## Abstract

An image display method for handling a dynamic image signal including a plurality of continuous video frames, wherein the method includes steps as follows: Firstly, a first display parameter is output to display an Nth video frame of the plurality of continuous video frames according to a first attribute data of the Nth video frame. Then, at least one of (N+K)th video frame is detected, and when the at least one of the (N+K)th video frame has second attribute data, the first display parameter is output to display the at least one of the (N+K)th video frames. Subsequently, an (N+K+1)th video frame is detected, and when the (N+K+1)th video frame has the second attribute data, a second display parameter is output to display the (N+K+1)th video frame according to the second attribute data. Wherein, K is a positive integer greater than 1.
