DESCRIPTION OF EMBODIMENTS
To make the objectives, technical solutions, and advantages of the present disclosure more clear, the followings further describe the embodiments of the present disclosure in detail with reference to the accompanying drawings.
Embodiment 1
Referring to FIG. 1, FIG. 1 shows a flowchart of an interface adjustment method according to Embodiment 1 of the present invention. The interface adjustment method may be used in a terminal having an image capture device such as a camera, and the terminal may be a smart TV, a smart phone, a tablet computer, or the like. The interface adjustment method includes:
Step 102: Capturing a current image. The camera in the terminal may capture a current image at current time in a current environment, for example, a front-facing camera of a smart TV captures a current image of an environment in front of a TV screen of the smart TV. The camera may be a built-in camera, or may be an external camera.
Step 104: Analyzing current ambient brightness according to the current image. The terminal may analyze current ambient brightness according to the current image captured by the camera.
Step 106: Adjusting display of an interface according to the current ambient brightness. After obtaining the current ambient brightness through analysis, the terminal may select one set of interface from several sets of preset interfaces for display. For example, three sets of interfaces are preset in the terminal, which are a high-brightness interface, a normal interface, and a soft interface respectively. Assuming that the terminal finds by analysis that the current ambient brightness is relatively low, the terminal may select the soft interface as a to-be-displayed interface.
Thus, according to the interface adjustment method provided by this embodiment of the present invention, current ambient brightness is obtained by capturing a current image and analyzing the current image, thereby implementing interface adjustment. Such method solves the problem that an existing interface adjustment method can only be used in a smart TV having a light sensor, and a terminal having an image capture function can adjust an interface based on the ambient brightness.
Embodiment 2
Referring to FIG. 2, FIG. 2 shows a flowchart of an interface adjustment method according to Embodiment 2 of the present invention. The interface adjustment method may be used in a terminal having an image capture device such as a camera, and the terminal may be a smart TV, a smart phone, a tablet computer, or the like. The interface adjustment method includes:
Step 202: Capturing a current image. The camera in the terminal may capture a current image at current time in a current environment. For example, a front-facing camera of a smart TV captures a current image of an environment in front of a TV screen. The camera may be a built-in camera, or may be an external camera.
The terminal may also capture a current image at a preset time interval, and the preset time interval may be set by a user or set by default in the terminal.
Step 204: Analyzing current ambient brightness according to the current image. The terminal may analyze current ambient brightness according to the current image captured by the camera. Specifically, the terminal may determine the current ambient brightness according to brightness of some or all pixels in the current image, for example, the terminal may use an average brightness value or a total brightness value of some or all pixels as the current ambient brightness.
Specifically, any one of the following three analysis methods may be used to implement this step.
The first method: an average brightness value of all pixels in the current image is calculated and the average brightness value is used as the current ambient brightness. For example, if the size of the image captured by the camera is 640*480 pixels, the terminal first accumulates brightness data of 640*480=307200 pixels, then divides the accumulated brightness data by 307200 to obtain an average brightness value, and uses the average brightness value as the current ambient brightness, where a value rang of the average brightness value may be (0, 255).
The second method: a local area is extracted from the current image, an average brightness value of the extracted local area is calculated, and the average brightness value is used as the current ambient brightness.
For example, if the size of the image captured by the camera is 640*480 pixels, the terminal first extracts, at a central area of the image, an area having 320*240 pixels as a local area, then accumulates brightness data of 320*240=76800 pixels, divides the accumulated brightness data by 76800 to obtain an average brightness value, and uses the average brightness value as the current ambient brightness, where a value rang of the average brightness value may be (0, 255). Other areas of the image, e.g., left, right, top, or bottom areas, may also be used.
Certainly, the terminal may also evenly extract multiple local areas from the current image for calculation, for example, the terminal evenly extracts multiple areas having a size of 16*16 pixels from the current image for calculation.
The third method: sample pixels are extracted from the current image, an average brightness value of the extracted sample pixels is calculated, and the average brightness value is used as the current ambient brightness.
For example, if the size of the image captured by the camera is 640*480 pixels, the terminal extracts, in a column direction, one row at intervals of three rows as a sample row, then extracts one sample pixel at intervals of three pixels in each sample row, and finally, calculates an average brightness value of the extracted sample pixels, and uses the average brightness value as the current ambient brightness. Similarly, the sample pixels may also be extracted from various rows instead of columns, or be extracted from other different patterns.
Step 206: Selecting one set of interface from at least two sets of preset interfaces as a to-be-displayed interface according to the current ambient brightness and a preset relationship, where the preset relationship is a one-to-one correspondence between the brightness ranges of the current ambient brightness and the interfaces.
The terminal may store at least two sets of interfaces in advance. For example, the terminal stores three sets of interfaces in advance, namely, a high-brightness interface, a normal interface, and a soft interface respectively. The terminal may further store, in advance, a one-to-one correspondence between the brightness range of the current ambient brightness and the interfaces as a preset relationship. For example, when the current ambient brightness belongs to a brightness range [0-64], the current ambient brightness corresponds to the high-brightness interface; when the current ambient brightness belongs to a brightness range [65-128], the current ambient brightness corresponds to the common interface; and when the current ambient brightness belongs to a brightness range [129-255], the current ambient brightness corresponds to the soft interface.
After calculating the current ambient brightness in the previous step, the terminal selects one set of interface from the at least two sets of preset interfaces as a to-be-displayed interface according to the current ambient brightness and the preset relationship. For example, when the current ambient brightness calculated by the terminal is 202, and according to the preset relationship, the soft interface may be selected as the to-be-displayed interface.
The interface may be a system interface, or may be an interface of an application program. The interface may include one or more of a background pattern, background brightness, background color contrast, and background color saturation.
Additionally, in specific implementation, all the three steps of this embodiment may be implemented by a system, or may be implemented by an application program; or the first two steps may be implemented by a system and the last step may be implemented by an application program. The ultimate purpose is to make both the system interface and the application program interface capable of adjusting interface display by ambient brightness.
Thus, according to the interface adjustment method provided by this embodiment of the present invention, current ambient brightness is obtained by capturing a current image and analyzing the current image, thereby implementing interface adjustment. Such method solves the problem that an existing interface adjustment method can only be used in a smart TV having a light sensor, and any terminal having an image capture function can adjust an interface by ambient brightness. In addition, by extracting a local area or sample pixels to calculate brightness data, the amount of calculation can be reduced, and the display adjustment of an interface can be completed more quickly.
