Abstract

The present invention discloses an image processing device and a method for an image display device. Watching burden caused by fragmentized image can be reduced by not displaying image mute state but displaying the prior still image or not displaying fragmentized image block caused by compressing the image which results in bad receiving but displaying the image of the prior block, when converting the channels or the input signals in order not to display a momentary no-signal state. A temporary still phenomenon of the image can be prevented by an still image of the prior image and a bland transition image can be provided by a multi-image converting technology when the audience converts images. Even though fragmentized image block caused by compressing the image which results in bad transmitting or receiving, the prior image can be diaplayed faithfully, therefor minimizing the watching burden of the audience.

Description

1. Technical field [0001] The present invention relates to an image display device, in particular to a device that displays the previous screen by not displaying the state of image mute (mute) in order not to display the momentary no-signal state when channel switching or input signal switching is about to be performed. A still image, or an image processing device and method for an image display device that does not display fragmentation of image blocks caused by poor reception of compressed images, but displays images of previous blocks, thereby reducing viewing burden caused by image fragmentation. 2. Background technology [0002] Generally speaking, the image display device includes a representative TV, which selects and demodulates the broadcast signal of the channel selected by the user from the broadcast signal transmitted by the TV station, separates it into sound and image, and then passes through the related sound An image display device that outputs images through...
