The present invention is to adjust the color tone of the digital image signal taken by the mobile terminal, in particular, the image tone adjusting device of the mobile terminal for manually adjusting the color tone through the infant (UI) while the user directly checks the captured image with the display unit And to a method.

The mobile terminal (UE: USER EQUIPMENT) freely moves in the service area (SERVICE AREA) formed by the corresponding base station (RAN: RADIO ACCESS NETWORK) of the registered mobile communication system and monitors and monitors the mobile switching center (MSC). It is a high-tech wireless communication device that allows an individual to carry it anywhere while always carrying it directly by wirelessly connecting and communicating with a desired party anytime and anywhere through a communication path established by control and switching.

The mobile terminal (UE) generally has a low utilization rate because the time used for communication is relatively small and the time for waiting or carrying for communication is increased.

As described above, in order to increase the low utilization rate of the mobile terminal (UE), to improve the applicability and convenience of the real life, and to promote the communication use, various additional services have been developed and provided.

The additional service is provided in addition to the basic mobile communication service of the mobile terminal, and is an additional service developed and provided by a mobile communication service provider and an additional function developed by a producer and provided in a built-in state to a mobile terminal (hereinafter referred to as additional service). Service).

Additional services developed and provided by the producers include cameras, Bluetooth, wireless LAN, radio, games, electronic calculators, calendars, clocks, ringer settings, etc. The mobile communication service providers provide text messages and video. There are messages, online games, wireless Internet access, and so on, but there are many different kinds as above, but new functions are being developed and added.

The demand for a camera phone with a digital camera function added to the portable terminal is gradually increasing. Accordingly, corresponding additional services for applying a digital video signal captured by the digital camera are also gradually increasing.

In particular, a digital video signal or a photo signal photographed by the camera of the portable terminal differs in color or color tone, white balance, exposure, brightness, etc. due to ambient lighting, and is used for editing to control the video signal. There was an uncomfortable problem of using the device or the like.

Accordingly, there is a need to develop a technique for manually editing and adjusting color tone of a digital video signal or a photo signal photographed by a mobile terminal.

Hereinafter, a color tone adjusting method of a mobile terminal according to the prior art will be described with reference to the accompanying drawings.

Attached to explain the prior art, Figure 1 is a functional configuration of the color tone adjusting device of the mobile terminal according to the prior art, Figure 2 is a flow chart of the color tone adjustment method of the mobile terminal according to the prior art.

Referring to FIG. 1, the color tone adjusting device of the portable terminal according to the related art is described. When the image signal of the subject is to be captured, the photographing element (CCD; CHARGE COUPLED DEVICE) is controlled by the control unit 20. The photographing unit 10 provided photographs the subject and outputs an image signal.

The control unit 20 applies the digital image signal output from the photographing unit 10 to the automatic color tone unit 50 to automatically adjust the color tone (HUE), so that the combination of red green blue (RGB: RED GREEN BLUE) is constant. Do it.

The need for the hue adjustment is that the video signal to be photographed is different from the original hue due to illumination around the subject, that is, since the combination of the red cyan color is taken differently from the original hue, It is to restore the hue difference to the original hue.

As described above, the image signal digitally photographed by the photographing unit 10 and the color tone adjusted by the automatic color tone unit 50 is recorded and stored in a corresponding storage unit provided in the controller 20, and the input / output unit ( The output is displayed through the display unit 40 and is wirelessly transmitted to the designated counterpart by being applied to the wireless unit 30.

However, the color tone adjustment according to the prior art of the above configuration has a limitation of automatic control, and there is a problem that white balance and luminance cannot be adjusted.

As described above, the image signal in which the digital signal processing (DSP) is automatically performed is applied to the control unit 110 in a matching state by the matching unit 108, and the control unit 110 is the infant unit 150. Output to the display unit 160 through the visual confirmation of the video signal.

The digital image signal output to the display unit 160 is digital signal processing (DSP) by the DS skin 106 of the camera unit 100, and is corrected to some extent, but the user manually adds a color tone (HUE) for confirmation. It may be necessary to adjust, and when the corresponding control command for adjusting the color tone (HUE) is applied to the control unit 110 through the input / output unit 140 as described above, the control unit 110 controls the manual tone unit 130. To output the control window for manual color tone adjustment.

The manual color tone control window output from the manual color tone unit 130 is applied to the infant unit 150 and is displayed on a part of the display unit 160 in a user interface (UI: USER INTERFACE) state, so that the red and green RGB) Manually check the hue adjustment, and manually adjust it to the desired hue (HUE).

The color tone adjustment displayed on the control window is manually adjusted for each of red (R: RED), green (G: GREEN), and blue (B: BLUE) by the direction key button input signal provided in the input / output unit 140. The video signal of which the color tone is manually adjusted is recorded and stored in the corresponding area of the controller 110 and wirelessly transmitted to the designated counterpart.

Therefore, the present invention having the above-described configuration has an advantage of easily and quickly adjusting the color tone of the video signal photographed by the mobile terminal itself.

Hereinafter, with reference to the accompanying Figure 5 will be described a method of adjusting the image tone of the mobile terminal according to the present invention.
