The electronic device includes a picture quality processor. The image quality processor is a processor that processes the image quality of image frames. The image processor may be a PQ (Picture Quality/image Quality) Chip or an SOC (System-On-Chip) Chip. The target image frame is an image frame subjected to image quality processing.
The electronic equipment acquires an original image frame sent by a connected television, sends the original image frame to the image quality processor, and controls the image quality processor to perform image quality processing on the original image frame to obtain a target image frame.
It can be understood that the image definition of the target image frame after the image quality processing is higher than that of the original image frame, the color fidelity rate of the target image frame after the image quality processing is higher than that of the original image frame, and the playing fluency of the video formed by the target image frames after the image quality processing is higher than that of the video formed by the original image frames.
The higher the picture definition, the more detail the image frame shows, the more detail the target image frame can show, and the more refined the shown detail. The higher the color fidelity ratio, the closer the picture displayed by the image frame is to the actual scene, and the closer the picture displayed by the target image frame is to the actual scene.
