Method for Determining Residual Image Level of Display Device and Detection Device |
| 摘要 |
A method for determining a residual image level of a display device and a detection device. The method includes: lighting the display device based on a setting image type, and setting a plurality of detection positions on the display device based on the setting image type; converting a display image on the display device into a grayscale image with a setting level; detecting an actual brightness value of each detection position within a setting time after converting into a grayscale of the setting level; for each detection position, acquiring a brightness variation index of the detection position based on the acquired actual brightness value and a corresponding predetermined relationship between the actual brightness value and a theoretical brightness value of the grayscale of the setting level; and acquiring an residual image level of the display device in the grayscale of the setting level based on the acquired brightness variation index. |

1. A residual image level determining method of a display device, comprising:
lighting the display device based on a setting image type, and setting a plurality of detection positions on the display device based on the setting image type; converting a display image on the display device into a grayscale image with a setting level; detecting an actual brightness value of each detection position within a setting time after converting into a grayscale of the setting level; for each detection position, acquiring a brightness variation index of the detection position based on the acquired actual brightness value and a corresponding predetermined relationship between the actual brightness value and a theoretical brightness value of the grayscale of the setting level; and acquiring a residual image level of the display device in the grayscale of the setting level based on the acquired brightness variation index and a corresponding predetermined relationship between brightness variation indexes and residual image levels. |
