Description

Display device and method for color weakness of mobile terminal {A METHOD AND A APPARATUS OF DISPLAYING COLOR FOR COLOUR WEAKNESS WITH MOBILE PHONE}

The present invention relates to the operation of the display unit of the mobile terminal for the color weak, and more particularly, to a display device and a method for the color weakness of the mobile terminal to feel the natural color by correcting and setting the color display color to compensate for the color loss of the color weak will be.

A mobile terminal (MS) is a device that freely moves within a service area of a registered mobile communication system and communicates wirelessly with a counterpart at any time and anywhere, and communicates while being carried and carried by an individual.

The portable terminal has been used to communicate with a mobile communication system by using a voice level signal. However, the portable terminal has been developed into data communication using text and symbols, and is now developing into a multimedia communication including a video signal.

The video signal visually identifies the video signal, and is referred to as multimedia communication because it includes a voice level signal and a text level signal and communicates with a plurality of media. Such a video signal initially includes gray. Although the image was displayed in black and white, it was displayed in color by a combination of three colors of red and green (RGB).

The normal human eye (EYE) can normally distinguish the natural color due to the color, but when an abnormality occurs in the optic nerve of the eye, the ability to distinguish a specific color is inferior, and such a person is called a color weaker, The color weaker must use a separate medical correction device or device to recognize the natural color as normal.

Accordingly, there is a need to develop a display device that allows the color weaker to confirm or recognize the natural color displayed on the color display unit of the mobile terminal without using a separate medical correction mechanism.

Conventional portable terminals do not have a balancing function for adjusting the contrast by the color of the display unit in terms of mechanical, circuit, and software, and the contrast of colors in a computer (PC) or a television (TV: TELEVISION), etc. Balancing function was added.

The human eye has a retina for distinguishing an image, and the retina includes eye cells that distinguish images by stimulation when the images are formed, and the eye cells transmit signal information that is stimulated to the brain. Recognize.

The visual cells are cone cells and rod cells, and the cone cells are distinguished in color and consist of cone cells of red green (RGB: RED GREEN BLUE), and when red is input to the retina, R-cone cells are stimulated. When red is inputted, green is inputted, G-cone cells are stimulated to feel green, and when blue is inputted, B-cone cells are stimulated to feel blue.

Light or color represents all colors by synthesizing the three colors of red cyan (RGB), and the colors are distinguished by the ratio of the R, G, B-cone cells being stimulated.

When the retina is normal, all natural colors are recognized, but when the retina is abnormal, the natural colors are not properly recognized, and the abnormal ones are referred to as color vision abnormalities.

There is a color blindness that does not recognize a specific color significantly above the color vision, and lacks a recognition ability of a specific color.

The color blind patient is caused because there is no one or more types of cone cells among the R, G, B-cone cells, and the color drug is caused by lacking or inferior to the ratio of any one or more types of cone cells, If colors are mixed with other colors, they cannot be distinguished.

Depending on the kind of cone cells, the function of which is weakened, red medicine, green medicine, and blue medicine are classified. In fact, almost all color drug patients are red medicine and green medicine, and blue medicine is very rare.

That is, the red medicine is due to a slight decrease in R-cone cell function, which is a receptor for detecting red (R). For example, only the green (G) portion of a picture or image in which red (R) and green (G) are mixed. On the contrary, the green medicine shows only the red part because the G-cone cell function, which is a receptor for detecting green, is slightly degraded.

However, the red medicine or green medicine as described above, although the function of the cone cells to detect red or green is weak, but only one color of red or green can be distinguished and recognized, for example, If a mixture of red and green is mixed, a person with a weak red color must distinguish between the red and green color by mixing the red more strongly.

In more detail, a person having a normal retinal structure, for example, recognizes a light having a ratio of red cyan (RGB) of 1: 1: 1 as white, while a person having a red drug has a ratio of red cyan 2: 1: 1. Phosphorus light is recognized as white, and in the case of a severe red medicine, light of 3: 1: 1 is recognized as white. Even in the case of the red medicine as described above, red light is recognized when there is only a red light.

The method of correcting the color weaker to recognize the color as a normal person is, for example, in the case of the red medicine, since it transmits a lot of red and blocks a lot of green, it is generally corrected by increasing the contrast of the two colors. It corrects with a colored spectacle lens or a colored contact lens.

Therefore, without the medical correction mechanism or correction tool as described above, color weak people do not recognize or recognize normal colors, and in particular, there is a problem in that the multimedia content displayed on the color display unit of the mobile terminal is not recognized as a normal person.

Therefore, color weak people do not recognize and satisfy the multimedia supplementary service quality of the mobile communication system.

According to the present invention, the color weakness of the color weakness using the multimedia mobile terminal is measured and measured in advance, and the color weakness is corrected and displayed on the display unit of the mobile terminal through the image signal processing, so that the color weakness recognizes the original color of the multimedia supplementary service.
