[0004] [Patent Document 1] Utility Model Registration No. 3212029 [Patent Document 2] Utility Model Registration No. 3225157 Summary of the Invention [Problem to be solved by the invention]

[0005] Surveillance cameras often come with multiple types of lenses with different horizontal angles of view. Camera settings are generally adjusted manually at the time of shipment or via a network, but there is a risk of accidentally applying settings that are incompatible with the lens.

[0006] The present invention has been made in consideration of the above-mentioned problems, and a main object of the present invention is to provide a monitoring device, a lens identification method, and a program that are capable of identifying lenses with different horizontal angles of view. [Means for solving the problem]

[0007] In order to solve the above problem, a monitoring device according to one aspect of the present invention includes a camera having a first lens or a second lens having a wider horizontal angle of view than the first lens, a side edge portion of a size that is not visible in an image generated by the camera when captured with the first lens but is visible in the image when captured with the second lens, and an identification unit that identifies whether the camera has the first lens or the second lens based on the image generated by the camera. This makes it possible to identify lenses with different horizontal angles of view.

[0008] In the above aspect, The camera may generate an image with a first resolution or a second resolution having a horizontal resolution higher than the first resolution, the side edge portion having a size that will appear in the image when captured using the second lens at the second resolution, and the identification unit may identify whether the camera has the first lens or the second lens based on the image with the second resolution generated by the camera. This makes it possible to identify lenses using the image with the second resolution.

[0009] In the above aspect, the camera may further include a setting unit that applies image quality settings for the first lens when the camera is identified as having the first lens, and applies image quality settings for the second lens when the camera is identified as having the second lens. This makes it possible to apply image quality settings according to the lens.

[0010] In the above aspect, the setting unit may set the image quality setting for the second lens to disable output of images with the second resolution, thereby preventing images that show side edges from being output.

[0011] In the above aspect, the setting unit may set the image quality setting for the second lens to output an image with a third resolution that has the same aspect ratio as the second resolution but a lower resolution than the second resolution by cropping the image with the second resolution generated by the camera. This makes it possible to generate an image with the third resolution in which side edges are not captured by cropping.

[0012] In the above aspect, the setting unit may generate a setting in the image quality setting for the first lens that outputs an image with a third resolution that has the same aspect ratio as the second resolution but a lower resolution than the second resolution by scaling the image with the second resolution generated by the camera. This makes it possible to generate an image with the third resolution by scaling.

[0013] In the above aspect, the setting unit may set, in the image quality setting for the first lens or the second lens, to output an image with a fourth resolution that has the same aspect ratio as the first resolution but a lower resolution than the first resolution by scaling the image with the first resolution generated by the camera. This makes it possible to generate an image with a fourth resolution by scaling.

[0014] In the above aspect, the setting unit may apply image processing parameters for the first lens when the camera is identified as having the first lens, and apply image processing parameters for the second lens when the camera is identified as having the second lens, thereby making it possible to apply image processing parameters according to the lens.

[0015] In the above aspect, the image processing parameter may be a color matrix, which makes it possible to apply a color matrix according to the lens.

[0016] In the above aspect, the image processing parameter may be white balance, which makes it possible to apply white balance according to the lens.

[0017] In the above aspect, the camera may generate an image having a first aspect ratio or a second aspect ratio that is wider than the first aspect ratio, the side edge portion may be sized to appear in the image when captured using the second lens and the second aspect ratio, and the identification unit may identify whether the camera has the first lens or the second lens based on the image having the second aspect ratio generated by the camera. This makes it possible to identify lenses using images having the second aspect ratio.

[0018] Another aspect of the present invention provides a lens identification method that generates an image using a camera having a first lens or a second lens with a wider horizontal angle of view than the first lens, the camera having side edges that are not visible in the image generated by the camera when captured with the first lens but are visible in the image when captured with the second lens, and identifies whether the camera has the first lens or the second lens based on the image generated by the camera. This makes it possible to identify lenses with different horizontal angles of view.

[0019] According to another aspect of the present invention, there is provided a program that causes a computer to acquire an image generated by a camera having a first lens or a second lens having a wider horizontal angle of view than the first lens, the image having side edges that are not visible in the image generated by the camera when captured with the first lens but are visible in the image when captured with the second lens, and to identify whether the camera has the first lens or the second lens based on the image generated by the camera. This makes it possible to identify lenses with different horizontal angles of view. [Effects of the Invention]

[0020] According to the present invention, it is possible to distinguish between lenses with different horizontal angles of view. [Brief explanation of the drawings]

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this specification and the drawings, elements similar to those described above with reference to the previous drawings will be designated by the same reference numerals, and detailed descriptions thereof may be omitted as appropriate.

[0023] 1 and 2 are a perspective view and a front view showing an example of a monitoring device 1. These figures show a first state of the monitoring device 1. The first state is the state before use, in which the solar panel 3 is laid horizontally. The first state is used, for example, during transportation.

[0024] 3 is a perspective view showing an example of the monitoring device 1. This figure shows a second state of the monitoring device 1. The second state is the state during use, in which the solar panel 3 is standing at an angle.

[0025] Fig. 4 is a perspective view showing an example of a window frame portion 5 provided in the camera / communication unit 4. Fig. 5 is an enlarged cross-sectional view of a main portion taken along line AA in Fig. 2. Fig. 6 is a block diagram showing an example of a monitoring device 1.

[0026] In the figure, the X1 direction is the forward direction, and the X2 direction is the backward direction. The Y1 direction is the right direction, and the Y2 direction is the left direction. The Y1 or Y2 direction is also called the lateral direction. The Z1 direction is the upward direction, and the Z2 direction is the downward direction.

[0027] The monitoring device 1 is equipped with a solar panel 3 and a camera / communication unit 4, and is a camera system capable of transmitting still or video images wirelessly (i.e., without requiring an external power source or wired communication connection) for power and communication.

[0028] The camera and communication unit 4 is disposed below the solar panel 3. The camera and communication unit 4 has a rectangular parallelepiped housing 41 made of synthetic resin, and the housing 41 houses the camera 7 (see FIGS. 5 and 6).

[0029] The camera 7 captures an image of the outside through a photographing window 6 provided in the wall of the housing 41. In other words, the camera 7 detects light from the outside that has passed through the photographing window 6. The photographing window 6 is also called a transmission window. A window frame 5 that surrounds the photographing window 6 is provided on the outside of the wall of the housing 41.

[0030] In addition to the camera 7, the housing 41 of the camera / communication unit 4 also contains a battery 11, a control unit 12, and a communication device 13 (see FIG. 6). The battery 11 is charged with power generated by the solar panel 3 and supplies the charged power to the camera 7, the control unit 12, and the communication device 13.

[0031] Control unit 12 is a controller that controls camera 7. Camera 7 and control unit 12 may be a single unit. Control unit 12 transmits image data generated by camera 7 to the outside via wireless communication provided by communication device 13.

[0032] The control unit 12 includes a computer including a CPU, RAM, ROM, nonvolatile memory, an input / output interface, etc. The CPU executes information processing according to a program loaded from the ROM or nonvolatile memory to the RAM.

[0033] 4 and 5, the window frame 5 is provided separately from the housing 41 and attached to the housing 41. The window frame 5 is made of a synthetic resin material. However, the window frame 5 may be integral with the housing 41, or may be made of metal, ceramic, or the like.

[0034] The photographic window 6 is attached to the window frame portion 5. The photographic window 6 is disposed so as to cover the opening 5a formed in the window frame portion 5. However, the photographic window 6 is not limited to this, and may be attached directly to the housing 41.

[0035] The camera 7 has an image sensor 71 and a lens 72. The lens 72 is, for example, a wide-angle lens or an ultra-wide-angle lens. Details of the lens 72 will be described later.

[0036] The window frame 5 has an upper edge 51 located above the photographic window 6, a pair of side edge portions 52 located on both sides of the photographic window 6, and a lower edge portion 53 located below the photographic window 6. The lower edge portion 53 may be omitted.

[0037] The upper edge 51, the side edge 52, and the lower edge 53 are parts that protrude forward from the imaging window 6 and are connected to each other to form a rectangular frame in a front view. The upper edge 51, the side edge 52, and the lower edge 53 surround the imaging window 6 to prevent raindrops from adhering thereto.

[0038] The upper edge 51 covers the entire upper part of the imaging window 6. That is, the left-to-right width of the upper edge 51 is wider than the left-to-right width of the imaging window 6, the left edge of the upper edge 51 is located to the left of the left edge of the imaging window 6, and the right edge of the upper edge 51 is located to the right of the right edge of the imaging window 6.

[0039] The side edge portions 52 cover the entire sides of the imaging window 6. That is, the vertical length of the side edge portions 52 is longer than the vertical length of the imaging window 6, the upper end of the side edge portions 52 is located above the upper end of the imaging window 6, and the lower end of the side edge portions 52 is located below the lower end of the imaging window 6.

[0040] The protruding length of the upper edge 51 is greater than the protruding length of the side edge 52. The protruding length is the length in the front-to-rear direction of the portion that protrudes forward beyond the imaging window 6. An oblique side portion 523 is provided at the upper portion of the side edge 52, extending in the front-upper direction and connected to the side portion 514 of the upper edge 51.

[0041] A window accommodating recess 56 for accommodating the imaging window 6 is formed in the window frame portion 5. The window accommodating recess 56 has an annular bottom surface that surrounds the opening 5a and faces forward.

[0042] The window frame 5 has a cylindrical portion 55 in which an opening 5a is formed. The cylindrical portion 55 extends rearward from the inner edge of the window housing recess 56 and protrudes rearward beyond the other rear surface of the window frame 5.

[0043] The window frame 5 is fixed to the wall of the housing 41 with screws or the like, with the cylindrical portion 55 inserted into the opening of the housing 41. The camera 7 is fixed inside the housing 41, with the lens 72 positioned inside the cylindrical portion 55.

[0044] The image quality settings for the images output by the monitoring device 1 will be described below.

[0045] Typical aspect ratios for images are 4:3 (see Figure 7) and 16:9 (see Figure 8). 16:9 is a wider aspect ratio than 4:3.

[0046] Typical 4:3 resolutions include Quad-VGA (1280 x 960) and VGA (640 x 480). VGA has the same aspect ratio as Quad-VGA but has a lower resolution than Quad-VGA.

[0047] Typical 16:9 resolutions include FHD (1920 x 1080) and HD (1280 x 720). FHD has a higher horizontal resolution than Quad-VGA. HD has the same aspect ratio as FHD but a lower resolution.

[0048] In the following description, Quad-VGA is an example of a first resolution, FHD is an example of a second resolution, HD is an example of a third resolution, and VGA is an example of a fourth resolution. The monitoring device 1 is assumed to output images in FHD, HD, or VGA.

[0049] The lens 72 of the camera 7 of the monitoring device 1 is one of two types of lenses with different horizontal angles of view. In this embodiment, the lens 72 is a wide-angle lens 72A or an ultra-wide-angle lens 72B with an even wider horizontal angle of view (see FIGS. 9 to 12). In the following description, the wide-angle lens 72A is an example of a first lens, and the ultra-wide-angle lens 72B is an example of a second lens.

[0050] For example, as shown in Fig. 9, the horizontal angle of view obtained when wide-angle lens 72A is used in FHD (second resolution R2) is set to α1. As shown in Fig. 10, the horizontal angle of view obtained when ultra-wide-angle lens 72B is used in FHD is set to α2.

[0051] 11, the horizontal angle of view obtained when wide-angle lens 72A is used with Quad-VGA (first resolution R1) is denoted by β1. As shown in FIG. 12, the horizontal angle of view obtained when ultra-wide-angle lens 72B is used with Quad-VGA is denoted by β2.

[0052] Quad-VGA has a lower horizontal resolution than FHD, i.e., occupies a narrower width on the image sensor 71, so that the horizontal angle of view β1 is smaller than the horizontal angle of view α1, and the horizontal angle of view β2 is smaller than the horizontal angle of view α2.

[0053] When the horizontal angle of view α1 obtained when using wide-angle lens 72A in FHD satisfies the required specifications (for example, 90 degrees or more), the horizontal angle of view β1 obtained when using wide-angle lens 72A in Quad-VGA may not satisfy the required specifications.

[0054] Furthermore, if the horizontal angle of view β2 obtained when using the ultra-wide-angle lens 72B in Quad-VGA satisfies the required specifications, the horizontal angle of view α2 obtained when using the ultra-wide-angle lens 72B in FHD may become too large, resulting in distortion.

[0055] As such, it is preferable to apply FHD when wide-angle lens 72A is used, and it is preferable to apply Quad-VGA when ultra-wide-angle lens 72B is used, but with the conventional method of manually switching a switch or the like, there is a risk of accidentally applying an image quality setting that does not match the type of lens 72.

[0056] Therefore, in this embodiment, as shown in Figures 9 to 12, the side edge portion 52 of the window frame portion 5 is sized so that it appears in the FHD image captured by the ultra-wide-angle lens 72B (see Figure 10) but does not appear in other cases, thereby automatically identifying whether the camera 7 has a wide-angle lens 72A or an ultra-wide-angle lens 72B.

[0057] The side edge 52 of the window frame portion 5 does not appear in the FHD image captured by the wide-angle lens 72A (see Figure 9), does not appear in the Quad-VGA image captured by the wide-angle lens 72A (see Figure 11), and does not appear in the Quad-VGA image captured by the ultra-wide-angle lens 72B (see Figure 12).

[0058] 13 is a block diagram showing an example of the configuration of the control unit 12. The control unit 12 includes an acquisition unit 15, a recognition unit 16, and a setting unit 17. These functional units are realized by the CPU of the control unit 12 executing information processing in accordance with a program.

[0059] 14 is a flow diagram showing an example of a lens identification method implemented in the monitoring device 1. The control unit 12 executes the information processing shown in the diagram in accordance with a program. The information processing shown in the diagram is executed, for example, at the time of shipment.

[0060] Fig. 15 is a diagram showing an example of an FHD image captured by the ultra-wide-angle lens 72B. Side edges 52 are visible on both sides of this image. Fig. 16 is a diagram showing examples of image quality settings for the ultra-wide-angle lens and the wide-angle lens.

[0061] First, the control unit 12 acquires an FHD image generated by the camera 7 (S11, processing as the acquisition unit 15).

[0062] Next, the control unit 12 identifies whether the camera 7 has the super-wide-angle lens 72B or the wide-angle lens 72A, based on the FHD image generated by the camera 7 (S12, processing as the identification unit 16).

[0063] Whether it is the ultra-wide-angle lens 72B or the wide-angle lens 72A is determined by whether the side edges 52 are visible on both sides of the FHD image, more specifically, whether there are dark areas of a predetermined width on both sides.

[0064] If the side edges 52 are visible on both sides of the FHD image, the camera is identified as having an ultra-wide-angle lens 72B, and if the side edges 52 are not visible on both sides of the FHD image, the camera is identified as having a wide-angle lens 72A.

[0065] If it is identified that the camera 7 has an ultra-wide-angle lens 72B (S13: ultra-wide-angle lens), the control unit 12 applies image quality settings for the ultra-wide-angle lens (S14, processing as the setting unit 17, see Figure 16).

[0066] Specifically, the control unit 12 disables the output of FHD images in the image quality setting for the super wide-angle lens, because the side edge 52 is visible in the image (see FIGS. 10 and 15).

[0067] Furthermore, for the FHD output in the image quality setting for the ultra-wide-angle lens, the control unit 12 sets the setting to output an HD image by cropping the FHD image generated by the camera 7. This is because scaling the image would result in the side edge 52 appearing in the image (see FIGS. 10 and 15).

[0068] Furthermore, for HD output in the image quality setting for the ultra-wide-angle lens, the control unit 12 sets the setting to output a VGA image by scaling the Quad-VGA image generated by the camera 7. This is because a larger horizontal angle of view can be secured than with cropping (see FIG. 12).

[0069] Furthermore, the control unit 12 may apply image processing parameters (color matrix, white balance, etc.) for the super wide-angle lens that are created in advance to suit the super wide-angle lens 72B to the VGA output in the super wide-angle lens image quality setting.

[0070] On the other hand, if it is identified that the camera 7 has a wide-angle lens 72A (S13: wide-angle lens), the control unit 12 applies the image quality setting for the wide-angle lens (S15, processing as the setting unit 17, see FIG. 16).

[0071] Specifically, the control unit 12 sets the FHD output in the wide-angle lens image quality setting to output the FHD image generated by the camera 7 as is.

[0072] Furthermore, for HD output in the wide-angle lens image quality setting, the control unit 12 sets the setting to output an HD image by scaling the FHD image generated by the camera 7. This is because a larger horizontal angle of view can be secured than with cropping (see FIG. 9).

[0073] Furthermore, for VGA output in the wide-angle lens image quality setting, the control unit 12 sets the setting to output a VGA image by scaling the Quad-VGA image generated by the camera 7. In this case, since there is a risk that a sufficient horizontal angle of view cannot be guaranteed (see FIG. 11), a notification to that effect may be provided.

[0074] Furthermore, in the wide-angle lens image quality setting, the control unit 12 may apply image processing parameters (color matrix, white balance, etc.) that have been adjusted in advance for the wide-angle lens 72A.

[0075] According to the embodiment described above, it is possible to automatically identify the lens 72A or 72B of the camera 7, and further, it is possible to automatically apply image quality settings according to the identified lens 72A or 72B.
