Embodiment Construction

[0043] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0044] In the present invention, in order to make the image clearer and more gorgeous, the image conversion should be carried out according to the formula 1.

[0045] [mathematical formula 1]

[0046] Out(x,y)={MAX-[(MAX-In_1(x,y))×(MAX-In_2(x,y))]÷MAX}

[0047] Here, In_1(x, y) represents the pixel brightness value in the x and y coordinates of the input image 1, In_2(x, y) represents the pixel brightness value in the x and y coordinates of the input image 2, MAX Represents the maximum brightness value owned by the pixel, and Out(x, y) represents the pixel brightness value of the converted image on the x and y coordinates.

[0048] In the present invention, the process of converting two images as shown in the above formula 1 is named screen merge.

[0049] When converting images by screen me...

Abstract

The present invention relates to an image conversion method and a device thereof capable of displaying images more clearly and gorgeously. Through the image conversion method of the present invention, the image taken from the camera and the same layer image as the image can be screen merged. At this time, the layer image should at least complete one or more operations of contrast enhance, saturation enhance or smoothing before screen merging. In addition, the present invention can also use the star photo effect to depict different characters according to different backgrounds.

Description

【Technical field】 [0001] The present invention relates to the technology of an image processing device, in particular to the technology of image conversion method and device for performing screen merging processing on captured images to provide a clearer image quality and gorgeous effect. 【Background technique】 [0002] Currently, digital cameras that support high-quality images and can perform various image editing are widely used. Based on this, recently, products that function as digital cameras by attaching cameras to mobile communication terminals such as mobile phones and PDAs with excellent mobility have been launched. [0003] Generally speaking, a dedicated digital camera can provide high-quality images, and the captured images are mainly converted on a computer to obtain clear and high-quality images required by users. [0004] On the contrary, it is difficult to capture high-quality images with cameras installed on terminals such as mobile phones due to the chara...
