[0008] Hereinafter, electronic devices according to embodiments of the present invention will be described in detail with reference to the drawings. In the following description, an imaging device will be taken as an example of an electronic device. The imaging device is suitable for installation as a surveillance camera or a monitoring camera in hospitals, nursing homes, factories, stores, and public transportation vehicles such as trains and buses, although there is no particular limitation on its use. The imaging device is detachably attached to an external device provided in the facility or room in which the imaging device is installed. An example of an external device to which the imaging device can be attached is a lighting device such as a fluorescent tube lamp.

[0009] The imaging device can also switch between normal imaging mode and night vision mode depending on the brightness of the surrounding external environment. In normal imaging mode, imaging is performed using light incident on the imaging optical system (optical member) when the external environment is bright. In night vision mode, illumination light is emitted when the external environment is dark, and an image of a subject illuminated by the illumination light is captured.

[0010] <First embodiment> <Overall configuration of the imaging device and external device to which the imaging device is attached> 1 is a perspective view showing the appearance of an imaging device 10 which is an electronic device according to a first embodiment, and an illumination device 80 which is an external device to which the imaging device 10 is detachably attached. The imaging device 10 is connected to a battery 70 which is detachably attached to the illumination device 80.

[0011] <Lighting Device 80> The lighting device 80 is, for example, a straight-tube fluorescent lamp having a cylindrical outer diameter. In the following description, the direction in which the lighting device 80 extends is referred to as the extension direction, and the X-axis is set along the extension direction as shown in FIG.

[0012] The lighting device 80 has a power terminal 81 on each of the outer wall surfaces 82 (see FIG. 2) at both ends in the X-axis direction. Two power terminals 81 are provided on each of the outer wall surfaces 82 on the X-axis + side and the X-axis - side of the lighting device 80. In the following description, the direction in which the two power terminals 81 provided on each end of the lighting device 80 in the X-axis direction are arranged is referred to as the arrangement direction. The arrangement direction is a direction intersecting (perpendicular or substantially perpendicular) the extension direction, and the Y-axis is set along the arrangement direction as shown in FIG. 1. The power terminal 81 is columnar and protrudes from the outer wall surface 82 and extends along the X-axis direction (i.e., the extension direction), and is inserted into a socket provided on a member to which the lighting device 80 is attached, and connected to a commercial power supply unit.

[0013] <Imaging device 10> Fig. 2 is an exploded perspective view of the imaging device 10. As shown in Fig. 1 and Fig. 2, the imaging device 10 includes a camera module 11, a housing (exterior case) 12 which is a main body, an illumination unit 16, a connection terminal 20, a connector 25, a memory slot 26, a control unit 31, an attachment unit 40, a board 50, and a cover unit 60. As will be described in detail later, the camera module 11 is accommodated in the housing 12, and includes an imaging element 110 and a lens (optical member) 111.

[0014] <Housing 12> 1, the housing 12 is composed of a front case 120 and a rear case 121. The front case 120 includes a rectangular or substantially rectangular ceiling plate 122 and side wall plates 123a, 123b, 123c, and 123d that are connected to each side of the ceiling plate 122. The ceiling plate 122 and the side wall plates 123a, 123b, 123c, and 123d are integrally molded from synthetic resin, with the side wall plate 123a connected to one long side of the ceiling plate 122 and the side wall plate 123b connected to the other long side of the ceiling plate 122. The side wall plate 123c is connected to one short side of the ceiling plate 122, and the side wall plate 123d is connected to the other short side of the ceiling plate 122.

[0015] In the following description, the direction perpendicular to the X-axis and Y-axis and extending from the rear case 121 of the housing 12 to the front case 120 is referred to as the Z-axis. The direction along the Z-axis may be referred to as the intersecting direction intersecting with the extension direction along the X-axis. The intersecting direction is also the direction along the optical axis L of the lens 111 of the camera module 11 described later.

[0016] 1 and 2, the ceiling plate 122 of the housing 12 is an exterior plate that intersects with the optical axis L of the lens 111 of the camera module 11. An opening 125 and four illumination openings 126 are formed in the ceiling plate 122. The opening 125 is formed in a circular or approximately circular shape centered on a position where the optical axis L of the lens 111 passes through. The lens 111, which will be described later, is inserted into this opening 125. In this embodiment, the description will be given assuming that the optical axis L of the lens 111 passes through the center of the ceiling plate 122.

[0017] Incidentally, the optical axis L of the lens 111 is not limited to passing through the center of the ceiling board 122. The optical axis L of the lens 111 may pass through a position shifted from the center of the ceiling board 122 to the + or - side of the X axis, or may pass through a position shifted from the center of the ceiling board 122 to the + or - side of the Y axis.

[0018] The illumination openings 126 are formed at the four corners of the ceiling plate 122. The illumination openings 126 are formed to allow illumination light emitted from an illumination unit 16 (described later) disposed inside the housing 12 to pass to the outside of the imaging device 10.

[0019] The rear case 121 is fixed to the front case 120 and closes the bottom (lower side) of the front case 120. The rear case 121 is fixed to the front case 120 by, for example, screw connection. The rear case 121 has a bottom surface 121a that faces the ceiling plate 122 of the front case 120 when fixed to the front case 120. Furthermore, screw holes are formed in the bottom surface 121a, and the rear case 121 is fixed to the mounting portion 40 (described later) by screw connection with screws inserted into the screw holes. That is, the housing 12, which is the main body, is fixed to the mounting portion 40.

[0020] An opening 121b for a board is formed in a side surface on the positive side of the X-axis of the rear case 121. A board 50, which will be described later, is inserted into the opening 121b for a board. A connector opening 121c is formed in a side surface on the negative side of the X-axis of the rear case 121. Note that the opening 121b for a board and the connector opening 121c are not limited to being formed on the side surface of the rear case 121, and may be formed on the bottom surface 121a of the rear case 121 or on the front case 120.

[0021] <Camera Module 11> 2, the camera module 11 includes an imaging element (image sensor) 110 such as a CMOS or a CCD, a lens 111, and a filter unit 118. The imaging element 110 is mounted on a substrate 112 and housed in the housing 12. The lens 111 is disposed on the Z axis + side of the imaging element 110 and held by a lens holder 113. The lens 111 held by the lens holder 113 is disposed at a position protruding on the Z axis + side with respect to the ceiling plate 122 through an opening 125 formed in the ceiling plate 122 of the housing 12 described above. The substrate 112 on which the imaging element 110 is mounted is fixed to the Z axis - side of the lens holder 113 by, for example, screw connection.

[0022] Subject light arriving from outside the imaging device 10 is guided by the lens 111 to the light receiving surface of the imaging element 110 and collected. In other words, the lens 111 is an optical member (imaging optical system) that forms an image of the object to be imaged on the light receiving surface of the imaging element 110, or is at least a part of the optical member. The imaging element 110 converts the brightness of the image formed by the lens 111 into an amount of electric charge and outputs a signal (image signal) according to the amount of converted electric charge.

[0023] A filter unit 118 is disposed between the imaging element 110 and the lens 111. The filter unit 118 has a filter 118a supported by a support member such as a support frame, and a drive mechanism 118b that drives the filter 118a along the X-axis direction. The filter 118a has a first filter 191 and a second filter 192 that are arranged side by side along the X-axis direction (extension direction). The first filter 191 is an infrared cut filter that does not allow illumination light (infrared light) to enter the imaging element 110. The second filter 192 is a dummy lens or the like that allows illumination light (infrared light) to enter the imaging element 110.

[0024] The driving mechanism 118b has a driving unit such as a stepping motor, gears, guide rails, etc. The driving mechanism 118b is controlled by a control unit 31 (described later) to move the filter 118a along the extension direction, along the + or - side of the X-axis. In other words, the driving mechanism 118b is controlled by the control unit 31 to place either the first filter 191 or the second filter 192 on the optical axis L of the lens 111.

[0025] <Lighting Section 16> The illumination unit 16 is controlled by the control unit 31, and emits illumination light toward the imaging range of the camera module 11 to illuminate the subject when the external environment is dark. The illumination unit 16 is accommodated in the housing 12 and disposed on the Z-axis negative side of the illumination opening 126. The illumination unit 16 has a light source 161. The light source 161 has, for example, an LED chip and an optical member provided on the upper part of the LED chip, and emits light having a wavelength in the infrared range (infrared light, infrared light). When the imaging device 10 takes an image when the external environment is dark, the light source 161 emits infrared light as illumination light for illuminating the subject. Note that the light source 161 is not limited to emitting infrared light as illumination light, and may emit visible light other than infrared light as illumination light. The illumination light emitted from the light source 161 is fitted into the illumination opening 126 and emitted to the outside of the imaging device 10 through a covering member formed of, for example, a translucent resin or the like. 2, the imaging device 10 includes four illumination units 16 having the above-described configuration. Note that the number of illumination units 16 is not limited to four, and may be three or less, or five or more.

[0026] <Luminometer 17> The illuminometer 17 is, for example, a photoresistor or a photodiode, and receives light from the environment (external environment) surrounding the imaging device 10. The illuminometer 17 converts the brightness of the received light into an amount of charge and outputs a signal (brightness signal) according to the amount of charge. In other words, the illuminometer 17 detects the brightness of the environment surrounding the imaging device 10.

[0027] <Control Unit 31> The control unit 31 is configured with a CPU, a memory, etc., and is mounted on a board 31a disposed inside the housing 12. The control unit 31 is a processor that controls the operation of the camera module 11 and the illumination unit 16 by reading and executing a control program pre-recorded in a recording medium such as a flash memory. When performing an image capture process, the control unit 31 operates each unit by controlling the image capture mode according to either a normal image capture mode or a night vision mode. The normal image capture mode is an image capture mode that is set when the external environment of the image capture device 10 is bright. The night vision mode is an image capture mode that is set when the external environment of the image capture device 10 is dark and the amount of light is insufficient. In the night vision mode, the control unit 31 controls the illumination unit 16 to irradiate infrared light as illumination light, and causes the camera module 11 to capture an image of a subject illuminated by the infrared light.

[0028] In addition, the control unit 31 controls the lighting device 80 to receive power from a commercial power source via the power terminal 81 of the lighting device 80 when the lighting device 80 is operating (lit), and to receive power from the battery 70 when the lighting device 80 is not operating (off) (power supply processing).

[0029] The various processes executed by the control unit 31 will be described in detail later.

[0030] <Connection terminal 20> The connection terminal 20 is provided on a board 31b arranged in the housing 12, which is the main body, and is a connection terminal to which a power cable, a communication cable, etc. can be connected. More specifically, the connection terminal 20 is a USB terminal to which a USB cable can be connected. A board 50, which will be described later, is connected to the connection terminal 20. A switching circuit is provided on the board 31b, and a board 240 on which the internal power supply 24 is provided is electrically connected to a connector 25, which will be described later. The switching circuit is controlled by a control unit 31, which will be described later, and switches the source of power supply to the imaging device 10 between the illumination device 80, the internal power supply, and the battery 70.

[0031] <Connector 25> Connector 25 is a connection terminal to which a power cable, a communication cable, etc. can be connected. More specifically, connector 25 is a female USB terminal to which a USB cable 250 can be connected. Connector 25 faces a connector opening 121c provided in a side wall plate of rear case 121 on the negative side of the X-axis.

[0032] <Memory slot 26> The memory slot 26 is an attachment section in which a predetermined recording medium is detachably attached. More specifically, the imaging device 10 has a slot into which an SD memory card (hereinafter, referred to as a memory card 48) can be inserted and removed. When a cover provided on the side surface on the Y-axis + side of the rear case 121 is opened, the memory card 48 can be inserted and removed into the memory slot 26.

[0033] <Mounting part 40> The mounting part 40 has a mounting main body part 41 and a detachable part 42. The mounting main body part 41 has a plate-shaped mounting surface 410 parallel to the XY plane. The Z-axis + side of the mounting surface 410 is fixed to the bottom surface 121a formed on the rear case 121 of the housing 12 described above by screw connection.

[0034] The detachable part 42 is provided on the negative side of the Z axis of the attachment surface 410. The detachable part 42 is, for example, a ring-shaped member that corresponds to the outer circumferential shape of the lighting device 80, which is an external device. That is, when the imaging device 10 is attached to the lighting device 80, the detachable part 42 is formed in a shape that embraces a part of the lighting device 80 on the outer circumferential side.

[0035] However, the detachable part 42 has a notch formed by cutting out a part of the ring shape. The detachable part 42 is formed using an elastic material. Therefore, the imaging device 10 is attached to the lighting device 80 or detached from the lighting device 80 by moving the imaging device 10 along the Z axis. At this time, the notch is pushed open, so that the lighting device 80 reaches the ring-shaped interior of the detachable part 42 or moves away from the ring-shaped interior of the detachable part 42. Since the mounting part 40 has the above-mentioned configuration, the housing 12, which is a main body part, is fixed to the mounting part 40, and the mounting part 40 is detachably attached to the lighting device 80, which is an external device.

[0036] The detachable part 42 is not limited to having the above-mentioned shape. The detachable part 42 may be formed to have an appropriate shape according to the external shape of the whole or a part of the external device to which the imaging device 10 is to be attached or detached.

[0037] <Substrate 50> 3 is an external view of the substrate 50. The substrate 50 is a so-called flexible printed circuit board (FPC), and electrically connects a power terminal 81 of the illumination device 80 and a connection terminal 20 of the imaging device 10. The substrate 50 has a base portion 51, a contact portion 52, and a connection portion 53.

[0038] The base portion 51 is formed in a plate shape that expands in a direction intersecting the extension direction (X-axis direction) in which the power terminals 81 extend. Specifically, the base portion 51 is formed in a plate shape that is parallel or approximately parallel to the YZ plane. The base portion 51 is formed in a semicircular shape on the YZ plane. The semicircular base portion 51 has a side wall surface 502 that connects one end and the other end of an arcuate side wall surface 501 that is connected to the arcuate edge. The side wall surface 502 is a first side wall surface that is aligned along the arrangement direction (Y-axis direction) of the power terminals 81 when the board 50 and the power terminals 81 are connected.

[0039] The base portion 51 is provided with an accommodation portion 54 that accommodates the contact portion 52. The accommodation portion 54 is a through hole that penetrates the base portion 51 in the extension direction (X-axis direction). The accommodation portion 54 is a notch portion formed by cutting out a part of the side wall surface 502 toward the arcuate side wall surface 501.

[0040] The contact portion 52 is made of an elastic conductive material and is provided on the base portion 51. Specifically, the contact portion 52 is disposed in the above-mentioned housing portion 54. The number of the contact portions 52 (i.e., two) corresponds to the number of the pillar-shaped power supply terminals 81 of the lighting device 80. Therefore, the number of the housing portions 54 described above (two) corresponds to the number of the power supply terminals 81.

[0041] The contact portion 52 has a curved portion 521 that curves along the outer circumferential direction of the columnar power terminal 81 in the YZ plane intersecting with the extension direction, and an extension portion 522 that is connected to the curved portion 521 and extends to the Z-axis negative side. The curved portion 521 is formed by a first curved portion 521a that protrudes to the Y-axis positive side, and a second curved portion 521b that protrudes to the Y-axis negative side. The curved portion 521 (521a and 521b) is connected to the base portion 51 at an end portion on the Z-axis positive side, and is connected to the extension portion 522 (522a and 522b) at an end portion on the Z-axis negative side. On the Z-axis negative side, i.e., on the side of the side wall surface 502 that is the first side wall surface, the first curved portion 521a and the second curved portion 521b have a gap along the Y-axis direction that is the arrangement direction. Therefore, the extension portion 522 is also disposed with a gap in the Y-axis direction between the extension portion 522a and the extension portion 522b.

[0042] Since the contact portion 52 has the above-mentioned shape, when the imaging device 10 is attached to the lighting device 80, the curved portion 521 of the contact portion 52 comes into contact with a part of the outer periphery of the power terminal 81 of the lighting device 80. A gap is formed between the extension portions 522 on the negative Z-axis side of the contact portion 52. Therefore, when the board 50 is moved along the Z-axis direction when attaching or detaching the board 50 to or from the power terminal 81, the power terminal 81 pushes and spreads the extension portions 522 to reach or move away from the space surrounded by the curved portions 521. That is, the board 50 is attached to or detached from the power terminal 81 along a direction intersecting the Z-axis intersecting with the extension direction of the power terminal 81.

[0043] One side end of the connection part 53 is provided on the arc side wall surface 501, which is a second side wall surface different from the side wall surface 502, which is a first side wall surface. A connection terminal such as a USB terminal is attached to the other side end of the connection part 53. The connection part 53 is accommodated inside the housing 12 of the imaging device 10 through a board opening 121b formed in the housing 12, and is connected to a connection terminal 20 provided in the imaging device 10. That is, the connection part 53 is connected to the base part 51 and connected to the connection terminal 20. As a result, when the lighting device 80 is operating, power supplied from the commercial power source of the lighting device 80 is supplied to the imaging device 10 by the board 50 connected to the power terminal 81 of the lighting device 80.

[0044] <Cover part 60> The cover part 60 shown in Fig. 2 is made of a material with low conductivity such as an insulating material, and has a bottom surface 61 on the X-axis + side and is formed in a bottomed cylindrical shape that is open on the X-axis - side. The inner diameter of the cover part 60 is larger than the diameter of the lighting device 80, which is a straight fluorescent lamp. For this reason, the cover part 60 is detachably attached to the end of the lighting device 80 (the end on the X-axis + side in Figs. 1 and 2). In addition, since the above-mentioned board 50 is attached to the lighting device 80, when the cover part 60 is attached to the lighting device 80, the board 50 is accommodated inside the cover part 60.

[0045] A through hole 610 is formed in the bottom surface 61 of the cover part 60. The through hole 610 penetrates the bottom surface 61 from inside to outside along the X-axis. When the cover part 60 is attached to the end of the lighting device 80, the power terminal 81 of the lighting device 80 passes through the through hole 610 and protrudes outward from the bottom surface 61. A slit-shaped opening 620 is formed in the side surface 62 of the cover part 60. The connection part 53 of the board 50 described above passes through this opening 620 and is drawn outward and connected to the connection terminal 20. That is, the cover part 60 attached to the end of the lighting device 80 covers a part of the end of the lighting device 80 and a part of the board 50.

[0046] <Battery 70> 1, the battery 70 is detachably attached to an illumination device 80, which is an external device, and connected to an imaging device 10, which is an electronic device. The battery 70 includes a battery housing 71, which is a main body portion, a connector 72, and an attachment portion 73.

[0047] The battery housing 71 has a shape similar to that of the housing 12 of the imaging device 10. However, the opening 125 and the illumination opening 126 formed in the housing 12 are not formed in the battery housing 71. A secondary battery is provided inside the battery housing 71, which is capable of charging with power supplied from the commercial power source of the illumination device 80 via the imaging device 10 and supplying the charged power to the imaging device 10. Charging and discharging of the secondary battery are controlled by the control unit 31 of the imaging device 10.

[0048] The connector 72 is provided on a board disposed within the battery housing 71, and is a connection terminal to which a power cable, a communication cable, etc. can be connected. More specifically, the connector 72 is a USB terminal to which a USB cable 250 can be connected. The connector 72 is electrically connected to the connector 25 of the imaging device 10 via the USB cable 250.

[0049] The mounting portion 73 has a similar configuration to the mounting portion 40 of the imaging device 10. That is, the mounting portion 73 has a mounting main body portion 731 similar to the mounting main body portion 41, and a detachable portion 732 similar to the detachable portion 42. The bottom surface of the battery housing 71 is fixed to the mounting main body portion 731 by screw connection. In other words, the battery 70 is another example of an electronic device in which the battery housing 71, which is a main body portion, is detachably attached to the lighting device 80, which is an external device, by the mounting portion 73.

[0050] <Processing of control unit 31> Next, there will be described the processing performed by the control unit 31. The control unit 31 performs a photographing preparation processing, a photographing processing, and a power supply processing.

[0051] <Shooting preparation processing> As part of the photographing preparation process, the control unit 31 performs an amplification factor setting process that sets the amplification factor for the image signal generated during the photographing process, and a mode setting process that sets whether the photographing process will be performed in night vision mode or normal photographing mode.

[0052] <Amplification rate setting process> The control unit 31 calculates a luminance value based on the luminance signal output from the illuminometer 17, and sets an amplification factor for the image signal based on the calculated luminance value. In general, when the imaging device 10 captures an image in a dark external environment (night vision mode), the amount of light incident on the imaging element 110 is smaller than when the imaging device 10 captures an image in a bright external environment (normal imaging mode). For this reason, the control unit 31 sets the amplification factor to a higher value based on the calculated luminance value as the external environment becomes darker (i.e., the luminance value becomes lower).

[0053] Specifically, amplification factors corresponding to luminance values ​​(brightness of the external environment) are prepared in advance and recorded in advance in a recording medium such as a flash memory in the control unit 31 in table format, for example. The control unit 31 refers to this table and sets the amplification factor associated with the calculated luminance value as the amplification factor for the image signal. That is, the control unit 31 sets a value corresponding to the calculated luminance value from among values ​​predetermined for each brightness as the value of the amplification factor.

[0054] <Mode setting process> The control unit 31 determines that the external environment is bright when the amplification factor calculated based on the luminance signal output from the illuminometer 17 is equal to or less than a predetermined threshold, and determines that the external environment is dark when the amplification factor exceeds the threshold. The predetermined threshold is set based on the results of tests and simulations, and is recorded in advance in a recording medium such as a flash memory in the control unit 31.

[0055] When the calculated amplification rate exceeds the threshold value and the surrounding external environment is dark, the control unit 31 performs a process to enable shooting in the night vision mode. First, the control unit 31 controls the drive mechanism 118b of the filter unit 118 of the camera module 11 to move the first filter 191 away from the optical axis L of the lens 111 and place the second filter 192 on the optical axis L of the lens 111. This allows infrared light to enter the image sensor 110. Next, the control unit 31 causes the light source 161 of the illumination unit 16 to emit infrared light as illumination light.

[0056] When the calculated amplification rate is equal to or less than the threshold value and it is determined that the surrounding external environment is bright, the control unit 31 performs a process to enable shooting in the normal shooting mode. That is, the control unit 31 places the first filter 191 on the optical axis L of the lens 111. In addition, the control unit 31 does not allow the light source 161 to emit illumination light.

[0057] <Shooting process> The control unit 31 causes the image sensor 110 to receive subject light incident via the lens 111 and output an image signal. In the night vision mode, since the second filter 192 is positioned on the optical axis L of the lens 111, the image sensor 110 receives light reflected by the subject out of the illumination light emitted from the light source 161 and outputs an image signal.

[0058] The control unit 31 performs known image processing, including, for example, AD conversion processing, signal amplification processing, white balance processing, etc., on the image signal output from the image sensor 110 to generate image data. At this time, the control unit 31 amplifies the image signal at the amplification rate set in the above-mentioned shooting preparation processing. Then, the control unit 31 records the generated image data in the memory card 48.

[0059] Thereafter, the control unit 31 sets the value of the amplification factor based on the generated image data, whether in the normal shooting mode or the night vision mode. The control unit 31 generates image data using the set value of the amplification factor. That is, the amplification factor for the image signal is controlled by auto gain control (AGC). In this case, the control unit 31 sets the amplification factor by either one of the first control and the second control described below, or by appropriately switching between the first control and the second control.

[0060] In the first control, the control unit 31 sets the amplification factor using correction data (correction table) created by calculating the value of the amplification factor based on image data generated under a test environment. This correction data is obtained by associating a plurality of amplification factor values ​​calculated using image data generated under a test environment with different external environmental brightnesses with the luminance of the image data. This correction data is recorded in a recording medium such as a flash memory in the control unit 31. Based on the luminance of the image data generated by the shooting process, the control unit 31 reads out the corresponding amplification factor value from the correction data and sets it as the amplification factor value.

[0061] In the second control, the control unit 31 stores the value of the amplification factor calculated based on image data generated in the installation environment of the imaging device 10, and sets the amplification factor as desired. When executing the first control or the second control, the control unit 31 can also set the amplification factor using the result of learning, by AI or the like, the value of the amplification factor calculated and stored based on image data.

[0062] <Power supply processing> As described above, when the lighting device 80 is operating, power supplied from the commercial power supply of the lighting device 80 is supplied to the imaging device 10 by the board 50 via the power terminal 81 in contact with the contact portion 52. That is, when the lighting device 80 is operating, the imaging device 10 operates with power supplied from the commercial power supply of the lighting device 80 (normal power supply mode). Also, when the lighting device 80 is not operating, the imaging device 10 operates with power supplied from the battery 70, which is another electronic device (external power supply mode). The control unit 31 switches the power supply source of the imaging device 10 at the timing when the lighting device 80 switches between operating and non-operating. This will be described in detail below.

[0063] <Switching from normal power mode to external power mode> Switching from the normal power supply mode to the external power supply mode is executed by the control unit 31 when the power supply to the illumination device 80 is turned off while the imaging device 10 is performing an image capturing process. When the control unit 31 detects that the power supply to the illumination device 80 is turned off and power supply via the board 50 is no longer performed, it temporarily switches the power supply source to the internal power supply 24.

[0064] When switching to the external power supply mode, the control unit 31 checks whether the current supplied from the battery 70 is stable. Specifically, the control unit 31 measures the value of the current supplied from the battery 70 via the connector 25, and checks whether it is a preset steady current value. When the measured current value reaches the steady current value, the control unit 31 switches the power supply source to the battery 70. Thereafter, the imaging device 10 switches to the external power supply mode in which the imaging device 10 operates using power supplied from the battery 70. Note that while the control unit 31 is checking whether the measured current value reaches the steady current value, it is not necessary to perform operations that consume a lot of power, such as restricting communication of a wireless communication module (not shown) or switching to a night vision mode.

[0065] Incidentally, the switching from the normal power supply mode to the external power supply mode may be performed automatically in response to the power off of the lighting device 80 (automatic switching), or in response to an instruction from the user after the power off of the lighting device 80 (manual switching). Alternatively, the automatic switching and the manual switching may be configured to be selectable by the user. In the case of manual switching, an alarm (sound, flashing of the illumination light) or the like may be issued to prompt the user to perform a manual switching operation in response to the power off of the lighting device 80. In addition, in the case of manual switching, when the user performs a switching operation such as operating a changeover switch (not shown) provided on a remote control or the like, the control unit 31 may switch to the external power supply mode. When the imaging device 10 switches to the external power supply mode, the control unit 31 performs the above-mentioned shooting preparation processing and imaging processing.

[0066] The switching process from the normal power supply mode to the external power supply mode performed by the control unit 31 will be described with reference to the flowcharts shown in Figures 4 and 5. Each process shown in the flowchart is performed by the control unit 31 reading a program recorded in a recording medium such as a flash memory when it is detected that the power supply of the lighting device 80 has been turned off, and the control unit 31 executing the program. Note that the following description is of the process when the power supply of the lighting device 80 is turned off while the imaging device 10 is performing an image capture process.

[0067] 4, the control unit 31 confirms that power is not being supplied from the battery 70, and the process proceeds to step S2. In step S2, the control unit 31 switches the power supply source to the internal power source 24. As a result, power is temporarily supplied from the internal power source 24 to each device in the imaging device 10. Thereafter, the process proceeds to step S3.

[0068] In step S3, the control unit 31 judges whether the switching between the normal power supply mode and the external power supply mode is set to automatic switching. If it is set to automatic switching, the control unit 31 makes a positive judgment and the process proceeds to step S5 described later. If it is set to manual switching, the control unit 31 makes a negative judgment and the process proceeds to step S4.

[0069] In step S4, the control unit 31 determines whether or not a switching operation has been performed by the user. If a switching operation has been performed, the control unit 31 makes a positive determination and the process proceeds to step S5. If a switching operation has not been performed, the control unit 31 makes a negative determination and repeats the process of step S4.

[0070] In step S5, the control unit 31 sets the power supply source to the battery 70. After that, the process proceeds to step S6. In step S6, the control unit 31 checks whether the current supplied from the battery 70 is stable. As described above, the control unit 31 measures the value of the current supplied from the battery 70 via the connector 25, and when it checks that the current value has reached a steady current value, it switches the power supply source to the battery 70. After that, the process proceeds to step S7.

[0071] In step S7, the control unit 31 calculates the luminance value of the external environment based on the luminance signal output from the illuminometer 17, and calculates the amplification factor based on this luminance value. After that, the process proceeds to step S8. In step S8, the control unit 31 determines whether or not to switch to the night vision mode based on the calculated amplification factor. If the amplification factor exceeds the threshold and the external environment is dark, the control unit 31 makes a positive determination, and the process proceeds to step S9. If the amplification factor is equal to or less than the threshold and the external environment is bright, the control unit 31 makes a negative determination, and the process proceeds to step S11 shown in FIG. 5, which will be described later.

[0072] In step S9, the control unit 31 controls the drive mechanism 118b included in the filter unit 118 of the camera module 11 to place the second filter 192 on the optical axis L of the lens 111. Then, the process proceeds to step S10. In step S10, the control unit 31 causes the light source 161 to emit illumination light. Then, the process proceeds to step S11 shown in FIG.

[0073] 5, the control unit 31 causes the image sensor 110 to receive subject light incident via the lens 111 and output an image signal. Then, the control unit 31 performs various image processes on the image signal output from the image sensor 110 to generate image data, and records the generated image data on the memory card 48. After that, the process proceeds to step S12.

[0074] In step S12, the control unit 31 calculates a new gain value by controlling with AGC based on the generated image data. Then, the control unit 31 sets the calculated new gain value as the gain value to be used when generating image data. After that, the process proceeds to step S13. In step S13, the control unit 31 determines whether or not the sensitivity of the image sensor 110 is appropriate. If the sensitivity of the image sensor 110 is appropriate, the control unit 31 makes a positive determination and ends the series of processes. If the sensitivity of the image sensor 110 is not appropriate, the control unit 31 makes a negative determination and the process returns to step S12.

[0075] When operating in the external power supply mode, the control unit 31 may not emit illumination light from the light source 161 or may emit illumination light at a low output when shooting in the night vision mode. When illumination light is not emitted from the light source 161, the control unit 31 does not perform the above step S10. This makes it possible to suppress an increase in power consumption of the imaging device 10 in the external power supply mode.

[0076] Furthermore, when switching from the normal power supply mode to the external power supply mode, the control unit 31 may stop the photographing process. That is, the control unit 31 may not generate an image signal by the image sensor 110, generate image data based on the image signal, and record the generated image data in the memory card 48. In this case, the control unit 31 may stop the photographing process after the process of step S4 in the flowchart shown in FIG. 4. At this time, the control unit 31 may restart the imaging device 10 after setting the power supply source to the battery 70 in step S5. In this case, if automatic switching was set before the restart, the control unit 31 restarts the imaging device 10 while receiving power from the battery 70.

[0077] By the control unit 31 performing the above-mentioned processing, even if the illumination device 80 is turned off, the imaging device 10 can receive power from the battery 70. That is, even if the illumination device 80 is turned off, the imaging device 10 can continue the photographing process.

[0078] <Switching from external power mode to normal power mode> Switching from the external power supply mode to the normal power supply mode is executed by the control unit 31 when the power supply of the illumination device 80 is turned on while the imaging device 10 receiving power supply from the battery 70 is performing an imaging process. When the control unit 31 detects that the power supply of the illumination device 80 is turned on and power supply via the board 50 has started, the control unit 31 stops the imaging process. In other words, the control unit 31 does not generate an image signal by the imaging element 110, does not generate image data based on the image signal, and does not record the generated image data in the memory card 48.

[0079] Then, when switching to the normal power supply mode, the control unit 31 checks whether the current supplied through the board 50 is stable. Specifically, the control unit 31 measures the value of the current supplied through the board 50 and checks whether it is a preset steady-state current value. When the measured current value reaches the steady-state current value, the control unit 31 switches the power supply source to the commercial power source of the lighting device 80 connected to the board 50. At this time, the control unit 31 may restart the imaging device 10 after setting the power supply source to the commercial power source of the lighting device 80. At this time, if automatic switching was set before the restart, the control unit 31 restarts the imaging device 10 while receiving power from the commercial power source of the lighting device 80.

[0080] Thereafter, the imaging device 10 switches to a normal power supply mode in which it operates using power supplied via the power supply terminal 81 of the lighting device 80. Note that while the control unit 31 is checking whether the measured current value is a steady current value, it is not necessary for it to perform operations that consume a lot of power, such as restricting communication of a wireless communication module (not shown) or switching to a night vision mode. When the imaging device 10 switches to the normal power supply mode, the control unit 31 performs the above-mentioned shooting preparation process and shooting process. Also, when the imaging device 10 operates in the normal power supply mode, the control unit 31 charges the battery 70 with power supplied from the commercial power supply of the lighting device 80 via the board 50.

[0081] The switching process from the external power supply mode to the normal power supply mode performed by the control unit 31 will be described with reference to the flowcharts shown in Figures 6 and 7. Each process shown in the flowchart is performed by the control unit 31 reading a program recorded in a recording medium such as a flash memory when it is detected that the power supply of the lighting device 80 is turned on, and the control unit 31 executing the program. Note that the following description is of the process when the power supply of the lighting device 80 is turned on while the imaging device 10 is performing an image capture process.

[0082] In step S21, the control unit 31 confirms that power is being supplied from the battery 70, and the process proceeds to step S22. In step S22, the control unit 31 stops the photographing process. That is, the output of the image signal by the imaging element 110, the generation of image data based on the image signal, and the recording of the generated image data to the memory card 48 are stopped. The process then proceeds to step S23.

[0083] In step S23, the control unit 31 sets the power supply source to the commercial power source of the lighting device 80. Then, the process proceeds to step S24. In step S24, the control unit 31 checks whether the current supplied via the board 50 is stable. As described above, the control unit 31 measures the value of the current supplied via the board 50, and when it checks that the current value has reached a steady current value, it switches the power supply source to the commercial power source of the lighting device 80. Then, the process proceeds to step S25.

[0084] Each process from step S25 (calculating the brightness value of the external environment) to step S31 (determining whether the sensitivity of the image sensor 110 is appropriate) shown in FIG. 7 is the same as each process from step S7 (calculating the brightness value of the external environment) shown in FIG. 4 to step S13 (determining whether the sensitivity of the image sensor 110 is appropriate) shown in FIG. 5. In step S32 following step S31, the control unit 31 checks whether the battery 70 is connected to the image sensor 10. At this time, the control unit 31 outputs a request signal to the battery 70 via the USB cable 250 connected to the connector 25. If the battery 70 is connected to the image sensor 10, that is, if the control unit 31 inputs a response signal to the request signal, the control unit 31 makes an affirmative determination, and the process proceeds to step S33. If the battery 70 is not connected to the image sensor 10, that is, if the control unit 31 does not input a response signal to the request signal, the control unit 31 makes a negative determination, and the process ends.

[0085] In step S33, the control unit 31 supplies the power supplied via the board 50 to the battery 70 via the USB cable 250 connected to the connector 25, and starts charging the battery 70. After that, the control unit 31 ends the series of processes.

[0086] According to the above-described first embodiment, at least one of the following advantageous effects can be obtained.

[0087] (1) The imaging device 10, which is an electronic device, includes a housing 12, which is a main body, an attachment portion 40 that is fixed to the housing 12 and is detachably attached to a lighting device 80, which is an external device, and a board 50. The board 50 is detachably attached to a power terminal 81 provided on the lighting device 80, and electrically connects the connection terminal 20 and the power terminal 81. The imaging device 10 is supplied with power through the board 50 connected to the power terminal 81 of the lighting device 80. This makes it possible to detachably attach the imaging device 10, which is supplied with power from the commercial power source of the lighting device 80, to the lighting device 80, which is an external device. As a result, when the imaging device 10 needs to be inspected, maintained, replaced, or the like, it is no longer necessary to remove the imaging device from the lighting device after removing the entire lighting device, as in the case where the imaging device is built into the lighting device, and therefore workability is improved. Also, unlike the case where the imaging device is built into the lighting device, even if no abnormality occurs in the imaging device 10, when the lighting device 80 is discarded, the imaging device 10, which is not abnormal, is not discarded together with the lighting device 80. Furthermore, the process of incorporating the imaging device 10 into the lighting device 80 during manufacturing becomes unnecessary, and productivity can be improved.

[0088] (2) The base portion 51 of the substrate 50 is provided with an accommodation portion 54 for accommodating the contact portion 52, and the accommodation portion 54 penetrates the base portion 51 along the extension direction. This allows the contact portion 52 to be connected to the power supply terminal 81 to be provided on the base portion 51, so that the imaging device 10 can be supplied with power via the substrate 50.

[0089] (3) The substrate 50 is detachable along a direction intersecting the extension direction of the power terminals 81. Specifically, the base portion 51 has a side wall surface 502 that is a first side wall surface along the arrangement direction in which the multiple power terminals 81 are arranged. The accommodation portion 54 is a cutout portion formed by cutting out a part of the side wall surface 502. This allows the substrate 50 to be attached to and detached from the power terminals 81 without removing the lighting device 80, improving convenience.

[0090] (4) The contact portion 52 is provided with a first curved portion 521a and a second curved portion 521b that are curved along the outer circumferential direction of the power terminal 81 in a YZ plane intersecting with the extension direction, and the first curved portion 521a and the second curved portion 521b have a gap along the arrangement direction (Y-axis direction) on the side wall surface 502 side. This allows the power terminal 81 to pass through the gap between the first curved portion 521a and the second curved portion 521b, thereby making it possible to attach and detach the board 50 to the power terminal 81. In addition, when the board 50 is attached to the power terminal 81, contact between the contact portion 52 and the power terminal 81 is maintained, and the board 50 is prevented from falling off the power terminal 81.

[0091] (5) Connection portion 53 is provided on arcuate side wall surface 501, which is a second side wall surface different from side wall surface 502, which is a first side wall surface. This makes it possible to attach substrate 50 to power terminal 81 without interference from connection portion 53.

[0092] (6) The imaging device 10 includes a cover 60 made of an insulating material that covers the substrate 50 and at least a part of the power terminal 81. This prevents dust and other particles from entering the device, and can prevent short-circuiting and other accidents from occurring.

[0093] <Second embodiment> An imaging device, which is an electronic device of the second embodiment, will be described below. In the following description, the same components as those of the first embodiment are given the same reference numerals, and differences will be mainly described. Points that are not particularly described are the same as those of the first embodiment. The substrate of the imaging device of the second embodiment is different from that of the first embodiment.

[0094] 8 is a perspective view of the appearance of a substrate 90 included in the imaging device 10 of the second embodiment. The substrate 90 is a so-called flexible printed circuit board (FPC), and includes a base portion 91, a contact portion 92, and a connection portion 93.

[0095] The base portion 91 is formed in a plate shape that expands in a direction intersecting the extension direction (X-axis direction) in which the power terminals 81 extend. That is, the base portion 91 is formed in a plate shape that is parallel or approximately parallel to the YZ plane. The base portion 91 is formed in a circular shape on the YZ plane. The base portion 91 is formed with a storage portion 94 that is a through hole that penetrates the base portion 91 in the X-axis direction (extension direction). When the board 90 is attached to the lighting device 80, the power terminals 81 of the lighting device 80 are inserted into the storage portion 94. For this reason, the number of storage portions 94 formed corresponds to the number of power terminals 81 (two).

[0096] The contact portion 92 is made of an elastic conductive material and is housed in the housing portion 94. The number of contact portions 92 (i.e., two) corresponds to the number of pillar-shaped power supply terminals 81 included in the lighting device 80. One of the two contact portions, 92a, is formed in an annular shape corresponding to the outer periphery of the pillar-shaped power supply terminal 81.

[0097] The remaining one of the two contact portions 92b is formed by a curved portion 921 that curves along the outer circumferential direction of the power supply terminal 81 in a plane (YZ plane) intersecting with the extension direction, two extension portions 922 that connect to the curved portion 921, and a connection contact portion 923 that connects the two extension portions 922. The two extension portions 922 extend toward the contact portion 92a along the Y-axis direction, which is the arrangement direction. The contact portion 92b has the extension portion 922, so that an installation error when the substrate 90 is attached to the lighting device 80 can be absorbed.

[0098] Since the contact portion 92 and the accommodating portion 94 have the above-mentioned shapes, the substrate 90 is attached to and detached from the power supply terminal 81 by moving the substrate 90 along the X-axis direction. That is, the substrate 90 is attached to and detached from the power supply terminal 81 along the extension direction of the power supply terminal 81.

[0099] One end of the connection portion 93 is formed on a side wall surface of the base portion 91, and a connection terminal such as a USB terminal is attached to the other end. The connection portion 93 is accommodated inside the housing 12 of the imaging device 10 through a board opening 121b formed in the housing 12, and is connected to the connection terminal 20 provided in the imaging device 10. Thus, also in the second embodiment, when the lighting device 80 is operating, power supplied from the commercial power source of the lighting device 80 is supplied to the imaging device 10 by the board 90 through the power terminal 81 in contact with the contact portion 92.

[0100] In the second embodiment, the control unit 31 performs the same processing as that described in the first embodiment. That is, the control unit 31 performs the processing for switching to the external power supply mode shown in Fig. 4 and Fig. 5, and the processing for switching to the normal power supply mode shown in Fig. 6 and Fig. 7.

[0101] According to the second embodiment described above, in addition to the effects (1), (2), and (6) obtained by the first embodiment, the following effects can be obtained.

[0102] (7) The substrate 90 is detachable along the extension direction of the power supply terminal 81. This makes it possible to attach the substrate 90 to the power supply terminal 81 while preventing the substrate 90 from falling off the power supply terminal 81.

[0103] (8) At least one contact portion 92b of the multiple contact portions 92 is provided with a curved portion 921 that curves along the outer circumferential direction of the power terminal 81 in the YZ plane intersecting with the extension direction, and an extension portion 922 that is connected to the curved portion 921 and extends along the arrangement direction. This makes it possible to absorb installation errors that may occur when the substrate 90 is attached to the lighting device 80.

[0104] Although various embodiments and modifications have been described above, the present invention is not limited to these. Other embodiments that are conceivable within the scope of the technical idea of ​​the present invention are also included within the scope of the present invention.

[0105] The battery 70 does not have to be attached to the lighting device 80 by the attachment portion 73. For example, the battery 70 may be disposed between the attachment surface 410 of the attachment portion 40 of the imaging device 10 and the rear case 121 of the housing 12. Alternatively, the imaging device 10 does not have to be connected to the battery 70, which is another electronic device. In this case, when the lighting device 80 is not operating, the control unit 31 causes the internal power source 24 to supply power to each device in the imaging device 10.

[0106] Further, the present invention is not limited to a configuration in which a connection terminal is provided at an end of the connection portion 53 of the substrate 50 and connected to the connection terminal 20 of the substrate 31b. For example, instead of the connection terminal at the end of the connection portion 53, a lead wire may be attached and connected to the connection terminal 20. Alternatively, a connection terminal at the end of the connection portion 53 may be connected to a lead wire and connected to the connection terminal 20.

[0107] Furthermore, the imaging device 10 may have a shutter that is driven to be able to close and open the lens 111. In this case, the shutter may be attached on the Z axis + side of the lens 111 so as to be able to move along the X axis direction (extension direction).

[0108] Furthermore, the electronic device is not limited to the imaging device 10, and may be, for example, a wireless communication device that performs various wireless communications. In this case, the wireless communication device may be a wireless communication device that serves as a relay station that relays information between a plurality of communication devices.
