[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0013] 1 is a diagram showing a schematic configuration of an electronic device 1 including an imaging control device 3 that is an embodiment of the imaging control device of the present invention. The electronic device 1 is an electronic device with an imaging function, such as a digital camera, a tablet terminal with a camera, or a smartphone with a camera.

[0014] The electronic device 1 includes an imaging optical system 2 including a lens, an aperture, etc., and an imaging control device 3 including an imaging element 21 (see FIG. 2) that captures an image of a subject through the imaging optical system 2. Hereinafter, the direction along the optical axis K of the imaging optical system 2 will be referred to as direction Z. Furthermore, two directions that are perpendicular to direction Z and perpendicular to each other will be referred to as direction X and direction Y.

[0015] The imaging control device 3 includes an imaging control board 10, an imaging board 20 on which an imaging element 21 such as a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal Oxide Semiconductor) image sensor is mounted, an anti-shake unit 30, and flexible printed circuit boards (hereinafter referred to as FPC boards) FS1 and FS2. The imaging board 20 and imaging control board 10 are electrically connected by the FPC board FS1. The anti-shake unit 30 and imaging control board 10 are electrically connected by the FPC board FS2. Note that the anti-shake unit 30 and FPC board FS2 are not essential to the imaging control device 3 and may be omitted.

[0016] The vibration isolation unit 30 moves the imaging board 20 including the imaging element 21 in a plane perpendicular to the optical axis K of the imaging optical system 2, thereby preventing blurring of the subject image formed on the imaging element 21.

[0017] The imaging board 20, the vibration isolation unit 30, and the imaging control board 10 are arranged side by side in the Z direction in this order from the imaging optical system 2 side.

[0018] The imaging board 20 is a plate-shaped board perpendicular to the direction Z. Of both end faces of the imaging board 20 in the direction Z, the face on the imaging optical system 2 side is referred to as the main surface 20a. The imaging control board 10 is a plate-shaped board perpendicular to the direction Z. Of both end faces of the imaging control board 10 in the direction Z, the face opposite the imaging optical system 2 side is referred to as the main surface 10a.

[0019] The FPC board FS1 is a flexible board including a plurality of conducting wires and is configured in an elongated shape. The FPC board FS1 has plugs that are connected to an imaging board connector provided on the main surface 20a of the imaging board 20 and a control board connector provided on the main surface 10a of the imaging control board 10. As shown in Fig. 2, the FPC board FS1 is folded back from the main surface 20a of the imaging board 20 toward the main surface 10a of the imaging control board 10, electrically connecting the imaging board connector and the control board connector.

[0020] The FPC board FS2 is a flexible board including multiple conductive wires and is configured in a long shape. The FPC board FS2 has FPC plugs that are connected to an anti-vibration unit connector provided on the anti-vibration unit 30 and a control board connector provided on the main surface 10a of the imaging control board 10. As shown in Fig. 2, the FPC board FS2 is folded back from the anti-vibration unit 30 toward the main surface 10a of the imaging control board 10, electrically connecting the anti-vibration unit connector and the control board connector.

[0021] Fig. 2 is a schematic diagram showing a detailed configuration example of the imaging board 20, imaging control board 10, and FPC board FS1 in the imaging control device 3 shown in Fig. 1. Fig. 2 shows a state in which the FPC board FS1 is unfolded so that the main surface 20a of the imaging board 20 and the main surface 10a of the imaging control board 10 face in the same direction.

[0022] The main surface 20a of the imaging board 20 is provided with an imaging element 21, a first imaging board connector 22, a second imaging board connector 23, and a third imaging board connector 24. The imaging element 21 is formed as a chip and has multiple terminals. The terminals of the imaging element 21 include multiple power supply terminals for receiving power from the imaging control board 10, multiple control terminals for receiving control signals from the imaging control board 10, and multiple output terminals for outputting imaging signals, etc.

[0023] The first imaging board connector 22 includes terminals connected to each of the multiple power supply terminals of the imaging element 21. The second imaging board connector 23 includes terminals connected to each of the multiple control terminals of the imaging element 21. The third imaging board connector 24 includes terminals connected to each of the multiple output terminals of the imaging element 21.

[0024] A plurality of differential signal transmission lines, each consisting of a pair of two signal lines, employing a transmission method such as LVDS (Low Voltage Differential Signal), are connected to a plurality of output terminals of the imaging element 21. The other ends of these differential signal transmission lines are respectively connected to terminals included in the third imaging board connector 24. As an example, the imaging element 21 is provided with 32 output terminals. In other words, the output terminals of the imaging element 21 and the terminals of the third imaging board connector 24 are connected by a wiring group consisting of 16 differential signal transmission lines. In addition to LVDS, other transmission methods such as MIPI (Mobile Industry Processor Interface) (registered trademark) and SLVS-EC (Scalable Low Voltage Signaling with Embedded Clock) (registered trademark) may also be used.

[0025] The main surface 10a of the imaging control board 10 is provided with a chip-based processor 11, a chip-based power control circuit 12, a first control board connector 13, a second control board connector 14, a third control board connector 15, and a fourth control board connector 16.

[0026] The processors described in this specification include a CPU (Central Processing Unit), which is a general-purpose processor that executes programs to perform various processes, a programmable logic device (PLD), which is a processor whose circuit configuration can be changed after manufacture, such as an FPGA (Field Programmable Gate Array), or a dedicated electric circuit, such as an ASIC (Application Specific Integrated Circuit), which is a processor having a circuit configuration designed specifically for performing specific processes. More specifically, the structure of a processor is an electric circuit that combines circuit elements such as semiconductor elements.

[0027] The power control circuit 12 controls the supply of power generated by a power supply circuit (not shown) built into the electronic device 1 to the imaging board 20. The power control circuit 12 includes a terminal group 12A consisting of a plurality of power control terminals for connection to the imaging board 20. The first control board connector 13 includes terminals connected to the power control terminals of the power control circuit 12. The power control terminals of the power control circuit 12 and the terminals of the first control board connector 13 are connected by a wiring group 13A provided on the imaging control board 10.

[0028] The processor 11 controls the image sensor 21 and the vibration isolation unit 30. Specifically, the processor 11 transmits a control signal for driving the image sensor 21 to the image sensor 21 to control imaging, transmits a control signal for driving the vibration isolation unit 30 to the vibration isolation unit 30 to control vibration, and acquires an output signal from the image sensor 21 and processes the output signal.

[0029] The processor 11 includes a terminal group 11A consisting of a plurality of control signal output terminals for outputting control signals that control the imaging element 21, and a terminal group 11B consisting of a plurality of differential signal input terminals for inputting output signals from the imaging element 21. The plurality of control signal output terminals included in the terminal group 11A are arranged in direction Y. The plurality of differential signal input terminals included in the terminal group 11B are arranged in direction X. In this embodiment, as an example, it is assumed that the number of differential signal input terminals included in the terminal group 11B is 32.

[0030] Each control signal output terminal included in the terminal group 11A of the processor 11 and each terminal of the second control board connector 14 are connected by a wiring group 14A provided on the imaging control board 10.

[0031] A part of all the differential signal input terminals included in the terminal group 11B of the processor 11 and each terminal of the third control board connector 15 are connected by a wiring group 15A provided on the imaging control board .

[0032] The remaining differential signal input terminals other than the above-mentioned portion of all the differential signal input terminals included in the terminal group 11B of the processor 11 and each terminal of the fourth control board connector 16 are connected by a wiring group 16A provided on the imaging control board 10.

[0033] In this embodiment, as an example, the number of terminals of third control board connector 15 is 16, and the number of terminals of fourth control board connector 16 is 16. Therefore, the total number of differential signal transmission lines that can be connected to third control board connector 15 and fourth control board connector 16 is eight.

[0034] The arrangement direction of the multiple terminals included in third control board connector 15 is direction X. Furthermore, the arrangement direction of the multiple terminals included in fourth control board connector 16 is direction X. In other words, the arrangement direction of the multiple terminals included in third control board connector 15 is the same as the arrangement direction of the differential signal input terminals of processor 11 connected to these multiple terminals by wiring group 15A. Similarly, the arrangement direction of the multiple terminals included in fourth control board connector 16 is the same as the arrangement direction of the differential signal input terminals of processor 11 connected to these multiple terminals by wiring group 16A.

[0035] In this way, by making the arrangement direction of the multiple terminals included in the third control board connector 15 (fourth control board connector 16) the same as the arrangement direction of the differential signal input terminals of the processor 11 connected to these multiple terminals, it is possible to facilitate the routing of the wiring group 15A (wiring group 16A) and reduce the manufacturing cost of the imaging control board 10.

[0036] The FPC board FS1 that electrically connects the imaging control board 10 and the imaging board 20 includes a first FPC board F1, a second FPC board F2, and a third FPC board F3.

[0037] The first FPC board F1 connects each terminal of the first control board connector 13 of the imaging control board 10 to each terminal of the first imaging board connector 22 of the imaging board 20. In other words, each conductor included in the first FPC board F1 serves as a power supply line that supplies power controlled by the power control circuit 12 of the imaging control board 10 to the imaging board 20.

[0038] The second FPC board F2 connects each terminal of the second control board connector 14 of the imaging control board 10 to each terminal of the second imaging board connector 23 of the imaging board 20. In other words, each conductor included in the second FPC board F2 serves as a control signal line that transmits a control signal output from the processor 11 of the imaging control board 10 to the imaging board 20.

[0039] The third FPC board F3 connects each terminal of the third control board connector 15 and each terminal of the fourth control board connector 16 of the imaging control board 10 to each terminal of the third imaging board connector 24 of the imaging board 20. In other words, each conductor included in the third FPC board F3 is a differential signal transmission line that transmits the output signal of the imaging element 21 to the imaging control board 10. In the above example, the number of differential signal transmission lines included in the third FPC board F3 is 16. The number of terminals included in the connector 16, which includes transmission lines for GND and clock signals in addition to the 16 differential signal transmission lines, is 56 for the LVDS system and 50 for SLVS-EC.

[0040] The electronic device 1 configured as described above is manufactured in a number of models, each with a different configuration of the imaging control device 3. Even when the model of the electronic device 1 is different, the configuration of the imaging control board 10 is the same. Fig. 3 is a schematic diagram corresponding to Fig. 2, which shows the configuration of another model of the electronic device 1 shown in Fig. 1. Fig. 3 has the same configuration as Fig. 2, except that the imaging board 20 is changed to an imaging board 20A, and the FPC board FS1 is changed to an FPC board FS3.

[0041] 3 includes an imaging element 21A, a fourth imaging element connector 22A, and a fifth imaging element connector 23A. The imaging element 21A requires a different power supply current for operation than the imaging element 21. Specifically, the power supply current required for operation of the imaging element 21A is smaller than the power supply current required for operation of the imaging element 21. Furthermore, the imaging element 21A has fewer output terminals than the imaging element 21. As an example, the number of output terminals included in the imaging element 21A is half the number of output terminals of the imaging element 21, i.e., 16.

[0042] The terminals of the fourth imaging board connector 22A are connected to a plurality of power supply terminals and a plurality of control terminals included in the imaging element 21 A. The terminals of the fifth imaging board connector 23A are connected to a plurality of output terminals included in the imaging element 21 A.

[0043] The FPC board FS3 includes a fourth FPC board F4 and a fifth FPC board F5.

[0044] The fourth FPC board F4 connects each terminal of the first control board connector 13 and each terminal of the second control board connector 14 of the imaging control board 10 to each terminal of the fourth imaging board connector 22A of the imaging board 20A. In other words, the group of conductors included in the fourth FPC board F4 is made up of power supply lines that supply power controlled by the power control circuit 12 of the imaging control board 10 to the imaging board 20A, and control signal lines that transmit control signals output from the processor 11 of the imaging control board 10 to the imaging board 20A.

[0045] The power supply current required for operation of imaging element 21A is smaller than the power supply current required for operation of imaging element 21. Meanwhile, power control circuit 12 is common to both Figures 2 and 3, and the power output from first control board connector 13 is the same in Figures 2 and 3. Therefore, so that a power supply current of a magnitude appropriate for imaging element 21A is supplied to imaging element 21A, the electrical resistance value of the power supply line included in fourth FPC board F4 is configured to be greater than the electrical resistance value of the power supply line included in first FPC board F1 shown in Figure 2. Specifically, the power supply line included in fourth FPC board F4 is thinner than the power supply line included in first FPC board F1 shown in Figure 2.

[0046] The fifth FPC board F5 connects each terminal of the third control board connector 15 to each terminal of the fifth imaging board connector 23A. In other words, each conductor included in the fifth FPC board F5 serves as a differential signal transmission line that transmits the output signal of the imaging element 21A to the imaging control board 10. In the above example, the number of differential signal transmission lines included in the fifth FPC board F5 is eight.

[0047] In the electronic device 1 of the model shown in FIG. 3, the fourth control board connector 16 of the imaging control board 10 is not used. Therefore, no wiring is connected to the fourth control board connector 16, or a plug that shorts the terminals of the fourth control board connector 16 is attached. Therefore, in the electronic device 1 of the model shown in FIG. 3, the output signal of the imaging element 21A is input to only 16 of the 32 differential signal input terminals of the processor 11. The program stored in the memory of the processor 11 is a program that differs for each model. This eliminates the need to change the imaging control board 10 even if the electronic device 1 is of a different model.

[0048] As described above, the configuration of the imaging board differs for each model of electronic device 1, and the power supply current required to operate the imaging element mounted on that imaging board also differs. Therefore, the allowable current value (maximum current value that can flow) of the first control board connector 13 of the imaging control board 10 is set to the same value as the power supply current required to operate the imaging element that requires the greatest power supply current among all imaging elements mounted on all models of electronic device 1. This allows imaging elements that differ for each model to be connected to the imaging control board 10 and the supplied power to be controlled normally.

[0049] As described above, according to the electronic device 1, there is no need to change the configuration of the imaging control board 10 for each model, thereby reducing manufacturing costs. In the imaging control board 10, the third control board connector 15 and the fourth control board connector 16 are dedicated connectors for connecting differential signal transmission lines. Therefore, even if the imaging element requires a different number of differential signal transmission lines, it is possible to connect the imaging element and the processor 11 simply by changing the number of differential signal transmission lines connected to these dedicated connectors. Therefore, there is no need to optimize the configuration of the imaging control board 10 for each different imaging element, thereby reducing manufacturing costs of the imaging control board 10.

[0050] In the imaging control board 10, the first control board connector 13 is a connector dedicated to connecting a power supply line, and the second control board connector 14 is a connector dedicated to connecting a control signal line. Even if the first control board connector 13 and the second control board connector 14 are integrated into a single connector, changing the configuration of the FPC board connected to the connector eliminates the need to optimize the configuration of the imaging control board 10 for each imaging element. However, providing the first control board connector 13 and the second control board connector 14 separately facilitates routing of the wiring groups 13A and 14A, thereby reducing the manufacturing cost of the imaging control board 10. Furthermore, a configuration can be adopted in which the second control board connector 14 is disposed between the first control board connector 13 and the third and fourth control board connectors 15 and 16. This configuration allows for a greater distance between the differential signal transmission line and the power supply line, thereby improving the quality of the output signals from the imaging elements input to the processor 11.

[0051] Third control board connector 15 and fourth control board connector 16 each include a terminal group to which multiple differential signal transmission lines are connected. Therefore, the wiring becomes dense around each of third control board connector 15 and fourth control board connector 16. Therefore, to facilitate the routing of wiring group 15A and wiring group 16A, it is desirable to increase distance L (see FIGS. 2 and 3) in direction X between third control board connector 15 and fourth control board connector 16.

[0052] For example, routing of wiring group 15A and wiring group 16A can be facilitated by setting distance L to at least one-fourth of the maximum total number of differential signal transmission lines connectable between third control board connector 15 and fourth control board connector 16 multiplied by the width of the differential signal transmission lines. In the above example, the total number of differential signal transmission lines connectable to each of third control board connector 15 and fourth control board connector 16 is eight. Therefore, distance L should be set to at least twice the width of the differential signal transmission lines.

[0053] Alternatively, by setting distance L to at least half the width of the widest width of third control board connector 15 or fourth control board connector 16 in the direction in which the terminals are arranged (direction X), wiring group 15A and wiring group 16A can be easily routed. In the above example, third control board connector 15 and fourth control board connector 16 have the same width. Therefore, distance L may be set to at least half the width of either third control board connector 15 or fourth control board connector 16 in direction X.

[0054] Alternatively, by setting distance L to be equal to or greater than the width of the largest area in direction X among the areas in which the differential signal input terminals of processor 11 connected to third control board connector 15 and fourth control board connector 16 are arranged, wiring group 15A and wiring group 16A can be easily routed. In the above example, the width of the area in which the differential signal input terminals connected to third control board connector 15 are arranged is the same as the width of the area in which the differential signal input terminals connected to fourth control board connector 16 are arranged. Therefore, distance L may be set to be equal to or greater than the width of either of these two areas.

[0055] Up to this point, an example has been described in which the imaging control board 10 is provided with two connectors for connecting differential signal transmission lines, the third control board connector 15 and the fourth control board connector 16. However, three or more connectors for connecting differential signal transmission lines may be provided. Even when three or more connectors are provided, by setting the distance between two adjacent connectors to the same as the above-mentioned distance L, it is possible to simplify the routing of the wiring group and reduce manufacturing costs. It is also possible to accommodate an increase in the number of models of the electronic device 1.

[0056] 4 is a schematic diagram showing an imaging control board 10A that is a first modified example of the imaging control board 10. The imaging control board 10A has the same configuration as the imaging control board 10, except that the third control board connector 15 and the fourth control board connector 16 are integrated into a fifth control board connector 17. The fifth control board connector 17 has 32 terminals arranged in the direction X, and these 32 terminals are connected to 32 differential signal input terminals included in the processor 11 by a wiring group 17A.

[0057] Even with the configuration of the imaging control board 10A, by changing the number of differential signal transmission lines on the FPC board side that are connected to the terminals of the fifth control board connector 17 depending on the model of the electronic device 1, it is possible to accommodate different imaging elements without changing the imaging control board 10A.

[0058] 5 is a schematic diagram showing an imaging control board 10B which is a second modified example of the imaging control board 10. The imaging control board 10B has the same configuration as the imaging control board 10, except that the terminal group 11B is divided into two and the positions of the fourth control board connector 16 and the wiring group 16A are changed.

[0059] One of the two divided terminal groups 11B is formed to extend in direction X along the long side of the rectangular processor 11. The other of the two divided terminal groups 11B is formed to extend in direction Y along the short side of the rectangular processor 11. The fourth control board connector 16 is formed to extend in direction Y along the short side of the processor 11. The extension direction of terminal group 11B is the same as the arrangement direction of the multiple differential signal input terminals included in terminal group 11B. The extension direction of fourth control board connector 16 is the same as the arrangement direction of the multiple terminals included in fourth control board connector 16.

[0060] According to the imaging control board 10B, similarly to the imaging control board 10, the arrangement direction of the multiple terminals included in the third control board connector 15 coincides with the arrangement direction of the differential signal input terminals of the processor 11 connected to those multiple terminals. Furthermore, the arrangement direction of the multiple terminals included in the fourth control board connector 16 coincides with the arrangement direction of the differential signal input terminals of the processor 11 connected to those multiple terminals. Since the arrangement direction of the connector terminals coincides with the arrangement direction of the differential signal input terminals, the wiring lengths of the wiring groups 15A and 16A can be shortened, thereby improving the quality of the differential signals input to the processor 11. Furthermore, the routing of the wiring groups 15A and 16A can be simplified, thereby reducing the manufacturing cost of the imaging control board 10B.

[0061] 6 is a schematic diagram showing an imaging control board 10C which is a third modified example of the imaging control board 10. The imaging control board 10C has almost the same configuration as the imaging control board 10, except that instead of the processor 11, the imaging control board 10C has multiple (two in the example of FIG. 6) processors 11a and 11b.

[0062] Processor 11a is provided with terminal group 11B in which a plurality of differential signal input terminals are arranged in direction X, and terminal group 11B is connected to third control board connector 15 by wiring group 15A. Processor 11a is provided with terminal group 11A in which a plurality of control terminals are arranged in direction Y, and terminal group 11A is connected to second control board connector 14 by wiring group 14A. Processor 11b is provided with terminal group 11B in which a plurality of differential signal input terminals are arranged in direction X, and terminal group 11B is connected to fourth control board connector 16 by wiring group 16A.

[0063] In this way, even when there are multiple processors, the arrangement direction of the terminals of the connector connected to the FPC board and the arrangement direction of the differential signal input terminals are the same, so that the wiring lengths of the wiring groups 15A and 16A can be shortened, thereby improving the quality of the signals input to the processors 11a and 11b.In addition, the routing of the wiring groups 15A and 16A can be simplified, thereby reducing the manufacturing cost of the imaging control board 10C.

[0064] 7 is a schematic diagram showing an imaging control board 10D that is a fourth modified example of the imaging control board 10. The imaging control board 10D differs from the imaging control board 10 in that it has an opening 18H in the region between the edge on one side in direction Y (the lower side in the figure) and the third control board connector 15 and the fourth control board connector 16.

[0065] 7, the plug of the third FPC board F3 is inserted into the opening 18H from the side opposite the main surface 10a of the imaging control board 10D and connected to the third control board connector 15 and the fourth control board connector 16. By configuring the third FPC board F3 to be connected to the third control board connector 15 and the fourth control board connector 16 through the opening 18H in this way, the length of the differential signal transmission lines included in the third FPC board F3 can be shortened, thereby improving the quality of the signals input to the processor 11.

[0066] As shown in FIG. 1, the vibration isolation unit 30 and the imaging control board 10 are connected by an FPC board FS2. For this reason, the imaging control board 10 is provided with an vibration isolation connector (not shown) for connecting to the vibration isolation unit 30. This vibration isolation connector may be divided into multiple parts, and each connector may be connected to the processor 11 by a group of wires.
