Image adjusting apparatus and image adjusting method

Abstract

An image adjusting apparatus and an image adjusting method are disclosed. The image adjusting apparatus includes a first resolution detecting module, a second resolution detecting module, an auto-scaling coefficient generating module, an auto-scaling module, and an image rotation module. The first resolution detecting module detects a first signal of an inputted image inputted by an image inputting apparatus to generate a first horizontal resolution and a first vertical resolution. The second resolution detecting module detects a second signal (i.e., Extended Display Identification Data, EDID) of an image display apparatus to generate a second horizontal resolution and a second vertical resolution. The auto-scaling coefficient generating module generates an auto-scaling coefficient according to the first horizontal resolution, the first vertical resolution, the second horizontal resolution, and the second vertical resolution. The auto-scaling module adjusts the size of the inputted image according to the auto-scaling coefficient.

Description

[0001] This application is a divisional application of the invention patent application with the application number 201110217034.2 and the invention title "Image adjustment device and image adjustment method". Technical field [0002] The present invention is related to image adjustment, and particularly relates to an image adjustment device and an image adjustment method capable of dynamically automatically rotating and zooming images. Background technique [0003] In recent years, with the continuous evolution of technology, image processing technology has also developed quite rapidly. For example, the image scaling function and image rotation function in the image processing technology have been widely used in various image display devices (such as liquid crystal displays, plasma displays, etc.). [0004] As far as the image zoom function is concerned, since the resolution of the image input by the image input device may not be completely consistent with the resolution of the ima...

Problems solved by technology

[0006] Generally speaking, most of the current image adjustment programs are handed over to the display card or central processing unit (CPU) for calculation and output. said that there are still no simple and low-cost solutions available

[0007] Furthermore, current image scalers still have considerable limitations when it comes to image scaling

For example, in addition to the need to fix the resolution of the image display device, the user must also set the image scaling factor in advance for the image scaler to perform image scaling, such as the need described in the conventional patent (Patent No. US7551231B2). Fix the screen resolution and set the zoom factor in advance, that is, the current image resizer still cannot really achieve the function of automatically rotating and zooming the image dynamically
