Embodiment Construction

[0046] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] The present invention provides a test method for reappearance rate, referring to figure 1 , in one embodiment, described reappearance rate testing method comprises the following steps:

[0048] Step S101, start the redisplay rate test mode of the terminal, and select an image format;

[0049] In this preferred embodiment, the terminal starts the redisplay rate test mode and selects an image format. The terminal is a TV or computer with image display function, and the image formats include 480, 720, 1080, 2160..., corresponding to 640*480 pixels, 1280*720 pixels, 1920*1080 pixels, 3840*2160 pixels, respectively pixel…. It can be understood that the image formats may also be 640, 1280, 1920, 3840, etc. or other custom formats representing these pixels respectively. In this embodiment, the type of the image is...

Abstract

The invention discloses a method for testing the redisplay rate, which includes the following steps: starting the redisplay rate test mode of the terminal, and selecting an image format; according to the selected image format, calling the pre-stored and the and display the image to be tested corresponding to the image format; read the boundary primary color value of the displayed image to be tested; calculate and obtain the reappearance rate of the direction corresponding to the boundary according to the boundary primary color value. The invention also discloses a terminal. The invention can avoid external equipment and human participation, and improve the efficiency and accuracy of the reappearance rate test.

Description

technical field [0001] The invention relates to the technical field of image testing, in particular to a method and terminal for testing a reappearance rate. Background technique [0002] The image redisplay rate is an important indicator of TV image testing, which reflects the completeness of the displayed image by the percentage of the actual displayed image size to the original image size. The traditional test method is to input an image with a specific scale identification signal into the instrument, and rely on human eyes to confirm the actual displayed image scale to determine whether the redisplay rate is qualified. Whether the current rate is qualified. The test methods used above have at least the following defects: Due to the influence of external environmental factors, such as test distance, external light, test signals and measuring instruments, etc., as well as human factors, etc., will cause large errors, and at the same time cannot accurately measure Whether...
