The present invention provides a control method, a control device, and a display device for image card detection. The control method includes: detecting the actual area of a target pattern on an image frame; comparing the detected actual area of the target pattern with a first threshold comparing; when the actual area of the target pattern matches the first threshold, comparing the actual area of the target pattern on the detected image frame with a second threshold, where the second threshold is greater than the first threshold; The image card detection function is enabled according to the comparison result between the actual area of the target pattern on the detected image frame and the second threshold. The actual area of the target pattern on the detected image frame is compared with the first threshold and the second threshold to enable the image card detection function, so as to avoid frequent switching of the image card detection function on or off, and avoid screen flickering problem, improve the display effect.
Description
technical field [0001] The invention relates to the field of display, in particular to a control method and control device for image card detection, and a display device. Background technique [0002] In the application process of MNT products, in some special images, there may be problems such as serial number interference, which needs to be solved by turning on the Pattern Detect Function (PDF) to change the data polarity, and the PDF may be turned on or off. , resulting in frequent and constant switching of PDF opening or closing, which in turn causes screen flickering and affects the display effect. SUMMARY OF THE INVENTION [0003] In view of this, the present invention provides a control method, a control device and a display device for image card detection, which are used to solve the problem of screen flicker caused by frequent opening or closing of image card detection. [0004] In order to solve the above-mentioned technical problems, the present invention adopt...
