Abstract

The embodiment of the invention provides a method and device for converting image, and the display system. The image conversion method comprises: detecting character area of image and obtaining detected character area; converting the image according to the character area, obtaining converted image with different aspect ratio with unconverted image. The conversion device comprises a detection unit for detecting character area of image and obtaining detected character area; a conversion unit, converting the image according to the character area and obtaining converted image with different aspect ratio with unconverted image. The embodiment of the invention also provides a display system. The technical scheme of the embodiment can keep the important content area of image and clearly display it.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to an image conversion method, a conversion device and a display system. Background technique [0002] Image conversion in image processing technology generally includes operations such as image scaling. When performing image scaling with different ratios, image distortion is likely to be caused due to inconsistent aspect ratios of the source image and the target image. A typical application scenario is the adaptation of images with an aspect ratio of 4:3 and 16:9. For example, traditional cathode ray tube (CRT, Cathode Ray Tube) TVs basically use a 4:3 image display mode, while the latest High-definition liquid crystal display (LCD, Liquid Crystal Display) TVs all adopt a 16:9 image display mode, so there is a non-proportional resolution conversion problem between 4:3 and 16:9 images. [0003] In image conversion, in general, the human eye is more sensitive to important ...
