Problems solved by technology

If the scaling ratio does not behave like figure 2 as constant as the panorama of the
[0009] Specifically, in the case of transmitting text by a ticker moving at a constant speed and direction, the enlargement ratio differs between the text displayed on the center area A and the side areas B and C so that the user reads the text difficulty
[0010] Also, since the human eye can sensitively recognize skin tone such as a face, if the face is displayed not in the center area A but in the side areas B and C, the distortion will appear more prominently compared to a general image
In the case of graphics, due to significant changes in brightness or color, it will appear more distorted than normal images

Embodiment Construction

[0046] Exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same elements are indicated with the same reference numerals throughout. In the following description, detailed descriptions of known functions and constructions incorporated herein will be omitted for brevity and clarity.

[0047] Figure 4 is a view illustrating a schematic configuration of an image size conversion device according to an exemplary embodiment of the present invention.

[0048] refer to Figure 4 , the image size conversion device includes an area detector 100 , a scaling ratio adjuster 200 and a scaler 300 .

[0049] The region detector 100 detects fields or frames (F n , F n+1 、...F n+i ; i=integer) to detect message bar area, face area and graphic area. Specifically, the area detector 100 detects an area existing in an input image where the image moves at a constant speed and direction as a message bar ar...

Abstract

The invention provides an image size conversion device and an image size conversion method. The image size conversion device includes: a region detector for detecting a region of interest including a specific image different from a general image from an input image; a scaling ratio adjuster for adjusting the region detected by the region detector. a scaling ratio of the region of interest; and a scaler configured to perform scaling on the input image according to the adjusted scaling ratio. Therefore, it is possible to adjust the scaling ratio according to the characteristics of the input image to display a distortion-free image on the screen.

Description

technical field [0001] Apparatus and methods consistent with the present invention relate to adaptive image resizing, and more particularly, to adaptive image resizing that adjusts an image resizing ratio according to characteristics of image data to display the transformed image on a screen. Background technique [0002] Generally, an image display device such as a television includes an image size conversion function such as 4:3 mode, 16:9 mode, panorama mode, zoom-in 1 mode, and zoom-in 2 mode, and the user can adjust a desired mode to display the transformed image on the screen. image. [0003] figure 1 is a view explaining the configuration of a conventional image size conversion device. [0004] refer to figure 1 , the conventional image size conversion device includes a position detector 10 , a scale ratio (scale ratio) adjuster 12 and a scaler 14 . [0005] The position detector 10 detects about the input frame or field (F n ) information about the position of t...
