Description

Method for Processing User Key Signal of Video Device

The present invention relates to a video device, and more particularly, to a method for processing a user key signal of a video device.

A video device is a device for processing an input video signal and displaying the screen using various display elements such as CRT, LCD, PDP, and the like.

Taking a monitor as an example, a memory unit 11 for storing OSD information and screen setting and various user setting information, a user key input unit 12 for setting a screen and various user setting through the OSD menu, CRT or LCD, etc. The display unit 15 of the display unit, an image processor 14 for processing the image signal input from the outside to be displayed on the display unit 15, and a key signal input through the user key input unit 12 to recognize the corresponding operation. It is configured to include a control unit 13 to control the overall system in relation to the image processing.

In this case, the user key input unit 12 generally includes a menu key for displaying an OSD menu screen on the front of the monitor, a selection key for selecting a desired detail item from the OSD menu, and a setting value (eg, brightness, Direction keys (e.g., △, ▽, ◁, ▷), etc. for changing the contrast, screen size, etc. are provided, and the key signal processing process according to the user's pressing of these keys is performed by the controller 13; This is done with reference to Figure 2 as follows.

First, when the key signal processing routine is started, the key counter value of the monitor, that is, the counter in the control unit 13 initializes the user's key input time counted to '0' (S21).

Subsequently, it is determined whether a key is input (S22). If a key is input, the key counter is increased by '1' (S23), and it is determined whether the key counter value is equal to or greater than a preset counter value (S24).

At this time, the conventional monitor is shipped with a specific counter value, which is a standard for recognizing a proper key signal, when the user's key input becomes more than that at the time of manufacture.

Therefore, if the key counter value is not equal to or greater than the preset counter value, steps S22 and S23 are repeated. If the key counter value is greater than or equal to the preset counter value, the function according to the corresponding key signal is performed once (S25).

For example, selecting 'Brightness' in the OSD menu and pressing the increment key ▷ increases the brightness by one step whenever the key counter value is greater than or equal to the preset counter value.

However, in the conventional user key signal processing method, the key response time cannot be changed and is determined by a fixed counter value. Therefore, even if the same response time is used for all users, the user may feel fast or slow depending on the user. many.

For example, if the user wants to increase the brightness of the screen by only one level, but the key operation may be poor, especially when the elderly are not free to press the finger, such as the disabled or disabled, The response time is so fast that the brightness of the screen is increased by two or three levels irrespective of one's will, which may cause inconvenience.

On the other hand, as another example, the user wants to increase the brightness of the screen by about five steps in a short time, but the response time is slow due to a slow key input until the desired brightness control is achieved, it may cause inconvenience.

Therefore, since the user key signal processing according to the prior art is performed by unilateral key input time determination regardless of the user's taste or key manipulation ability, there is a problem in that the control desired by the user is not easily performed, thereby increasing inconvenience.

Therefore, the present invention has been made to solve the above-mentioned conventional problems, the user of the monitor to solve the inconvenience caused by key input to increase or decrease the key response time to the desired level for each user It is an object of the present invention to provide a key signal processing method.

According to an aspect of the present invention, there is provided a video input device including a key input unit, a control unit, and a memory unit, wherein the control unit determines whether a key is input through the key input unit. And reading a value from the memory unit and comparing the value with the key input time count value to perform a corresponding function.

According to an embodiment of the present invention, a preset count value is displayed by a key response time setting menu included in a user menu according to a user command, and a user selects a desired user from a plurality of user lists on a key response time setting menu screen, and corresponding key response time. Is adjusted by the user's desired level, and storing the selected user and the corresponding key response time among the plurality of user lists.

Hereinafter, a preferred embodiment of a method for processing a user key signal of a video device according to the present invention will be described in detail with reference to the accompanying drawings.

3 is an example of an imaging apparatus according to the present invention, a method of setting a key response time for each user of a monitor, FIGS. 4A to 4C are diagrams showing an embodiment of a menu screen according to FIG. 3, and FIG. As an example of the video apparatus according to the present invention, there is shown a flowchart illustrating a method for processing user key signals of a monitor.

In the user key signal processing method according to the present invention, first, a process of setting a key response time for each user must be preceded, which will be described with reference to FIGS. 3 to 4C.

At this time, a menu for setting the key response speed is added to the user menu.

First, when the user presses a menu key through the user key input unit 12 of the monitor, the control unit 13 recognizes this and causes the user menu screen as shown in FIG. 4A to be displayed through the display unit 15 in OSD form.

Subsequently, the controller 13 determines whether the user presses a key response time menu key (S31).

When the user presses a key response time menu key, for example, as illustrated in FIG. 4B, the control unit 13 displays the key response time of the recently selected user (S32).

4B, a user selection item 41 for selecting a user (user A, user B ...) is displayed on the upper side, and the user can adjust the key response time on the lower side (Bar). The key response time adjustment item 42, which indicates the increase / decrease of the reaction time in the form of), is displayed, and the 'confirmation' item is displayed at the bottom.

Therefore, a user who wants to check or change the key response time in the user selection item 41 may be selected using the direction key of the user key input unit 12.

That is, when the user changes the user from 'A' to 'C' by pressing the direction key (▷) in the user selection item 41 of FIG. 4B, the key response time according to the user C is displayed as shown in FIG. 4C.

Subsequently, when the user is selected, the user (User A, User B, User C, ...) is stored (S33).

Then, it is determined whether the key response time of the currently selected user is changed (S34).

Subsequently, when the key response time is changed, the determination result (S34) stores the changed key response time (S35).

When it is determined whether or not the confirmation key is input (S36), if the confirmation key is not input, the process returns to step S32, and when the confirmation key is input, the screen returns to the previous menu screen.

On the other hand, if the determination result (S34), if the key response time is not changed, if the confirmation key is not entered, returns to the step (S32), and if the confirmation key is input, returns to the previous menu screen.

Through the above-described process, the key response time for each user and the currently selected user are stored, thereby completing the key response speed setting.

Next, a method of processing an actual user key signal in a state where key response rate setting is completed as described above will be described with reference to FIG. 5.

First, when the key signal processing routine is started, the current user is identified and the key response time set by the current user is designated as a variable, that is, a "user counter value" (S51).

At this time, the "user counter value" is similar to the conventional one in the sense of the reference value for the signal processing according to the key counter, but is a fixed value at the time of manufacture, but in the present invention is set for a plurality of users, each value is adjustable .

Subsequently, a key counter value of the monitor, that is, a value in which the counter inside the control unit 13 counts the key input time of the user is initialized to '0' (S52).

Subsequently, it is determined whether a key is input (S53). If a key is input, the key counter is increased by '1' (S54), and it is determined whether the key counter value is greater than or equal to the user counter value (S55).

Therefore, if the key counter value is not equal to or greater than the preset counter value, steps S53 and S54 are repeated. If the key counter value is greater than or equal to the preset counter value, the function according to the corresponding key signal is performed once (S56).

For example, selecting 'Brightness' in the OSD menu and pressing the increment key ▷ increases the brightness by one level whenever the key counter value is greater than or equal to the user counter value.

However, since the key response speed is set differently for each user, the actual brightness increase time also varies from user to user.

In other words, if the user wants a quick key response, if the key response time is set quickly, the actual screen brightness increases quickly according to the increase key input, while if the user wants a slow key response, the key response time is set slow. As a result, the actual screen brightness increases slowly.

In the user key signal processing method of a video device according to the present invention, since a plurality of users can set the key response speed to their desired level, it is convenient for the user by eliminating the inconvenience such as performing a function too slow or fast according to the key input. Has the effect of providing.
