For example, when the illumination module is turned on, the camera module acquires an image corresponding to the illuminated area. The image may be a partial or full area image of the illuminated area, and the shooting range may be determined by presetting the shooting angle of the camera module.
In one embodiment, such as in a kitchen cooking setting, the range hood includes an illumination module for illuminating a cooktop area and a camera module for capturing images of the cooktop area. Generally, a region at a rear position of the cooking range region or a region far from the user is an area with insufficient illumination and is easily blocked by the cooking appliance, so that it may be preset that the camera module mainly photographs the partial region in the cooking range region.
In one embodiment, the home appliance may include a plurality of lighting modules respectively distributed at different positions of the home appliance, the plurality of lighting modules illuminating a preset illuminated area.
The camera module can shoot a preset illuminated area once, and can shoot each illuminated area sequentially according to the setting.
S20 is to perform a partition process on the first image according to the distribution of the plurality of lighting modules in the home appliance to obtain a plurality of partition areas, wherein each lighting module corresponds to at least one partition area in the first image.
After a first image of the illuminated area is acquired, the first image is image processed to determine the brightness of certain areas in the image. For example, the first image is partitioned according to the distribution condition or the position information of the lighting modules, which can be realized by establishing the corresponding relationship between each lighting module and the partitioned area.
As shown in fig. 5, for example, the household appliance includes lighting modules L1, L21, L22, L23, and L24, the first image is partitioned into 18 partition areas, and the corresponding relationship between the lighting modules and the partition areas is shown in the figure, where the default brighter area corresponds to L1, and the other darker areas correspond to L21, L22, L23, and L24.
In some embodiments, in order to increase the accuracy of the lighting control, the first image may be subdivided into regions, and each lighting module may set more individually controlled light bead segments.
S30, obtaining the brightness value of each partition area in the first image, and determining the brightness of each partition area.
In some embodiments, the brightness value corresponding to each partition region may be obtained through the image information. For example, the first color space of each partition area in the first image is converted into the second color space including the luminance channel, and the luminance value corresponding to the luminance channel is obtained. Typically the first color space may be an RGB color space and the second color space may be a Lab color space and comprise a luminance channel.

The preset threshold value here may be preset based on experimental or empirical data.
After the partition area with insufficient brightness is determined, the lighting module corresponding to the partition area with insufficient brightness can be determined according to the corresponding relationship between the lighting module and the partition area, and the lighting power of the lighting module is controlled and adjusted.
By the control method, the brightness of the illuminated area can be intelligently adjusted, manual adjustment of illumination by a user is avoided, both hands of the user are released, the problem that the illuminated area is not uniformly illuminated or shadows are locally formed is solved, and illumination control is more accurate. In addition, the method improves the overall illumination uniformity and also improves the user experience.

The method is different from the method shown in fig. 1 in that a first image to be subjected to partition processing is obtained after an image acquired by the camera module is processed. The step is used for identifying image information which does not need to judge the brightness in the image and deleting the image information. For example, in a kitchen scene, the position of a pot in a cooking bench area is not insufficient compared with the area behind the cooking bench; instead, the cooker is usually shielded, so that the area behind or beside the cooking bench has insufficient light or shadow. As shown in fig. 5, the circle portion in the figure is the identified area where the pot is located, and the image information of the circle portion can be removed from the image to be partitioned, that is, the brightness of the image of the circle portion does not need to be determined.
In some embodiments, the household appliance is a range hood and the illuminated area is a cooktop. The first image can be obtained by acquiring a second image of the hearth area, identifying the cooking utensil in the second image, and removing the image information of the area corresponding to the cooking utensil for subsequent image partition processing and brightness judgment.
And S21, partitioning the first image according to the distribution of a plurality of lighting modules in the household appliance to obtain a plurality of partitioned areas, wherein each lighting module corresponds to each partitioned area in the first image.
S31, acquiring the brightness value of each subarea area in the first image, and judging the brightness of each subarea area.
And S41, when the brightness of a certain subarea is judged to be insufficient, acquiring the illumination module information corresponding to the subarea with insufficient brightness, and controlling the illumination module to adjust the illumination power.
The steps S21-S41 are similar to the steps S20-S40, and reference is made to the above description for specific embodiments.

For example, when the household appliance is a range hood, the particular distribution of the lighting modules may be in the manner shown in fig. 7. Referring to fig. 3, the first partition area corresponds to the main illuminating lamp L1, and the second partition area corresponds to the auxiliary illuminating lamps L21, L22, L23, and L24, generally, the illumination brightness ratio of the first partition area is relatively uniform, and the brightness-deficient area can be determined by comparing the brightness difference between the first partition area and the second partition area, so as to determine whether the corresponding auxiliary illuminating module needs to be adjusted.
In some embodiments, to further determine which areas in the second partition area have insufficient brightness, the determination may be further performed by determining whether a brightness difference between some areas in the second partition area and a preset brightness value is higher than a preset threshold; or, the method may further determine the sub-area with insufficient brightness by determining whether a brightness difference between the brightness value of each second sub-area and the average brightness of the sub-area is higher than a preset threshold, and control the auxiliary lighting module corresponding to the sub-area.
S401, when the brightness of a certain subarea area is judged to be insufficient, the information of the lighting module corresponding to the subarea area with insufficient brightness is obtained, and the lighting module is controlled to adjust the lighting power.

When a lighting module that requires power adjustment is determined, the power of the lighting module may be adjusted in steps. After adjusting a certain brightness proportion, judging whether the power of the lighting module reaches a limit value. If the limit is reached, stopping power regulation; if not, the camera module recaptures the image of the illuminated area and proceeds to steps S10-S40 or S11-S41 in the previous embodiment.
