The charging and communication unit 100 is controlled and monitored by the control unit 130 and automatically supplies charging power when the portable terminal is connected and simultaneously provides a digital data communication path. The charging power is provided from the power supply unit 190, and the controller 130 may control the power supply unit 190 not to supply the charging power to the charging and communication unit 100 by selection. In addition, the charging and communication unit 100 inputs and outputs a digital data signal to be transmitted or received through a data communication path with a connected mobile terminal in a matching state. Accordingly, the controller may automatically search for and copy MP3 music signals, still images, and video signals stored in the portable terminal in an optimal state without errors. Detailed functions of the control unit 130 will be described later.

The touch sensor key unit 110 includes a plurality of direction selection keys and a function key of up, down, left and right, and inputs a signal selected by static electricity. Static electricity is an electrical phenomenon generated by the discharge of accumulated charge as a charging phenomenon generated by the friction of two different objects. In the case of humans, it is common to have friction with clothes and other objects around them so that static electricity is always generated and maintained. If a person touches something in this state, static electricity will discharge to the object. The touch sensor key unit 110 detects such static electricity, inputs it as a selection signal, and transmits the static electricity to the controlling unit.

The memory unit 120 includes a fixed memory provided in an internal electronic circuit of a digital picture frame and an SD memory that is detachably movable. The memory unit 120 is controlled by the control unit 130 and the operation (OPERATION) program, APPLICATION program, operation parameters (PARAMETER), MP3 music signal, video signal, still image signal, calendar information, etc. The data is written (WRITE) and updated (UPDATE) in the area allocated by the control of the controller 130, and the read data is provided (READ) by the search. At this time, the allocation of the area for recording data is designated by the control of the controller 130, and it is preferable to control the MP3 music signal, the video signal, the still image signal, and the calendar information to be recorded in the SD memory. In addition, when an external device such as a computer (PC) is connected to the USB by the control of the controller 130, the SD memory is recognized, and such external device is connected to the SD memory in a state where the connection is allowed. Various data can be recorded, updated and deleted. SD memory is equipped with copyright protection function that monitors the distribution status of stored music files. It is small in size * 24 * 32 * 2.1 mm (mm) in width * height * depth. SD), so it is called SD memory. The comprehensive specification was confirmed by the US Secure Digital Association and is a type of flash memory.

The control unit 130 controls and monitors each functional unit of the entire apparatus and operates by operating the OPERATING program and the application program recorded in the memory unit 120, and monitoring and inputting the touch sensor key unit 110. Display the status of the received signal on the display unit 220, analyzes the selected command to perform the monitoring and charging and communication unit when the mobile terminal is confirmed that connected to the MP3 music signal, the mobile terminal is automatically stored and stored The video signal and the video signal are searched and copied and stored in the designated or allocated area of the memory unit 120.

In addition, the controller 130 sets the contrast or brightness of the display unit 220 according to the operating parameter values recorded in the memory unit 120 among the set five levels, and sets any one step value from the touch sensor key unit 110. When a signal to be selected is input, the operating parameter value of the memory unit 120 is updated and recorded, and the brightness state of the display unit 220 is changed to an input value.

When the controller 130 monitors the USB 200 and confirms that an external device such as a computer is connected, the SD memory is recognized among the memories constituting the memory 120 so that the external device can receive various data. Allow recording or reading.

On the other hand, the controller 130 checks the parameter value recorded in the memory unit 120 and operates in the sleep mode or the power saving mode which consumes the minimum power from the normal operation mode during the designated time period. The controller 130 checks the current execution status information of all functions executed immediately before the transition to the power saving mode and records them in the allocated area of the memory unit. Therefore, when the function returns from the power saving mode to the normal operation mode, the corresponding functions that were being executed are continuously Try running or running again. As such, the execution state information recorded in the memory includes, for example, a kind of information output to the display unit 220, a kind of MP3 music signal output through the audio unit 210, and an intermediate part played. That is, in the state of operating in the power saving mode, the supply of operating power to other functional units including the display unit 220 that consumes a lot of power is completely blocked, and the operating power is supplied to the touch sensor key unit 110 for inputting a control command. In addition, the control unit 130 executes only the minimum function program necessary for monitoring and the like and blocks the execution of other functions so as to consume the minimum power.

At this time, when a specified time period has passed or when a control command signal is input from the touch sensor key unit 110, the controller 130 controls the power supply unit 190 to supply operation power to each function unit normally so that all functions are normally executed. Return to the mode. In the present invention, the time required to return from the power saving mode to the normal operation mode is within 2 seconds.

In addition, the controller 130 applies the still image and video signals recorded in the allocated area of the memory unit 120 to the contrast and resolution correction unit 170 through the charging and communication unit 100 and outputs the same to the display unit 220. When the contrast value and the resolution at the time of the optimum value is calculated to calculate the respective correction value, and control and monitor so that each corresponding correction value calculated in this way is recorded in the associated state with the corresponding data signal of the memory unit 120 do. The data signal by the still image is transmitted to the photo reduction unit 180 to control and monitor to reduce the size to one-fifth size and the selected size.

The MP3 unit 140 decodes the MP3 music signal retrieved and applied from the memory unit 120 by the MP3 protocol method and converts the MP3 music signal into an audible audio signal under the control and monitoring of the controller 130. The audio signal is applied to the audio unit 210.

The multimedia unit 150 decodes the original video signal retrieved and applied from the memory unit 120 using the EMPEG 4 method under the control and monitoring of the controller 130, and outputs an audible audio signal and a maximum of 640 * 480. The video signal is separated into a video signal of the viewing by the pixel PIXEL, and the separated audio signal is applied to the audio unit 210 and the video signal is applied to the display unit 220.

In addition, when the original still image signal is received by a photograph or the like, it is similarly decoded using the MPEG4 method and converted into a still image signal by up to 640 * 480 pixels PIXEL to the display unit 220. Output

At this time, the multimedia unit 150 checks the contrast correction value and the resolution correction value recorded in the allocated area of the memory unit 120 in a linked state with the still image and the video signal, and contrasts the image signal output to the display unit 220. Is corrected to any one of five levels, and the size by the configuration of the pixel is adjusted so that the display unit 220 displays the optimal state according to the resolution of the original. That is, the video or still image is automatically corrected and output in accordance with the contrast value displayed in the optimal state corresponding to the contrast value set in the display unit 220, and at the same time the size of the screen so as to be output in the optimal resolution according to the resolution of the original Adjust the number of pixels.

In addition, the multimedia unit 150 sequentially outputs the still image signals recorded by the control and the control of the controller 130 one by one in a predetermined time unit, and executes a slide show displayed on the display unit 220. Such a predetermined time unit preferably designates any one time selected from a time of 1 second or more in units of 1 second.

The time date unit 160 receives the calendar information from the memory unit 120 under the control and monitoring of the controller 130, analyzes the current time and date by calculation, and visually displays the video in a format suitable for display on the display unit 220. The signal is converted into a signal and output to the display unit. In this case, a time and date arbitrarily designated by the control of the controller may be displayed, and the control value is input through the touch sensor key unit 110.

The contrast and resolution correction unit 170 receives and analyzes an original signal of a still image and a video newly stored in the memory unit 120 under the control and monitoring of the controller 130 to display the optimal brightness on the display unit 220. It can calculate the resolution correction value that adjusts the displayed size by adjusting the number of contrast correction value and the configuration number of the pixel so as to show the optimal resolution, and applies it to the controller so that it is stored in the state linked to the original signal. Record it.

The photo reduction unit 180 receives the original still image signal recorded in the memory unit 120 under the control and monitoring of the controller 130, and reduces the image to a predetermined size. For example, the display size of the original still image signal is reduced. Zoom out to a size of 1 in 15 minutes. As another example, when four still image signals are to be simultaneously displayed on the display unit 220, the original signal of the still image designated by the control and monitoring of the controller 130 is reduced to a quarter size. It is preferable that the ratio of reduction according to the number of still images displayed at the same time is optimal rather than uniform.

The power supply unit 190 inputs commercial power, and supplies corresponding operating power to each functional unit under control and monitoring of the control unit 130. At this time, the voltage and current level of the operating power supplied to each functional unit may be different. And, for example, when operating in the power saving mode under the control of the controller 130, the operating power is supplied only to the touch sensor key unit 110 and the controller 130.

The USB 200 is configured to recognize the SD memory of the memory unit 120 when an external device such as a computer is connected under the control and monitoring of the controller 130, and the application for transmitting and receiving the SD data of the controller 130. By executing the program, data is transmitted and received without having a separate SD memory reader device.

The audio unit 210 adjusts the amplification rate under the control and monitoring of the controller 130, amplifies an audio signal applied from the MP3 unit 140 or the multimedia unit 150, and outputs the audible signal.

The display unit 220 is LCD (Liquid CRYSTAL DISPLAY) and sets the brightness or contrast of the signal displayed by the control and monitoring of the controller 130 in any one of five steps, the multimedia unit 150 and the time date A still image or a video applied from the unit 160 is visually displayed. That is, the video signal to be displayed is a video signal of any one or more of a still image, a moving picture, an analog clock, a digital clock, and a calendar.

The data is copied and recorded in the allocated area of the memory unit 120 (S310). In this case, it is preferable to designate an SD memory as the allocated area.

Also, the controller analyzes the original signals of the still image and the moving image recorded in the memory unit, checks the resolution value and the contrast value, and adjusts the displayed size by adjusting the number of pixels so that the display unit 220 displays the optimal state. A contrast correction value for adjusting the correction value and the brightness is calculated and recorded in the allocated area of the memory unit in association with the original signal (S320).

Since the control unit monitors the USB 200, it is confirmed whether an external device including a computer is connected (S330), and if the external device is connected, the SD memory is executed by executing a read / write application of the SD memory. The external device recognizes the SD memory. At this time, the external device writes the corresponding data into the SD memory constituting the memory unit or reads the recorded data (S340). The data includes MP3 music signals, still picture signals, moving picture signals, calendar information, and the like.

On the other hand, the control unit monitors the touch sensor key unit 110 to check whether a signal is input from the key (KEY BUTTON) that detected the static electricity (S350), if a signal is input from the key that detected the static electricity, the position of the key Analyze, control and monitor the display on the display. In addition, the controller analyzes the command assigned to the key to display a corresponding menu or to execute and control a function designated by the command (S360).

At this time, it is checked whether the command for selecting the displayed menu is input from the touch sensor key unit (S370), and when the signal for selecting the menu is input by the controller, the menu routine is executed (S380).

The menu routine is configured to execute all functions provided in the digital photo frame device according to the present invention.

Hereinafter, with reference to the accompanying drawings, the control unit searches for the time zone specified by the power savings recorded in the memory unit and compares with the current time to determine whether it belongs to the specified time zone (S400). If the current time is the time set as the power saving time zone, the digital frame according to the present invention controls the corresponding function unit to operate the power saving mode consuming the minimum power (S410).

In addition, the controller monitors the touch sensor key unit to check whether a key signal for selecting a slide show is input (S420), and when a key signal for selecting a slide show is input, the controller displays each still image stored in the memory unit by a corresponding correction value. The display unit sequentially outputs the display unit by predetermined time units in a predetermined order and visually displays them (S430). In this case, a function of simultaneously outputting a music signal by OPTION will be described later.

The control unit checks whether a key signal for selecting a preview is input from the monitored touch sensor key unit (S440), and when the preview key signal is selected and input, the control unit outputs the original signal of each still image recorded in the memory unit. The preview is reduced since it is reduced to an area of 1 in 15 minutes and 15 still images are displayed in sequence on the display. At this time, if the original signal of each still image is reduced to an area size of 1 at 15 minutes and stored, the preview signal is outputted to the display unit by 15 pieces using the reduced and stored information (S450).
