[0002] Image acquisition equipment (such as camera systems) generally includes a fill light system, which is used to emit light of a certain wavelength to fill in the scene within the camera's field of view. The camera uses the reflected light from the scene under the fill light to form an image.

[0003] Related technologies control the movement of one or more zoom elements to change the focal length of the fill light system, thereby achieving fill light requirements for different field of view angles. Therefore, this fill light method introduces a zoom element and requires sufficient space for its movement, resulting in a larger image acquisition device. Summary of the Invention

[0053] refer to Figure 1, is a system architecture diagram applicable to an embodiment of the present application, which is applied to an image acquisition device, and the image acquisition device includes at least an image acquisition system 101 and a fill light system 102. The image acquisition system 101 is used to acquire an image to be processed, and perform dark area recognition on the image to be processed to obtain a recognition result. The recognition result is sent to the fill light system 102. The fill light system 102 receives the recognition result sent by the image acquisition system 101, and the recognition result includes the location of the dark area in the image to be processed (i.e., the location of the area to be filled with light).

[0054] The fill light system 102 includes a light source control circuit, a light source, and a fill light lens. The light source control circuit adjusts the position of the light emitting chip based on the position of the dark area. The fill light lens and the light emitting chip cooperate to adjust the fill light angle and fill light energy distribution.

[0055] based on Figure 1 The system architecture diagram of the present application provides a fill light method, which is applied to an image acquisition device, such as Figure 2 As shown, the following steps are included:

[0056] Step 201: Acquire an image to be processed.

[0057] Specifically, the image acquisition device may be a video camera, a still camera, etc.

[0058] In some embodiments, the image acquisition device further includes a fill light lens adapted to the light emitting chip, the fill light lens being used to adjust the fill light angle and fill light energy distribution according to the position of the light emitting chip. The light source includes a light emitting chip with position adjustment function, a reference base, and a silicone body.

[0059] For example, if Figure 3 As shown, the image acquisition device includes a fill light lens 301, a silicone body 302, a light-emitting chip 303, and a reference base 304. The light-emitting chip is located on the reference base, surrounded by the silicone body, and the fill light lens is located on the outer layer of the silicone body. In the embodiment of the present application, the fill light lens is adapted to the light-emitting chip, and the light-emitting chip and the fill light lens jointly adjust the fill light angle and fill light energy distribution.

[0060] Step 202: Perform dark area recognition on the image to be processed to obtain a recognition result.

[0061] Specifically, an image processing (ISP) algorithm can be used to divide the image to be processed into multiple areas to be identified, and then determine the grayscale value of each area to be identified. When the grayscale value of a certain area to be identified is less than a preset threshold, the area to be identified is an area to be filled with light, that is, a dark area.

[0062] For example, an image A to be processed is obtained, divided into 100 regions to be identified, and then the grayscale value of each of the 100 regions to be identified is determined. If the grayscale value of the region to be identified is less than 80, the region to be identified is a dark area.

[0063] Step 203: If the recognition result indicates that there is an area to be light-filled in the image to be processed, the position of the light-emitting chip in the image acquisition device is adjusted based on the target position of the area to be light-filled in the image to be processed.

[0064] Specifically, if a dark area is detected in the image to be processed and requires fill light, the position of the light-emitting chip in the image acquisition device is adjusted based on the location of the dark area in the image to be processed. The dark area can be located anywhere in the image to be processed, for example, at the center of the image to be processed or at one of its four corners.

[0065] Adjusting the posture of the light-emitting chip in the image acquisition device means adjusting the position and / or angle of the light-emitting chip. The position of the dark area is different, and the degree of adjustment of the posture of the light-emitting chip is also different.

[0066] In actual applications, after adjusting the position of the light-emitting chip once, the expected effect may not be achieved. That is, the image to be processed re-captured by the image acquisition device after the position adjustment still contains dark areas. In this case, the above steps S201 to S203 are executed for the re-captured image to be processed. Similarly, after adjusting the position of the light-emitting chip multiple times, the final fill light result is obtained.

[0067] In some embodiments, a step size for adjusting the posture of the light-emitting chip can be set. The posture of the light-emitting chip is adjusted according to the step size each time, and then the image to be processed is recaptured. If it is identified that there are still dark areas in the image to be processed, the posture of the light-emitting chip is adjusted again based on the position of the dark area and the preset step size, and so on, until there are no dark areas in the captured image to be processed.

[0068] In an embodiment of the present application, by identifying dark areas in the captured image to be processed, the position of the light-emitting chip in the image acquisition device is adjusted accordingly, thereby achieving fill light for the image acquisition device without the need to introduce a zoom element for fill light. That is, while ensuring that the size of the image acquisition device is small, refined fill light for the image acquisition device is achieved.

[0069] In some embodiments, if the target position is one of the four corners of the image to be processed, the height of the light emitting chip relative to the reference base is increased.

[0070] The target position is the dark area of ​​the image to be processed. When the dark area is at the four corners of the image to be processed, the position of the light-emitting chip is raised according to the preset step size, that is, the height of the light-emitting chip compared to the reference base is increased, thereby expanding the fill light angle, weakening the center fill light, and increasing the fill light at the four corners to achieve uniform fill light for the entire picture. For example, if Figure 4 The height of the standard light emitting chip is shown as Figure 5 The figure shows the height of the light-emitting chip after it is raised.

[0071] It should be noted that the aforementioned increase in the height of the light-emitting chip relative to the reference base when the dark area is located at the four corners of the image to be processed is merely an example. In some scenarios, when the fill light lens is a curved lens, if the dark area is located at the four corners of the image to be processed, the height of the light-emitting chip relative to the reference base is reduced. This application does not specifically limit this. Subsequent posture adjustments for dark areas located at the center, one side, and one corner are also merely examples, not specific limitations.

[0072] In the embodiment of the present application, by increasing the height of the light-emitting chip compared to the reference base, the fill light angle of the light-emitting chip is increased, thereby fill light is provided to the four corners of the image to be processed without adding additional fill light equipment, thereby reducing the size of the equipment.

[0073] In some embodiments, if the target position is the center position of the image to be processed, the height of the light-emitting chip is reduced compared to the reference base.

[0074] Specifically, when the dark area is at the center of the image to be processed, the position of the light-emitting chip is lowered according to the preset step size, that is, the height of the light-emitting chip relative to the reference base is lowered, thereby increasing the center fill light intensity and reducing the fill light intensity at the four corners, thereby achieving uniform fill light for the entire image. Figure 6 It is the height of the light-emitting chip after it is lowered.

[0075] In the embodiment of the present application, by lowering the height of the light-emitting chip compared to the reference base, the fill light angle of the light-emitting chip is reduced, thereby fill lighting the center position of the image to be processed without adding additional fill light equipment, thereby reducing the size of the equipment.

[0076] In some embodiments, if the target position is a single-side position of the image to be processed, the corresponding first adjustment area in the light-emitting chip is determined based on the single-side position, and the corresponding second adjustment area in the light-emitting chip is determined based on the other side position corresponding to the single-side position; the height of the first adjustment area is increased compared to the reference base, and the height of the second adjustment area is lowered compared to the reference base.

[0077] Specifically, the light-emitting chip can be tilted in any direction. By tilting the light-emitting chip, the posture of the light-emitting chip and its relative position to the fill light lens can be changed. The single-side position can be the left, right, top, or bottom of the image to be processed. If the target position is one side, the position of the light-emitting chip corresponding to that side is the first adjustment area, and the other side of the light-emitting chip corresponding to that side is the second adjustment area. For the first adjustment area, the height of the light-emitting chip needs to be increased compared to the reference base. For the second adjustment area, the height of the light-emitting chip needs to be reduced compared to the reference base.

[0078] For example, Figure 7 As shown, if the left side of the image to be processed is a dark area and corresponds to the left side of the light-emitting chip, the left side of the light-emitting chip is set as the first adjustment area and the right side of the light-emitting chip is set as the second adjustment area. In this case, the left side of the light-emitting chip is raised and the right side of the light-emitting chip is lowered.

[0079] In the embodiment of the present application, the fill light angle and energy distribution are adjusted by tilting the light-emitting chip, so as to fill light the dark area on one side. Fill light on one side can be achieved without adding fill light equipment, thereby reducing the size of the equipment.

[0080] In some embodiments, if the target position is a single angle position of the image to be processed, the corresponding third adjustment area in the light-emitting chip is determined based on the single angle position; after lowering the height of the third adjustment area compared to the reference base, the height of the light-emitting chip compared to the reference base is increased.

[0081] Specifically, the single corner position can be the upper left corner, lower left corner, upper right corner, or lower right corner of the image to be processed. The position of the light-emitting chip corresponding to the single corner position of the image to be processed is determined as the third adjustment area. First, the height of the third adjustment area of ​​the light-emitting chip relative to the reference base is lowered. Then, maintaining this position, the entire light-emitting chip is raised to increase the height of the light-emitting chip relative to the reference base.

[0082] In the embodiment of the present application, by changing the inclination angle of the light-emitting chip and the height of the light-emitting chip compared to the reference base, fill light is achieved at a single angle position, that is, fill light can be achieved at a single side position without adding fill light equipment, thereby reducing the size of the equipment.

[0083] In order to better explain the embodiment of the present application, the following describes a fill light method provided by the embodiment of the present application in combination with a specific implementation scenario. The process of the method can be as follows: Figure 1 The image acquisition device shown executes, as Figure 8 As shown:

[0084] Step 801: Acquire an image to be processed.

[0085] Step 802: Perform dark area recognition on the image to be processed to obtain a recognition result.

[0086] Step 803: Determine whether there is a dark area in the image to be processed. If so, execute step 804; if not, terminate.

[0087] Step 804: Determine the position of the dark area in the image to be processed.

[0088] Step 805 : When the dark areas are located at the four corners of the image to be processed, increase the position of the light-emitting chip relative to the reference base, and return to step 801 .

[0089] Step 806 : When the dark area is located at the center of the image to be processed, lower the height of the light-emitting chip relative to the reference base, and return to step 801 .

[0090] Step 807 : When the dark area is located at one side of the image to be processed, determine a first adjustment region in the light-emitting chip based on the position of the dark area and a second adjustment region corresponding to the other side of the dark area.

[0091] Step 808 : Increase the height of the first adjustment area compared to the reference base, and decrease the height of the second adjustment area compared to the reference base, and then return to step 801 .

[0092] Step 809: When the dark area is located at a single angle position in the image to be processed, determine a third adjustment area in the light-emitting chip based on the position of the dark area.

[0093] Step 810 : lowering the height of the third adjustment region compared to the reference base, increasing the height of the light-emitting chip compared to the reference base, and returning to step 801 .

[0094] Step 811, end.

[0095] In an embodiment of the present application, by identifying dark areas in the captured image to be processed, the position of the light-emitting chip in the image acquisition device is adjusted accordingly, thereby achieving fill light for the image acquisition device without the need to introduce a zoom element for fill light. That is, while ensuring that the size of the image acquisition device is small, refined fill light for the image acquisition device is achieved.
