sharply decreases. Then, at time t13, when the photographer 15 holds the camera 10 by returning the inclination, the detection output of the acceleration sensor 50X once decreases to the minus side and then returns to the original level. In addition, the detection output of the acceleration sensor 50Y once increases to a value equivalent to approximately 3 G, and then returns to a value equivalent to approximately 1 G which is the original level.

  As described above, by detecting the signal change of the acceleration sensors 50X and 50Y, it is determined whether the camera 10 is tilted from the holding state to the left or right and then returns to the original holding position. It becomes possible.

  Next, the power on operation in the second embodiment of the present invention will be described using the flowchart shown in FIG. The power-on flow chart is different from the power-on flow chart in the first embodiment shown in FIG. 7 except that step S102 is replaced with S102 b, step S104 with S104 b, step S111 with S111 b, and step S112 with S112 b. Are the same, so we will focus on this difference.

  When the power-on flow is entered and the acceleration sensor is set to the comparator mode (S101), it is next determined whether or not the gravity amplitude of X is large (S102b). Here, it is determined whether the output of the acceleration sensor 50X has exceeded a value equivalent to approximately 3G. As described with reference to FIG. 10, when the camera 10 is tilted to the right or left, the acceleration in the X direction increases, so the determination here is that the photographer 15 has tilted the camera to turn on the power. It is.

  As a result of the determination in step S102b, if the gravity amplitude of X is large, then the acceleration is finely detected (S103), and it is determined whether the gravity of X is decreasing (S104b). In this step, the signal output of the acceleration sensor 50X is AD converted, and it is determined whether this value tends to decrease. When the camera 10 is tilted to the right or left and returned to the original position again, the signal output of the acceleration sensor 50X peaks and then decreases, so in this step it is determined whether the peak has passed.

  As a result of the determination in step S104b, if the gravity of X decreases, it is next determined whether the gravity of Y has become approximately 1 G (S105). If the result of this determination is approximately 1 G, then the imaging system is turned on (S111 b). If it is approximately 1 G, since the original position, that is, the position where the camera 10 is held is returned, in this step, the power supply is supplied to the imaging system by the first power control unit 1a.

  If the imaging system is turned on, it is next determined whether or not it is appropriate for imaging (S112b). As determination as to whether imaging is appropriate, for example, based on image data from the imaging unit 2, it is determined whether the surrounding area is dark. In the case of being in a bag or a case, the surroundings are dark, and in such a case, it is determined that it is not suitable for shooting.

  If the result of determination in step S112 b is that it is appropriate for shooting, power increase 2 is performed and the display is turned on (S115). By performing the power increase 2, the camera 10 is turned on, and the normal camera operation can be performed.

  As described above, in the flow of power on in this embodiment, as in the first embodiment, power is supplied to the comparator 5 a of the acceleration detection unit 5 even in the power off state, and the intentional operation by the photographer 15 is performed. In the present embodiment, it is possible to determine whether the left or right side is tilted. When the detection signal is output from the comparator 5a, the output signal of the acceleration detection unit 5 is AD converted, the movement is finely detected, the movement of the camera 10 is determined, and the intentional operation by the photographer 15; When it is determined that the camera 10 is tilted and then returned to the original holding position, the power is turned on.

  After the motion to tilt the camera 10, the motion to return to the original position does not occur in daily life unless the photographer 15 intentionally performs the motion. Therefore, in the present embodiment, it is possible to prevent a malfunction in which the power is turned on from the power off state.

  Further, in the present embodiment, even when it is detected that the lens is returned to the original position after being tilted, it is further determined whether or not it is suitable for photographing (see S112 b), so that malfunction is further prevented. can do.

  Next, power off in the present embodiment will be described using the flowchart shown in FIG. When the photographer 15 tilts the camera 10, the power is turned off. That is, power off can be performed by tilting the camera 10 as in the case of power on.

  First, the shooting mode is executed (S501). Here, when the subject image is observed by the display unit 8 and the composition is determined, the image data is recorded in the recording unit 4 by the release operation. When the imaging mode is executed, it is determined at a predetermined timing whether or not the gravity amplitude of X is large (S502). Here, the signal output of the acceleration sensor 50X is AD converted, and the gravity determination unit 1d determines whether the amplitude has become large. As a result of this determination, if the value does not increase, the process returns to step S501, and the shooting mode is continued.

  On the other hand, when the gravity amplitude of X becomes large as a result of the judgment in step S502, next, it is judged whether the gravity of X decreased (S503). As described above, when the camera 10 is tilted from the holding position to either left or right and returned to the original position, the signal output of the acceleration sensor 50X increases and then decreases. In these steps S502 and S503, it is determined whether it is tilted left or right to return to the original position.

  As a result of the determination in step S503, when the gravity of X does not decrease, it is next determined whether a predetermined time has elapsed (S504). Here, in step S502, it is determined whether a predetermined time has elapsed since the gravity amplitude of X became large. The predetermined time is a time sufficient to tilt the camera 10 to either the left or the right. While waiting for the predetermined time to elapse, while the gravity does not decrease, it is determined that the photographer 15 has not performed the power-off operation, the process returns to step S501, and the imaging mode is continued.

  As a result of the determination in step S503, if the gravity of X decreases, it is next determined whether the gravity of Y has become approximately 1 G (S505). As a result of this determination, if it is not about 1 G, it is determined whether a predetermined time has elapsed (S506). Here, in step S503, time is measured from the time when the gravity of X decreases. The predetermined time is a time sufficient to once return to the left or right and then return to the original position. It is determined whether or not the gravity of Y has become approximately 1 G until the predetermined time has elapsed, and when the predetermined time has elapsed without becoming approximately 1 G, the process returns to step S501, and the imaging mode is continued. This is because it is determined that the photographer 15 has not performed the operation for turning off the power.

  As a result of the determination in step S505, when the gravity of Y becomes about 1 G, the imaging and display are turned off, and the power is turned off (S507). When the power is turned off, the power supply is stopped except for the comparator 5a and the like, and the consumption of the power battery is prevented.

  As described above, in the power-off flow, the power of the camera 10 can be turned off by tilting the camera 10 to either the left or right as in the power-on. For this reason, it is possible to omit turning off the power switch, and the power can be turned off immediately.

  As described above, also in the second embodiment of the present invention, as in the first embodiment, the acceleration detecting unit constantly determines the output more than gravity, and detects the output more than gravity. (S102b-> Yes) When the posture change in the up and down direction when holding the camera while looking at the display unit 8 is detected (S104b-> Yes, S105-> Yes), the power is turned on (power increase 1). For this reason, the power is turned on only by the operation (tilted to either the left or right) when holding the hand, and in the other state, the power is not turned on due to a malfunction. That is, the power can be turned on only by performing posture change in the vertical direction of the camera when holding the camera, and this posture change does not occur in normal daily operation, and these operations are performed within a predetermined time. It is considered that the intention of the photographer is reflected, and the power is not turned on due to a malfunction. Also in the present embodiment, as in the first and second embodiments, it is determined whether or not it is within the predetermined time, but the present invention is not limited thereto, and the determination to make the motion faster than the predetermined time unnatural is added You may.

  Next, a third embodiment of the present invention will be described using FIG. 13 to FIG. In the first and second embodiments of the present invention, the imaging system is turned on and the photographer operates the release button when taking a specific action such as tilting it forward or tilting it to the left or right. Was able to do. In this embodiment, the continuous shooting or the continuous shooting is started at the time of tilting to the left and right and returning to the original position. The configuration of this embodiment is the same as that of FIG. 1 of the first embodiment, and only the flow shown in FIG. 7 is replaced with FIG. Therefore, the differences will be mainly described.

  In the present embodiment, in the operation in the second embodiment shown in FIG. 9, the operation for turning on the power is performed by tilting the power supply to either left or right and turning the power on at the timing of returning. That is, in the waveform of the acceleration detection signal shown in FIG. 10, when timing t12 at which the acceleration sensor 50X turns from increase to decrease is detected, the power is turned on at this time (power increase 2) to supply power to the imaging system. Also, imaging is started from this timing t12.

  The operation of the camera 10 of the present embodiment will be described using the flowchart shown in FIG. In the power-on flow in this embodiment, as in the second embodiment, first, the acceleration sensors 50X to 50Z are set to the comparator mode, and the sensors are initialized (S101). Subsequently, it is determined whether or not the gravity amplitude of the acceleration sensor 50X is large (S102b). As a result of this determination, if the gravity amplitude is not large, the process returns to step S101. Steps S101 and S102b are implemented in hardware as in the first and second embodiments.

  If the gravity amplitude of the acceleration sensor 50X is large as a result of the determination in step S102b, then the acceleration is finely detected (S103). Here, as in the first and second embodiments, the gravity determination unit 1d detects the acceleration based on the signal output from the acceleration sensor 50X. Subsequently, it is determined whether or not the gravity of X has started to decrease (S107). Here, it is determined whether the signal output of the acceleration sensor 50X starts to decrease. The position where the decrease starts corresponds to the position where the left or right side is inclined and the maximum inclination angle is left.

  If it is determined in step S107 that the gravity of X has not decreased, it is next determined whether a predetermined time has elapsed (S121). Here, it is determined whether or not a predetermined time has elapsed from the timing when the gravity amplitude of X is determined to be large in step S102b. As the predetermined time, normally, when the camera 10 is inclined to either the left or right, it is sufficient time to reach the maximum inclination angle. If it is determined in step S121 that the predetermined time has not elapsed, the process returns to step S107. If the predetermined time has elapsed, the process returns to step S101, and the power is turned off.

  As a result of the determination in step S107, when the gravity of X starts to decrease, next, the imaging system is turned on, continuous shooting is started, and tilt correction information is recorded (S108). Here, power is supplied to the imaging system by the first power control unit 1a (power increase 2), continuous shooting is started by the imaging unit 2, and the image data of the continuous shooting is related to the inclination acquired from the acceleration detection unit 5 Record tilt correction information.

  When continuous shooting and the like are started, it is next determined whether or not there is gravity in X for a predetermined time (S109). Here, since the camera 10 is inclined to the left or right and the tilt angle is the highest, it is determined whether or not there is a signal output corresponding to gravity from the acceleration sensor 50X even after a predetermined time has elapsed. As a result of this determination, if there is gravity even after X has passed a predetermined time, then the imaging is turned off (S110). In this case, since the camera 10 is only tilted left or right and the photographer does not intentionally turn on the power, imaging is turned off. When the imaging is turned off, the process returns to step S101, and the power is turned off.

  On the other hand, as a result of the determination in step S109, if there is no gravity in X after a predetermined time has elapsed, it is next determined whether there is no gravity in the Z direction (S116). Here, the determination is made based on the signal output of the acceleration sensor 50Z. If the result of this determination is that there is gravity in the Z direction, continuous shooting is continued and the old image is deleted (S117). Since it is detected that there is no acceleration corresponding to gravity in the X direction in step S109 and no acceleration corresponding to gravity in the Z direction in step S116, in this case, the camera 10 is in the original holding position I'm back. In this case, the continuous shooting started in step S108 is continued, and when the memory capacity is over, the old image is erased. Subsequently, as in the first and second embodiments, the display is turned on.

  On the other hand, if the result of determination in step S116 is that there is an acceleration equivalent to gravity in the Z direction, the mode is switched to the playback mode, and the continuous shooting result is deleted (S118). The gravity in the Z direction is a state in which the photographer tilts the camera 10 forward and looks at the display unit 8. Therefore, while switching to the playback mode, the continuous shooting result is erased, and the process returns to step S109.

  The above power-on operation will be described with reference to FIGS. 14 to 16. FIG. 14 shows a state in which the camera 10 is turned to either the left or the right and the power is turned on to watch continuous shooting in an athletic meet or the like. FIG. 14 (a) shows how the camera 10 starts to be returned from the most inclined state and begins to return to the original position sequentially as in FIGS. 14 (b) and (c). d) is back to the horizontal position.

  As described above, continuous shooting is started in step S108, and continuous shooting is performed as shown in FIGS. 14 (a) to 14 (d) at the camera angle of view 21 at that time. In the method of turning on the power of the camera by a specific operation such as tilting, when starting an operation such as tilting, there is a high possibility that the subject is already directed. Therefore, at timing t12 in FIG. 10, that is, imaging is started at the turning position of the operation such as tilting, and both the imaging result and the inclination are recorded.

  In order to start recording as soon as possible, in step S107, imaging is started when detection of the start of gravity decrease of X is detected. At this time, power supply to the display unit 8 may be started so that a subject image is displayed. Further, it is desirable that the focal length of the photographing lens 2b be initially set at the wide end and the focal position be approximately 2 to 3 m so that the main subject is immediately captured and the main subject enters the screen.

  In addition, in order to avoid useless energy loss, it is made not to perform strobe light emission or the like. However, if it is determined in step S116 that there is gravity in the Z direction, as shown in FIG. 16, the camera 10 is tilted to the front side, and the photographer is going to view the photographed image on the display unit 8. In this case, the mode is switched to the reproduction mode (see S118).

  When imaging is ended by the operation of the release button or the like, the camera 10 aligns the parts of the same face, trims the parts, and generates a series of continuous images. That is, from the image of the camera angle of view 21, a portion including the same face (portion of trimming 23) is extracted. In the extraction, the inclination of the image is corrected using the inclination correction information recorded together with the image data at the time of photographing.

  FIG. 15 is a series of continuous images generated in this manner. FIG. 15 (a) corresponds to the trimming 23 of FIG. 14 (a), where the portion without an image is blacked out. Similarly, FIG. 15B corresponds to the trimming 23 in FIG. 14B, FIG. 15C corresponds to the trimming 23 in FIG. 14C, and FIG. 15D corresponds to the trimming 23 in FIG. . This series of continuous images may be reproduced as a moving image or as a still image.

  As described above, also in the third embodiment of the present invention, in the same manner as in the first and second embodiments, the acceleration detecting unit constantly determines the output more than gravity, and detects the output more than gravity. (S102b: Yes) If the posture change in the vertical direction when holding the camera while looking at the display unit 8 of the camera is detected (S107: Yes), the power is turned on (power increase 2). Further, since these operations are performed within a predetermined time (S121 → Y), it is considered that the intention of the photographer is reflected. For this reason, the power is turned on only by the action (tilting to either the left or right) when holding. Also in the present embodiment, as in the first and second embodiments, it is determined whether or not it is within the predetermined time, but the present invention is not limited thereto, and the determination to make the motion faster than the predetermined time unnatural is added You may.

  Further, in the third embodiment, not only the power is turned on simply by holding and tilting the camera 10, and shooting is also started, so there is no possibility of missing the subject. Further, in the present embodiment, since the image is taken when returning from the inclined state, the image is inclined and unsightly as it is, but the tilt correction information is recorded at the time of shooting, and correction is performed using this tilt correction information. Therefore, such problems can be eliminated.

  Next, a fourth embodiment of the present invention will be described using FIG. 17 and FIG. In the first and second embodiments, when the photographer 15 performs an operation that can not normally occur from the position at which the camera 10 is held, the power is turned on. In the fourth embodiment, the photographer 15 performs an operation that can not normally occur from the position at which the camera 10 is held, and when the operation mode is selected on the display screen, the power is turned on. The configuration in the fourth embodiment is the same as that of FIG. 1 of the first embodiment, and only the flow shown in FIG. 7 is replaced with the flowchart shown in FIG. The differences will be mainly described.

  FIG. 17 shows how to power on the camera 10 in the fourth embodiment. FIG. 17A shows a state in which the camera 10 is shaken to the left and right in a state where the photographer 15 holds the camera 10 for shooting. In the second embodiment, only one reciprocation is performed to the left and right, but in the fourth embodiment, the oscillation may be performed once or plural times. When the camera 10 is returned to the position where the camera 10 is held as shown in FIG. 17B, the display unit 8 of the camera 10 displays a moving image shooting mode, playback mode, stillness as shown in FIGS. 17C and 17D. An image shooting mode and three operation modes are displayed.

  When the three operation modes are displayed, the photographer 15 touches one of the operation modes with a finger, and detects this with the touch panel 8b. FIG. 17 (c) shows a state in which still image shooting is touched with the finger of the right hand, and FIG. Since moving pictures often hold the camera 10 firmly with both hands and often hold the camera 10 with one hand, the positions of moving picture shooting and still shooting are arranged as shown in FIG. 17 (c) (d). did.

  Next, the power-on operation in the fourth embodiment of the present invention will be described using the flowchart shown in FIG. Compared with the power-on flow chart of the first embodiment shown in FIG. 7, the power-on flow chart replaces step S102 with S102 b, step S104 with S104 c, step S111 with S111 c, and step S112 with S112 c. The difference between step S104 and step S111 is the same except that it is changed as shown in the figure, so this difference will be mainly described.

  In the power-on flow, when the acceleration sensor is set to the comparator mode (S101), next, as in the second embodiment, it is determined whether or not the gravity amplitude of X is large (S102b). Here, it is determined whether the output of the acceleration sensor 50X has exceeded a value equivalent to approximately 3G. Since the acceleration in the X direction increases when the camera 10 is shaken, the determination here is whether or not the photographer 15 has shaken the camera to turn on the power.

  As a result of the determination in step S102b, when the gravity amplitude of X is large, next, the acceleration is finely detected (S103), and it is determined whether or not gravity of approximately 1 G is applied to Y (S104c) ). In this step, the signal output of the acceleration sensor 50Y is AD converted, and it is determined whether or not this value becomes approximately 1G. While the camera 10 is being shaken, the signal output of the acceleration sensor 50Y greatly changes, and does not stabilize at about 1 G. As a result of the determination in step S104c, when Y is not approximately 1 G, the process returns to step S101, and the power is turned off.

  As a result of the determination in step S104c, when the gravity of Y is approximately 1 G, it is next determined whether a predetermined time has elapsed (S121). Here, in step S104c, it is determined whether a predetermined time has elapsed since time when Y became 1G. In addition, as predetermined time, it is the time of the grade which can be considered that the state which hold | maintained from the state waved was stabilized.

  If it is determined in step S121 that the predetermined time has not elapsed, the process returns to step S104c. On the other hand, when the predetermined time has elapsed, the power is increased 1 to turn on the display system and the touch panel (S111c). Here, since it is stable when the camera 10 is in a holding state, the display unit 8 displays three operation modes such as the operation photographing as described above, and the touch panel 8b starts detection of a touch state.

  Subsequently, it is determined whether or not the touch is made (S112 c). Here, it is determined whether the display unit 8 is touched by the touch panel 8b. As a result of this determination, if it is not touched, it is next determined whether a predetermined time has elapsed (S113). Here, in step S111 c, clocking is performed from the time when the power increase 1 is performed, and it is determined whether or not a predetermined time has elapsed. If it is determined that the predetermined time has not elapsed as a result of this determination, the process returns to step S112c. As a result of this determination, when a predetermined time has elapsed, the process returns to step S101, and the power is turned off.

  As a result of the determination in step S112c, when the touch is performed, the power increase 2 is performed, and activation is performed in the touched mode (S116). That is, the power is turned on. By performing the power increase 2, the camera 10 is turned on, and the normal camera operation can be performed.

  As described above, also in the fourth embodiment of the present invention, as in the first and second embodiments, the acceleration detecting unit constantly determines the output more than the gravity, and the detection signal is output from the comparator 5a. The output signal of the acceleration detection unit 5 is A / D converted to finely detect the movement. When it is detected that the camera 10 has become stable, the operation mode is displayed, and when the photographer selects the operation mode, the power is turned on. In the present embodiment, as in the first and second embodiments, the verification of the tilting operation to the front and back or the tilting operation to the left and right is not carefully performed, but before the power is turned on, the operation by the photographer Since the mode is selected, there is no risk that the power will be turned on due to a malfunction. Also in the present embodiment, as in the first to third embodiments, it is determined whether or not it is within the predetermined time (S121 → Yes), but it is not limited to this and motion faster than the predetermined time is unnatural You may add a decision to make it.

  As described above, in each of the embodiments of the present invention, the power of the camera is turned on when the output above gravity is detected and it is detected that the camera has performed a specific movement. For this reason, the power is turned on only by the operation when holding the hand, and in other states, the power is not turned on by a malfunction.

  That is, the power consumption is extremely small only by determining whether or not there is a vibration above gravity, and it can be said that the power is substantially off. On the other hand, in the conventional sleep mode, the power consumption is greater than this and the power is consumed, and in some cases, the shutter chance may be missed. As described above, in an extremely low power consumption state, the power can be turned on immediately by holding the camera and performing a specific movement. Also, when the power is turned on, the movement of the camera is determined, and usually the power is turned on only when a specific movement that is not performed is performed.

  In each embodiment of the present invention, as a specific movement, the camera is tilted forward and then returned to the original position (first embodiment), or the camera is tilted left or right (first Three embodiments) Four examples in the case where the camera is shaken (the fourth embodiment) in the case where it is returned to the original position after being inclined left or right and then returned to the original position (the fourth embodiment) have been described. However, the movement is not limited to this, and any movement that does not occur in normal daily operation may be used.

  In each embodiment of the present invention, an acceleration sensor has been described as an example of a sensor for detecting the movement of the camera. However, the present invention is not limited to this, and any sensor that can detect the motion of the camera, such as an angular acceleration sensor or a gyro, can be applied.

  Furthermore, in each embodiment of the present invention, power is supplied to some circuits and the like, such as the acceleration detection unit 5, the gravity determination unit 1d, and the touch panel 8b before the power is turned on. The circuit for supplying power during the period from the power-off state to the power-on is not limited to the circuit described above, and may be appropriately selected in accordance with the determination condition as to whether or not the power is turned on.

  Furthermore, in each of the embodiments of the present invention, although the digital camera has been described as an apparatus for photographing, the camera may be a digital single-lens reflex camera or a compact digital camera, such as a video camera or a movie camera. It may be a camera for moving images, or may be a camera built in a mobile phone, a personal digital assistant (PDA), a game device or the like.

  The present invention is not limited to the above embodiment as it is, and at the implementation stage, the constituent elements can be modified and embodied without departing from the scope of the invention. In addition, various inventions can be formed by appropriate combinations of a plurality of constituent elements disclosed in the above embodiment. For example, some components of all the components shown in the embodiment may be deleted. Furthermore, components in different embodiments may be combined as appropriate.
