Description

Video recording / reproducing apparatus and method for displaying the mode conversion icon and displaying method thereof {Video recording / reproducing apparatus and method of displaying mode transformation icon}

The present invention relates to an image recording / reproducing apparatus and a mode displaying method thereof, and more particularly, to an image recording / reproducing apparatus supporting the mode switching state display function upon continuous mode switching command input and a display method thereof. .

The video recording / reproducing apparatus is generally used as a camcorder. Camcorder is a combination of a camera and a video cassette recorder (VCR), which is a compact integration of a video camera and a recording / playback device. Also called a camera integrated VCR or just a video camera

In other words, it is a low-cost compact camera that allows ordinary people to easily and freely record their own videos. With the development of current electronic and optical technologies, camcorders are now 8mm and 6mm smaller than normal VHS video tapes. And digitalization.

Fig. 1 shows a general block diagram of such a camcorder, i.e., a video recording / reproducing apparatus, in a simple block diagram. According to the drawing, the video recording / reproducing apparatus includes a key input unit 10, a control unit 20, a display character generator 30, a display unit 40, a VCR unit (video cassette recorder) 50, and a camera unit 60. ) And an adder 70.

In the case of a digital camera, the camera unit 60 generally includes a lens unit, a charge coupled device (CCD), a camera signal processor, a video / audio signal processor, and a microphone to capture an external image to capture image information and audio information. And converting the video into video information including additional information. That is, after imaging the subject to be imaged through the lens unit, the formed optical image is photoelectrically converted into an electrical signal by the CCD. The camera signal processor receives an electrical signal from the CCD and converts the signal into digital video data. The microphone converts an audio signal input from the outside into an electrical signal and outputs it to the video / audio signal processor. The video / audio signal processor transmits the data received from the camera signal processor and the microphone to the display unit 40 through the adder 70 so that an image corresponding to the digital video data is displayed. Since the action of the camera unit 60 is generally known, detailed description and illustration will be omitted.

The VCR unit 50 plays a role of recording and playing back moving image data captured by the camera unit 60. The VCR unit 50 may include a recording medium (eg, a video tape) and a VCR deck capable of recording moving image data.

Meanwhile, the key input unit 10 serves to receive a command for selecting a mode of the video recording / reproducing apparatus from the outside. In other words, the device allows the user to select a key to select the playback, stop, pause, fast forward (FF), rewind (REW), and recording modes.

The controller 20 generally controls the video recording / reproducing apparatus according to the command input from the key input unit 10.

The display character generator 30 is controlled by the controller 20 to generate a mode icon of a certain form corresponding to the mode of the current video recording / reproducing apparatus. For example, create an icon such as ▷ in playback mode or □ in stop mode.

The display unit 40 functions to display the motion picture data captured by the camera unit 60 and the mode icon generated by the display character generator 30 on the screen. It is generally implemented as an LCD panel (Liquid Crystal Display Panel). The mode icon is generally displayed on one corner of the screen so as not to interfere with watching the video data.

The adder 70 functions to add the motion picture data captured by the camera unit 60 and the mode icon generated by the display character generator 30 to output to the display unit 40.

On the other hand, FIG. 2 sequentially shows a change in the mode icon display state of the display unit 40 when a mode change command is continuously input in the video recording / reproducing apparatus having the structure of FIG. FIG. 2 shows, for example, the case where the playback, stop, and fast forward buttons are continuously pressed on the video recording / reproducing apparatus currently in the stopped state.

When the play key is input in the stop mode (stop mode) (a of FIG. 2), the mode icon (▷) corresponding to the play mode is displayed on a certain portion of the screen while switching from the stop mode to the play mode (FIG. 2). B). In general, when a mode conversion command is input, it takes a certain time until the conversion from the mode currently in progress to the mode corresponding to the command is completed, whereas the icon indicating the current mode is the mode corresponding to the input mode conversion command. Since the display is converted directly to an icon, there is a problem that does not match between the actual screen state and the displayed mode icon.

On the other hand, if the stop key is continuously input before the conversion from the stop mode to the reproduction mode is completed, the mode icon is converted back to the stop mode icon (□) (Fig. 2C). In this state, when the fast forward (FF) key is input again and the conversion to the playback mode is completed at that time, the screen shows the playback mode, but the mode icon indicates the fast forward mode (▷▷) (Fig. 2D). ).

If there is no more input, the mode icon keeps the fast forward mode (▷▷), the video recording / playback device switches from the playback mode back to the stop mode (Fig. 2e), and fast forwards again in the stop mode. The mode is switched to (FIG. 2F).

According to the conventional mode icon display method as illustrated in FIG. 2, a mode in which the mode currently being displayed on the screen and the mode represented by the icon do not coincide with each other. Therefore, the user may not accurately know the current operation state of the video recording / reproducing apparatus, and thus, a problem arises in that the mode switching button is reactivated several times.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to display the input mode conversion command collectively on the same screen when a mode change command is continuously input, and allow the user to record / play back images.

Hereinafter, the present invention will be described in more detail with reference to the drawings. The present invention will be described with reference to a block diagram showing the general configuration of the conventional video recording / reproducing apparatus shown in FIG. 1, and the same parts as those shown in FIG. 1 are denoted by the same reference numerals.

3 is a view illustrating a mode icon display form finally displayed by the display unit 40 when a continuous mode change command is input in the video recording / reproducing apparatus according to the present invention. The case of continuously inputting is described as an example. In the drawing, the first position 41 on the screen is a position for displaying the current mode icon corresponding to the progress mode of the current video recording / reproducing apparatus, and the second position 42 is a mode change command input during the current mode progression. The location to display the corresponding standby mode icon. In addition, the third position 43 is a position for displaying the registration standby mode icon indicating that the mode conversion is in progress according to the input mode conversion command. Therefore, when the mode change corresponding to the icon displayed in the second position 42 is started, the same icon as the mode icon of the second position 42 is displayed in the third position 43. The fourth position 44 is a portion for displaying a mode icon corresponding to the second input command when the mode change command is continuously input.

In the above example, since the playback mode is currently in progress, the playback mode icon is displayed at the first position 41 and the stop key is first input, and thus the mode icon corresponding to the playback mode icon is displayed at the second position 42. On the other hand, when the conversion to the standby mode starts after a predetermined time has passed after the mode conversion command is input, the conversion target mode is displayed in the third position 43 as a registration standby mode icon. That is, the registration standby mode icon has the same shape as the standby mode icon.

When the FF key is continuously input after the stop key is input, an icon (▷) corresponding thereto is displayed in the fourth position 44 as the secondary standby mode icon. In this way, by continuously displaying the mode change command input as an icon on one screen, the user can easily find out the current mode, the next mode and the mode of the reserved mode. Meanwhile, although FIG. 3 sets first to fourth positions based on the upper right side of the screen, any part of the screen may be arbitrarily set as long as it does not interfere with screen listening.

4 shows a change in the display state of the display unit 40 when the playback and stop keys are continuously input in the video recording / reproducing apparatus of the present invention in the stop state. According to the drawing, first, the stop mode icon? Is displayed as the current mode icon at the first position on the screen in the stop mode (a in FIG. 4).

At the same time as the playback key is initially input, the playback mode icon? Is displayed as the standby mode icon at the second position 42 on the screen (b of FIG. 4). In this state, the conversion to the reproduction mode has not yet started and the stop mode state is maintained.

On the other hand, when conversion to the reproduction mode is started, the reproduction mode icon is displayed at the third position 43 as the registration standby mode icon (Fig. 4C).

On the other hand, when the stop key is continuously input as the secondary mode change command, the stop mode icon? Is displayed as the secondary standby mode icon at the fourth position 4 (d in Fig. 4).

After the reproduction key and the stop key are continuously input in this way, when the conversion from the stop mode to the reproduction mode is completed (FIG. 4E), the conversion is started again in accordance with the conversion instruction to the stop mode that is in standby (FIG. 4). F). In this case, the stop mode icon? Is displayed at the second position 42 and the third position 43.

When the conversion to the stop mode is completed, the display unit enters the stop mode while displaying the stop mode icon? At the first position 41 (g in Fig. 4).

The display state of the display unit 40 is controlled by the control unit 20 shown in the general configuration diagram of the video recording / reproducing apparatus of FIG.

That is, the mode conversion command from the user is input through the key input unit 10. The key input unit 10 outputs a mode conversion command input to the control unit 20.

The controller 20 controls the display character generator 30 to generate a mode icon corresponding to the input mode conversion command. The display character generator 30 generates icons such as ▷, □, ▷▷,,, ◁◁, and the like.

As described above, the camera unit 60 captures an external image and converts it to moving image information including image information and audio information. The VCR unit 50 records and reproduces the moving image information. When a mode change command is input, the camera unit 60 and the VCR unit 50 switch to a mode corresponding to the command to perform a function of recording, stopping, and playing.

The adder 70 sums up the video information output from the camera unit 60 and the mode icon output from the display character generator 30, and outputs the result to the display unit 40, which is displayed by the display unit 40. It is displayed on the screen in the same manner as shown in FIG.

Meanwhile, the controller 20 displays a mode icon according to the mode conversion command and performs an operation corresponding to the input command. That is, when the playback mode conversion command is received, the VCR 50 controls the video clip information, and when the recording mode conversion command is received, the camera 60 controls the camera 60 to capture an external image. On the other hand, when there is a waiting mode change command, when the current mode change is completed, the conversion process to the mode corresponding to the standby mode change command is automatically started.

5 is a flowchart illustrating a process of displaying a mode icon under the control of the controller 20.

According to the drawing, when the mode input key (command) is received at the key input unit 10 (S510), the display character generator 30 generates a standby mode icon corresponding thereto, and displays the screen through the display unit 40. A predetermined position on the image, that is, the second position 42 is displayed (S520).

When the mode conversion is started according to the input command (S530), the same icon as the standby mode icon is displayed in the third position 43 as the registration standby mode icon (S540).

On the other hand, if it is determined that the secondary mode conversion command is input in the state in which the mode conversion to the registered standby mode is not completed (S550 and S560), a secondary standby mode icon is generated and displayed in the fourth position 44. It is made (S570).

On the other hand, as shown in FIG. 3, when the second standby mode conversion command is input, when the conversion from the current mode to the registration standby mode is completed, the mode conversion command that is waiting is automatically performed. At this time, the display unit 40 deletes all the mode icons that are being displayed, displays the stop mode icon (□) at the first position 41, and displays the secondary standby mode icon (▷▷) as the standby mode icon and registration. The standby mode icon is displayed in the second position and the third position.

Meanwhile, according to an embodiment of the present invention, after a continuous key input is performed in the video recording / reproducing apparatus, the pending mode change command may be canceled by using the delete key.

6 is a flowchart for explaining a processing process when such a delete key is input. According to the drawing, when a cancel key is input (S610), it is determined whether there is a secondary standby mode conversion command, and if so, the command is canceled and the secondary standby mode icon is deleted (S620 and S630).

If there is no secondary standby mode conversion command, if there is a primary standby mode conversion command, it is determined whether conversion to the standby mode has been started (S640, S650). If the conversion process is not started, the first standby mode conversion command is canceled and the standby mode icon is deleted (S660). On the other hand, when the conversion process is currently in progress, that is, when the registration standby mode icon is displayed in addition to the standby mode icon, the standby mode conversion command is not canceled.

According to this method, even in the case of continuous key input, it is possible to match the actual ongoing mode and the mode icon display.

As described above, according to the present invention, when the mode change command is continuously input, the user can accurately recognize the mode state of the current video recording / reproducing apparatus by accurately displaying the mode change process and the current mode as icons. To help. In addition, it is possible to cancel the mode conversion command continuously input by using the delete key, so that the user can easily correct the key input by mistake.

In addition, although the preferred embodiment of the present invention has been shown and described above, the present invention is not limited to the specific embodiments described above, but the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Of course, various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
