  The digital camera 1 has a CCD 27 as an image sensor. The CCD 27 is disposed on the optical axis of the lens block 21, and the subject is imaged on the light receiving surface of the CCD 27 via the optical system of the lens block 21. The CCD 27 is driven by a vertical and horizontal driver 29 based on a timing signal generated by the timing generator 28 in accordance with a command from the CPU 23, and outputs an analog imaging signal corresponding to the optical image of the subject to the signal processing circuit 30. The signal processing circuit 30 includes a CDS circuit that removes noise included in the output signal of the CCD 27 by correlated double sampling, an A / D converter that converts an imaging signal from which noise has been removed into a digital signal, and the like.

Perform digital signal processing to improve quality. The YUV data converted by the image processing unit 31 is sequentially stored in the SDRAM 32, and is converted into a video signal every time one frame of data (image data) is accumulated in the recording mode. It is sent to the monitor 5 and displayed on the screen as a through image.

  In the still image shooting mode, with the operation of the shutter key 4 as a trigger, the image data obtained by the image processing unit 31 and temporarily stored in the SDRAM 32 is compressed by the CPU 23 and finally a still image of a predetermined format. It is recorded in the external memory 34 as a file.

  The digital camera 1 can be charged with the power key 3, shutter key 4, mode selector switch 6, zoom up button 7 and zoom down button 8, key input unit 36 including the cross key 9, and nickel metal hydride battery. A battery 37, a power control circuit 38 for supplying the power of the battery 37 to the respective units, and a microcomputer 40 for controlling them. The microcomputer 40 regularly scans for operation of various switches and the like in the key input unit 36.

  The digital camera 1 also has a recording function for recording surrounding sounds in the moving image shooting mode, and the CPU 23 has a speaker (SP) 42, a microphone (MIC) 43, and the like via an audio processing block 41. Is connected. The audio processing block 41 processes the audio signal input from the microphone 43 and inputs it to the CPU 23.

  FIG. 3 shows a part of the processing (control) contents assigned to each operation button specified in the photographing control program used in the recording mode among the programs stored in the flash memory 35 described above. FIG. In the figure, “buttons 1 to 6” represent the operation buttons of the zoom up button 7, the zoom down button 8, the up button 10, the down button 11, the left button 12, and the right button 13 shown in FIG. The shooting control program defines, for example, that when the button 1 (zoom up button 7) is operated (pressed) once, the zoom position (zoom magnification) should be moved one step to the telephoto side.

  On the other hand, FIG. 4 is a diagram showing an association table 100 composed of data stored in the flash memory 35. The association table 100 indicates the operation content 100b of the camera body 2 corresponding to the operation buttons (buttons 1 to 6) 100a described above and the ratio 100c of the operation amount (operation frequency) of the operation button with respect to the reference operation amount. Control content information. Here, the operation content 100b is a movement or rotation in a predetermined direction that can be detected by the left / right rotation sensor 44, the vertical movement sensor 45, and the forward / backward movement sensor 46, and the movement amount is a movement amount or a rotation amount (for example, 5 mm). Or 3 mm).

  Next, an operation according to the present invention in the digital camera 1 having the above configuration will be described. FIG. 5 shows the contents of timer interrupt processing executed by the CPU 23 while displaying a through image in, for example, the still image shooting mode in a state where the motion interlocking function provided in the digital camera 1 is set to ON. It is a flowchart.

  After waiting for a timer interruption (step SA1), the CPU 23 immediately acquires the detection values of various sensors such as the left / right rotation sensor 44, the vertical movement sensor 45, and the forward / backward movement sensor 46 (step SA2). At this time, if the camera body 2 is in a stopped state and no detection value is obtained for any sensor (NO in step SA3), the process returns to step SA1 to wait for the next timer interrupt. On the other hand, when the camera body 2 is moving and the detection value is obtained for any sensor (YES in step SA3), the operation content of the camera body 2 is specified based on the acquired detection value and the operation amount is calculated. (Step SA4). It should be noted that the motion amount can be calculated by using the detected value as it is when a sensor capable of directly detecting the movement amount (rotation amount) is used, but the movement (rotation) acceleration as in the present embodiment. In the case where the sensor 44 for detecting the sensor 44 and the sensors 45 and 46 for detecting the movement (rotation) speed are used, the detection value is acquired in step SA2 for a predetermined time, and the integration of the time and the detection value is performed.

Subsequently, after specifying the processing content for the specified operation content based on the association table 100 described above (step SA5), it is determined whether or not the operation amount calculated in step SA4 is equal to or greater than the prescribed reference operation amount described above. (Step SA6). If the reference operation amount has not been reached (NO in step SA7), the process returns to step SA1 and waits for the next timer interrupt. Further, when it is equal to or greater than the reference motion amount (YES in step SA7), the processing specified in step SA5 based on the ratio 100c of the operation amount (number of operations) of the operation button to the reference motion amount shown in the association table 100. A processing amount corresponding to the operation amount of the camera body 2 is calculated for the content (step SA8). That is, assuming that the reference motion amount is a, the ratio (100c) is b, and the actual motion amount is n, the absolute value of X obtained by the following equation is the actual processing amount.
X = a / b × n

  Thereafter, the processing for the calculated actual processing amount is performed (step SA9). For example, if the ratio (100c) is as shown in FIG. 4, the operation content of the specified camera body 2 is “moving forward” and the actual operation amount (n) is 10 mm. Since the processing amount is 2, a process of moving the zoom position to the telephoto side in two steps is executed. Then, after the operation amount of the camera body 2 detected this time is reset at that time (step SA10), the process returns to step SA1 to wait for the next timer interrupt. Thereafter, the above-described processing is repeated. When the photographer gives a still image shooting instruction (pressing the shutter key 4) while the above processing is repeated, the shooting conditions that are sequentially changed by the timer interrupt processing described above are fixed. Take a still image.

  As a result, in the digital camera 1 of the present embodiment, the photographer can change (set) the zoom position, the shutter speed, and the aperture value without operating the various switches shown in FIG. it can. Accordingly, when the camera body 2 is downsized or the liquid crystal monitor 5 is enlarged, the size, arrangement, and number of the various switches described above are sacrificed, and even if the operability of the camera is reduced, the user can take a picture. Workability at the time can be ensured.

  FIG. 6 is a flowchart showing the contents of the associating process executed by the CPU 23 when the setting mode of the motion interlocking function provided in the digital camera 1 is selected by the user.

  In such processing, for example, the CPU 23 displays a predetermined setting screen on the screen of the liquid crystal monitor 5, and first selects one of the above-described operation buttons used at the time of shooting from among the plurality of operation buttons to be associated. An operation button is selected (step SB1). Next, the operation content of the camera body 2 for the selected operation button is selected (step SB2), and the ratio of the operation amount (number of operations) of the operation button to the reference operation amount of the selected operation content is selected (step SB2). SB3). Here, the reference operation amount is a fixed value, and the user is allowed to select only the operation amount (number of operations) of the operation button.

  Then, the association table 100 is updated by storing the contents selected in the above steps in the flash memory 35 in correspondence with each other (step SB4). Thereafter, if another association is designated (YES in step SB5), the process returns to step SB1 and the above-described series of processing is repeated. If no other association is designated (NO in step SB5), the processing is terminated at that point. .

  Thereby, in the digital camera 1, by performing a predetermined operation in the setting mode of the motion interlocking function, the user can change the contents of the association table 100, that is, the relationship between the operation contents of the camera body 2 and the processing contents at the time of shooting, The processing amount corresponding to the operation amount of the camera body 2 can also be set according to preference. That is, of the instruction operations normally performed by pressing the operation key, any instruction operation desired by the user can be replaced with an operation for moving the camera body 2, and the designated instruction operation can be easily performed without a key operation. In addition, key operations for performing other instruction operations can be simplified.

  In the example of the motion interlocking function described above in the present embodiment, the zoom position (zoom magnification) is automatically changed to the telephoto side or the wide angle side according to the movement of the camera body 2 in the front-rear direction, and the change is made. The amount is set to a level corresponding to the amount of movement of the camera body 2. Alternatively, the following operation may be performed according to the movement of the camera body 2 in the front-rear direction. For example, a threshold value is set for the detection signal of the longitudinal motion sensor 46, and when a detection signal indicating forward (or backward) movement exceeding the threshold value is output from the longitudinal motion sensor 46, the zoom position on the telephoto side at that time If the detection signal indicating the movement in the reverse direction exceeding the threshold value is output from the back-and-forth motion sensor 46 after that, the movement of the zoom position is stopped at that time. Also good.

  On the other hand, in the present embodiment, when a photographer instructs to shoot a still image, the shooting conditions that are sequentially changed by the timer interrupt process described above are fixed, and still image shooting is performed. The following may be used.

  For example, when the shutter key 4 is pressed halfway, the shooting conditions that are sequentially changed by the timer interruption process described above may be fixed, and still image shooting may be performed by fully pressing the shutter key 4. By doing so, it is possible to finely adjust the subject angle and the like without unnecessarily changing the shooting conditions while the shutter key 4 is half-pressed. In addition, the timer interruption process described above may be executed only when the shutter key 4 is half-pressed. In this way, an extra operation due to an operation for changing the photographing condition is performed at an unnecessary timing. Power consumption can be reduced.

In the moving image shooting mode, the shooting conditions may be sequentially changed by the timer interrupt process described above from the start to the end of shooting. In addition, the timing for permitting execution of timer interrupt processing or change of shooting conditions by timer interrupt processing is optimal for each shooting condition so as to be optimal according to the nature of the shooting conditions to be changed and the operation content of the main body corresponding to it. You may enable it to set freely for every operation content.
(Embodiment 2)
Next, a second embodiment will be described. This embodiment relates to a digital camera provided with a motion interlocking function different from that of the first embodiment, and FIG. 7 is a perspective view showing the appearance of the digital camera 51 in this embodiment. FIG. 8 is a block diagram showing an outline of the electrical configuration mainly of the digital camera 51.

  Hereinafter, a description will be given of parts different from the digital camera 1 described above. In the digital camera 51, a distance measuring unit 52 is provided on the back surface of the camera body 2 as shown in FIG. 7, and as shown in FIG. A distance measuring sensor 53 disposed inside the distance measuring unit 14 is connected to the microcomputer 40. The distance measuring sensor 53 is a distance measuring sensor for detecting the distance L (see FIG. 11) between the camera body 2 and the photographer M by an arbitrary method, and the detection signal (ranging signal) is stored in the microcomputer 40. It is digitized by the A / D converter provided and sent to the CPU 23. In the present embodiment, the distance measuring sensor 53 is the detection means of the present invention. Since the other parts are the same as those of the digital camera 1 described above, the description thereof is omitted by giving the same reference numerals.

  In the present embodiment, a program for causing the CPU 23 to execute timer interrupt processing different from that of the first embodiment when the motion interlocking function is set on in the recording mode in the flash memory 35. Is remembered.

  FIG. 9 is a flowchart showing the contents of the timer interrupt process. In the following, the CPU 23 waits for a timer interrupt (step SC1), and immediately acquires the distance L between the camera body 2 and the photographer M based on the output signal of the distance measuring sensor 53 described above, and the internal memory or the like. (Step SC2). Subsequently, it is determined whether or not the newly acquired distance L has changed by a certain distance (for example, 3 cm) or more from the previously acquired distance. If there is no change (NO in step SC3), the process returns to step SC1. When there is a change of a certain distance or more (YES in step SC3), the target zoom position is calculated based on the distance value L acquired in step SC2 (step SC4).

  FIG. 10 is a diagram showing the relationship between the target zoom position calculated here and the output of the distance measuring sensor 53 (distance to the photographer). In this embodiment, the distance to the photographer M is shown. When L is within a predetermined tracking distance range C determined in advance, the zoom position of the target zoom position is on the telephoto side in proportion to the distance L as shown in FIG. Note that the range of the calculated target zoom position is the entire controllable zoom range.

  After the target zoom position is calculated, after the process of moving the zoom position at that time to the target zoom position, that is, the optical system driving process in the lens block 21 (step SC5), the process returns to step SC1. Wait for timer interrupt. Thereafter, the above-described processing is repeated.

  Thus, in the digital camera 51 of the present embodiment, the photographer can change the zoom position without operating the zoom-up button 7 and the zoom-down button 8 for changing the zoom magnification shown in FIG. Can do. Therefore, when the camera body 2 is downsized or the LCD monitor 5 is enlarged, the size and arrangement of the zoom-up button 7 and zoom-down button 8 are sacrificed and the operability of the camera body 2 is reduced. The workability at the time of shooting can be ensured.

  In addition, during moving image shooting, when the zoom operation is performed using the zoom up button 7 or the zoom down button 8, camera shake (shake of the screen) is expected to occur with the operation. In the embodiment, since the photographer only needs to move the camera body 2 back and forth, it is possible to prevent the occurrence of the above-mentioned camera shake (screen shake).

  In the first and second embodiments described above, the case where the present invention is applied to a general digital camera has been described. However, the present invention is not limited to this, but other devices such as a mobile phone, for example. It can also be applied to other digital cameras built in the camera.
