Description

Technical Field

[0001] This disclosure relates to the field of camera technology, and in particular to a method, apparatus, computer device, readable storage medium, and program for adjusting camera white balance. Background Technology

[0002] White balance drift occurs when a camera switches between different, relatively stable environments (e.g., near a window, facing indoors and outdoors, where physical parameters are stable at any given moment). Because white balance has a memory or statistical function, inconsistencies can occur even under the same conditions. For example, using the same parameters and the same camera module, when the light source color temperature gradually increases to its highest level and then cycles back up, the same color temperature can result in different visuals. Similarly, with the same module and parameters, under the same color temperature and illuminance, white balance drift can appear either too warm or too cool. Summary of the Invention

[0023] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0024] In this embodiment of the disclosure, the white balance of the camera module can be adjusted by obtaining the number of times the white balance of the camera module shifts to a warmer or cooler state at the first color temperature; and by adjusting the white balance point of the camera module based on the number of times the white balance of the camera module shifts to a warmer or cooler state at the first color temperature.

[0025] The following is a brief explanation of some of the terms used in this disclosure:

[0026] In professional video production, white balance refers to the sensor's response to red, green, and blue chromatic auras varies at different color temperatures, resulting in a non-1:1:1 white reproduction. Therefore, processing is needed to ensure that white is reproduced at any color temperature, and the sensor's response is calibrated to produce a 1:1:1 output.

[0027] Color temperature is a unit of measurement that indicates the color components in light. Theoretically, blackbody temperature refers to the color of an absolute blackbody after it has been heated from absolute zero (-273°C). When heated, a blackbody gradually changes from black to red, then to yellow, then to white, and finally emits blue light. The spectral composition of the light emitted by a blackbody at a certain temperature is called the color temperature at that temperature, and the unit of measurement is "K" (Kelvin).

[0028] The solutions provided in this disclosure involve technologies such as camera white balance.

[0029] Figure 1 A schematic diagram of an exemplary system architecture 100 to which the camera white balance adjustment method of the present disclosure can be applied is shown.

[0030] like Figure 1 As shown, system architecture 100 may include one or more of terminals 101, 102, and 103, a network 104, and a server 105. Network 104 is the medium used to provide a communication link between terminals 101, 102, and 103 and server 105. Network 104 may include various connection types, such as wired or wireless communication links or fiber optic cables, etc.

[0031] It should be understood that Figure 1 The number of terminals, networks, and servers shown is merely illustrative. Depending on implementation needs, there can be any number of terminals, networks, and servers. For example, server 105 could be a server cluster consisting of multiple servers.

[0032] Terminals 101, 102, and 103 interact with server 105 via network 104, and can receive or send messages, etc. Terminals 101, 102, and 103 can be various electronic devices with displays, including but not limited to smartphones, tablets, laptops, and desktop computers, etc.

[0033] Server 105 can be a server that provides various services. For example, after terminal 103 (or terminal 101 or 102) sends a camera white balance adjustment request to server 105, server 105 can obtain the number of times the camera module's white balance shifts to warmer or cooler under the first color temperature; based on the number of times the camera module's white balance shifts to warmer or cooler under the first color temperature, server 105 can adjust the white balance setting of the camera module, thereby achieving camera white balance adjustment.

[0034] The terminal can be a mobile phone (such as terminal 101), a tablet computer (such as terminal 102), or a desktop computer (such as terminal 101), etc., without limitation. The terminal can display applications, such as applications for adjusting camera white balance. Figure 1 The terminals mentioned are only a portion of the devices cited in this disclosure; the terminals are not limited to these. Figure 1 The equipment listed in the text.

[0035] In existing technologies, the common approach to white balance drift is to recalibrate the white balance and fit the Planck curve to make the white balance more stable and the algorithm more efficient.

[0036] Figure 2 This is a flowchart illustrating a camera white balance adjustment method provided in this disclosure. The method provided in this disclosure can be... Figure 1 The methods described in this embodiment are executed by a terminal or server, or by interaction between a terminal and a server. However, this disclosure is not limited thereto; the methods of this disclosure can be executed by any processor with computing power.

[0037] like Figure 2 As shown, the method provided in this disclosure embodiment may include the following steps.

[0038] In step S210, the number of times the camera module's white balance shifted to warmer and cooler under the first color temperature is obtained.

[0039] In this step, the terminal or server obtains the number of times the camera module's white balance shifts towards a warmer or cooler bias at the first color temperature. The number of these shifts can be obtained through experimental verification and statistical analysis, and then input into the terminal or server. For example, the number of white balance shifts towards a warmer or cooler bias at the first color temperature can be counted 100 times consecutively, and the number of each shift can be recorded.

[0040] "Warmer color shift" refers to images taken by the camera module having a reddish tint, while "cooler color shift" refers to images taken by the camera module having a bluish tint. Additionally, the primary color temperature can be any color temperature.

[0041] In step S220, the white balance setting of the camera module is adjusted according to the number of times the white balance shifts to warmer and cooler under the first color temperature.

[0042] In this step, the terminal or server adjusts the white balance setting of the camera module according to the number of times the white balance shifts to warmer and cooler at the first color temperature.

[0043] Figure 2 The method for adjusting the camera white balance involves obtaining the number of times the camera module's white balance shifts towards a warmer or cooler tone at a first color temperature; and adjusting the white balance point of the camera module based on the number of times the white balance shifts towards a warmer or cooler tone at the first color temperature, thereby achieving the adjustment of the camera white balance.

[0044] Figure 3 This is a flowchart illustrating a method for adjusting the white balance of a camera module based on the number of times the white balance shifts towards a warmer or cooler tone at the first color temperature, according to an embodiment of this disclosure. The method provided in this embodiment can be... Figure 1 The methods described in this embodiment are executed by a terminal or server, or by interaction between a terminal and a server. However, this disclosure is not limited thereto; the methods of this disclosure can be executed by any processor with computing power.

[0045] like Figure 3 As shown, the method provided in this disclosure embodiment may include the following steps.

[0046] In step S310, when the number of times the white balance drifts to a warmer position is greater than the number of times it drifts to a cooler position, the white balance point is moved towards the cooler position.

[0047] In this step, when the number of times the white balance drifts to a warmer position is greater than the number of times it drifts to a cooler position, the terminal or server moves the white balance point to a cooler position.

[0048] Figure 4 This is a flowchart illustrating a method for shifting the white balance point towards a cooler position when the number of white balance drifts to a warmer position exceeds the number of drifts to a cooler position, as provided in this embodiment of the disclosure. The method provided in this embodiment can be... Figure 1 The methods described in this embodiment are executed by a terminal or server, or by interaction between a terminal and a server. However, this disclosure is not limited thereto; the methods of this disclosure can be executed by any processor with computing power.

[0049] like Figure 4 As shown, the method provided in this disclosure embodiment may include the following steps.

[0050] In step S410, when the number of times the white balance shifts to a warmer tone is greater than the number of times it shifts to a cooler tone, the white balance point is moved to a cooler position so that the probability of the white balance shifting to a cooler tone at the first color temperature is greater than the first proportion.

[0051] In this step, when the number of times the white balance shifts to a warmer tone is greater than the number of times it shifts to a cooler tone, the terminal or server moves the white balance point to a cooler position, so that the probability of the white balance shifting to a cooler tone at the first color temperature is greater than the first proportion.

[0052] In one embodiment, when the number of times the white balance shifts to a warmer bias is greater than the number of times it shifts to a cooler bias, shifting the white balance point towards a cooler bias includes: when the number of times the white balance shifts to a warmer bias is greater than the number of times it shifts to a cooler bias, shifting the white balance point towards a cooler bias, so that the probability of the camera module shifting to a cooler bias at the first color temperature is greater than a first proportion. The first proportion is, for example, 90% or higher, so that the camera module substantially shifts to a cooler bias in the white balance at the first color temperature.

[0053] In one embodiment, shifting the white balance point towards a cooler position includes: increasing the intensity of the blue component in the white balance.

[0054] In step S320, when the number of times the white balance shifts to a warmer position is less than the number of times it shifts to a cooler position, the white balance point is moved towards a warmer position.

[0055] In this step, when the number of times the white balance drifts to a warmer position is less than the number of times it drifts to a cooler position, the terminal or server moves the white balance point to a warmer position.

[0056] Figure 5 This is a flowchart illustrating a method for shifting the white balance point towards a warmer position when the number of white balance drifts to a warmer position is less than the number of white balance drifts to a cooler position, according to an embodiment of this disclosure. The method provided in this embodiment can be... Figure 1 The methods described in this embodiment are executed by a terminal or server, or by interaction between a terminal and a server. However, this disclosure is not limited thereto; the methods of this disclosure can be executed by any processor with computing power.

[0057] like Figure 5 As shown, the method provided in this disclosure embodiment may include the following steps.

[0058] In step S510, when the number of times the white balance shifts to a warmer tone is less than the number of times it shifts to a cooler tone, the white balance point is moved to a warmer position so that the probability of the camera module shifting to a warmer tone at the first color temperature is greater than the second proportion.

[0059] In this step, when the number of times the white balance shifts to a warmer tone is less than the number of times it shifts to a cooler tone, the terminal or server moves the white balance point to a warmer position, so that the probability of the camera module shifting to a warmer tone at the first color temperature is greater than the second proportion.

[0060] In one embodiment, when the number of times the white balance shifts to a warmer bias is less than the number of times it shifts to a cooler bias, shifting the white balance point towards a warmer position includes: shifting the white balance point towards a warmer position when the number of times the white balance shifts to a warmer bias is less than the number of times it shifts to a cooler bias, so that the probability of the camera module shifting to a warmer bias at the first color temperature is greater than a second proportion. The second proportion is, for example, 90% or higher, so that the camera module substantially maintains a warmer white balance at the first color temperature.

[0061] In one embodiment, shifting the white balance point towards a warmer position includes: increasing the intensity of the red component in the white balance.

[0062] Figure 3 The method described herein ensures that the camera module's white balance is substantially warmer or cooler at the first color temperature, minimizing the possibility of both simultaneously exhibiting warmer or cooler white balance shifts at the first color temperature. When the camera module's white balance is substantially warmer or cooler at the first color temperature, subsequent adjustments can be made to the intensity of the blue or red component in the white balance to ensure accurate white balance in the image output by the camera module.

[0068] In one embodiment, the adjustment unit 620 is further configured to move the white balance point to a cooler position when the number of times the white balance drifts to a warmer position is greater than the number of times it drifts to a cooler position; and to move the white balance point to a warmer position when the number of times the white balance drifts to a warmer position is less than the number of times it drifts to a cooler position.

[0069] In one embodiment, the adjustment unit 620 is further configured to move the white balance point to a cooler position when the number of times the white balance shifts to a warmer position is greater than the number of times it shifts to a cooler position, so that the probability of the white balance shifting to a cooler position at the first color temperature is greater than a first proportion.
