Description

Method for testing focus moving time based on image page average brightness comparison

Technical Field

The invention relates to the field of testing of intelligent digital video terminal display technology, in particular to a method for testing focus movement time based on image page average brightness comparison.

Background

Most of the functions of the smart television need to be selected from application pages. The page is generally provided with a plurality of view modules, each view module is provided with a corresponding link, and a user can enter the corresponding link by selecting a focus of the view module through the remote controller.

The operation of the remote controller by the user has higher operation attention to the movement of the page focus, particularly the fluency of the up-down and left-right movement of the focus, particularly when the user does not have a specific target. The user can respond to the operation requirement of the focus in real time no matter the main menu or the application of the intelligent television is operated; especially like browsing the main scene page focus, the user may operate quickly and frequently, e.g. such experience interaction times exceeding 3-5 seconds are hardly acceptable to the user. It becomes necessary to test the response and moving speed of the operating focus of the television remote controller.

The current focus movement test is completed by manually operating a stopwatch. Often, the test is inaccurate under the condition of short movement time of the focus, the test can be repeated for a plurality of times, and the data is unstable; in addition, the visual influence of the test scene on the testers can be wrong even if the test process is slightly and manually reflected; resulting in poorer referencing of shorter duration data. If the focus movement is tested by shooting a video, a tester needs to shoot images of the manual operation remote controller and the focus movement in the video at the same time, the action and the angle are clear and distinguishable, and then the manual measurement and calculation are performed by editing software; the method takes a long time to shoot the video, and seriously affects the testing efficiency.

Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.

On the contrary, the application is intended to cover any alternatives, modifications, equivalents, and variations that may be included within the spirit and scope of the application as defined by the appended claims. Further, in the following detailed description of the present application, specific details are set forth in order to provide a more thorough understanding of the present application. The present application will be fully understood by those skilled in the art without a description of these details.

A method for testing the focus movement time based on the image page average brightness comparison according to the embodiment of the present application will be described in detail with reference to fig. 1-2. It is noted that the following examples are only for explaining the present application and are not limiting of the present application.

As shown in fig. 1-2, the method for testing the focus movement time based on the image page average brightness comparison comprises the following steps:

the application page focus moving process of the intelligent television comprises two parts, namely event refreshing and focus moving, referring to figure 1; as the focus moves from one module to another in an application or menu, the character, color, shape, and view module size of the view module are all changing gradually: the characters and the contents of the module are changed, the page is changed from conversion, blurring and ghost to clear, the focus frame is reduced from the defocus of the previous frame to the focus magnification of the next frame, and the brightness of the corresponding image is correspondingly changed until the page is stable.

The application page (set as a static page) of the intelligent television needs to test more than one control on the page with the focal point moving time length; in the focus moving process, the control is required to have gradual change of text, color and shape; after the focus frame moves and the event refreshing is completed, the image of the application page is stable and unchanged.

In the current television in real-time graphics and video application processing, the SDRAM has strong computing power, and the average brightness (ABL for short) of each page of picture can be obtained in real time. When the television picture moves in focus, the system acquires the average brightness of the corresponding picture and writes the average brightness into the corresponding register; when moving, reading the average brightness once every m time periods (unit ms), and comparing the average brightness with the data when the television focus is not moving; if the data are inconsistent, comparing after reading at intervals of m until the data are not changed, judging that the page focus of the television has completed moving, and recording comparison times n; otherwise, continuing.

Taking the right shift test of the top focus of the main scene of the television as an example for test flow illustration, see the second drawing for details:

before the focus is moved:

firstly, an ABL register of a current picture of a television is read, average brightness is obtained, and the average brightness is recorded as m0;

secondly, setting a counter, and clearing 0; setting a timer to time for 10ms;

focus movement test:

step 1: sending a right key instruction of the remote controller through the serial port;

step 2: opening a timer; when timing is up, an ABL register of the current picture of the television is read, the comparison between m1 and m0 is recorded, and the counter is added with 1;

step 3: if the data are inconsistent, executing the step 2;

step 4: if the data are consistent, a counter m is obtained;

the focal point movement is completed:

calculating the product of the accumulated m and the value of the accumulated counter, and recording the product as the time length of focus movement;

ready to test the next.

The characteristics of focus movement are utilized, whether the focus movement is finished is positioned according to the average brightness change in the picture change process, the time of the focus movement is confirmed, and human factors are thoroughly eliminated.

The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
