  By the way, in the vehicular visual recognition device that displays captured images around the vehicle, the visual recognition range may be changed by changing the cutout range of the captured image, moving the imaging direction, or the like. In this way, when irradiating infrared rays around the vehicle when changing the visible range, it is necessary to irradiate infrared light over a wide range that covers the changeable range of the visible range, but in order to reduce power consumption It is not preferable to irradiate a wider area than necessary.

  In patent document 1, although the irradiation intensity of infrared rays is changed by changing the lighting number of near-infrared LED according to a target distance, it is the point which suppresses irradiation of the infrared light to an unnecessary area | region.

The display unit is controlled to display the image as a work image. Thereby, the periphery of the vehicle can be confirmed by the visual image even in a dark area such as at night. In addition, since infrared light is irradiated to the area around the vehicle corresponding to at least a part of the partial image, it is necessary to suppress the irradiation of infrared light to unnecessary areas and visually recognize the vicinity of the vehicle. The region can be irradiated with infrared light.

  Note that, as in the invention described in claim 2, the control unit may control the irradiating unit so as to irradiate infrared light to an area around the vehicle corresponding to the entire partial image. Thereby, it becomes possible to illuminate the area | region of the vehicle periphery corresponding to the whole image for visual recognition with infrared light.

  Further, as in the third aspect of the invention, the irradiating unit includes a plurality of infrared light sources that respectively irradiate a region around the vehicle corresponding to each divided region obtained by dividing the captured image into a plurality of regions, and the control unit includes a part The irradiation unit may be controlled to turn on an infrared light source that irradiates an area around the vehicle corresponding to a divided area overlapping at least a part of the image. Accordingly, it is possible to irradiate a necessary region with infrared light, and it is possible to reduce power consumption without turning on the infrared light source unnecessarily.

  Further, as in the invention described in claim 4, the irradiating unit includes an infrared light source that irradiates infrared light and a changing unit that changes an irradiation direction of the infrared light irradiated from the infrared light source. The irradiation unit may be controlled so that the irradiation direction is changed by the changing unit and the region around the vehicle corresponding to at least a part of the partial image is irradiated with infrared light. This makes it possible to irradiate the necessary area with infrared light.

The control device 18 changes the viewing range on the rear side of the vehicle when reversing to make it easier to visually recognize obstacles on the lower side of the vehicle, and sets the viewing range in conjunction with the operation of the direction indicator. You may make it change and carry out turning interlocking control etc. which make it easy to visually recognize the vehicle rear side.

  Then, the structure of the control system of the visual recognition apparatus 10 for vehicles which concerns on this embodiment is demonstrated. FIG. 2 is a block diagram illustrating a configuration of a control system of the vehicle visual recognition device 10 according to the present embodiment.

  The control device 18 includes a microcomputer in which a CPU 18A, a ROM 18B, a RAM 18C, and an I / O (input / output interface) 18D are connected to a bus 18E.

  The ROM 18B stores various programs such as a visual image display control program for performing display control for displaying the captured image 30 on the rear side of the rear side camera 12 on the monitor 14, and a near infrared illumination lighting control program. Has been. The program stored in the ROM 18B is expanded in the RAM 18C and executed by the CPU 18A, whereby display control on the monitor 14 is performed.

  The I / O 18D is connected with an operation unit 16, a rear side camera 12, a monitor 14, and a near-infrared illumination 20 for instructing a change in the viewing range.

  The operation unit 16 outputs a change instruction signal to the control device 18 when an instruction to change the rear side viewing range is given by the occupant. Specifically, the operation unit 16 includes the above-described left switch 16L, right switch 16R, and direction instruction unit 16S illustrated in FIG. That is, the direction (left or right) corresponding to the monitor 14 whose viewing range is changed is instructed by the left switch 16L or the right switch 16R, and the viewing direction changing direction (vehicle width direction and vehicle up-down direction) is directed by the direction instruction unit 16S. Instruct.

  The rear side camera 12 obtains a rear side photographed image 30 by photographing the rear side of the vehicle. The rear side photographed image 30 obtained by photographing is output to the control device 18 as a photographing result of the rear side camera 12.

  The monitor 14 displays the rear side captured image 30 captured by the rear side camera 12 in accordance with the control of the control device 18.

  The near-infrared illumination 20 irradiates infrared light to a necessary region in the imaging region of the rear side camera 12 by controlling the lighting of the plurality of infrared LEDs 22 by the control device 18.

  Then, the control device 18 performs display control on the monitor 14 based on the photographing result of the rear side camera 12, and when the operation unit 16 instructs the change of the rear side viewing range, the monitor 14 The display position (rear side viewing range) is changed.

  Although not shown in the figure, the control device 18 is connected to various control devices such as an engine ECU and an air conditioner ECU so that vehicle information can be acquired. Signals such as light switches and illuminance sensors are detected. When the surroundings are dark, such as at night, the lighting of the near-infrared illumination 20 is controlled.

  In addition, the control apparatus 18 may perform display control of the left and right monitors 14 with one control apparatus 18, or a pair may be provided corresponding to the left and right of the vehicle. When a pair of control devices 18 are provided corresponding to the left and right, the other control device 18 may be connected to each I / O 18D so that they can communicate with each other.

  Here, the display method of the captured image 30 of the rear side camera 12 on the monitor 14 by the control device 18 will be described in detail. FIG. 4 is a diagram for explaining a visual image generated from the captured image 30.

  In the vehicular visual recognition device 10 according to the present embodiment, as shown in FIG. 4, the rear side camera 12 captures the rear side of the vehicle, and a partial image indicated by a dotted line in FIG. 4 from a captured image 30 obtained by the imaging. Cut out 32. Then, the cut out partial image 32 is displayed on the monitor 14 as a visual image 34. That is, in the vehicular visual recognition device 10 according to the present embodiment, since the partial image 32 in a partial range of the captured image 30 is displayed, the visual recognition range can be changed by changing the cutout position. The viewing range is changed by operating the operation unit 16. Specifically, the direction (left or right) for changing the viewing range is selected by operating the left switch 16L or the right switch 16R, and the direction indicating unit 16S is operated to change the viewing range changing direction (vehicle width direction and In the vehicle vertical direction). Accordingly, the control device 18 changes the position of the partial image 32 cut out in the direction operated by the operation unit 16 from the current position of the partial image 32 of the captured image 30 and displays the visual image 34 on the monitor 14. That is, the visual image 34 displayed on the monitor 14 is sequentially moved and displayed in the direction indicated by the direction instruction unit 16S.

  Note that the visual image 34 is subjected to mirror image conversion in order to display the same image as the optical mirror on the monitor 14, and therefore the captured image 30 in FIG. 4 includes a partial image 32 and a visual image 34 in the captured image 30. In order to make the relationship easy to understand, it is shown as a mirror image-converted image.

  In addition, the change of the viewing range is not limited to the case where it is instructed by the operation unit 16, for example, the backward interlock control for changing the viewing range in conjunction with the above-described backward movement, or the viewing range is changed in conjunction with the turning. The predetermined condition for performing the turning interlocking control to be performed may be satisfied. Here, the predetermined conditions for performing the reverse interlocking control and the turning interlocking control are predetermined conditions based on, for example, a direction indicator, a shift position, a vehicle speed, and the like, and well-known conditions can be applied.

  By the way, as described above, the near-infrared illumination 20 divides the captured image 30 into 15 regions and includes the infrared LEDs 22 corresponding to the respective divided regions. Irradiation of infrared light to unnecessary areas can be suppressed by irradiating light.

  Therefore, in the present embodiment, the control device 18 extracts a divided region that overlaps the partial image 32 from among the divided regions obtained by dividing the captured image 30 into 15. And the near-infrared illumination 20 is controlled so that the infrared LED 22 corresponding to the extracted divided area is turned on.

  For example, as shown in FIG. When overlapping with the divided areas of 1, 2, 3, 6, 7, and 8, as shown in FIG. 1, 2, 3, 6, 7, and 8 are turned on. Thereby, it is possible to irradiate infrared light to a necessary region while suppressing irradiation of infrared light to an unnecessary region. Moreover, what is necessary is just to change infrared LED22 which lights together with the change of a visual recognition range, when changing a visual recognition range.

  Then, the specific process performed with the control apparatus 18 of the visual device 10 for vehicles which concerns on this embodiment comprised as mentioned above is demonstrated.

  First, display control of the visual image 34 will be described. FIG. 6 is a flowchart illustrating an example of a flow of processing relating to display control of the visual image 34 performed by the control device 18 of the vehicle visual device 10 according to the present embodiment. The process in FIG. 6 will be described as starting when an ignition switch (not shown) is turned on. 6 is performed when the CPU 18A develops and executes the visual image display control program stored in the ROM 18B on the RAM 18C.

  First, in step 100, the CPU 18 </ b> A starts acquiring the captured image 30 captured by the rear side camera 12 and proceeds to step 102. That is, the imaging results of the rear side camera 12 are sequentially acquired.

  In step 102, the CPU 18 </ b> A cuts out the partial image 32 from the captured image 30 and proceeds to step 104. Note that the partial image 32 at this time may be a partial image 32 at a predetermined default position in the captured image 30 or may be a partial image 32 at the position instructed last time before the ignition switch is turned off.

  In step 104, the CPU 18A performs mirror image conversion on the cut out partial image 32, and displays it on the monitor 14 as a visual image 34, as shown in FIG. Instead of performing the mirror image conversion on the partial image 32, the partial image 32 may be cut out after the captured image 30 is converted into a mirror image.

  In step 106, the CPU 18A determines whether or not the viewing range is changed. In this determination, for example, it is determined whether or not the operation unit 16 has been operated to instruct a change in the viewing range. If the determination is affirmative, the process proceeds to step 108. If the determination is negative, the process ends and other processing such as processing related to lighting control of near-infrared illumination described later is performed. Note that, instead of whether or not the change of the viewing range is instructed by the operation unit 16, it may be determined whether or not a predetermined condition for performing the reverse interlocking control or the turning interlocking control is satisfied. Or at least one of the instruction to change the visual range by the operation unit 16 and the instruction to change the visual range when a predetermined condition for performing interlocking control (at least one of reverse interlocking control and turning interlocking control) is performed. It may be determined whether or not.

  In step 108, the CPU 18 </ b> A controls the monitor 14 to change the position where the partial image 32 is cut out according to the instruction and display the visual image 34, and proceeds to step 110.

  In step 110, the CPU 18A performs control so that the partial image 32 changed in accordance with the instruction is converted into a mirror image and displayed on the monitor 14 as a visual image 34, and the process is terminated. Other processing such as processing is performed.

  By controlling in this way, it is possible to display an image for visually recognizing the rear side of the vehicle on the monitor 14 and to confirm the periphery of the vehicle as with the optical mirror.

  Next, lighting control of the near-infrared illumination 20 will be described. FIG. 7 is a flowchart illustrating an example of a flow of processing related to lighting control of near-infrared illumination performed by the control device of the vehicle visual recognition device according to the present embodiment. Note that the processing in FIG. 7 is performed following the processing related to the control of the visual image 34 described above. 7 is performed by the CPU 18A developing and executing the near infrared illumination lighting control program stored in the ROM 18B on the RAM 18C.

  In step 200, the CPU 18 </ b> A acquires vehicle information and position information of the partial image 32, and proceeds to step 202. In the present embodiment, information such as a light switch and an illuminance sensor is acquired as vehicle information as information for determining whether or not the surroundings of the vehicle are dark, and the position of the cut out partial image 32 in the captured image 30 Information is acquired by the CPU 18A.

  In step 202, the CPU 18A determines whether or not the near infrared illumination 20 is turned on. The determination is based on the acquired vehicle information to determine whether the vehicle periphery is dark and it is necessary to turn on near-infrared illumination. Specifically, when acquiring light switch information as vehicle information, it is determined whether or not the light switch is on. When acquiring illuminance sensor information, the illuminance detected by the illuminance sensor Is less than or equal to a predetermined value. If the determination is negative, the process proceeds to step 204. If the determination is affirmative, the process proceeds to step 208.

  In step 204, the CPU 18A determines whether or not the near-infrared illumination 20 has been turned on by a process described later. If the determination is affirmative, the process proceeds to step 206. If the determination is negative, the process ends and the above-described processing related to display control of the visual image 34 is performed.

  In step 206, the CPU 18A controls to turn off the near-infrared illumination 20, terminates the processing, and performs processing related to display control of the visual image 34 described above.

  On the other hand, in step 208, the CPU 18A determines the infrared LED 22 No. I = 1 and the process proceeds to step 210.

  In step 210, the CPU 18 </ b> A determines based on the position information of the partial image 32 whether or not the infrared LED 22 corresponds to the divided area overlapping in the partial image 32. If the determination is negative, the process proceeds to step 212, and if the determination is affirmative, the process proceeds to step 214.

  In step 212, CPU 18A determines No. Control is performed to turn off the infrared LED 22 of i, and the process proceeds to step 216.

  In Step 214, the CPU 18A determines No. Control is performed to turn on the infrared LED 22 of i, and the process proceeds to step 216.

  In step 216, the CPU 18A determines the infrared LED 22 No. Determines whether i> 15. If the determination is negative, the process proceeds to step 218. If the determination is affirmative, the process ends, and the above-described processing related to display control of the visual image 34 is performed.

  In step 218, the CPU 18A determines the infrared LED 22 No. I = i + 1, the process returns to step 210 and the above-described processing is repeated. That is, it is determined whether or not each of the plurality of infrared LEDs 22 is the infrared LED 22 corresponding to the divided region overlapping the partial image 32, and the infrared LED 22 that irradiates the region corresponding to the partial image 32 is controlled to be turned on. To do.

  By performing the processing in this manner, the infrared LED 22 that irradiates the region corresponding to the partial image 32 displayed as the visual image 34 is turned on and the others are turned off, so only the region that needs to be irradiated with infrared light. Can be irradiated with infrared light. In addition, since only the infrared LED 22 that irradiates a necessary area is turned on, power consumption can be reduced compared to the case where the all infrared LED 22 is turned on.

  Even if the viewing range is changed, the lighting of each infrared LED 22 of the near-infrared illumination 20 is controlled corresponding to the changed partial image 32, so that infrared light is irradiated to unnecessary areas. Can be suppressed.

  In the above embodiment, an example has been described in which a plurality of infrared LEDs 22 are provided as the near-infrared illumination 20 and lighting of each infrared LED 22 is controlled to change the region irradiated with infrared light. It is not limited to. For example, as shown in FIG. 8, an infrared light source 40 that outputs infrared light, and a change unit 42 that reflects the light output from the infrared light source 40 and changes the irradiation direction (irradiation region) of the infrared light. A configuration including a lens 44 for irradiating a region corresponding to the partial image 32 with infrared light may be applied. In this case, the changing unit 42 may be a mirror whose angle can be changed and simply changing the irradiation direction, but a mirror device capable of changing the irradiation pattern may be applied. As an example, devices such as Lcos (Liquid Crystal On Silicon), MEMS (Micro Electro Mechanical Systems) mirror, DMD (Digital Micromirror Device) can be applied. Moreover, the lens 44 of FIG. 8 may be omitted and only the infrared light source 40 and the changing unit 42 may be configured.

  In the above-described embodiment, control is performed so that infrared light is applied to a region around the vehicle corresponding to the entire partial image 32. However, the region may not be the region corresponding to the entire partial image 32. An area around the vehicle corresponding to a part of the image 32 may be used. For example, in the example of FIG. 5, since the divided regions 1 to 3 are above the horizon, the necessity of illumination is low, and thus the infrared LED 22 No. 6 to 8 may be turned on and only the regions corresponding to the divided regions 6, 7, and 8 may be irradiated with infrared light.

  In the above-described embodiment, the vehicular visual recognition device that captures and visually recognizes the rear side of the vehicle as a vehicle periphery has been described as an example. However, the present invention is not limited to this. For example, you may apply the visual device for vehicles which image | photographs and displays other directions, such as a vehicle side and the front, back.

  Moreover, although the process performed by the control apparatus 18 in said embodiment was demonstrated as a software process, it is not restricted to this. For example, the processing may be performed by hardware, or may be processing that combines both hardware and software.

  Further, the processing performed by the control device 18 in the above embodiment may be stored and distributed as a program in a storage medium.

  Furthermore, the present invention is not limited to the above, and it goes without saying that various modifications can be made without departing from the spirit of the present invention.
