Description

Technical Field

[0001] The present disclosure relates to the field of computer technologies, and in particular, to a method, an apparatus, and an electronic device for adjusting the internal illumination of an electrical appliance. Background Art

[0002] Currently, a light strip is installed inside an electrical appliance to provide illumination for better observing the cooking state of food ingredients. However, overexposure occurs instantaneously when the light strip is turned on, and underexposure occurs instantaneously when the light strip is turned off, resulting in problems such as unclear image details. In related technologies, for the overexposure when the light strip is turned on instantaneously and the underexposure when the light strip is turned off instantaneously, existing HDR-enabled cameras are often expensive, and the captured food ingredients are somewhat too dark or too bright. Without an HDR camera, due to the limited dynamic range, overexposure often occurs in the high-light area, and the dark area may be too dark, unable to show sufficient details. As a result, existing solutions for adjusting the internal illumination of electrical appliances have problems such as incomplete resolution of overexposure and underexposure problems, unclear images, and high costs.

In a specific embodiment, the preset camera parameters include the first camera parameters corresponding to overexposure when the light strip switch state is on or the second camera parameters corresponding to underexposure when the light strip switch state is off. In a specific embodiment, the preset gear parameters include the first gear parameters corresponding to overexposure when the light strip switch state is on or the second gear parameters corresponding to underexposure when the light strip switch state is off. In a specific embodiment, the first camera parameters and the first gear parameters are the camera parameters and gear parameters when the first current internal image of the target electrical appliance currently collected satisfies a first preset condition during the process of adjusting the camera parameters of the preset camera device and the gear parameters of the light strip under overexposure conditions.

[0145] Step S209, when the first current brightness and the first target brightness indicate that the third current internal image is overexposed, adjust the first current gear parameter of the light strip and the first target camera parameter of the preset camera device, and jump to step S201. Based on the preset camera device, photograph the preset acquisition area inside the target electrical appliance to obtain the third current internal image.

[0146] In a specific embodiment, the above first target camera parameters include a first target gain and a first target exposure time. In a specific embodiment, the above first target camera parameters are obtained based on the first target brightness after adjusting the first current gear parameter, the first current brightness after adjusting the first current gear parameter, the first current exposure time of the preset camera device, and the first current gain of the preset camera device.

[0148] In a specific embodiment, as Figure 4 shown, adjusting the first current gear parameter of the light strip and the first target camera parameter of the preset camera device includes:

[0149] Step S401, lower the first current gear parameter.

[0150] Step S403, obtain the first current brightness after lowering the first current gear parameter, the first target brightness after lowering the first current gear parameter, the first current gain, and the first current exposure time.

[0151] In a specific embodiment, obtaining the first current brightness after the first current gear parameter is lowered and the first target brightness after the first current gear parameter is lowered may include: determining the first current brightness after the first current gear parameter is lowered and the first target brightness after the first current gear parameter is lowered based on the third current internal image collected after the first current gear parameter is lowered. In a specific embodiment, for the specific refinement of determining the first current brightness after the first current gear parameter is lowered based on the third current internal image collected after the first current gear parameter is lowered, reference may be made to step S203 above, which will not be elaborated here. In a specific embodiment, for the specific refinement of obtaining the first target brightness after the first current gear parameter is lowered based on the third current internal image collected after the first current gear parameter is lowered, reference may be made to step S205 and step S207 above, which will not be elaborated here.

[0152] In a specific embodiment, obtaining the first current gain and the first current exposure time above may be the real-time parameters of a preset camera device. Specifically, the first current gain and the first current exposure time may be directly read.

[0153] Step S405: Adjust the first target camera parameter based on the first current brightness after the first current gear parameter is lowered, the first target brightness after the first current gear parameter is lowered, the first current exposure time, and the first current gain.

Specifically, the formula for calculating the first target exposure time is where L obj is the first target brightness, L cur is the first current brightness, t cur is the first current exposure time, and t obj is the first target exposure time. The formula for calculating the first target gain is where L obj is the first target brightness, L cur is the first current brightness, G cur is the first current gain, and G obj is the first target gain.

[0155] In the above embodiments, in the case of overexposure, by adjusting the light strip gear, and based on the obtained current brightness after adjusting the light strip gear and the target brightness after adjusting the light strip gear, the obtained real-time current gain and real-time current exposure time are used to adjust the target gain and target exposure time of the camera, so as to achieve the technical effect of automatic image exposure control and optimization, which can help ensure that the target electrical appliance images can maintain good visibility and image quality in the case of overexposure.

When the third current internal image meets the first preset condition, the third current internal image is neither underexposed nor overexposed; optionally, when the first current brightness is equal to the first target brightness, it can be determined that the third current internal image meets the first preset condition.

[0158] In a specific embodiment, the third current internal image when meeting the first preset condition is the first current internal image.

[0163] The above step S207 of determining the first target brightness based on the first region information, the second region information, the third region information, and the first preset weight information includes:

[0164] Based on the first region information, the second region information, the third region information, the adjusted preset weight information corresponding to the first target region, and the preset weight information corresponding to other regions, determine the first target brightness, where the other regions are the two regions remaining from the food material region, the light strip region, and the background region excluding the first target region;

[0165] The above step S211 of taking the current first current gear parameter as the first gear parameter and the current first target camera parameter as the first camera parameter when the first current brightness and the first target brightness indicate that the third current internal image meets the first preset condition includes:

[0166] When the first current brightness and the first target brightness indicate that the image of the first target region in the third current internal image meets the first preset condition, take the current first current gear parameter as the first gear parameter and the current first target camera parameter as the first camera parameter.

[0167] In a specific embodiment, the above image of the first target region is the regional image of the first target region in the third current internal image.

[0168] In a specific embodiment, the positioning operation of the first target region in the above third current internal image can be triggered by touch operation methods such as clicking or long-pressing the region where the target region is located in the third current internal image.

[0169] In the above embodiment, by clicking on the target region and adjusting the preset weight information, the system can more accurately locate and enhance the specific target region, thereby optimizing the visual performance of the target region in the image. Using multi-region information and weight adjustment, the system can intelligently determine the brightness level of each region, making the target region more prominent in the overall image and achieving more precise target highlighting and visual optimization.

[0170] In a specific embodiment, as Figure 5 shown, the above second camera parameter and the above second gear parameter are obtained by the following method:

[0171] Step S501, based on a preset camera device, photograph a preset acquisition region inside the target electrical appliance to obtain a fourth current internal image, where the preset acquisition region includes a food material region, a light strip region, and a background region, and the background region is the region remaining from the preset acquisition region excluding the food material region and the light strip region.

[0176] In a specific embodiment, the second preset weight information includes preset weight information corresponding to the food ingredient region, the light strip region, and the background region respectively. In a specific embodiment, the sum of the preset weight information corresponding to the food ingredient region, the light strip region, and the background region respectively is 1. Optionally, the second preset weight information can be preset in combination with actual application requirements.

[0178] Step S509: In the case where the second current brightness and the second target brightness indicate that the fourth current internal image is underexposed, adjust the second current gear parameter of the light strip and the second target camera parameter of the preset camera device, and jump to step S501 to capture the preset acquisition region inside the target electrical appliance based on the preset camera device to obtain the fourth current internal image.

[0179] In a specific embodiment, the above second target camera parameters include a second target gain and a second target exposure time. In a specific embodiment, the above second target camera parameters are obtained based on the second target brightness adjusted by the second current gear parameter, the second current brightness adjusted by the second current gear parameter, the second current exposure time of the preset camera device, and the second current gain of the preset camera device.

[0184] Based on the first current brightness after the second current gear parameter is increased, the second target brightness after the second current gear parameter is increased, the second current exposure time, and the second current gain, increase the second target camera parameter.

[0185] Step S511, when the second current brightness and the second target brightness indicate that the fourth current internal image meets the second preset condition, use the current second current gear parameter as the second gear parameter and the current second target camera parameter as the second camera parameter.

[0186] In a specific embodiment, the above-mentioned second preset condition can be set in combination with the actual application. When the fourth current internal image meets the second preset condition, the fourth current internal image is neither underexposed nor overexposed; optionally, when the second current brightness is equal to the second target brightness, it can be determined that the fourth current internal image meets the second preset condition.

[0187] In a specific embodiment, the fourth current internal image when meeting the second preset condition is the second current internal image.
