[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0050] It will be understood that when used in this specification and the appended claims, the terms “comprises” and “comprising” indicate the presence of described features, integers, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0051] It should also be understood that the terms used in the present specification are only for the purpose of describing particular embodiments and are not intended to limit the present invention. As used in the present specification and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0052] It should be further understood that the term "and / or" used in the present description and appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0053] An embodiment of the present invention provides a joint testing method for a surveillance camera's photosensitive device, fill light, and IR-Cut device. Before testing, a testing device needs to be set up. Specifically, a black box is prepared. There is a standard light source inside the black box. The standard light source can generate light of different standard brightness depending on the connection to the light controller. A bracket is provided at a position opposite to the black box. The bracket has a hole for placing the camera under test. The camera under test and the light controller are both connected to a controller computer. A background infrared fill light is also installed on the bracket.

[0054] like Figure 1 As shown, a joint testing method for a photosensor, a fill light, and an IR-Cut device of a surveillance camera includes the following steps: S10-S30.

[0055] S10. Adjust the brightness of the standard light source to a first brightness, a second brightness, and a third brightness in sequence, wherein the light intensity of the second brightness is greater than the first brightness and less than the light intensity of the third brightness, and the first brightness is the light intensity of the fill light of the corresponding camera under test from the off state to the on state, and the third brightness is the light intensity of the fill light of the corresponding camera under test from the on state to the off state.

[0056] After booting up the computer, powering up the black box lighting controller and light source, the camera under test is placed in the hole opposite the black box and connected to the computer's network. Once the connection is established, the computer first sends a command to the lighting controller to adjust the standard light source's brightness to the first, second, and third levels. The three different brightness levels are required to prevent photosensitive device failures and ensure more stable calibration.

[0057] In this embodiment, the first brightness is a brightness that roughly meets the standard of nighttime light intensity, the third brightness is a brightness that roughly meets the standard of daytime light intensity, and the second brightness is between the first and third brightnesses.

[0058] It should be noted that due to the different photosensitivity parameters of different cameras, for example, when the external light intensity is A, some cameras believe that it is time to turn on the fill light, while when the external light intensity is A, other cameras believe that it is not time to turn on the fill light. Therefore, the first brightness, the third brightness and the light intensity need to be determined in combination with the photosensitivity parameters of the camera being tested.

[0059] S20. Sequentially obtain a first light sensitivity value, a second light sensitivity value, and a third light sensitivity value read by the camera under test at a first brightness, a second brightness, and a third brightness, respectively.

[0060] The computer sends instructions to the camera under test, and the photosensor of the camera under test reads the photosensitivity value under different brightness.

[0061] In this embodiment, the first photosensitivity value is read at a first brightness, the second photosensitivity value is read at a second brightness, and the third photosensitivity value is read at a third brightness.

[0062] S30. If the second photosensitivity value is greater than the first photosensitivity value and less than the third photosensitivity value, the first photosensitivity value is used as the first switching threshold for the camera under test to switch from the first mode to the second mode, and the third photosensitivity value is used as the second switching threshold for the camera under test to switch from the second mode to the first mode.

[0063] The computer program will determine the relationship between the read first, second and third photosensitivity values. If the second photosensitivity value is greater than the first photosensitivity value and less than the third photosensitivity value, the computer program will use the first photosensitivity value as the first switching threshold for the camera under test to switch from the first mode to the second mode, and the third photosensitivity value as the second switching threshold for the camera under test to switch from the second mode to the first mode. At this point, the calibration of the photosensitive device is completed.

[0064] In this embodiment, the first mode is the day mode of the camera under test, and the second mode is the night mode of the camera under test; when the camera under test reads that the photosensor value is lower than the first switching threshold, the camera under test will switch from the first mode to the second mode; when the camera under test reads that the photosensor value is higher than the second switching threshold, the camera under test will switch from the second mode to the first mode, thereby realizing the mode switching of the camera under test according to the photosensitivity value, providing a basis for subsequent IR-Cut device and fill light detection.

[0065] In one embodiment, if Figure 2As shown, a joint testing method for a photosensor, a fill light, and an IR-Cut device of a surveillance camera further includes the following steps: S40-S70.

[0066] S40: Turn on the background infrared fill light, turn on the filter function of the IR-Cut device of the camera under test, and obtain the image captured by the camera under test.

[0067] S50: If it is determined that the captured image is not overexposed, it is determined that the light filtering function of the R-Cut device is normal.

[0068] The captured image can be analyzed to determine whether it is overblown. If it is not overblown, the IR-Cut device's filtering function is effective, and therefore the IR-Cut device's filtering function can be determined to be normal. It should be noted that analyzing captured images for overblown conditions is a conventional technique in the art, and the detailed analysis process will not be detailed here.

[0069] S60: Turn off the switch of the IR-Cut device of the camera under test, and obtain the image captured by the camera under test.

[0070] S70: If the captured image is analyzed to be overexposed, it is determined that the switch function of the IR-Cut device is normal.

[0071] If the captured image appears over-exposure after the IR-Cut device is turned off, it means that the switch function of the IR-Cut device is normal.

[0072] By analyzing the overexposure of the image, it is possible to determine not only whether the filtering function of the IR-Cut device is normal, but also whether the switching function of the IR-Cut device is normal.

[0073] In one embodiment, if Figure 3 As shown, a joint testing method for a photosensor, a fill light, and an IR-Cut device of a surveillance camera further includes the following steps: S80-S130.

[0074] S80. Turn off the background infrared fill light and monitor the photosensor of the camera under test.

[0075] S90: Determine whether the current light intensity sensed by the photosensor is lower than a first photosensitivity value.

[0076] S100: If the current light intensity is lower than the first photosensitivity value, check whether the switch of the fill light of the camera under test is automatically turned on.

[0077] S110: If the switch of the fill light is automatically turned on, it is determined that the switch function of the fill light of the camera under test is normal.

[0078] S120: Determine whether the fill light of the camera under test is started normally.

[0079] S130: If the system can be started normally, it is determined that the fill light function of the fill light of the camera under test is normal.

[0080] In this embodiment, if the current light intensity is lower than the first photosensitivity value, it indicates that the camera under test needs to enter night mode (i.e., the second mode). In night mode, the background infrared fill light needs to be turned on and the IR-Cut device needs to be turned off. It should be noted that the background infrared fill light and the fill light of the camera under test are different components.

[0081] By checking whether the switch of the fill light of the tested camera is automatically turned on, it is determined whether the switch function of the fill light of the tested camera is normal. If the switch is automatically turned on, it means that the switch function of the fill light of the tested camera is normal, otherwise it is abnormal.

[0082] Next, after determining whether the switch function of the fill light of the tested camera is normal, determine whether the fill light is started normally. If it can be started normally, it is determined that the fill light function of the fill light of the tested camera is normal, otherwise it is abnormal.

[0083] The present invention can not only calibrate the photosensitive device, but also complete the test of the IR-Cut device and the fill light after the calibration is completed, thereby realizing joint testing, making the test faster and more stable, and improving the test efficiency.

[0084] Figure 4 A schematic block diagram of a device for jointly testing a photosensitive device, a fill light, and an IR-Cut device of a surveillance camera provided in an embodiment of the present invention; corresponding to the above-mentioned method for jointly testing a photosensitive device, a fill light, and an IR-Cut device of a surveillance camera, an embodiment of the present invention further provides a device 100 for jointly testing a photosensitive device, a fill light, and an IR-Cut device of a surveillance camera.

[0085] like Figure 4 As shown, a joint testing device 100 for a photosensor, a fill light, and an IR-Cut device of a surveillance camera includes an adjusting unit 110 , an acquiring unit 120 , and a switching unit 130 .

[0086] The adjustment unit 110 is used to adjust the brightness of the standard light source to a first brightness, a second brightness, and a third brightness in sequence, wherein the light intensity of the second brightness is greater than the first brightness and less than the light intensity of the third brightness, and the first brightness is the light intensity of the fill light of the corresponding camera under test from the off state to the on state, and the third brightness is the light intensity of the fill light of the corresponding camera under test from the on state to the off state.

[0087] After booting up the computer, powering up the black box lighting controller and light source, the camera under test is placed in the hole opposite the black box and connected to the computer's network. Once the connection is established, the computer first sends a command to the lighting controller to adjust the standard light source's brightness to the first, second, and third levels. The three different brightness levels are required to prevent photosensitive device failures and ensure more stable calibration.

[0088] In this embodiment, the first brightness is a brightness that roughly meets the standard of nighttime light intensity, the third brightness is a brightness that roughly meets the standard of daytime light intensity, and the second brightness is between the first and third brightnesses.

[0089] It should be noted that due to the different photosensitivity parameters of different cameras, for example, when the external light intensity is A, some cameras believe that it is time to turn on the fill light, while when the external light intensity is A, other cameras believe that it is not time to turn on the fill light. Therefore, the first brightness, the third brightness and the light intensity need to be determined in combination with the photosensitivity parameters of the camera being tested.

[0090] The acquisition unit 120 is used to sequentially acquire a first light sensitivity value, a second light sensitivity value, and a third light sensitivity value read by the camera under test at a first brightness, a second brightness, and a third brightness, respectively.

[0091] The computer sends instructions to the camera under test, and the photosensor of the camera under test reads the photosensitivity value under different brightness.

[0092] In this embodiment, the first photosensitivity value is read at a first brightness, the second photosensitivity value is read at a second brightness, and the third photosensitivity value is read at a third brightness.

[0093] The switching unit 130 is used to use the first light sensitivity value as the first switching threshold for the camera under test to switch from the first mode to the second mode if the second light sensitivity value is greater than the first light sensitivity value and less than the third light sensitivity value, and use the third light sensitivity value as the second switching threshold for the camera under test to switch from the second mode to the first mode.

[0094] The computer program will determine the relationship between the read first, second and third photosensitivity values. If the second photosensitivity value is greater than the first photosensitivity value and less than the third photosensitivity value, the computer program will use the first photosensitivity value as the first switching threshold for the camera under test to switch from the first mode to the second mode, and the third photosensitivity value as the second switching threshold for the camera under test to switch from the second mode to the first mode. At this point, the calibration of the photosensitive device is completed.

[0095] In this embodiment, the first mode is the day mode of the camera under test, and the second mode is the night mode of the camera under test; when the camera under test reads that the photosensor value is lower than the first switching threshold, the camera under test will switch from the first mode to the second mode; when the camera under test reads that the photosensor value is higher than the second switching threshold, the camera under test will switch from the second mode to the first mode, thereby realizing the mode switching of the camera under test according to the photosensitivity value, providing a basis for subsequent IR-Cut device and fill light detection.

[0096] In one embodiment, if Figure 5 As shown, the joint testing device 100 for the photosensor, fill light and IR-Cut device of a surveillance camera further includes an opening unit 140 , a first determination unit 150 , a closing unit 160 and a second determination unit 170 .

[0097] The activation unit 140 is used to activate the background infrared fill light, activate the light filtering function of the IR-Cut device of the camera under test, and obtain the image captured by the camera under test.

[0098] The first determination unit 150 is configured to determine that the light filtering function of the IR-Cut device is normal if the captured image is analyzed to be not overexposed.

[0099] The captured image can be analyzed to determine whether it is overblown. If it is not overblown, the IR-Cut device's filtering function is effective, and therefore the IR-Cut device's filtering function can be determined to be normal. It should be noted that analyzing captured images for overblown conditions is a conventional technique in the art, and the detailed analysis process will not be detailed here.

[0100] The closing unit 160 is used to turn off the switch of the IR-Cut device of the camera under test and obtain the image captured by the camera under test.

[0101] The second determination unit 170 is configured to determine whether the switch function of the IR-Cut device is normal if the captured image is found to be overexposed.

[0102] If the captured image appears over-exposure after the IR-Cut device is turned off, it means that the switch function of the IR-Cut device is normal.

[0103] By analyzing the overexposure of the image, it is possible to determine not only whether the filtering function of the IR-Cut device is normal, but also whether the switching function of the IR-Cut device is normal.

[0104] In one embodiment, if Figure 6As shown, the joint testing device 100 for the photosensor, fill light and IR-Cut device of the surveillance camera further includes a monitoring unit 180, a first judgment unit 190, an inspection unit 200, a third judgment unit 210, a second judgment unit and a fourth judgment unit;

[0105] The closing unit 180 is used to turn off the background infrared fill light and monitor the photosensor of the camera under test.

[0106] The first judging unit 190 is configured to judge whether the current light intensity sensed by the photosensor is lower than a first photosensitivity value.

[0107] The checking unit 200 is configured to check whether the switch of the fill light of the camera under test is automatically turned on if the current light intensity is lower than the first photosensitivity value.

[0108] The third determination unit 210 is configured to determine whether the switch function of the fill light of the camera under test is normal if the fill light switch is automatically turned on;

[0109] The second judging unit 220 is used to judge whether the fill light of the camera under test is started normally.

[0110] The fourth determination unit 230 is configured to determine whether the fill light function of the fill light of the camera under test is normal if the fill light can be started normally.

[0111] In this embodiment, if the current light intensity is lower than the first photosensitivity value, it indicates that the camera under test needs to enter night mode (i.e., the second mode). In night mode, the background infrared fill light needs to be turned on and the IR-Cut device needs to be turned off. It should be noted that the background infrared fill light and the fill light of the camera under test are different components.

[0112] By checking whether the switch of the fill light of the tested camera is automatically turned on, it is determined whether the switch function of the fill light of the tested camera is normal. If the switch is automatically turned on, it means that the switch function of the fill light of the tested camera is normal, otherwise it is abnormal.

[0113] Next, after determining whether the switch function of the fill light of the tested camera is normal, determine whether the fill light is started normally. If it can be started normally, it is determined that the fill light function of the fill light of the tested camera is normal, otherwise it is abnormal.

[0114] The combined testing device for the above-mentioned monitoring camera's photosensor, fill light and IR-Cut device can be implemented in the form of a computer program. The computer program can be used in a computer system such as Figure 7 Runs on the computer equipment shown.
