  FIG. 5 is a block diagram showing a system configuration of the electronic camera 2 according to the embodiment. As shown in FIG. 5, the electronic camera 2 is configured by a microprocessor or the like, and includes a control unit 50 that comprehensively controls each unit of the electronic camera 2. The control unit 50 includes a release button 8, a shooting mode dial 10, a built-in flash 12, an image sensor 18, an ASIC 24, a multi selector 30, a finder 32, a liquid crystal panel 34, a recording medium 52, an arm drive unit 54, and a temperature detection unit 56. Is connected.

  The control unit 50 executes shooting preparation and shooting for shooting still images and moving images in accordance with the shooting mode set by the shooting mode dial 10 and the operation of the release button 8. The imaging element 18 is configured by a CCD, a CMOS, or the like, images the light from the subject via the photographing lens 6a, and outputs an imaging signal to the control unit 50. The ASIC 24 performs various types of image processing on the imaging signal from the imaging element 28 to generate image data. The recording medium 52 is a portable recording medium that is detachably mounted in a card slot (not shown) provided in the electronic camera 2, and for example, a CF card, an SD card, smart media, or the like is used. On the recording medium 52, image data generated by the ASIC 24 is recorded. The arm drive unit 54 drives the movable unit 16 (arms 16a and 16b) in accordance with a control signal from the control unit 50. The temperature detection unit 56 is disposed in the vicinity of the image sensor 18, detects the temperature of at least one of the image sensor 18 and the vicinity thereof, and outputs the detected temperature to the control unit 50.

  In this embodiment, when the control unit 50 shifts to the moving image shooting mode, the control unit 50 determines whether or not to open the movable unit 16 and the panel housing 36 based on the detection result by the temperature detection unit 56, and the determination result. Based on the above, the processing related to the opening and closing of the movable portion 16 and the panel housing 36 is controlled. Specifically, when it is detected by the temperature detection unit 56 that the temperature has risen to the first preset temperature, it is determined that the movable unit 16 should be opened, and the temperature detection unit 56 sets the preset temperature. When it is detected that the temperature has risen to the second temperature higher than the first temperature, it is determined that the panel housing 36 should be opened. Hereinafter, with reference to the flowchart shown in FIG. 6, processing when the electronic camera 2 according to this embodiment is shifted to the moving image shooting mode will be described.

  First, when the shooting mode dial 10 is operated by the user and set to the moving image shooting mode, the control unit 50 acquires the resolution of the moving image when shooting as a moving image, and the first based on the acquisition result. A temperature and a second temperature higher than the first temperature are set (step S10).

For example, when shooting at a high resolution, such as when shooting at a resolution of 1080i, the temperature of the image sensor 18 is expected to rise sharply, as shown by graph A in FIG. Thus, the temperature of the image pickup device 18 is subjected to a heat dissipation early so as not to reach the Tmax, a temperature T ₁ of a lower temperature than if for example are taken in the low resolution first temperature, the temperature T ₄ second Set to temperature. Note that the temperature Tmax is a limit temperature, and when the moving image is being captured and reaches the temperature Tmax, the control unit 50 forcibly ends the moving image capturing.

Further, for example, in the case of shooting at a resolution that is not high resolution, such as when shooting at a resolution of 720p, it is expected that the temperature of the image sensor 18 rises as shown in graph B of FIG. Therefore, in order to take measures against heat dissipation so that the temperature of the image sensor 18 does not reach Tmax, for example, a temperature T ₂ that is lower than when shooting at high resolution and higher than when shooting at low resolution is set. the first temperature, sets the temperature T ₅ in the second temperature.

Further, for example, when photographing at a low resolution, it is expected that the temperature of the image sensor 18 gradually increases as shown in the graph C of FIG. Therefore, in order to perform the heat dissipation so that the temperature of the image sensor 18 does not reach Tmax, the temperature T ₃ is a temperature higher than when, for example, is photographed at high resolution to the first temperature, the temperature T ₆ in the second temperature Set.

  Next, the control unit 50 determines whether or not the temperature detection unit 56 has detected that the temperature has increased to the first temperature (step S11). When it is detected in step S11 that the temperature has risen to the first temperature (step S11, Yes), the control unit 50 determines whether or not the movable unit 16 is housed (step S12). When it is determined in step S12 that the movable portion 16 is stored (step S12, Yes), that is, when the movable portion 16 is not in the state shown in FIG. 1B but in the state shown in FIG. The control part 50 pops up the movable part 16 via the arm drive part 54 (step S13).

  Specifically, the control unit 50 outputs a control signal to the arm driving unit 54, and the arm driving unit 54 rotates the arms 16 a and 16 b of the movable unit 16 in accordance with the control signal from the control unit 50. The state in which the movable part 16 (built-in flash 12) is housed (the closed state, the state shown in FIG. 1A) is raised (the open state, the state shown in FIG. 1B). Move to. By popping up the movable portion 16 in this way, the external surface area of the flash housing 14 can be increased, and as a result, the heat dissipation efficiency can be increased. It should be noted that before popping up the movable part 16 in step S13, a message that pops up the movable part 16 for heat radiation, not for the light emitting operation of the built-in flash 12 (for example, “raise the built-in flash for heat radiation” A message such as “The built-in flash will not emit light” can also be displayed on the liquid crystal panel 34. Further, when popping up the movable part 16, the light emission operation of the built-in flash 12 can be prohibited in order to prevent the temperature of the electronic camera 2 from rising due to the light emission of the built-in flash 12.

  On the other hand, when it is determined in step S12 that the movable portion 16 is stored (No in step S12), that is, the movable portion 16 is not in the state shown in FIG. 1A but in the state shown in FIG. In that case, the control unit 50 proceeds to the process of step S14.

  Next, the controller 50 determines whether or not the temperature detector 56 has detected that the temperature has risen to the second temperature (step S14). When it is detected in step S14 that the temperature has risen to the second temperature (step S14, Yes), the control unit 50 determines whether or not the panel housing 36 is housed (step S15). For example, an optical sensor (not shown) having a light projecting unit and a light receiving unit, a metal and a magnetic sensor (not shown) that reacts with magnetism, protrudes when the panel housing 36 is opened, and is buried when the panel housing 36 is closed. Any switch (not shown) or the like is provided in the electronic camera 2, and it is determined whether or not the panel housing 36 is housed based on the detection result. When it is determined in step S15 that the panel housing 36 is housed (step S15, Yes), that is, the panel housing 36 is not in the state shown in FIG. 3B but in the state shown in FIG. In this case, the control unit 50 displays a message indicating that the panel housing 36 should be opened (for example, a message such as “Please open the liquid crystal panel to dissipate heat”) on the liquid crystal panel 34 (step S16).

  An image for instructing to open the panel housing 36, a temperature rise warning mark, or the like can be displayed together with or instead of the message. In this way, when the user is prompted to open the panel housing 36 and the user opens the panel housing 36 according to a message or the like, the appearance surface area of the panel housing 36 can be increased. Efficiency can be increased. Simultaneously with the processing in step S16, a mark indicating that the panel housing 36 should be opened can be displayed on the finder 32 in a superimposed manner. Display of a mark or the like on the finder 32 is effective when the user is looking through the finder 32 and is not viewing the liquid crystal panel 34.

  Next, the control unit 50 determines whether or not the mode is changed from the moving image shooting mode to another mode, and the processes of steps S10 to S16 are performed until it is determined that the moving image shooting mode is changed to another mode. repeat.

  According to the electronic camera 2 according to this embodiment, when the first temperature is first reached, the heat radiation efficiency is increased by popping up the movable portion 16 that does not affect the moving image shooting, and the first temperature higher than the first temperature. When the temperature reaches two, the heat dissipation efficiency is increased by opening the panel housing 36 that can greatly increase the external surface area. Therefore, heat generated from electronic components such as the image sensor 18 can be efficiently released to the outside air without increasing the size of the apparatus main body and without increasing costs. Therefore, it is possible to prevent the moving image shooting from being forcibly terminated by reaching the limit temperature during moving image shooting, and to increase the time for moving image shooting.

  In the above-described embodiment, based on the determination result of whether or not the control unit 50 should open the movable unit 16 and the panel housing 36, the process related to opening and closing of the movable unit 16 and the panel housing 36 is performed. Although controlled, the control unit 50 may be configured to reduce the processing load of at least one of the image sensor 18 and the ASIC 24 together with the processing related to opening and closing. For example, by reducing the number of pixels read from the image sensor 18, the frame rate of the image sensor 18 (the number of image signals read from the image sensor 18 per unit time), etc., the processing load on the image sensor 18 and the ASIC 24 is reduced. be able to. In this case, although the image quality such as the resolution of the moving image is deteriorated, it is possible to delay reaching the limit temperature, so that the moving image shooting time can be lengthened.

  In the above-described embodiment, while the moving image shooting mode is set, the temperature of the image sensor 18 and the like is detected and the process related to the opening and closing of the movable part 16 and the like is controlled. The same processing may be executed while displayed on the liquid crystal panel 34. Even when an operation for instructing power-off of the electronic camera 2 (pressing a power switch (not shown)) is performed by the user, the temperature of the image sensor 18 or the like is detected before the power-off is performed, and the movable portion 16 is detected. A process related to opening and closing such as may be executed. Specifically, it is determined whether or not the temperature detected by the temperature detection unit 56 is equal to or higher than a predetermined temperature set in advance. If the temperature is equal to or higher than the predetermined temperature, at least the movable unit 16 and the panel casing 36 are at least. The process for opening one is executed. For example, when the temperature is equal to or higher than a predetermined temperature, a message indicating that the movable portion 16 is opened and the panel housing 36 is opened is displayed on the liquid crystal panel 34 or the like. Further, for example, when the temperature is equal to or higher than the first temperature, the movable portion 16 is opened, and when the temperature is higher than the second temperature, a message or the like indicating that the movable portion 16 is opened and the panel housing 36 is opened is displayed on the liquid crystal panel 34 or the like. In this case, when the power supply camera 2 is turned on next time and a moving image is shot in the moving image shooting mode, a moving image can be taken for a long time. That is, the time until reaching the limit temperature is calculated based on the temperature (initial temperature) of the electronic component at the start of moving image shooting, and the moving image shooting time is set based on the calculation result. Since it can be lowered, the time until the limit temperature is reached is added, and a longer moving image shooting time is set.

  Further, in the above-described embodiment, when the temperature detection unit 56 detects that the temperature has risen to the first temperature, it is determined that the movable unit 16 should be opened, and the temperature detection unit 56 has raised the temperature to the second temperature. , It is determined that the panel housing 36 should be opened. However, when the temperature detection unit 56 detects that the temperature has risen to the first temperature, it is determined that the panel housing 36 should be opened. However, when the temperature detecting unit 56 detects that the temperature has risen to the second temperature, the movable unit 16 may be determined to be opened. Further, it may be configured that when the temperature detection unit 56 detects that the temperature has risen to the first temperature or the second temperature, the movable unit 16 and the panel housing 36 should be opened. In addition, when the third temperature higher than the first temperature and lower than the second temperature is set and the temperature detection unit 56 detects that the temperature has risen to the third temperature, the movable unit 16 and the panel housing 36 should be opened. It may be configured to discriminate.

  In the above-described embodiment, the first temperature and the second temperature are set based on the resolution of the moving image. However, the temperature increase rate of the temperature detected by the temperature detection unit 56 at a predetermined time interval is calculated. And you may make it the structure which sets 1st temperature and 2nd temperature based on a calculation result. That is, when the temperature increase rate is large (for example, as shown in the graph A of FIG. 7), the first temperature and the second temperature are set to low temperatures, and when the temperature increase rate is small (for example, the graph of FIG. 7). In the case shown in C), the first temperature and the second temperature are set to high temperatures.

  In the above-described embodiment, the temperature detection unit 56 is provided in the vicinity of the image sensor 18, but the temperature detection unit is provided not only in the vicinity of the image sensor 18 but also in the vicinity of the ASIC 24 and other electronic components that generate heat. You can also. When a plurality of temperature detection units are provided in this way, if any one of the temperature detection units detects that the temperature has risen to the first temperature or the second temperature, the control unit 50 can move the movable unit 16 or the panel housing. It is determined that the body 36 should be opened. In addition, when the average temperature detected by the plurality of temperature detection units rises to the first temperature or the second temperature, it is possible to determine that the movable unit 16 and the panel housing 36 should be opened. .

  In the above-described embodiment, the temperature detector 56 is provided in the vicinity of the image sensor 18 to detect the temperature of the image sensor 18. However, the temperature detector 56 is provided at a predetermined position, and the image sensor 18 and the ASIC 24 are provided. For example, the temperature of each electronic component that generates heat may be detected. In this case, the relationship between the temperature detected by the temperature detection unit 56 arranged at a predetermined position and the temperature of each electronic component is obtained in advance through experiments or the like, and based on the temperature detected by the temperature detection unit 56, each The temperature of the electronic component is predicted, and processing related to opening and closing of the movable portion 16 and the panel housing 36 is controlled based on the prediction result.

  In the above-described embodiment, a message indicating that the panel housing 36 should be opened is displayed on both the liquid crystal panel 34 and the finder 32, but it is determined whether or not the electronic camera 2 is looking into the finder 32. If the eye sensor is equipped with an eye sensor or the like and it is determined that the eye sensor is looking into the finder 32, the liquid crystal panel 34 is turned off, and a message can be displayed only on the finder 32. . When the eye sensor determines that the finder 32 is not being looked at, a message indicating that the panel housing 36 should be opened is displayed only on the liquid crystal panel 34, or along with the message, “The liquid crystal panel is turned off. The display operation of the liquid crystal panel 34 is stopped after the message such as “Please do” is displayed for several seconds, that is, the liquid crystal panel 34 can be turned off. Thus, by turning off the liquid crystal panel 34, it is possible to prevent the temperature of the electronic camera 2 from rising due to heat generated from the liquid crystal panel 34.
