2B is a diagram illustrating a second embodiment of a video device with a still image editing recording function according to the present invention.

2C is a diagram illustrating a third embodiment of a video device having a still image editing recording function according to the present invention.

Hereinafter, referring to FIGS. 1 to 2C, a method of implementing still image editing recording functions by components in a video device according to the present invention will be described.

As shown in FIG. 1, the video device 102 according to the present invention includes an A / V switching unit 103, an LPF 104, a decoder & converter unit 105, a scaler unit 106, and a display unit ( 107), the PLD unit 108, the PVR control unit 109, the storage unit 110, the main control unit 111, and the memory 112.

However, the external device 101 connected to the video device 102 transmits specific A / V data to the video device 102 to enable recording.

The external device 101 may be, for example, a camcorder, a digital versatile (Video) disk (DVD) player, a PC, or the like.

The A / V switching unit 103 receives the A / V data from the external device 101, switches the video data to the LPF 104, and the audio data is the decoder and converter unit 105. To send).

The A / V switching unit 103 serves to switch only data of a specific format among data of various formats, and the data of the specific format includes a Y / Pb / Pr signal, an R / G / B signal, and the like. May be

The LPF 104 is a low pass filter that filters external noise signals and the like.

The decoder & converter 105 decodes the encoded A / V data, and converts the encoded A / V data into digital data when the transmitted A / V data is analog data.

The scaler 106 scales the A / V data transmitted from the decoder & converter 105 to be converted into a form that a user can check on the screen.

The display unit 107 outputs the scaled A / V data.

The PLD (Programmable Logic Device) unit 108 stores the A / V data transmitted from the external device 101 according to a data clock signal (CLK), and stores the storage unit 110 of the video device 102. Process in a data format that can be stored in.

The PVR control unit 109 stores the A / V data transmitted from the external device 101 in the storage unit 110 under the control of the main control unit 111.

The storage unit 110 may be, for example, a hard disk drive (HDD).

The main controller 111 controls the overall PLD unit 108, the PVR control unit 109, the memory 112, and the like, and may be, for example, a CPU or a microcomputer.

The main controller 111 may exchange control signals with the PVR controller 109 through Peripheral Component Interconnect (PCI) communication.

In particular, in relation to the present invention, a process of operating the components in the imaging apparatus 102 will be described in more detail as follows.

First, when the specific data from the external device 101 is to be stored in the video device 102, under the control of the main control unit 112, the display unit 107 is as shown in FIG. 2A. Print the screen.

If the still image editing recording function is set to be executed through a user input unit (not shown), the main control unit may store the image data input from the external device 101 in the storage unit 110. 111 receives information on a frame from the PVR controller 109.

The main controller 111 determines whether there is no interframe variation of the image data for a predetermined time or more.

Whether there is no variation between the frames may be determined by scanning the entire line of the screen or by scanning only a specific line and checking whether or not the pixel has changed.

However, the predetermined time may be arbitrarily determined, or under the control of the main controller 111, the display unit 107 may output a screen as shown in FIG. 2B and may be determined by the user's selection.

As a result of the determination by the main control unit 111, when there is no interframe variation, the main control unit 111 stores the data position of the first time point without any interframe variation in the memory 112.

When there is no variation between frames as a result of the determination by the main controller 111, the main controller 111 controls the display unit 107 to check whether the image currently being output is a normal image. Print the UI screen.

Of course, the data after the frame without the interframe variation are continuously stored in the storage unit 110, and the main controller 111 again checks whether there is a frame with no variation for more than a predetermined time. .

In some cases, the main control unit 111 controls the PVR control unit 109 and immediately continues the predetermined time period without outputting a UI screen for confirming whether the video currently being output is a normal video. The still image frame may be deleted, and then control may be performed so that data is continuously stored.

Whether to output a UI screen for confirming whether the currently output image is a normal image or not may be determined according to a user selection by outputting a screen as shown in FIG. 2C in advance.

In the UI screen for confirming whether the image currently being output is a normal image, if an input signal for confirming the normal image is applied through a user input unit (not shown) or the like, the portion without change between frames is not deleted. Under the control of the main control unit 111 and the PVR control unit 109, normal recording is continued.

On the other hand, in the UI screen for confirming whether the image currently being output is a normal image, through the user input unit (not shown), the input signal for confirming the abnormal image is applied will be divided into two cases will be described. .

Before the user judges, if there is a change in the frame, the PVR control unit 109 controls the data stored between the first time without the change in the frame and the change in the frame under the control of the main control unit 111. ) Delete.

On the other hand, if there is no change in the frame continuously (for example, there is no change in the frame before the key is input), the data stored in the storage unit 110 is deleted after the initial time when there is no change in the frame. In addition, the display unit 107 is controlled to output a UI screen for inputting a button (for example, a “PLAY” button) for playing the external device 101.

The main controller 111 analyzes an input signal applied from the external device 101.

When an input signal such as a “PLAY” button is applied through the external device 101, the main controller 111 issues a recording resume command to the PVR controller 109, and transmits data to the storage unit 110. Store in succession.

Thereafter, the main control unit 111 controls the PVR control unit 109 to resume the change monitoring routine of the video frame.

Hereinafter, an example of a control method of a video device having a still image editing recording function according to the present invention will be described with reference to FIG. 3 (see FIGS. 1 to 2C).

A command for recording A / V data or the like from an external device is input (S301).

It is determined whether a signal such as A / V data is input from the external device (S302).

As a result of the determination (S302), when a signal such as A / V data is not input from the external device, recording is not proceeded any more (S313).

On the other hand, when a signal such as A / V data is input from the external device (S302), it is determined whether the frame of the applied data is changed within a predetermined time (S303).

However, the predetermined time may be automatically set, or the screen as shown in FIG. 2B may be displayed in advance and selected by the user.

As a result of the determination (S303), when there is no change in the frame of the applied data within a predetermined time, a UI screen informing the user that there is no change is output (S304).

Of course, it is also possible to design such that frames without change in the predetermined time are immediately deleted without outputting the UI screen.

With reference to the UI screen, it is determined whether the frames which have not changed during the predetermined time are normal screens (S305).

As a result of the determination (S305), when the determination is made to the normal screen, normal recording continues, and it is checked whether or not the frame change occurs again (S312).

If the determination result (S305) does not determine that the normal screen, that is, if the user determines that the abnormal screen, the user determines whether there is a change in the frame again before determining again (S306).

As a result of the determination (S306), when a change in the frame occurs again, only the portion where the change of the frame does not occur is deleted (S311).

On the other hand, if the frame change does not occur again in the determination result (S306), the first data position without the frame change is identified first, and the data stored after the initial time point is deleted (S307).

It is checked whether a command signal such as a "PLAY" button for reproducing the external device is applied (S308).

In operation S309, it is determined whether a command signal such as a "PLAY" button of the external device is applied.

As a result of the determination (S309), when a command signal such as a "PLAY" button of the external device is applied, the video device continuously records data at the time when the frame change occurs again from the first time when there is no frame change. (S310).
