1 is a diagram illustrating a configuration of a mobile communication terminal according to an embodiment of the present invention. Herein, the mobile communication terminal may be a mobile telephone.

Referring to FIG. 1, a mobile communication terminal includes a tuner 50, a decoder 60, an image processor 70, and a display 80 to receive a television broadcast signal. In addition, an RF unit 21, a data processor 23, an audio processor 25, a controller 10, and a keypad 27 are provided to perform a call and data transmission / reception function, which are basic functions of a mobile communication terminal.

Meanwhile, the antenna connected to the tuner 50 for receiving the television broadcast signal illustrated in FIG. 1 and the antenna connected to the RF unit 21 for the call function may be implemented as a single antenna. Two antennas are shown.

According to the present invention, the television broadcast signal received through the antenna and the tuner 50 is displayed on the display unit 80 and at the same time it is possible to capture the displayed video image and transmit it by the blocks for the call and data transmission and reception functions. . That is, the multitasking as described above is possible because the television mode for receiving the television broadcast signal and the call mode for performing call and data transmission and reception can be simultaneously processed by the respective functional blocks. In addition, since the two modes are controlled by the image processing unit in the controller 10 to be described later, the television image can be received and displayed in real time even during capturing, recording, and transmitting the television image.

Hereinafter, the structure of the transmission apparatus according to the present invention shown in FIG. 1 will be described in more detail.

The RF unit 21 performs wireless communication of the mobile communication terminal. The RF unit 21 includes an RF transmitter for upconverting and amplifying a frequency of a transmitted signal, and an RF receiver for low noise amplifying and downconverting a received signal. The data processor 23 includes a transmitter for encoding and modulating the transmitted signal and a receiver for demodulating and decoding the received signal. That is, the data processor 23 may be configured of a modem and a codec CODDEC. The television image captured by the data processor 23 is coded and transmitted through the RF21.

The audio processor 25 plays a function of reproducing a received audio signal output from the data processor 23 or transmitting a transmission audio signal generated from a microphone to the data processor 23. The audio processor 25 also plays a function of reproducing the audio signal of the television signal output from the decoder 60 which will be described later in the television mode.

The keypad 27 has keys for inputting numeric and text information and function keys for setting various functions. In addition, the keypad 27 includes various mode setting keys for capturing, transmitting, and storing a television video signal displayed according to an exemplary embodiment of the present invention. In particular, when capturing a moving image, a mode setting for performing a capture start command and a capture end command is added.

The memory 29 may be composed of program memory and data memories. The program memory may store programs for controlling a general operation of the portable telephone and programs for processing a television video signal according to an embodiment of the present invention. In addition, the data memory 29 temporarily stores data generated during the execution of the programs.

That is, the still image or moving image captured in accordance with the present invention is temporarily or permanently stored in the data memory 29.

Meanwhile, the image processing unit 70 constructs a moving image according to the received television signal in frame units and temporarily stores the moving image image in its own memory and transmits the image to the display unit 80. Also, data stored in the previous frame is read and output to the display unit, and data of the current frame is stored. Accordingly, since every frame data is stored and read in real time in a memory separately provided in the image processor 70, a memory 29 connected to the controller may be used as a memory for storing the frame data.

If a still image is transmitted according to an exemplary embodiment of the present invention, the data of one frame may be directly transmitted in real time in the image processor 70 without being separately stored in the memory 29. More detailed processing contents of the image processor 70 will be described later with reference to FIGS. 2 and 3.

The controller 10 performs a function of controlling the overall operation of the mobile communication terminal. In addition, the controller 10 may include the data processor 23. The control unit 10 captures and transmits the image simultaneously with the display of the television image when a capture and transmission command is received from the keypad 27 while displaying a television image (ie, a television mode) according to an embodiment of the present invention. That is, the call mode).

In the television mode, the controller 10 controls the image processor 70 to display a television image signal received according to the set television mode, and outputs user data in the television mode to the image processor 70. In the communication mode, the controller 10 controls the image processing unit 70 to operate in a television mode or an on screen display (hereinafter referred to as an 'OSD') mode, and outputs user data in the communication mode to 70. do. When the voice communication mode is performed in the communication mode, the controller 10 controls to perform a voice communication by blocking a path of the television audio signal output to the decoder 60 which will be described later.

The tuner 50 receives a television video signal of a selected channel under the control of the controller 10 and performs a function of frequency converting the received television video signal. The decoder 60 demodulates and decodes the composite video signal of the television output from the tuner 50. The decoder 60 separates the audio and video signals from the composite video signal, decodes the separated audio signal and the video signal, applies the audio signal to the audio processor 25, and transmits the video signal to the video processor 70. The decoder 60 decodes the television video signal and outputs color signal R, G, and B and a synchronization signal (a horizontal synchronization signal and a vertical synchronization signal).

The image processing unit 70 communicates data with the control unit 10, and a signal processing function for displaying the user data output from the control unit 10 and the television video signal output from the decoder 60 according to the television mode and communication mode control of the control unit 10. Do this. The image processor 70 processes a video signal output from the decoder 60 and user data output from the controller 10 and outputs the image signal to a corresponding area of the display unit 80 in the television mode.

In this case, the user data includes a current time, battery level indication, reception sensitivity, and the like, and also means status data according to a state change of the television mode. The image processor 70 processes and outputs the television signal in a frame size, and outputs the television image data and the user data separately. In addition, the image processor 70 may provide communication service in a television mode or an OSD mode in a communication mode.

That is, when the communication mode is performed in the television mode, the image processor 70 outputs television image data and outputs user data in the communication mode output from the controller 10. In addition, when the communication mode is performed in the OSD mode, the image processing unit 70 blocks the television image data and controls to display user data in the communication mode output from the control unit 10. In this case, the user data may be a text message or subscriber information.

The display unit 80 displays data output from the control unit 10 in a communication mode, and displays television image data and user data output from the image processing unit 70 in a corresponding area in the television mode. In the television mode, the display unit 80 displays the television image signal output from the image processing unit 70 in the first display area, and displays the user data in the second display area.

In addition, the display unit 80 may further include a third display area, wherein the third display area may be used as an area for displaying a soft key such as a menu. In the communication mode, the display unit 80 displays a television video signal in the first display area in the television mode, displays user data in the communication mode in the second display area, and communicates in the first and second display areas in the OSD mode. Display user data in mode.

The display unit 80 may use an LCD. In this case, the display unit 80 may include an LCD controller, a memory capable of storing image data, and an LCD display device. In this case, when the LCD is implemented by using a touch screen method, the keypad 27 and the LCD may be input units.

FIG. 2 is a diagram illustrating a television receiver configuration among the components of FIG. 1.

Referring to FIG. 2, the operation of the television mode of the mobile communication terminal is performed. When the user selects the television mode, the controller 10 notifies the image processor 70. The image processor 70 then outputs control data for selecting a channel to the tuner 50 and drives the decoder 60. Then, the tuner 50 is tuned to a channel corresponding to the channel control data output from the image processor 70, and receives and frequency-converts the television video signal received through the tuned channel and outputs the same to the decoder 60.

The decoder 60 decodes the received television video signal and outputs an RGB analog video signal and a synchronization signal (horizontal and vertical synchronization signals). The decoder 60 separates and outputs color signals from the received composite video signal. The decoder 60 may be an NTSC decoder.

The image processor 70, which receives the RGB image signal and the synchronization signals output from the decoder 60, adds user data to the television video signal and displays it on the display 80. In this case, the user data may be user data output from the controller 10. The user data may be generated by the image processor 70 under the control of the controller 10. The user data are displayed on the television video signal in on-screen form (ie OSD).

The image processing unit 70 inputs an RGB analog television video signal, converts the analog video signal into digital data by an analog-to-digital converter (A / D converter) having the analog video signal, and outputs the digital data to the display unit 80. In addition, the image processor 70 may display user data output from the controller 10 or user data generated therein under the control of the controller 10 by using an OSD, and a capture function of the displayed television screen and a block of the OSD It has a copy function.

When the capture command is input in the television mode as described above, the controller 10 notifies the image processor 70 of the capture command. At this time, the image processing unit 70 displays the received television video signal on the first display area of the display unit 80 and displays a menu related to the capture command on the second display area. In addition, when the television video signal is enlarged and displayed in the first and second display areas of the display unit 80, the image processor 70 displays the television video signal in the first display area in a reduced manner, and the menu associated with the capture command is displayed. Is displayed in the second display area.

In addition, the image captured according to the capture command is stored in the memory 29 from the image processor 70 under the control of the controller 10.

3 illustrates a detailed block configuration of the image processor 70 of FIGS. 1 and 2, and FIG. 4 illustrates a data access timing between the controller 10 and the image processor 70.

Referring to FIGS. 3 and 4, the operation of the image processor 70 will be described. The A / D converter 111 may digitally convert the RGB analog signal output from the decoder 60. Here, it is assumed that the A / D converter 111 converts the RGB analog signal into 18-bit RGB digital data (65536 colors).

A scaler 113 inputs the RGB digital data output from the A / D converter 111 and the horizontal synchronizing signal HSYNC and the vertical synchronizing signal VSYNC output from the decoder 60, and converts the RGB digital data based on the synchronization signals. Scale the size. The scaling operation is as follows. First, determine the display image size. Secondly, the size VXSIZE and VYSIZE are set for each of the horizontal and vertical positions of the determined display image size.

In an embodiment of the present invention, it is assumed that the television video signal is scaled from a maximum of 220 * 176 pixels to at least 100 * 75 pixels. Third, set the scaling factor (zoom factor). Fourth, in the horizontal direction, 720 * 4096 / VXSIZE is calculated and set to HLSR, and in the vertical direction, 240 * 2048 / VYSIZE is calculated and set to VLSR. In an embodiment of the present invention, it is assumed that an input video signal is scaled up to 220 * 176 pixels. The scaler 113 converts the RGB 18-bit data into RGB 16-bit data. Here, the 16-bit data [15: 0] is 5 bits of R (Red) data [15:11], 6 bits of G (Green) data [10: 5] and 5 bits of B (Blue) data [ 4: 0].

The memories 131, 133, and 135 are memories for storing data having a frame size (176 * 220 * 12 bits). In the television mode, the memory 131 is used as a memory for storing user data, and the memories 133 and 135 are used as a memory for storing image data. In the OSD mode, the memories 131 and 133 are used as a memory for storing user data, and the memory 135 is used as a memory for storing background screen data.

The memory controller 123 performs a function of controlling access to the memories 131, 133, and 135 under the control of the controller 10. The memory 123 separately controls the memories 131, 133, and 135 according to a television mode and an OSD mode. First, in the television mode, the memory controller 123 accesses the user data output from the controller 10 to the first memory 131, and the current frame image data output from the scaler 113 from the second memory 133 (or the third memory 135). And stores the previous frame image data stored in the third memory 135 (or the second memory 133).

The memory controller 123 stores and outputs RGB image data of the television received in the memories 133 and 135 in units of frames. In this case, when the current frame image data is stored in the memory 133, the image data of the previous frame stored in the memory 135 is output, and when the image data of the current frame is stored in the memory 135, the image of the previous frame stored in the memory 133 Print the data. That is, the memory controller 123 processes the television video signal in real time by storing the frame data received when the memories 133 and 135 are accessed and outputting the previous frame data stored therein.

In other words, when displaying a television video signal, 30 frames per second must be processed, and thus the video signal is transmitted to the display unit 80 in real time using two frame memories. In addition, the memory controller 123 outputs the frame image data to the display unit 80 during a frame period (vertical synchronization signal period), and outputs user data stored in the memory 131 in the idle period before the next frame starts. Therefore, the memory controller 123 outputs the frame image data stored in the memory 133 or 135 in the section in which the video signal exists in the section displaying the video signal of one frame and in the memory 131 in the idle section. Output the stored user data.

Secondly, in the OSD mode, the memory controller 123 uses the memory 131 and 133 as a memory for accessing user data, and the memory 135 serves as a memory for storing background data. In this case, only one memory 131 and 133 may be set and used instead of the same.

The on-screen data mixer 125 mixes the image data of the frame size and the user data output from the memory controller 123 into on-screen data and outputs the on-screen data to the display unit 80. The timing controller 121 generates a synchronization signal (a horizontal synchronization signal HSYNC, a vertical synchronization signal VSYNC) and a pixel clock DOTCLK detected in the television mode. The timing controller 121 controls the display unit 80 to be synchronized with the pixel, line image data, and frame image data of the image data output from the OSD mixer 125.

The control interface 117 interfaces user data and mode control data between the controller 10 and the image processor 70. In the embodiment of the present invention, the control interface 117 interfaces the control unit 10 with an address of 17 bits and data of 16 bits. At this time, when the most significant bit A16 of the address is 1, the frame memory of the image processor 70 is accessed, and when it is 0, the register of the image processor 70 is accessed.

Referring to FIG. 4, when the controller 10 outputs data to the image processor 70, the controller 10 selects the image processor 70 as shown in 211 and activates the recording mode as shown in 213. As shown in 217, the address MA [16: 0] and the user data MD [15: 0] are output to record the user data in the image processor 70. In this case, the user data may be data such as a current time, remaining battery power, reception sensitivity strength, control data for setting a television screen control and mode, menu data, and the like.

Second, when the controller 10 accesses data from the image processor 70, the controller selects the image processor 70 as shown in 221 and activates the read mode as shown in 225. As shown in 217, the address MA [16: 0] is output to access the user data MD [15: 0] of the address. The control interface 117 functions to interface the output of the controller 10 to be processed by the image processor 70 as shown in FIG. 4.

I2C interface 115 has an I2C busmaster that can control two slave devices. The I 2 C interface 115 controls the tuner 50 and the decoder 60, and is controlled by the control interface 117.

The OSD RAM block copy accelerator 119 may copy an arbitrary rectangular area of the user data to an arbitrary position. The OSD controller 119 may block copy data of an arbitrary rectangular area to an arbitrary position of an image screen displayed by the control data of the controller 10 output from the control interface 117. The copy function is also possible in memory or between memories. In the television mode, only block copy in the memory 131 is possible. In the OSD mode, block copy between the memory 131, the memory 133, and the memory 131 and 133 is possible.

In addition, in order to implement the present invention, the image processor 70 further includes a file compressor 137 and an image converter 139. The file compressor 137 and the image converter 139 compress or convert the captured image under the control of the memory controller 123.

In more detail, the frame image data converted by the scaler 113 is stored in the memory 131 on a frame basis in real time as described above. When capturing and transmitting the image according to the present invention, the frame image is compressed. The process is necessary. The image compression is performed by the file compression unit 137.

On the other hand, when capturing and transmitting video data, the memory 131 stores and reads images in units of frames. Therefore, the frame data must be accumulated and stored separately. In this case, the accumulated and stored moving image images are compressed by the file compression unit 137.

The file compression unit may compress the captured data into any one format selected from JPEG, BMP, GIF, PIC, TIFF, PDF, and EPS formats when the captured data is still image data. In addition, when the captured data is moving image data, the captured data is compressed in any one format selected from MPEG, ASF, ASX, AVI, DAT, FLI, FLC, MOV, MPEG, MPG, RA, RAM, RM, VOB, and VIV formats. can do.

When the data to be captured and transmitted is still image data, the image converting unit 139 converts the size of the image according to the display standard of the receiving mobile communication terminal. For example, the frame image data is converted into a size of 128 × 112 dots or 128 × 96 dots according to the criteria of the mobile communication network operator.

Meanwhile, the still image data converted by the image converter 139 may be transmitted without compression. For example, when the receiving terminal is a terminal having no function of decompressing image data, the still image data is preferably transmitted without compression.

5 is a diagram illustrating a display area of the display unit 80 of FIG. 1. The display unit 80 has a first display area 81 for displaying a television image received in the television mode and a second display area 83 for displaying user data. The display device may further include a third display area 85 for displaying softkey information for setting a menu in the television mode or the OSD mode. In an embodiment of the present invention, the first display area 81 (or the first display area and the second display area) is used as an area for displaying a television video image, and the third display area is a menu for capturing and transmitting a television image. Use as the displayed area.

6 is a diagram illustrating a configuration example of the keypad 27 and the display unit 80 according to the embodiment of the present invention. In the configuration of the keypad 27, the TV mode ON key 31 is a key for setting the cellular phone to the television mode, and when the TV key is pressed in the standby mode for a long click, the control unit 10 turns the key input to the TV on mode. Detect by key. The TV mode screen size key 33 is a key for changing the size and direction of the screen displayed on the display unit 80. When the TV key is shortly pressed in the state where the television mode is set, the controller 10 Detect key input with screen adjustment keys.

In the exemplary embodiment of the present invention, the TV on and screen adjustments are implemented using one TV key. However, the TV on key and the screen adjustment key may be independently implemented. When the TV mode is set and the television mode is set and the TV screen signal is displayed, the confirmation key or the shooting key is pressed, and the controller 10 detects the key input as the screen shooting key. The menu key 37 performs a function of adjusting a channel, a screen, a timer, etc. while the television mode is set and the TV mode is set.

According to the present invention, when the photographing key or the confirm key is pressed in the television mode, the display proceeds to the capture mode. In the capture mode, a still image or a moving image can be captured according to two embodiments of the present invention. Each detailed function is displayed on the display unit according to the detailed functions according to the embodiments. Detailed functions according to the embodiments will be described later.

7 is a diagram illustrating a procedure for capturing and transmitting a received television signal according to an embodiment of the present invention.

Referring to FIG. 7, first, a television reception mode is set in step 701, and the television reception signal is displayed through the display unit of the mobile communication terminal.

In the state of executing the television mode, in step 703, a shooting menu is displayed. When the screen shooting key is input with reference to the displayed shooting menu, the controller 10 detects this in step 705 and selects a still image and a moving image selection menu. Is displayed.

If the capture menu of the still image in step 709 is selected through the selection menu, the still image currently displayed is captured in step 713. In this case, the displayed image may be stopped at the moment of capturing in order to edit or confirm the captured still image. Alternatively, the television moving image may still be displayed even if the currently displayed image is captured, and the lower menu may be changed to a save or transmit menu to determine that a capture command has been performed.

When the video capture menu is selected through the selection menu, in operation 711, the start and end time of capturing the currently displayed video image may be determined to capture the video image during the time. That is, the user determines the starting point and end point of the capture through the terminal key input while watching the video image being displayed in real time. On the other hand, for simplicity of key input, a time point for selecting a video capture menu from the selection menu may be set as a start point of capturing a video image, and the end point may be additionally determined. In this case, the television image may be displayed on the first display area of the display unit, regardless of the capturing operation.

The captured video image is compressed in step 715. Since the captured video image is considerably larger in file size than general data, it is desirable to compress, store, and transmit the image. As described above, the compression may be performed in any one format selected from MPEG, ASF, ASX, AVI, DAT, FLI, FLC, MOV, MPEG, MPG, RA, RAM, RM, VOB, and VIV formats. Obviously, any other video compression format is applicable to the present invention.

The captured still image or moving image may be transmitted or stored according to the present invention. Meanwhile, the transmission or storage of the image is preferably performed while watching the television image in real time according to the present invention.

That is, the display unit of the mobile communication terminal displays and views a television image through a first display area, and simultaneously transmits the image through another display area (eg, a second display area or a third display area) of the display part. You can perform the save operation.

When the capturing of the still image or the moving image is completed, a storage or transmission menu is displayed on the display unit. When the storage menu of step 717 is selected, the captured data is stored in step 721.

Meanwhile, when the transmission menu of step 719 is selected in accordance with the present invention, a menu for selecting whether to transmit to phone-to-phone or to e-mail is displayed according to the transmission method. If transmission by phone-to-phone in step 723 is selected in the menu, the captured image is transmitted in step 727 according to a general phone-to-phone transmission method.

In addition, if the transmission by the e-mail in step 725 is selected in the menu, in step 729 the captured image is transmitted according to a general e-mail transmission method.

Hereinafter, the transmission methods will be described in more detail. The transmission of the television still image or moving image may be implemented by various methods. On the other hand, the transmission process of the image means the data transmission to the terminal to be transmitted, the processing according to the call mode should be performed, as described above must be performed simultaneously with the television mode.

In addition, the image data may be directly transmitted after the data channel is established with the receiving terminal. The image data may be temporarily stored in the server of the operator and downloaded from the terminal of the receiver according to the request of the receiver.

The method of storing and transmitting to the server of the service provider is as follows. When the image data is transmitted together with the telephone number of the receiving terminal, the image data and the telephone number of the receiving terminal are stored in the server of the operator. The operator informs the receiving side that there is image data to be transmitted from the transmitting terminal. Informing the presence of the received data may be implemented through a short message service (SMS).

On the other hand, the receiving side is notified that there is the image data to be received, and accesses the operator server to download the image data.

Alternatively, a method of transmitting the image data attached to an e-mail is described below. The sender terminal inputs or selects an e-mail address of the receiver through selection of an e-mail transmission menu, and transmits by attaching the image data.

When the image data is attached to an e-mail as described above, the receiver may receive the e-mail message and the attached image data through a mobile communication terminal, and may also receive the image data through a general computer terminal connected online. have.

On the other hand, when transmitting to the phone-to-phone as described above, when transmitting the still picture, it may be different from the display standard of the receiving terminal and the standard of the network operator. Therefore, it should be converted to an appropriate standard (eg, 128 × 112 or 128 × 96 dots) through the image converter 139.

However, in case of sending a file by e-mail, it is not necessary to convert it into a display standard required by a network operator as described above. Therefore, data of its own size (for example, 128 x 160 dots) is compressed as it is (for example, JPEG compression). It is possible. In addition, in the case of transmission by the email, the transmission is performed by performing a process such as a title / content / attachment. On the other hand, the e-mail address of the receiving side can be entered directly or select the stored address through a search depending on the configuration of the menu.
