Description

Dynamic image detecting device and detecting method of panel IC

The invention provides a dynamic image detecting device and a detecting method capable of performing continuous continuous motion image detection to improve the quality of IC detection.

Press, after the panel IC is completed, it must be selected for static image detection or motion image detection according to the function to eliminate the defective product. The static image detection system is used for image comparison of single static image files to be applied. For example, the IC of the electronic photo frame panel transmits a static image file (such as a picture file) to the IC to be tested to detect the quality of the still image data output by the IC, and the motion image detection is used as an image of the dynamic image file. For example, the IC for the LCD is used to transmit a dynamic image file (such as a video file) to the IC to be tested. Since the dynamic image file has dozens of continuous moving image data, the detecting device It is detected whether the complete continuous motion image data output by the IC can be smoothly presented without residual image to judge the quality of the IC.

Please refer to FIG. 1 , which is an early artificial motion image detection method, which is provided with a play end 11 (such as a DVD) to play a dynamic image file, and a test device 12 connected to the play end 11 is inserted into the IC 13 to be tested. And receiving the dynamic image data transmitted by the playing end 11, and then outputting the moving image data to the screen 14, manually viewing the picture clarity, color difference, smoothness and no residual image on the screen 14 to determine the quality of the IC13; However, the manual must view the output of each IC13 on the screen 14 to judge the advantages and disadvantages of the IC13. When the number of IC13 tests is large, it will be labor-intensive and reduce the production efficiency, and the artificial system will judge by its own experience. Ensure that the quality of the test is uniform. In addition, artificially watching the screen 14 for a long time is prone to eye fatigue and discomfort, which affects the quality of the test.

Transfer to the microprocessor 242, the microprocessor 242 reads the standard dynamic image data built in the database 243, and compares the standard dynamic image data with the dynamic image data to be compared, and then compares the results. To the display device 25 for discriminating the advantages and disadvantages of the IC; however, the capture card 241 of the computer 24 is not dedicated to testing, and the number of dynamic image data that can be captured per second is limited (eg, 7 moving image data per second) When the playback terminal 21 outputs more than 30 pieces of motion picture data per second, but the capture card 241 only randomly captures 7 pieces of motion picture data per second, which causes the other 23 pieces of motion picture data to be lost, so that the play end 21 Must constantly The dynamic image data is overwritten, and the capture card 241 is randomly selected, so that the detection operation is quite time consuming and the production efficiency is lowered. Moreover, the computer 24 capture card 241 randomly acquires 7 moving image data, 7 sheets. The motion picture data may be discontinuous motion picture data, and it is impossible to compare whether the motion picture data can be smoothly presented without image sticking, etc., so that a comparison of static image data is formed, which is not a comparison of continuous motion picture data, so This detection device cannot compare the complete continuous motion image data of the entire image file, resulting in the lack of quality of the IC detection.
