That is, the image sensor 90 is properly exposed, and an image signal corresponding to the subject image is output from the image sensor 90.

The shutter mechanism section 89 performs light shielding control for the image sensor 90 by running a shutter curtain. The shutter mechanism section 89 includes a light shielding member (mechanical rear curtain), and completes the exposure of the image sensor 90 by the shutter mechanism section 89. In the image sensor 90, electronic front curtain processing is performed before the shutter mechanism section 89 runs the rear curtain. This is a process that controls the timing of exposure start by resetting charges for each line. In the electronic front curtain mode, exposure control is performed by synchronizing the charge reset operation of the image sensor 90 and the movement of the rear curtain of the shutter mechanism section 89. Since the electronic front curtain technology is well known, a detailed explanation thereof will be omitted.

The image processing unit 83 includes an A/D converter, a white balance adjustment circuit, a gamma correction circuit, an interpolation calculation circuit, and the like. For example, the image processing unit 83 performs color interpolation (demosaicing) processing on the Bayer array signal acquired from the image sensor 90 to generate color image data, and outputs the image data for recording to the storage unit 84.

Further, the image processing section 83 performs data compression of still images and moving images, and the audio control section 82 compresses audio data to be recorded. The audio data compressed by the audio control unit 82 is synthesized into a moving image or a still image by an image processing unit 83, and then output to the storage unit 84. The storage unit 84 includes a nonvolatile memory and stores various data including image data. The camera system control unit 81 performs a process of storing data in the storage unit 84 and a process of outputting data read from the storage unit 84 to the display unit 85 and presenting it to the user. Note that the display section 85 in FIG. 2 corresponds to the display section 2 and the outside viewfinder display section 4 in FIG. 1.

The camera system control unit 81 controls imaging processing, image processing, recording and reproducing processing, etc. in accordance with user operation signals. The operation detection unit 86 detects, for example, depression of a shutter release button. The first switch is turned on by pressing the shutter release button halfway. Furthermore, when the user fully presses the shutter release button, the second switch is turned on. When the camera system control unit 81 receives a shooting instruction by operating the second switch from the operation detection unit 86, it performs drive control of the image sensor 90, image processing, compression processing, etc., and also displays image information on the screen of the display unit 2. control to display etc. Further, the operation detection section 86 detects, for example, an operation on the touch panel 3 (FIG. 1(b)) provided on the back surface of the camera, and transmits the user's operation instruction to the camera system control section 81.

Furthermore, the camera system control unit 81 calculates an appropriate focal position and aperture value based on the signal from the image sensor 90. That is, the camera system control unit 81 detects photometry and focus state based on the output signal of the image sensor 90, and determines, for example, the F value, shutter speed, etc. as exposure conditions. The camera system control unit 81 controls the exposure of the image sensor 90 through aperture control and shutter control. The camera system control section 81 transmits a command signal to the lens system control section 72 via the communication terminal 20. The lens system control section 72 controls the lens drive section 73 according to a command signal from the camera system control section 81 .

The camera system control section 81 controls the operation of each section of the imaging device 1 according to user operations, thereby capturing still images and moving images. That is, when a user instructs to shoot a still image or a moving image using the operation member of the imaging device 1, the camera system control section 81 controls the shooting operation according to the operation signal from the operation detection section 86. The camera system control section 81 calculates a target value based on the detection signal from the blur detection section 87, and drives the blur correction section 88. That is, the camera system control section 81 is responsible for generating the target value based on the detection signal of the blur detection section 87 and driving control of the blur correction section 88. At this time, the camera system control unit 81 controls the image blur correction operation according to shooting conditions, exposure conditions, and the like.

To briefly explain the flow of drive control of the blur correction section 88, the user performs the S1 operation, the operation detection section 86 detects this, and the photographing preparation operation is started. In order to facilitate the user's composition determination during a so-called aiming operation for determining a composition, the image blur correction unit 88 performs image blur correction. That is, the image sensor 90 is driven (moved or rotated) under the control of the shake correction section 88 based on the detection signal of the shake detection section 87. Thereafter, the user performs a second switch operation, and the operation detection section 86 detects this, and a photographing operation (image recording operation) is started. At this time, in order to suppress image blur of the subject image obtained by the exposure operation, the image sensor 90 is driven by controlling the blur correction section 88 based on the detection signal of the blur detection section 87. When a certain period of time has elapsed after exposure, the image blur correction operation is stopped.

As a result, the microphone 530 is not affected by the magnet 175.

Further, a magnetic force sensor (not shown) such as GMR (Giant Magnet Resistance) is arranged on the side of the imaging device 1 facing the magnet 175, and by detecting the magnetic force of the magnet 175 with the magnetic force sensor, the display unit 2 The position of is detected.

The user raises the frame portion 172 of the display portion 2 near the recessed portion 112 with a finger and rotates the display portion 2 in the direction of arrow B (see FIG. 6(a)) about the rotation axis 160 to rotate the display portion 2. It can be moved to the open position. In the open state of the display section 2 (see FIG. 6(b)), the display surface of the display section 2 faces the subject. The hinge section 170 of the display section 2 is configured to be rotatable in the direction of arrow C (see FIG. 6(b)) about the rotation axis 162, and turns the display surface toward the user when the display section 2 is in the open position. You can also do that.

Since the magnet 175 is arranged at one end of the display unit 2 on the hinge unit 170 side, even if the attitude of the display unit 2 changes, the position detection magnet 175 does not come close to the microphone 530 and the microphone 530 There is no unnecessary influence due to the magnetic force of the magnet 175.

According to the present embodiment, the recess 112 is provided in the rear cover 100 that forms the back surface of the imaging device 1, the microphone 530 that collects sound through the microphone hole 110 on the inner wall surface is provided, and the rear cover 100 is formed in the recess 112. An opening 114 is provided on the bottom surface, which is different from the back surface. As a result, even if the user accidentally blocks the back side of the recess 112, the opening on the bottom side of the recess 112 is opened, thereby preventing the microphone hole from being blocked.

In this embodiment, the recess 112 having the microphone hole 110 is provided on the back side of the imaging device 1, but if the microphone 530 is in a position where it can collect sound, it may be placed on the top side of the imaging device 1, for example. You can. In this case, the recess 112 has an opening that opens to the back or front of the imaging device 1.
