Abstract
The invention provides an image detection method, an image detection device, a display panel and a display device. The image detection method comprises the following steps: a flashing image detection step, wherein when a fact that a first row of pixel structures in a first frame are the same as a preset flashing green pixel structure is detected, an odd row of pixel structures in each frame are compared with the first row of pixel structures in the first frame, and when the first row of pixel structures in the first frame are different from the preset flashing green pixel structure, a fact that a flashing image exists is judged. With the method for comparing the odd row of pixel structures when detecting that the first row of pixel structures in the first frame are the same as the preset flashing green pixel structure, the image detection method, the image detection device, the display panel and the display device can distinguish the flashing image from a flashing green image and enable image flashing to be minimized by adjusting voltage of a common electrode when the flashing image is detected, thereby improving a flashing phenomenon.
