Description

Mobile communication system and method for selecting and transmitting color image}

The present invention relates to a mobile communication system and method for color image selection and transmission, and more particularly, to a mobile communication system and method in which a sender can arbitrarily select a color and transmit a desired color image.

In general, the mobile communication terminal is mainly used to perform wireless communication with the other party, but recently, various additional services are provided through the mobile communication terminal due to the development of communication technology. The information provided by such an additional service is mainly managed by a communication server providing a mobile communication service, but as the storage space of the mobile communication terminal increases, simple image information may be stored in a memory of the mobile communication terminal.

Thus, a conventional method of selecting and transmitting image information stored in a memory of a mobile communication terminal will be described with reference to FIG. 1.

Referring to FIG. 1, first, when a user presses a menu key of a mobile communication terminal to select image information stored in the mobile communication terminal (S101), the mobile communication terminal displays text images as shown in FIG. 2A on the LCD screen. (S102).

When the text images are displayed in this way, when the user presses a key and selects an image of "pretty face" of item 1 (S103), the mobile communication terminal transmits the selected image on the LCD screen as shown in FIG. 2B. A screen for querying is displayed (S104).

Subsequently, the mobile communication terminal determines whether there is a user's request for transmission of the selected image (S105), and if there is no request for transmission, maintains the display state of the screen as shown in FIG. 2B.

If there is a transmission request, the mobile communication terminal transmits the selected image to the counterpart (S106).

However, in the conventional image selection and transmission method as described above, since the image is transmitted only in black and white color, it has not been able to meet the desire of consumers who want various color images in recent years.

In order to meet such consumer needs, a color image is provided through a WAP server connected to a wireless communication network. However, in the conventional mobile communication system, a color image transmission method is used to receive a color image of a mobile communication terminal on a receiving side. Regardless of the specification, the color image set in the highest image specification of the sending mobile terminal is transmitted to the swap server, so it takes a lot of time or is difficult to transmit the color image to the receiving mobile terminal of which the specification is inappropriate. There was a problem that was not made.

In addition, when transmitting a color image in the conventional mobile communication system, since a large usage fee is imposed when transmitting a color image or uploading an image, there is a problem that consumers avoid using a color image transmission service.

Accordingly, the present invention has been made to solve the above problems, the sender selects a color randomly and transmits a desired color image, thereby selecting and transmitting a color image that can satisfy various needs of consumers for communication services. The purpose of the present invention is to provide a mobile communication system and method.

The present invention converts an image of a color selected by a sender into an image of a color that meets the specifications of a mobile communication terminal on the receiving side, and transmits the color image to select and transmit a color image that can significantly increase the transmission speed of the color image. Another object is to provide a communication system and method.

After confirming the specification and confirming that the second mobile communication terminal 320 can receive the "16 color" image, the swap server 340 moves the "16 color" image to the second through the wireless communication network 330. Transmit to communication terminal 320.

If it is confirmed that the second mobile communication terminal 320 cannot receive the "16 color" image and only the "4 gray" image and the "black and white" image, the swap server 340 requests the " 16 color " image is converted into a " four gray " image that can be received by the second mobile communication terminal 320 of the receiver, and then the " four gray " image is transmitted through the wireless communication network 330. To 320).

If the check result indicates that the second mobile communication terminal 320 is capable of receiving only a "monochrome" image, the swap server 340 transmits the "16 color" image requested by the sender to the second mobile communication terminal 320 of the receiver. ) Converts the image into a " monochrome " image that can be received, and then transmits the " monochrome " image to the second mobile communication terminal 320 through the wireless communication network 330.

As a third example, when the sender transmits a "256 color" image to the receiver's second mobile communication terminal 320 through the first mobile communication terminal 310, the swap server 340 is configured to display the second mobile communication terminal 320. Checking the specification, if the second mobile communication terminal 320 is determined to be able to receive the "256 color" image, the swap server 340 is moved to the second "256 color" image through the wireless communication network 330 Transmit to communication terminal 320.

If the second mobile communication terminal 320 can not receive a "256 color" image and can only receive a "16 color" image, a "4 gray" image, and a "monochrome" image, the swap server 340. Converts the " 256 color " image requested by the sender to a " 16 color " image that can be received by the second mobile communication terminal 320 of the receiver, and then converts the " 16 color " Transmit to the second mobile communication terminal 320.

If the second mobile communication terminal 320 can receive only the "4 gray" image and the "black and white" image as a result of the check, then the swap server 340 displays the "256 color" image requested by the sender. 2 The mobile terminal 320 converts the image into a "4 gray" image that can be received, and then transmits the "4 gray" image to the second mobile terminal 320 through the wireless communication network 330.

In addition, if the second mobile communication terminal 320 is a specification that can only receive a "black and white" image, the swap server 340 receives the "256 color" image requested by the sender of the second mobile communication terminal 320 ) Converts the image into a " monochrome " image that can be received, and then transmits the " monochrome " image to the second mobile communication terminal 320 through the wireless communication network 330.
