1. An image display apparatus comprising:
a display;
a remote controller;
a user input interface configured to receive a command from the remote controller; and
a signal processing device configured to, in case in which an image output mode is a first mode, output data of a first image frame and data of a second image frame,
wherein a size of the second image frame is smaller than a size of the first image frame,
wherein the signal processing device is further configured to, in case in which the command corresponds to a second mode, change the image output mode from the first mode to a second mode, and output the first image frame data to the display,
wherein a delay of image output in the second mode is less than a delay of image output in the first mode,
wherein the display comprises:
a timing controller configured to perform signal processing based on an image signal output from the signal processing device; and
a panel configured to display an image based on a signal from the timing controller, and
wherein in case in which the image output mode of the signal processing device is the first mode, the timing controller extracts information regarding the first image frame data based on the second image frame data from the signal processing device, performs signal processing on the first image frame data based on the extracted information, and outputs a signal regarding the processed first image frame data to the panel.
