The present invention relates to an image display, and more particularly, to an image display device that can be conveniently compared when trying to compare a large number of unknowns.

BACKGROUND With the spread of digital cameras and color scanners, digital images are often handled. In the case of such a digital image, the image is processed through a monitor without printing.

1 is a diagram illustrating an example of a method of displaying a conventional image.

(A) of FIG. 1 illustrates a method of arranging an image original on the left side and comparing the modified image on the right side, and (b) of FIG. The figure illustrates how to place images around and compare the entire result on one screen.

The procedure of performing the method of FIG. 1 (a) is as follows. First, place the original image on the left side of the window screen. Then, the image is converted by applying the image conversion value specified by the user. After that, the converted image is displayed on the right side of the window screen.

The procedure of performing the method (b) of FIG. 1 is as follows. First, place the original image in the center of the window screen. Then, the image is converted by applying a specific image conversion value. Then place the converted image around the original image.

However, the problem of such an image display is as follows. First of all, the problem of left and right arrangement is that the original image and the modified image can be compared to be placed next to each other, but the user cannot simultaneously provide a plurality of conversion results. In addition, the problem of the peripheral arrangement is that when there are many converted results, the whole can be compared at a glance, while all the results must be put on the monitor screen, and thus the size of each image becomes smaller, so that it is different from the original image. There is a problem that is difficult to compare.

SUMMARY OF THE INVENTION The present invention has been made in an effort to provide an image display device that can be conveniently compared when a plurality of images are to be compared.

In order to achieve the above object, the image display apparatus according to the present invention, according to the selection of the image through the combo box, the first display unit and the displayed first image and the second display unit for displaying the selected first image and the second image, respectively And a second display unit for displaying a comparison result of the images.

Hereinafter, an image display apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

The first display unit 100 displays the selected first image and the second image, respectively, according to the selection of the image through the combo box. A combo box refers to a combination of a text box and a list box in which a user may directly enter information or select an item from the listed items. Normally it displays a single line item, but clicking on the arrow expands the list so you can select one.

3 is a diagram illustrating an example of an image display screen displayed by the first display unit 100 shown in FIG. 2. As shown in Fig. 3, it is assumed that the original image is a human face, and that a clean face, a bright face, a bright face, a gentle face, a healthy face, and a user-defined face are images for comparison with the original image.

As shown in FIG. 3, when clicking on the combo box of the display screen 200 on the left side with the combo box, a plurality of image lists (original image, clean face, bright face, bright face, gentle face, healthy face and List of faces by user definition) is displayed. When the dual user selects one image, the selected image is displayed as the first image on the display screen 200 on the left side.

Then, if you click on the combo box on the display screen 220 on the right with the combo box, the list of multiple images (original image, clean face, bright face, bright face, gentle face, healthy face and user-defined face) List) is displayed. When the dual user selects one image, the selected image is displayed as the second image on the display screen 220 on the right side.

Meanwhile, the first display unit 100 includes a conversion value input unit 240 for converting an image.

The conversion value input unit 240 is a means for inputting a conversion value for converting the brightness, the saturation or the color of the original image. That is, by adjusting the input bars 242, 244, and 246 shown in FIG. 3, the original image can be converted into an image desired by the user, and the converted image is displayed on the left image display screen 200 or the right image.
