METHOOD FOR DISPLAYING AN IMAGE OF POSTER EFFECT IN PORTABLE TERMINAL}

The present invention relates to an image displayed on a portable terminal, and more particularly, to a method of displaying an image of a poster effect.

In general, a portable terminal having a camera can capture an image, and store or display the captured image. However, the captured images cannot be displayed in various ways. Therefore, the present invention proposes a method for displaying a variety of captured images.

SUMMARY OF THE INVENTION An object of the present invention is to provide a method for displaying an image captured by a portable terminal with a poster effect.

According to an aspect of the present invention, there is provided a poster effect of displaying an image photographed by a mobile terminal, the method comprising: previously storing an RGB color table corresponding to color values for each array index; Detecting an AlgiBi color value representing a color from a photographed image, and searching for an array index corresponding to the AlgiBi color value by applying the detected AlgiBi color value to an array index of the AlgiBi color table. And reading the color values corresponding to the retrieved array index from the Algivy color table, and storing and displaying the photographed image according to the read color values. .

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be noted that in the following description, only parts necessary for understanding the operation according to the present invention will be described, and descriptions of other parts will be omitted so as not to distract from the gist of the present invention.

The camera provided in the portable terminal captures an image and includes a camera sensor for converting the captured image into an electrical signal. It is assumed here that the camera sensor is a CCD sensor. In addition, the signal processor of the portable terminal converts the video signal input from the camera into an image signal. The signal processor may be implemented by a digital signal processor (DSP). The image processor of the portable terminal transmits the image signal output from the signal processor to the display unit of the portable terminal. At this time, the display unit of the portable terminal displays the image signal.

1 is a flowchart for displaying an image of a poster effect in a portable terminal according to an embodiment of the present invention. 2 is a view showing a color table that can simplify the color according to an embodiment of the present invention. With reference to FIG. 1 and FIG. 2, how to display a poster effect using a captured image of a mobile terminal.

In step 101, the controller of the portable terminal detects and reads a red green blue (RGB) color value from an image input from a camera or an image stored in a memory. In this case, the RGB signal is a color signal, and signals red, green, and blue, which are three primary colors of light, are transmitted, and the display unit of the portable terminal reproduces an image based on the signal. The RGB model can represent various colors when the color image is reproduced by using a false color scheme in which a ratio of red, green, and blue is mixed to create a desired color.

In step 103, the controller applies the read RGB color value to the array index of the color table to retrieve the array index corresponding to the RGB color value. The color table is stored in the memory as a table for simplifying the color of the image, and color values correspond to each array index. Referring to FIG. 2, each of the RGB color tables has 32 color values, R color 64, and B color 32. Here, the incremental numbers in odd columns are defined as the array index of the color table, and those in even columns are defined as the color values of the color table. The RGB color value is applied to the array index of the color table. That is, the array index of the color table corresponding to the RGB color value is found. 2 illustrates the following program.

byte color_g [] = {0, 4, 4, 4, 8, 8, 8, 8, 12, 12, 12, 12, 16, 16, 16, 16, 18, 18, 18, 18, 24, 24, 24, 24, 28, 28, 28, 32, 32, 32, 32, 32, 36, 36, 36, 36, 40, 40, 40, 40, 44, 44, 44, 44, 48, 48, 48, 48, 52, 52, 52, 52, 56, 56, 56, 56, 58, 58, 58, 58, 63, 63, 63, 63};

byte color_r [] = {0, 4, 4, 4, 8, 8, 8, 8, 12, 12, 12, 12, 16, 16, 16, 16, 18, 18, 18, 18, 24, 24, 24, 24, 28, 28, 28, 28, 31, 31, 31, 31};

byte color_b [] = {0, 4, 4, 4, 8, 8, 8, 8, 12, 12, 12, 12, 16, 16, 16, 16, 18, 18, 18, 18, 24, 24, 24, 24, 28, 28, 28, 28, 31, 31, 31, 31};

In step 105, the controller reads color values of the color table corresponding to the array index of the color table. In step 106, the controller reads the color values of the color table corresponding to the color table array index. For example, assuming that R = 14, G = 3, and B = 18 in the RGB color values read from the original image, the array index of the color table corresponding to the RGB color values is also R = 14, G = 3, B = 18. At this time, the color values of the color table are R = 16, G = 4 and B = 18.

In step 107, the controller determines whether to enhance the poster effect. In other words, it is determined whether there is a poster effect emphasis request for the captured image. The controller proceeds to step 109 unless the poster effect is stronger (ie, no poster effect emphasis request). The control unit also repeats step 105 if the poster effect is stronger (that is, if there is a poster effect emphasis request). As the controller repeats the step 105, the color simplification will be further progressed. For example, the RGB color values in the first image were R = 14, G = 3, B = 18, where the color values in the color table were R = 16, G = 4 and B = 18. If the controller repeats step 105, the array index of the color table corresponding to the color value of the color table is R = 16, G = 4, B = 18. At this time, the color values of the color table repeatedly read are R = 18, G = 8, and B = 18. That is, it can be seen that the color is simplified as the step 105 is repeated. Therefore, the poster effect can be obtained. In step 109, the controller stores an image as a color value of the read color table or displays the image on the display unit of the portable terminal.

3 is a view showing an image of a poster effect that can be displayed in a portable terminal according to an embodiment of the present invention. Referring to FIG. 3, a generally displayed image is the same as an original photograph, and an image showing a poster effect may be displayed when the above-described process of FIG. 1 is performed. In particular, the control unit may be displayed as weak, standard, or strong as shown in FIG. 3 by repeating step 105.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the scope of the following claims, but also by the equivalents of the claims.

The present invention as described above, by displaying the image photographed in the portable terminal with a poster effect, the user has the advantage that you can feel the interest while making a variety of images.
