The sync separation circuit 3 separates the horizontal sync signal HSY and the vertical sync signal VSY from the video signal SV. Separated horizontal sync signal HSY and vertical sync signal VSY
Is supplied to the position detection circuit 4.

In the position detecting circuit 4, the timing at each time point in the video signal SV is converted into coordinate data within one screen based on the above-mentioned horizontal synchronizing signal HSY and vertical synchronizing signal VSY. This coordinate data is, for example, in a frame [one screen], data representing the position on the Y axis represented by the number of horizontal scanning lines and the position on the X axis represented by the position within one horizontal scanning line. And data representing

That is, at a certain timing, the nth horizontal scanning line is scanned with the vertical synchronizing signal VSY as the reference in the Y-axis direction, and the horizontal synchronizing signal HSY is used as the reference in the X-axis direction. If m seconds have elapsed since the start, position information within the frame of (m, n) can be obtained.
Then, this position information is converted into the coordinate data on the corresponding plane, and the coordinate data as the reference position information is formed. The coordinate data is supplied to the system controller 5, the icon controller 6, and the cursor controller 7 as timing information and position information, respectively.

On the other hand, a light receiving portion 8 for receiving a remote control signal is connected to the system controller 5,
The signal from the light receiving unit 8 is supplied to the system controller 5. A mouse 9 for moving the cursor and selecting a command by the cursor is connected to the system controller 5, and a signal from the mouse 9 is transmitted to the system controller 5.
Is supplied to. Further, a key operation unit 10 for key input is connected to the system controller 5, and the key operation unit 1
The signal from 0 is supplied to the system controller 5.

In the system controller 5, the light receiving section 8,
Various types of data supplied from the data input means such as the mouse 9 and the key operation unit 10 are processed. The processed data and necessary data are supplied to each circuit block.
For example, the command regarding the movement of the cursor CS input by the above-mentioned data input means, the coordinate data of the target position, and the current coordinate data of the cursor CS,
It is supplied to the icon controller 6 and the cursor controller 7.

In the icon controller 6, based on the coordinate data from the position detection circuit 4, that is, the reference position information,
A control signal that causes the character signal corresponding to the icon 21 to be output is formed at a predetermined timing. The control signal is supplied to the character generator 11.

The cursor control circuit 7 generates a character signal corresponding to the cursor CS based on the reference position information supplied from the position detection circuit 4 and the display position information of the cursor CS supplied via the system controller 5. A control signal for output is formed. The control signal is supplied to the character generator 11.

In the cursor control circuit 7, the data from the position detection circuit 4 is used as reference position information, and the coordinate data of the cursor CS currently displayed on the tube surface is used as current display position information. In addition, the system controller 5
The coordinate data, which is supplied via the and serves as the movement target of the cursor CS, is the target display position information.

The case of the plane movement processing will be described. In the case of this plane movement processing, the cursor CS is moved frame by frame so that the cursor CS can move from the current display position to the target display position within a predetermined number of frames.
The coordinate data of the display position is obtained. And the cursor
The CS coordinate data is sequentially converted into previously obtained coordinate data for each frame. As a result, the display position information of the cursor CS in each frame is formed. Then, based on the timing corresponding to the display position information in each frame, the screen display is performed in each successive frame. When you see this on the screen, the cursor CS appears to move continuously.

When the cursor CS is located near the icon 21, the cursor CS is pulled into the icon 21. In the case of this pull-in, first, the cursor
It is determined whether or not the current display position information of CS is included in the second area AR2 set around the icon 21. Only when it is determined to be included, the coordinate data of the third area AR3 including the cursor CS is converted into the coordinate data of the predetermined area which is the first area AR1 and the second area AR2 and in which the cursor CS is drawn. To be done. Then, the tube surface is displayed at the timing corresponding to the coordinate data. As a result, if the cursor CS is included in the second area AR2, the display on the screen as if the cursor CS was drawn into the icon 21 is made in an instant.

The character generator 11 forms a character signal based on the control signal. If the character generator 11 is composed of, for example, a ROM, the icon controller 6 and the cursor controller 7 supply the address data in which the character code is stored and the read signal that defines the read timing. The character signal is supplied to the adding circuit 15.

The addition circuit 15 adds the character signal to the video signal SV0. The video signal SV1 on which the character signal is superimposed is supplied to the display 12. On the display 12, various icons, graphic characters such as a cursor, etc. are displayed on the screen based on the video signal SV1.

The operation of this embodiment will be described below. A screen 12a of the display 12 is shown in FIG. On this screen 12a, the cursor CS on the "arrow"
The icon 21 is displayed on the screen. Icon 21
A switch control icon, that is, a rewind icon 21a, a play icon 21b, a fast forward icon 21c, a stop icon 21d, etc. is displayed.

Here, the icon 21, the cursor CS, and the areas set around them will be described with reference to FIGS. A rewind icon 21a is used as an example of the icon 21.

As shown in FIG. 3, the rewind icon 2
The entire 1a is set as the first area AR1, and the position P21c is centered on the position P21c of the first area AR1.
The second area AR2 is set within a circle having a radius R.
The rectangular display area including the cursor CS is set as the third area AR3.

The flowchart of FIG. 4 will be described below with reference to FIG.
This will be described with reference to FIGS. 5 to 13. As a premise of the following description, the coordinate data of the first area AR1 and the second area AR2, the coordinate data in the first area AR1 and the second area AR2, and the coordinate data corresponding to the retracted position of the third area AR3. , And the cursor CS at each timing
The coordinate data and the like before the movement are stored in the system controller 5 and supplied to the icon controller 6 and the cursor controller 7 as necessary.

Further, in the system controller 5, it is assumed that the coordinate data of the third area AR3 is determined by the data input means such as the light receiving portion 8, the mouse 9, the key operating portion 10 and the like. In the following description, the reproduction icon 21b is used as an example of the icon 21.

In step 101, it is determined whether or not the cursor CS is located near the reproduction icon 21b. That is, it is determined whether or not at least part of the third area AR3 including the cursor CS is in the second area AR2. If at least part of the third area AR3 is the second
If it is determined that it is in area AR2, step 102
Go to step 105, and if it is determined that it is not entered, go to step 105.

At least a part of the third area AR3 is the second area AR3.
The determination as to whether or not it is included in the area AR2 will be described with reference to FIG. That is, the four vertices P3a of the third area AR3,
If at least one of the coordinate data of P3b, P3c, and P3d is in the second area AR2, it is determined that the third area AR3 is in the second area AR2. In the example of FIG. 3, it is determined that the third area AR3 is in the second area AR2. A state in which the cursor CS is approaching the reproduction icon 21b is shown in FIGS.

In step 105, plane movement processing is performed. This plane movement process is performed by the cursor as described above.
The coordinate data of the display position of the cursor CS is obtained for each frame so that the CS can move from the current display position to the target display position within a predetermined number of frames. Then, the coordinate data of the cursor CS is sequentially converted into the predetermined coordinate data which has already been obtained for each frame. This allows the cursor in each frame
The display position information of CS is formed.

Then, the screen display of the cursor CS is performed at the timing defined by the display position information for each frame. Since this is done in each successive frame, when this is seen on the screen, a display is made such that the cursor CS moves continuously. When this plane movement processing ends, the process returns to step 101.

At step 102, the cursor CS is drawn to the center of the reproduction icon 21b. Figure 3
, The point P21c that is the center of the playback icon 21b
The cursor CS is moved so that the position of the point P3e at the tip of the cursor CS coincides with the position of.

This is done as follows. First
In the area AR1 and the second area AR2, coordinate data of a predetermined range corresponding to the retracted position of the cursor CS is supplied from the system controller 5 to the cursor controller 7.

In the cursor controller 7, the cursor CS
The coordinate data of the point P3e at the tip of the is converted into the coordinate data of the point P21c of the reproduction icon 21b. Similarly, all the coordinate data of the points forming the third area AR3 are converted into the coordinate data of the predetermined area which is the first area AR1 and the second area AR2 and into which the cursor CS is drawn. To be done.

Then, the coordinate data of the reference position information supplied from the position detection circuit 4 and the point P at the end of the third area AR3.
A comparison is made with the coordinate data of 3a. Then, a control signal that causes the character signal corresponding to the cursor CS to be output is supplied to the character generator 11 at the timing when the values of both coordinate data match.

In the character generator 11, the character code representing the cursor CS is read at the timing when the display control signal is supplied and supplied to the addition circuit 15.

As a result, the display 12 displays the point P21c at the center of the reproduction icon 21b and the point P3e at the tip of the cursor CS, for example, in the state shown in FIG. This is a state in which the cursor CS is drawn into the playback icon 21b within an instant. This state is shown in FIGS. 9 and 10. Then, the process proceeds to step 103.

At step 103, it is judged whether or not the cursor CS has been drawn to the center of the reproduction icon 21b. This determination is made by, for example, the point P3e at the tip of the cursor CS.
Is performed depending on whether or not coincides with the center point P21c of the reproduction icon 21b. If they do not match, the process returns to step 102. If they match, the process proceeds to step 104.

In step 104, the state in which the cursor CS is pulled in by the reproduction icon 21b is continued for a predetermined time after the cursor CS is pulled in by the reproduction icon 21b, and the state is kept. Then, when the predetermined time has elapsed, the holding state is released, and as shown in FIG.
The CS can be moved freely, and the process moves to the plane movement process again.
Then, the process returns to step 101.

In FIGS. 8 to 12, the cursor CS is drawn close to the reproduction icon 21b, and after the holding state,
The process in which the cursor CS can be moved again is shown. 8 to 13 are schematic diagrams showing the positional relationship between the cursor CS and the reproduction icon 21b and the state in which the cursor CS is pulled in. In the schematic diagrams of FIGS. 8 to 13, the cursor CS is represented as a spherical cursor CSB, and the second area AR2 is represented as a groove 25 having an inclined surface.

In FIG. 8, the cursor CSB is moved to the right [FIG.
Middle, arrow R direction], and a state of approaching the groove 25 which is the second area AR2 is shown. Then, FIG. 9 shows a state in which the cursor CS is drawn into the second area AR2. In FIG. 9, the above-mentioned retraction is shown by showing a state in which the cursor CSB is falling in the groove 25. That is, a state is shown in which the cursor CS is drawn into the second area AR2 within an instant, such as when the cursor CSB falls in the groove 25.

Then, FIG. 10 shows a state in which the cursor CSB reaches the position of the bottom of the groove 25 and is stopped. This shows a state where the drawing of the cursor CS into the second area AR2 is completed.

When the cursor CS is drawn into the reproduction icon 21b and a predetermined time elapses, the groove 25 disappears and a flat surface 27 is formed, as shown in FIG. That is, the holding state is released and the cursors CS and CSB can be moved freely. Therefore, the cursor CSB shown in FIG. 11 is free to move in the left-right direction [in the direction of arrow LR in FIG. 11].

As shown in FIG. 12, the cursor CS moves away from the reproduction icon 21b and moves leftward [indicated by arrow L in FIG. 12].
Direction]. Then, as shown by the broken line in FIG. 12, the cursors CS and CSB are the reproduction icons 21b.
When you get out of the second area AR2 set around,
Again, it returns to the initial state of FIG.

According to this embodiment, at least a part of the coordinate data of each point forming the third area AR3 is the second area.
If it is determined to be in area AR2, third area AR
The coordinate data of all the points composing 3 are the first area.
It is converted into the coordinate data of the AR1 and the second area AR2 and the coordinate data of the range of the retracted position of the cursor CS.
Then, since the screen is displayed at the timing corresponding to the converted coordinate data, the cursor CS is displayed as the play icon 21b.
In the moment, he appears as if he was pulled in in a moment.

Therefore, no skill is required to operate the mouse when the cursor is aligned with the icon, and the mouse operation can be facilitated.

FIG. 1 shows another embodiment of the present invention.
This will be described with reference to FIGS. Another example is
The difference from the above-described embodiment is that a sound effect is output in response to the movement of the cursor CS. The same parts as those in the above-described embodiment are designated by the same reference numerals, and the duplicated description will be omitted.

The structure is shown in FIG. In addition to the configuration of the embodiment shown in FIG. 1, a sound generator 16 and a speaker 17 are connected to the system controller 5. This makes it possible to generate various sound effects.

14 to 17 show the correspondence between the movement of the cursor CS and the sound effect. This will be described below. As shown in FIG. 14, when the cursor CS0 moves in a fine manner such as moving to the position of the cursor CS1, for example, a sound effect such as “toco, toco, toco” is output. Further, as shown in FIG. 15, when the amount of movement is large such that the cursor CS0 moves to the position of the cursor CS1, for example, a sound effect such as “shoes” is output.

As shown in FIG. 16, when the cursor CS is drawn to the reproduction icon 21b, a sound effect such as "bush" is output.
Further, as shown in FIG. 17, when the user clicks after being drawn into the playback icon 21b, for example,
A sound effect such as "pin" is output.

According to another embodiment, in addition to the configuration of the above-described embodiment, a sound generator 16 and a speaker 17 are connected to the system controller 5, and a cursor is used.
It is possible to generate various sound effects corresponding to the movement of CS.

Therefore, in addition to the effect of the above-described embodiment,
It is possible to generate various sound effects corresponding to the movement of the cursor CS, which improves the user's operating environment. For example, it is possible to experience the actual movement of the cursor CS, which makes the operation more enjoyable, and even when the movement of the cursor CS is felt to be dull, it is resolved by the sound effect.
