Abstract

(57) [Summary] [Problem] In the conventional method, when switching a video using a touch panel, it is necessary to individually touch and release three commands of a screen name, a video source name, and an execution key. It was Further, if the instruction is incorrect, it is necessary to instruct the incorrect item again. The touch panel has a mechanism for detecting a pressed position and a released position, and is selected when the touch panel is pressed or released from the position of the finger on the touch panel and the image source name or the screen name. It is a video switching method characterized by having a mechanism for displaying names by changing colors and shapes on the name area under the finger so that the object is not hidden by the position of the finger.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus for switching a video source and a screen, and more particularly to a system for switching a plurality of video sources and a plurality of screens using a touch panel.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 2, a video switching method using a touch panel has a screen name 201 and a video source to be switched from a screen field 200 and a video source field 210 displayed on the touch panel. The image is switched by selecting the name 213, confirming the selection, and then selecting the execution key 220.

[0003]

According to the conventional method, when the image is switched using the touch panel, the screen name,
It was necessary to individually touch and release the three of the video source name and the execution key to instruct. Further, if the instruction is incorrect, it is necessary to instruct the incorrect item again.

An object of the present invention is to provide a method for smartly switching an image with one touch and its movement.

[0005]

[Means for Solving the Problems] The above object has a mechanism for detecting a pressed position and a separated position as a touch panel, and determines a touch panel from a position of a finger on the touch panel and a position of a video source name or a screen name. This is achieved by having a mechanism for displaying the name by changing the color and shape on the area of the name under the finger so that the selected one is not hidden by the finger when pressed or released.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a video switching device used for implementing the present invention. In FIG. 1, 100 is a video source (for example, TV of 101, 102
VTR), 120 is a screen showing a video source (for example, 1
21 displays 1, 122 displays 2), 1
Reference numeral 10 is a switching device for displaying a specified video source on a specified screen, 130 is a switching control device for controlling switching, a CPU 131 for processing, a storage device 132 for storing data and operation programs, and a switching device 110.
Is configured from the interface 133, and switching is determined by an instruction from the touch panel 140.

FIG. 3 is a diagram showing how a video source and a screen are selected on the touch panel. The video source name and its area (for example, 301 is TV and 302 is VTR) are displayed in the selectable video source name column 300, and the video source to be switched is selected by selecting this.
The selectable screen column 310 shows the screen name and its area (for example, 311 is the screen 1 and 312 is the screen 2). Before describing the processing operation of video switching using the touch panel 140, the table structure of the present invention used for this processing operation will be described first.

FIG. 4 is a data table for detecting a video source displayed on the touch panel 140, screen data, and a touched location. In this example, FIG.
It is composed of the five video source data 401 to 405 shown in FIG. It should be noted that this data table exists in the storage device 132 shown in FIG.

As shown in FIG. 4, each video source data and screen data are classified into type data 400, name data 410,
It is composed of area coordinate data 420 and 440 and output data 450 to the switch 110. Type data 400
Is "1" when the target is a video source and "2" when it is a screen
To be distinguished. The name data 410 is name data to be displayed on the touch panel. Area coordinate data 4
Reference numerals 20 and 440 indicate the positions at which the video source name or screen name is displayed on the touch panel and the coordinates at the upper left and lower right of the rectangular area for determining that the data is selected by the finger. The output data 450 to the switching device is for outputting and switching the screen source and the screen data designated by the touch panel 140.

Now, the processing operation in this embodiment will be described with reference to FIGS. 3 and 5. FIG. 5 is a flowchart showing the processing operation in one embodiment of the present invention.
The CPU 131 shown in FIG. 1 performs a processing operation according to the operation program stored in the storage device 132 and in accordance with the processing procedure shown in FIG. Hereinafter, only a method of selecting a video source name and a screen name, which are the main contents of the present invention, will be described. Therefore, it is assumed that the table data in FIG. 4 has already been created.

The process begins at block 500. Data on the position and the touch strength designated from the touch panel 140 at regular intervals is provided to the CPU 131. Based on this, the CPU 131 shows the position on the touch panel 140 by the cursor 306 in FIG. 3 so that the operator can easily understand. It is determined whether or not the position of the finger is within the video source field 300 based on the coordinate data 420 and 440 of FIG. 4 (block 501). If it is in the video source field 300, the color of the area of the video source area 303 where the finger is located is changed (block 502). In this case, instead of changing the color of the area, the display shape in the area may be changed, or both the color and the shape may be changed. It is determined whether the position of the finger is in the video source field 303 and the force pressing the touch panel 140 has exceeded a certain level (block 50).
3). When the force pressing the touch panel 140 exceeds a certain level, it is determined that the video source 323 is selected, and the color of the area is changed. In addition, the cursor shape 326 is also changed so that it can be seen that it has been selected (block 50).
4). Also here, the shape data may be changed instead of the color, the color of the cursor may be changed, or the color and the shape may be changed.

Next, in order to select the screen, the finger is moved as it is to the position of the screen column 350. Whether or not the position of the finger is within the screen field 350 is determined based on the coordinate data 420 and 440 of FIG. 4 (block 50).
5). If it is in the screen column 350, the color of the screen area 351 where the finger is located is changed (block 506). in this case,
Even if you change the shape of the area instead of changing the color of the area,
Both color and shape may be changed. Position of finger is screen field 3
It is within 50 and it is determined whether or not the force for pressing the touch panel 140 is below a certain level (block 50).
7). When the force pressing the touch panel 140 is below a certain level, it is assumed that the finger is released and the screen 351 at the position of the finger is selected at that time. Since the video source name 343 and the screen name 351 have been selected, the output data to the switch of FIG. 4 is sent to the switch 110 through the interface 133 to switch the video (block 508). At block 509, the processing ends.

When the finger is in the video source column 300 or the screen column 350, the video source name 303 or the screen name 3 below the finger is displayed.
In order to hide 51 with a finger, the finger is used for the video source name 300
During the period in the area of the screen name 351 or the screen name 351, the name may be displayed as an area having a different color or shape on the area.

[0015]

According to the present invention, a single finger operation (pressing,
It can be moved and released), so comfortable video switching is possible. In addition, since the name hidden by the finger is displayed on the name field, there is an effect that an error in selecting a video source or a screen is reduced.
