[0060] The still image shooting modes include an auto shooting mode, an auto scene determination mode, a manual mode, an aperture priority mode (Av mode), a shutter speed priority mode (Tv mode), and a program AE mode (P mode).

[0061] There are also various scene modes, custom modes, etc., which are shooting settings for different shooting scenes. Using the mode change switch 60, the user can directly switch to one of these modes.

[0062] Alternatively, after switching to a list screen of shooting modes using the mode changeover switch 60, one of the displayed modes may be selected and then switched using other operating members. Similarly, the video shooting mode may include multiple modes.

[0063] A first shutter switch 62 is turned on when the shutter button 61 provided on the digital camera 100 is pressed halfway (instruction to prepare for shooting) and generates a first shutter switch signal SW1.

[0064] The first shutter switch signal SW1 starts photographing preparation operations such as AF (autofocus) processing, AE (auto exposure) processing, AWB (auto white balance) processing, and EF (pre-flash) processing.

[0065] The second shutter switch 64 is turned on when the operation of the shutter button 61 is completed, that is, when the shutter button 61 is fully pressed (a photographing instruction is issued), and generates a second shutter switch signal SW2.

[0066] In response to the second shutter switch signal SW2, the system control unit 50 starts a series of image capture processing operations from reading out a signal from the imaging unit 22 to writing a captured image to the recording medium 200 as an image file.

[0076] The communication unit 54 is capable of transmitting images (including LV images) captured by the imaging unit 22 and images recorded on the recording medium 200, and is also capable of receiving images and various other information from external devices.

[0077] The orientation detection unit 55 detects the orientation of the digital camera 100 with respect to the direction of gravity.

[0078] Based on the attitude detected by the attitude detection unit 55, it is possible to determine whether the image captured by the imaging unit 22 was captured with the digital camera 100 held horizontally or vertically.

[0079] The system control unit 50 can add orientation information corresponding to the attitude detected by the attitude detection unit 55 to the image file of the image captured by the imaging unit 22, or rotate and record the image.

[0080] The attitude detection unit 55 may be an acceleration sensor, a gyro sensor, or the like.

[0081] It is also possible to detect the movement of the digital camera 100 (panning, tilting, lifting, whether it is still or not, etc.) by using an acceleration sensor or a gyro sensor, which is the attitude detection unit 55.

[0082] The eyepiece detection unit 57 is an eyepiece detection sensor that detects the approach (eyepiece approach) and departure (eye separation) of the eye (object) 161 to the eyepiece unit 16 of the finder (approach detection).

[0083] The system control unit 50 switches the display unit 28 and the EVF 29 between display (display state) / non-display (non-display state) depending on the state detected by the eyepiece detection unit 57. EXAMPLES

[0084] Hereinafter, with reference to FIGS. 3, 4 and 5, a description will be given of an exchange module 300 that can be attached to the digital camera 100 in a first embodiment of the present invention.

[0085] (First embodiment) (Exchange module 300) Fig. 3(a) is a front perspective view of a replacement module 300 according to an embodiment of the present invention, and Fig. 3(b) is a rear perspective view.

[0092] (Shape of replacement module fixing part) 6 and 7, a description will be given of a digital camera 100 in a first embodiment of the present invention in which the cross key 74 of the digital camera 100 is replaceable with a rotatable operation member 301. FIG.

[0093] Fig. 6 is an enlarged perspective view of the replacement module fixing portion when the digital camera 100 according to the embodiment of the present invention is viewed from the back. Fig. 7 is an exploded perspective view of the periphery of the replacement module fixing portion when the digital camera 100 is viewed from the front.

[0094] The shape of the replacement module fixing portion of the digital camera 100 will be described in detail with reference to FIGS.

[0095] The fixing ring 403 is provided rotatably on the rear housing 400 of the digital camera 100 .

[0096] The lock release lever 403a is a part of the fixing ring 403, and is exposed to the outside through an opening in the rear housing 400 so that the user can operate it.

[0097] The fixing ring 403 is biased in the rotational direction by a slider biasing spring 405 via a slider 406 .

[0098] Movable pin 403 b is a part of fixed ring 403 , and is exposed to the outside through an opening formed by rear housing 400 and fixed portion housing 404 .

[0099] In this embodiment, two movable pins 403b are provided, but there is no limit to the number. The fixed pin 400a is formed by a part of the rear housing 400 protruding.

[0100] In this embodiment, three immobile pins 400a are provided, but there is no limit to the number.

[0101] The fixed pin 400a and the movable pin 403b engage with the fixed pin groove 302a and the movable pin groove 302b of the replacement module 300, respectively, so that the replacement module 300 can be fixed.

[0102] The detailed shapes of the stationary pin 400a, the movable pin 403b, the stationary pin groove 302a and the movable pin groove 302b will be described later.

[0103] A communication terminal 401 provided in an opening of the fixed housing 404 is connected to a communication board 407 .

[0104] When the replacement module 300 is fixed to the digital camera 100, the replacement module 300 communicates with the system control unit 50 via the communication board 407, making it possible to perform various operations on the digital camera 100.

[0105] The drip-proof member 402 is fixed to the fixed housing 404 so as to surround the communication terminal 401 .

[0106] When the replacement module 300 is fixed to the digital camera 100, the drip-proof member 402 comes into contact with the rear housing of the replacement module 300, making it possible to prevent liquid from entering the communication section.

[0107] (Module fixing part operation) The operation of the module fixing portion of digital camera 100 by operating lock release lever 403a in the first embodiment of the present invention will be described below with reference to FIGS.

[0108] Here, a state in which the unlocking lever 403a is not operated will be referred to as a locked state, and a state in which the unlocking lever 403a is operated will be referred to as an unlocked state.

[0109] FIG. 8(a) is an enlarged view of the replacement module fixing portion in the unlocked state when the digital camera 100 according to the embodiment of the present invention is viewed from the rear.

[0110] FIG. 8(b) is an enlarged view of the replacement module fixing portion in the locked state when the digital camera 100 is viewed from the rear.

[0112] FIG. 9B is an enlarged view of the internal structure of the digital camera 100 in the locked state around the replacement module fixing portion when viewed from the front.

[0113] The module fixing operation of the digital camera 100 by operating the lock release lever 403a will be described with reference to FIGS.

[0114] The fixing ring 403 is biased in a rotational direction (clockwise direction in FIG. 8) by a slider biasing spring 405 via a slider 406 .

[0115] By operating the unlock lever 403a from the locked state, the fixing ring 403 rotates in the opposite direction to the biasing direction of the slider biasing spring 405 (counterclockwise direction in FIG. 8), and the state transitions to the unlocked state.

[0116] This action changes the relative phase between the stationary pin 400a and the movable pin 403b.

[0117] When the operation of the lock release lever 403a is stopped from this state, the fixing ring 403 rotates in the biasing direction of the slider biasing spring 405, and the state transitions again to the locked state.

[0118] If consideration is given to preventing rattling during fixing, it is preferable to arrange two or more movable pins 403b at equal intervals along the outer periphery of the side surface of the replacement module 300 as shown in this embodiment.

[0119] Furthermore, if consideration is given to uniquely determining the mounting phase of the replacement module 300, it is preferable that in the unlocked state as shown in this embodiment, the fixed pin 400a and the movable pin 403b are arranged at unequal intervals along the outer periphery of the side of the replacement module 300.

[0120] (Fixing operation of replacement module 300) The fixing operation of the replacement module 300 in the first embodiment of the present invention will be described below with reference to FIGS.

[0121] FIG. 10(a) is a schematic diagram showing an engagement state between the replacement module 300 according to the first embodiment of the present invention and the immobile pin 400a and the movable pin 403b in an unlocked state.

[0122] FIG. 10(b) is a schematic diagram showing an engagement state of the replacement module 300, the immobile pin 400a, and the movable pin 403b according to the first embodiment of the present invention in a locked state.

[0123] FIG. 11A is a cross-sectional view of the internal structure of the digital camera 100 and replacement module 300 according to the embodiment of the present invention in an unlocked state.

[0124] FIG. 11B is a cross-sectional view of the internal structure of the digital camera 100 and the exchange module 300 according to the embodiment of the present invention in a locked state.

[0125] The fixing operation of the replacement module 300 will be described with reference to FIGS.

[0126] In the first embodiment of the present invention, the stationary pin groove 302 a is provided parallel to the direction in which the replaceable module 300 is inserted into the digital camera 100 .

[0127] On the other hand, the movable pin groove portion 302 b has a shape that is bent from the direction in which the replacement module 300 is inserted into the digital camera 100 towards the rotational biasing direction of the slider biasing spring 405 .

[0128] When the replacement module 300 is inserted into the digital camera 100 in the unlocked state, the movable pin 403b is located at the bending point of the movable pin groove portion 302b.

[0129] When the state transitions from this state to the locked state, the movable pin 403b moves to the locked position along the curved shape of the movable pin groove 302b.

[0130] At this time, the replacement module 300 moves a distance L between the bending point and the lock position in the insertion direction parallel to the direction in which the replacement module 300 is inserted into the digital camera 100. By performing such a module attachment / detachment operation, it is possible to prevent wear on the electrical contacts 304a and the communication terminal 401 during attachment and detachment.

[0131] When the replacement module 300 transitions from a locked state to an unlocked state, it pops up from the rear housing 400 of the digital camera 100 by a distance L according to the shapes of the immovable pin groove portion 302a and the movable pin groove portion 302b.

[0132] This makes it possible to grip the side of the operation member 301 when removing the replacement module 300 from the digital camera 100.

[0133] Furthermore, in the unlocked state, the electrical contact 304a and the communication terminal 401 are in a position where they do not come into contact with each other, so that malfunctions when the replacement module 300 is attached or detached can be prevented.

[0134] In this embodiment, the immobile pin 400a is provided on the digital camera 100, and the immobile pin groove portion 302a is provided on the replacement module 300, but the relationship of the pin and the groove may be reversed.

[0135] In addition, in this embodiment, since the replacement module 300 is cylindrical, the lock release lever 403a rotates, but the replacement module 300 may be in another shape, such as a rectangular parallelepiped shape.

[0136] In that case, the lock release lever 403a may have a linear sliding configuration.

[0137] (Second Example) The fixing operation of the replacement module 300 in the second embodiment of the present invention will be described below with reference to FIG.

[0138] FIG. 12(a) is a schematic diagram showing an engagement state of the replacement module 300 according to the second embodiment of the present invention with a stationary pin 400a and a movable pin 403b in an unlocked state.

[0139] FIG. 12(b) is a schematic diagram showing an engagement state of the replacement module 300 according to the second embodiment of the present invention with the immobile pin 400a and the movable pin 403b in a locked state.

[0140] The fixing operation of the exchange module 300 in the second embodiment of the present invention will be described with reference to FIG.

[0141] Here, the digital camera 100 and the exchange module 300 in the second embodiment of the present invention are basically the same as those in the first embodiment.

[0142] Therefore, in the following, the differences between the two will be mainly described, and the description of the similarities will be omitted. Also, the same reference numerals will be used to denote the same parts as in the first embodiment.

[0143] In the second embodiment of the present invention, the immovable pin groove portion 302 a has a shape that is bent in a direction opposite to the rotational bias of the slider bias spring 405 from the direction in which the replacement module 300 is inserted into the digital camera 100 .

[0144] On the other hand, the movable pin groove portion 302 b is provided parallel to the direction in which the replacement module 300 is inserted into the digital camera 100 .

[0145] When the replacement module 300 is inserted into the digital camera 100 in the unlocked state, the immobile pin 400a is located at the bending point of the immobile pin groove portion 302a.

[0146] When the state transitions from this state to the locked state, the movable pin 403b moves to the locked position while rotating the replacement module 300.

[0147] At this time, the replacement module 300 rotates and at the same time moves parallel to the direction in which the replacement module 300 is inserted into the digital camera 100 by a distance L in the insertion direction between the bending point and the lock position.

[0148] Such a module attachment / detachment operation has the effect of removing dirt adhering to the surfaces of the electrical contacts 304a and the communication terminals 401, making it possible to reduce poor electrical continuity. (Third Example) Hereinafter, with reference to FIG. 13, a fixing operation of the replacement module 300 in the third embodiment of the present invention will be described.

[0149] FIG. 13(a) is a schematic diagram showing an engagement state of the replacement module 300, the immobile pin 400a and the movable pin 403b according to the third embodiment of the present invention in an unlocked state.

[0150] FIG. 13(b) is a schematic diagram showing an engagement state of the replacement module 300 according to the third embodiment of the present invention with the immobile pin 400a and the movable pin 403b in a locked state.

[0151] The fixing operation of the exchange module 300 in the third embodiment of the present invention will be described with reference to FIG.

[0152] Here, the digital camera 100 and the exchange module 300 in the third embodiment of the present invention are basically the same as those in the first embodiment.

[0156] On the other hand, the movable pin groove portion 302 b is bent from the direction in which the replacement module 300 is inserted into the digital camera 100 to the rotational biasing direction of the slider biasing spring 405 .

[0157] Then, the replacement module 300 is provided parallel to the direction in which the replacement module 300 is inserted into the digital camera 100 .

[0158] When the replacement module 300 is inserted into the digital camera 100 in the unlocked state, the immobile pin 400a is located at the bending point of the immobile pin groove portion 302b.

[0159] When transitioning from this state to the locked state, the movable pin 403b moves parallel to the direction in which the replacement module 300 is inserted into the digital camera 100, and then moves to the locked position while rotating the replacement module 300.

[0160] In this way, it is possible to switch between linear motion and rotation when attaching and detaching by devising the shapes of the fixed pin groove portion 302a and the movable pin groove portion 302b of the replacement module 300. This makes it possible to adjust the attachment and detachment behavior in accordance with the shapes of the electrical contact 304a and the communication terminal 401.
