Description

Video processing apparatus and video processing system

The present invention relates to a video processing apparatus and a video processing system for performing processing using press on a key.

In recent years, with the spread of the Internet, it has become possible to browse WEB pages on the Internet and display content such as videos / still images and games on digital televisions, broadcast receivers (eg, set-top boxes), and the like. . In many cases, such a user interface is designed on the assumption that a mouse connected to a personal computer is used to operate a cursor displayed on the screen.

Therefore, when operating such content with a conventional television or set-top box remote controller, it is necessary to operate the cursor displayed on the screen by operating keys (buttons) on the remote controller. Hereinafter, in this specification, the key is a button.

Patent Document 1 discloses a technique for moving a cursor easily using a remote controller (hereinafter also referred to as related technique A). Specifically, Related Technology A operates a cross key provided on the remote controller to move the cursor to a target position on the screen.

In the following, the keys for moving the cursor are also referred to as cross keys or up / down / left / right keys. The cross key includes an up key, a down key, a left key, and a right key. In the following, each of the up key, down key, left key, and right key is also referred to as a direction key.

When the cross key is pressed, the output information from the remote controller indicates a state where the direction key is pressed (ON) or a state where the direction key is not pressed (OFF). In the following, a code for specifying a key is also referred to as a key code or key information. When the direction key of the remote controller for operating the broadcast receiving apparatus is pressed, the key code of the direction key is transmitted to the broadcast receiving apparatus.

When moving the cursor displayed on the broadcast receiving device, the cursor moves in that direction only when the direction key is pressed. The user operates the direction key to move the cursor to a desired selection target item. Here, the selection target item is an item to be selected. The selection target item is classified into a link object or a non-link object. The link object is an object (item) that is linked. The link object is, for example, a hyperlink image or hyperlink text. The hyperlink image and the hyperlink text are associated with specific information. A non-link object is an object (item) that is not linked.

This makes it possible to move to another item to be selected (for example, a link object) and execute a specific function by item selection.

When a user displays a WEB page on the Internet on a monitor using a broadcast receiving device, the monitor may not be able to display the entire image of the WEB page due to limitations such as monitor resolution and monitor screen size. is there.

In this case, the monitor may display only a part of the image of the WEB page. In order for the user to view an image of a portion that is not currently displayed on the monitor, it is necessary to scroll the image displayed on the monitor vertically or horizontally. Hereinafter, the image displayed on the monitor is also referred to as a display image.

For example, the following scroll methods A, B, and C are known as methods for scrolling an image using the above-described conventional technology. The scroll method A is, for example, a method in which an image is scrolled by pressing (operating) a direction key (cross key) to move the cursor to the end of the screen and further pressing the direction key. The scroll method B is, for example, a method in which the cursor is moved to the position of a scroll button (or scroll bar) arranged on the screen and the image is scrolled by pressing the scroll button. The scroll method C is a method in which a separate scroll key is provided on the remote controller and the key is operated.

First, in the scroll method A, before scrolling the image, the direction key must be pressed to move the cursor to the end of the screen. Further, when scrolling an image in a direction opposite to the scroll direction of the image, the cursor must be moved from one end of the screen to the other end. Therefore, it takes time to move the cursor. When the image is scrolled, the cursor is at the end of the screen. Therefore, in order to select a selection target item (for example, a link object) indicated by the display image, the number of times the user operates the cursor increases. Therefore, usability is very bad.

In the scroll method B, an operation for pressing the scroll button displayed in the display image is performed. Specifically, in the scroll method B, the user moves the cursor to the position of the scroll bar, and the user presses a confirmation key separately provided on the remote controller in a state where the cursor is accurately aligned with the position of the scroll button on the scroll bar. This operation is necessary. By pressing the confirmation key, the scroll button is pressed.

In addition, in addition to the cross key (cursor operation key), a configuration in which a scroll key is separately arranged on the remote control is also conceivable. However, this configuration increases the cost of the remote control. Also, the number of keys that can be arranged on the remote control is limited. Thus, a configuration in which the area of each key is reduced and the key is arranged on the remote control is also conceivable, but this configuration has a problem that it is difficult for the user to press the key.

In addition, when the user wants to select a selection target item (for example, a link object) displayed on the display image and operate the content with the cursor, the user operates the direction key of the remote controller to move the cursor to the selection target item. It is necessary to press the enter key located on the remote control in the moved state. In this case, the user needs to perform an operation of pressing the confirmation key on the remote controller while the cursor key is accurately moved to the selection target item by the operation of the direction key.

JP 2001-209495 A

Conventionally, in a video processing apparatus such as a broadcast receiving apparatus, when a certain selection target item is selected using a cursor, a user operates a direction key of a remote controller to move the cursor to the position of the selection target item. When the cursor overlaps with the selection target item, the user needs to press the enter key. In this case, the cursor must be accurately positioned at the position of the selection target item. Further, when the selection target item is confirmed, the user has to press a confirmation key different from the direction key (cursor operation key).

Also, conventionally, for example, when it is necessary to switch images, it is necessary to place a key different from the direction key on the remote controller and switch the image by operating the other key. Conventionally, for example, when scrolling an image, it is necessary to operate a scroll button (key) of a display image by operating a direction key.

That is, conventionally, there has been a problem that the operation of keys for executing a plurality of processes such as image switching and scrolling is complicated.

The present invention has been made to solve such a problem, and an object thereof is to provide a video processing apparatus and the like capable of executing a plurality of processes by simple key operations.

In order to achieve the above object, the video processing apparatus according to one aspect of the present invention is operated by a remote controller that detects the amount of pressing on a key. The video processing device includes: a receiving unit that receives press data indicating the level of press on the key, which is transmitted from the remote controller when a press is applied to the key; and the size of the press indicated by the press data And a control unit that selectively switches a process to be executed by the video processing apparatus from a plurality of predetermined processes.

According to the present invention, the receiving unit receives the pressing data indicating the magnitude of the pressing on the key, which is transmitted from the remote controller when the pressing is applied to the key. The control unit selectively switches a process to be executed by the video processing apparatus from a plurality of predetermined processes according to the magnitude of the press indicated by the press data.

This makes it possible to execute a plurality of processes by a simple key operation of changing the key press.

The objects, features, aspects, and advantages of the present invention will become more apparent from the following detailed description and the accompanying drawings.

Referring to FIG. 1, video processing apparatus 100 includes a communication I / F 4, a processor 3, an audio output I / F 13, a video output I / F 14, and a remote control I / F 16.

The communication I / F 4 includes, for example, a LAN connector and a PHY IC (Physical Layer Integrated Circuit). The communication I / F 4 receives a signal including video content of analog data distributed from the content distribution server 1. The communication I / F 4 converts the received video content into digital data, and transmits the converted video content to the processor 3.

The processor 3 includes a communication processing unit 5, a channel selection processing unit 6, a demultiplexer 7, an audio decoder 8, a video decoder 9, a display processing unit 10, a control unit 11, and an image composition unit 12. .

The control unit 11 performs various processes according to a program (software). The control unit 11 controls the communication processing unit 5, the channel selection processing unit 6, the demultiplexer 7, the audio decoder 8, the video decoder 9, the display processing unit 10, and the like. Further, the control unit 11 performs control for causing the display processing unit 10 to generate an image based on the data received from the communication processing unit 5. The image generated by the display processing unit 10 is an EPG image, a WEB image, a menu image, or the like.

The communication processing unit 5 has a communication function for performing protocol processing corresponding to various communication protocols, communication data format conversion processing, and the like. The communication processing unit 5 communicates with the control unit 11. The communication processing unit 5 transmits data to the control unit 11 as necessary. In addition, the communication processing unit 5 transmits the received video content to the channel selection processing unit 6.

The channel selection processing unit 6 selects (extracts) data (data in which video data and audio data are multiplexed) corresponding to a channel according to a selection instruction received from the control unit 11 from the received video content. The selection instruction is an instruction indicating a channel selected by the user by operating the remote controller 200. The channel selection processing unit 6 receives the selection instruction from the remote controller 200 via the control unit 11.

The demultiplexer 7 extracts video data and audio data from the data selected by the channel selection processing unit 6. That is, the demultiplexer 7 separates the data selected by the channel selection processing unit 6 into video data and audio data. Then, the demultiplexer 7 transmits the video data and the audio data to the video decoder 9 and the audio decoder 8, respectively.

The video decoder 9 converts the received video data into data (analog data or digital data) in a format that can be processed by the monitor 15. Then, the video decoder 9 transmits the converted video data to the image composition unit 12.

The audio decoder 8 converts the received audio data into data (analog data or digital data) in a format that can be processed by the speaker 30. Then, the audio decoder 8 transmits the converted audio data to the audio output I / F 13.

The image composition unit 12 generates a composite image in which the image received from the display processing unit 10 is superimposed (synthesized) on the video (image) indicated by the video data received from the video decoder 9 as necessary. Then, the image composition unit 12 transmits the composite image to the video output I / F 14.

Note that, when it is not necessary to generate a composite image, the image composition unit 12 transmits the video (image) indicated by the video data received from the video decoder 9 to the video output I / F 14. Further, when there is no need to process the video data received from the video decoder 9, the image composition unit 12 transmits the image received from the display processing unit 10 to the video output I / F 14.

The video output I / F 14 has a function of performing D / A conversion and a function of converting received data into data in an HDMI (registered trademark) (High Definition Multimedia Interface) format. The video output I / F 14 has, for example, an RCA terminal and an HDMI terminal not shown.

When the monitor 15 has an analog image display function, the video output I / F 14 converts the image received from the image composition unit 12 into an analog image by D / A conversion. Then, the video output I / F 14 transmits the analog image to the monitor 15. The monitor 15 displays the received analog image.

On the other hand, when the monitor 15 has a digital image display function, the video output I / F 14 converts the image indicated by the received video data into a digital image according to the HDMI format. Then, the video output I / F 14 transmits the digital image to the monitor 15 via the HDMI terminal. The monitor 15 displays the received digital image.

The audio output I / F 13 has an audio D / A converter and an RCA terminal. In the audio output I / F 13, the received audio data is converted into analog data by the D / A converter. Then, the audio output I / F 13 transmits the converted audio data to the speaker 30 via the RCA terminal. The speaker 30 outputs sound based on the received sound data.

As described above, the audio data (signal) is transmitted to the speaker 30 via the audio output I / F 13. The video data (signal) is transmitted to the monitor 15 via the video output I / F 14.

Further, the video processing apparatus 100 communicates with various WEB servers (for example, the content distribution server 1) on the network via the communication I / F 4. In the video processing apparatus 100, the control unit 11 performs control to cause the display processing unit 10 to generate an image based on data received from the WEB server, using a WEB browser.

In this case, the display processing unit 10 generates an image according to the control and displays the image on the monitor 15 via the video output I / F 14. The user can display the WEB image desired by the user on the monitor 15 by operating the remote controller 200.

The remote control I / F 16 has a function of communicating with the remote control 200, details of which will be described later. The remote control I / F 16 is a receiving unit that receives data (information) transmitted from the remote control 200. The remote control I / F 16 transmits data (information) received from the remote control 200 to the control unit 11.

The short-range wireless communication includes communication using infrared rays, communication according to Bluetooth (Bluetooth (registered trademark)), communication using a wireless LAN, and the like.

A plurality of keys 22, a cross key 26, and a confirmation key 25 are arranged on the surface of the remote controller 200. One of a plurality of types of functions is assigned to each of the plurality of keys 22.

The cross key 26 includes pressure-

sensitive keys

23U, 23D, 23L, and 23R. Hereinafter, each of the pressure

sensitive keys

23U, 23D, 23L, and 23R is also simply referred to as a pressure sensitive key 23 or a direction key. The pressure-sensitive key 23 is a pressure-sensitive key (switch) that can detect the amount of pressure applied to the pressure-sensitive key 23. Although details will be described later, the video processing apparatus 100 operates an image displayed on the monitor 15 in accordance with the pressure applied to the pressure-sensitive key 23.

The pressure-sensitive key 23U is an up key (direction key) used to move the cursor upward. The pressure sensitive key 23D is a down key (direction key) used to move the cursor downward. The pressure sensitive key 23L is a left key (direction key) used for moving the cursor to the left. The pressure sensitive key 23R is a right key (direction key) used to move the cursor to the right. That is, each pressure-sensitive key 23 is a key for moving the cursor when the pressure-sensitive key 23 is pressed.

Hereinafter, the pressure

sensitive keys

23U, 23D, 23L, and 23R are also referred to as an up key, a down key, a left key, and a right key, respectively.

The operation unit 17 of the remote controller 200 includes a plurality of keys 22, a plurality of pressure sensitive keys 23 (direction keys), and a confirmation key 25. Each pressure sensitive key 23 includes a pressure sensitive sensor 24.

The pressure sensor 24 may be configured not to be included in the pressure key 23. In the case of this configuration, the pressure sensor 24 is provided in association with each pressure key 23, for example.

In the following, the key code of the direction key is also referred to as a direction key code. The direction key code is, for example, any one of an up key, a down key, a left key, and a right key.

Each pressure sensor 24 is a sensor that can detect the amount of pressure applied to the pressure sensitive key 23 including the pressure sensor 24. That is, the pressure-sensitive key 23 including the pressure-sensitive sensor 24 detects the magnitude of the pressure on the pressure-sensitive key 23 itself. In other words, the remote controller 200 including the pressure sensor 24 detects the amount of pressure on the key (pressure key 23).

When the pressure key 23 is pressed by the user, the pressure sensor 24 outputs press data indicating the magnitude of (applied) the pressure to the pressure key 23. The magnitude of the pressure is expressed by a value in the range from the minimum value “1” to the maximum value “10”, for example. The size of the press is not limited to “1” to “10”, and may be expressed by a value in the range of “1” to “5”, for example.

Further, when the two pressure sensitive keys 23 are pressed at the same time, the pressure sensitive sensor 24 outputs two corresponding pressing data to the two pressure sensitive keys 23, respectively.

When the user presses any of the key 22, the pressure sensitive key 23, and the confirm key 25, the operation unit 17 outputs the key code of the pressed key. The operation unit 17 outputs the key code of the pressure sensitive key 23 and the pressing data of the pressure sensitive key 23 when the pressure sensitive key 23 is pressed. The pressing data is data output from the pressure sensor 24 of the pressure key 23. In addition, when two pressure-sensitive keys 23 (direction keys) are pressed at the same time, the operation unit 17 includes two key codes (direction key codes) and two press data corresponding to the two pressure-sensitive keys 23. Is output.

Here, it is assumed that the video processing apparatus 100 accesses, for example, a designated WEB server on the network and displays a WEB image on the monitor 15. Note that the monitor 15 may not be able to display the entire page of the WEB image due to restrictions on the screen resolution of the monitor 15 or the like. In this case, the video processing apparatus 100 (display processing unit 10) stores the entire page data in a memory in the display processing unit 10, and a part of the WEB image is monitored via the video output I / F 14 on the monitor 15. Control to display on the screen. Hereinafter, the image displayed on the monitor 15 is also referred to as a display image. The display processing unit 10 performs control to display a cursor in the display image displayed on the monitor 15.

When the user wants to further view information linked to the page, the user moves the cursor shown in the display image to, for example, a link object by operating the cross key 26 of the remote controller 200. Then, in a state where the cursor and the link object overlap, the user performs an operation of selecting the link object indicated by the display image by pressing the confirmation key 25. When a link object is selected, the video processing apparatus 100 acquires page data of a link destination of the link object and displays the page on the monitor 15. When the user wants to perform an operation on the display image, such as playing a moving image, the cursor is moved to the play button indicated by the display image by operating the cross key 26, and the play key 25 is pressed to start playing the moving image. Let

When the pressure sensitive key 23 (cross key 26) is pressed, the CPU 19 of the remote controller 200 acquires the key code and the pressing data of the pressed pressure sensitive key 23 from the operation unit 17. Then, the CPU 19 transmits the acquired key code and press data to the transmission circuit 21. The transmission circuit 21 transmits the received key code and press data to the video processing device 100. That is, the transmission circuit 21 is a transmission unit that transmits the pressing data to the video processing device 100 when pressing is applied to the direction key (pressure-sensitive key 23).

For example, when the left key (pressure-sensitive key 23L) is pressed by the user, the remote controller 200 outputs the key code of the left key and the pressing data of the left key. Further, for example, when a portion of the cross key 26 in the diagonally upper right direction is pressed, that is, when the upper key and the right key are pressed at the same time, the operation unit 17 moves upward in accordance with the pressed angle. And the pressure data which shows the magnitude | size of the pressure decomposed | disassembled rightward are output.

Specifically, the operation unit 17 is pressed down with pressing data indicating the level of pressing with respect to the up key (pressure-sensitive key 23U) and pressing data indicating the level of pressing with respect to the right key (pressure-sensitive key 23R). Outputs the key code for the up and right keys. The CPU 19 transmits the key code and press data output from the operation unit 17 to the video processing device 100 via the transmission circuit 21.

In the video processing apparatus 100, the control unit 11 receives a key code and press data transmitted from the remote control 200 via the remote control I / F 16.

Next, in the present embodiment, processing when the direction key (cross key 26), the key 22, etc. are pressed (hereinafter also referred to as key correspondence processing) will be described. The key correspondence process is performed every time the control unit 11 receives one or more key codes.

FIG. 3 is a flowchart of key correspondence processing according to Embodiment 1 of the present invention.

In step S100, the control unit 11 determines whether or not the received key code is a direction key key code (direction key code). If YES in step S100, the process proceeds to step S101. On the other hand, if NO at step S100, the process proceeds to step S130.

Here, it is assumed that the user presses the diagonally upper right portion of the cross key 26 of the remote controller 200. That is, it is assumed that the user simultaneously presses the upper key and the right key of the remote controller 200.

In this case, the remote controller 200 transmits the key code of the up key and the right key and the two pieces of press data respectively corresponding to the up key and the right key to the video processing device 100. That is, the key code and the press data are transmitted from the remote controller 200 to the video processing device 100 when a press is applied to the key (direction key).

Thereby, the remote control I / F 16 receives the key code (direction key code) of the up key and the right key and the two press data. That is, the remote control I / F 16 functions as a receiving unit. The remote control I / F 16 transmits the received upper key and right key key codes (direction key codes) and two pieces of pressing data to the control unit 11.

Thereby, the control unit 11 receives the key code (direction key code) of the up key and the right key and the two press data via the remote control I / F 16. In this case, the process proceeds to step S101.

When the user presses the upper key of the remote controller 200, the remote controller 200 transmits the key code of the upper key and the pressing data corresponding to the upper key to the video processing device 100. As a result, the control unit 11 receives the key code of the up key and the press data corresponding to the up key. That is, the control unit 11 receives one direction key code and one press data. In this case, the process proceeds to step S101.

In step S101, a pressing direction calculation process is performed. In the pressing direction calculation process, the direction (angle) in which the cross key 26 is pressed is calculated. Specifically, when the control unit 11 receives two direction key codes and two press data, the control unit 11 calculates a pressing direction based on the two direction key codes and the two press data.

Here, as an example, it is assumed that the two direction key codes are an upper key code and a right key code. Further, it is assumed that the two pressing data are the pressing data for the up key and the pressing data for the right key. Further, it is assumed that each of the upper key press data and the right key press data indicates “8”. Hereinafter, the coordinate system indicating the x axis and the y axis orthogonal to each other is also referred to as an xy coordinate system.

In this case, the control unit 11 obtains a combined vector of a vector having a size “8” along the + y direction in the xy coordinate system and a vector having a size “8” along the + x direction in the xy coordinate system. Then, the calculated direction of the combined vector is calculated as the pressing direction. In this case, the calculated pressing direction is a direction along the y-axis rotated 45 degrees counterclockwise. Since a method for obtaining a combined vector of two vectors is a well-known method, detailed description will not be given.

When the control unit 11 receives one direction key code and one press data, the control unit 11 calculates a pressing direction based on the one direction key code and the one press data. .

Here, as an example, it is assumed that one direction key code is the key code of the up key. Further, it is assumed that one piece of pressing data indicates “8”. In this case, the control unit 11 calculates the direction of the vector having the size “8” along the + y direction in the xy coordinate system as the pressing direction. In this case, the calculated pressing direction is a direction along the y axis (+ y direction).

In the following, the pressing direction calculated by the pressing direction calculation process is also referred to as a calculated pressing direction.

In step S102, a pressure calculation process is performed. In the press calculation process, the control unit 11 calculates the size of the key press specified by the received key code. Specifically, the control unit 11 calculates the magnitude of the vector corresponding to the calculated pressing direction as the pressing magnitude.

Here, as an example, it is assumed that the vector corresponding to the calculated pressing direction is a combined vector of a vector of size “8” along the + y direction and a vector of size “8” along the + x direction. . In this case, from √ (8 ² +8 ² ) = 11.31, the size of the pressure is calculated as 11.31.

As another example, it is assumed that the vector corresponding to the calculated pressing direction is a vector of size “8” along the + y direction. In this case, the control unit 11 acquires (calculates) the magnitude of the press as “8”. Hereinafter, the magnitude of the pressure calculated or acquired by the pressure calculation process is also referred to as a pressure A.

In step S110, it is determined whether or not the pressure A is greater than a predetermined threshold value α. The threshold value α is, for example, a value that is 50 to 70% of the maximum value indicated by the pressing data. As an example, the threshold α is assumed to be “6”.

If YES in step S110, the cursor movement process described later is not performed, and the process proceeds to step S121. On the other hand, if NO at step S110, the process proceeds to step S122.

In step S121, scroll processing for scrolling the image displayed on the monitor 15 is performed. In the scroll process, the display processing unit 10 performs a process for scrolling the display image in the calculation pressing direction. More specifically, the display processing unit 10 scrolls the display image by sequentially reading out the image data in the calculated pressing direction from the image memory and displaying the image data on the monitor 15.

FIG. 4 is a diagram for explaining the scrolling process. In FIG. 4, an image G300 is an example of an image stored in the image memory of the display processing unit 10. In the image G300, for example, a link object LK1 is arranged. The link object LK1 is, for example, the aforementioned hyperlink image or hyperlink text. The link object LK1 is a selection target item. The image G100 is a part of the image G300. The image G100 is a display image displayed on the monitor 15. Note that the image G100 shows the cursor C1.

In this case, in the scroll process of step S121, the display processing unit 10 performs a moving image display process.

In the moving image display process, the display processing unit 10 reads an image in the outline when the outline (frame) of the image G100 in FIG. 4 is moved by a predetermined pixel in the calculation pressing direction. Then, the display processing unit 10 controls the image composition unit 12 to display the read image on the monitor 15.

The display processing unit 10 scrolls the display image in the calculation pressing direction by repeatedly performing the moving image display process. The calculation pressing direction is, for example, the direction d1. And this key corresponding | compatible process is complete | finished.

Referring to FIG. 3 again, if NO in step S110, that is, if pressure A is equal to or less than threshold value α, the process proceeds to step S122.

In step S122, cursor movement processing for moving the cursor is performed. In the cursor movement process, the display processing unit 10 uses the image composition unit 12 to perform a process of moving the cursor C1 in the calculation pressing direction by the amount of pixels corresponding to the pressure A. The pixel corresponding to the pressure A is, for example, a pixel having a value obtained by the pressure A × 2. The process of moving the cursor C1 is a well-known technique and will not be described in detail. And this key corresponding | compatible process is complete | finished.

Note that, by the processing in step S122, for example, the cursor can be moved in the direction of the link object desired by the user.

If the direction key is kept pressed with a pressure weaker than the threshold value α, step S122 is repeated. In this case, the cursor can be moved over a period during which the direction key is pressed.

Through the processing in steps S110, S121, and S122 described above, the video processing apparatus 100 executes cursor movement processing or scroll processing according to the comparison result between the magnitude of the pressure A and the threshold value α. More specifically, the video processing apparatus 100 executes a cursor movement process when the magnitude of the pressure A is equal to or less than the threshold value α. Further, the video processing device 100 executes scroll processing when the magnitude of the pressure A is larger than the threshold value α.

In other words, a scroll process or a cursor movement process is performed depending on whether or not the pressure A is greater than the threshold value α. That is, the process executed by the video processing apparatus 100 can be selectively switched from the scroll process and the cursor movement process by a single operation on the cross key 26. The scroll process and the cursor movement process are processes using the cursor, that is, processes related to the cursor.

That is, the control unit 11 selectively switches the process executed by the video processing apparatus 100 from a plurality of predetermined processes according to the magnitude of the press indicated by the press data. That is, the video processing apparatus 100 selectively switches a process to be executed from a plurality of predetermined processes according to the amount of pressure on the key (pressure-sensitive key 23). The plurality of processes include a cursor movement process and a scroll process. That is, all of the plurality of processes are processes using a cursor.

As shown in FIG. 4, the user strongly presses the cross key 26 (direction key) with a pressure larger than the threshold value in a state where the target (operation target) link object LK1 is not displayed on the monitor 15. Suppose. Thereby, a display image can be scrolled. Further, when the link object LK1 appears on the display image by scrolling the display image, it is possible to switch to an operation of moving the cursor by weakening the pressing.

Referring to FIG. 3 again, if NO in step S100, the process in step S130 is performed.

In step S130, key correspondence processing is performed. In the key correspondence processing, processing assigned to the key specified by the received key code is performed. And this key corresponding | compatible process is complete | finished.

As described above, in the present embodiment, the remote control I / F 16 (reception unit) transmits the key (pressure sensitive key 23) transmitted from the remote control 200 when a key (pressure sensitive key 23) is pressed. The pressure data indicating the magnitude of the pressure for the above is received. The control unit 11 selectively switches the process executed by the video processing apparatus 100 from a plurality of predetermined processes according to the magnitude of the press indicated by the press data. Thus, a plurality of processes can be executed by a simple key operation of changing the key press.

In addition, conventionally, for example, when scrolling an image, it is necessary to operate a key for scrolling a display image by operating a direction key of a remote controller. When a display image is operated with an apparatus using such a remote controller, there is a problem that operability is extremely poor.

On the other hand, in the present embodiment, the user can move the cursor key and scroll the image by operating the same key. That is, the movement of the cursor and the scrolling of the image in the same direction can be performed by operating the same key.

In addition, as described with reference to FIG. 4, the display image is displayed when the user strongly presses the cross key 26 (direction key) with a pressure larger than the threshold value in a state where the link object LK1 is not displayed on the monitor 15. Can be scrolled. Further, when the link object LK1 appears on the display image by scrolling the display image, it is possible to switch to an operation of moving the cursor by weakening the pressing.

Therefore, in the present embodiment, the user can perform a switching operation between the cursor movement in the calculation pressing direction and the image scrolling without removing the finger from the direction key (pressure-sensitive key 23). Therefore, the user can quickly browse the entire information displayed on the image with a simple operation. As a result, operability and convenience can be significantly improved.

Also, according to the present embodiment, switching between the cursor movement process and the scroll process can be performed without releasing the finger with respect to the same key. Therefore, it is possible to shorten the time for accessing an image or a selection target item (link object) that is not currently displayed by scroll processing.

Further, according to the present embodiment, a plurality of types of processing corresponding to the magnitude of the pressure applied to the pressure sensitive key 23 are assigned to each direction key (pressure sensitive key 23). Thereby, the operativity can be improved.

In this embodiment, an example of cursor movement and image scroll processing in the WEB image indicated by the WEB browser is shown, but the present invention is not limited to this. The configuration of this embodiment can be applied to an image in which a cursor is displayed and can be scrolled. The scrollable image is, for example, a selection image for selecting a program guide.

In step S121 of FIG. 3, other processing may be performed instead of the scroll processing. The other process is, for example, a process of switching the image displayed on the monitor 15 to another image. In this case, the operation time for other processing such as image switching can be shortened. As a result, the time for the user to access the target information can be shortened.

<Embodiment 2>
Next, the structure of this Embodiment is demonstrated based on figures. The video processing system according to the present embodiment is the video processing system 1000 of FIG.

Here, as an example, it is assumed that the video processing apparatus 100 accesses a specified WEB site on the network and displays a WEB image on the monitor 15. In this situation, the user wants to see information linked to the page (WEB image). In this case, the user operates the direction key (pressure-sensitive key 23) of the remote controller 200, moves the cursor, and performs an operation of selecting the link object (selection target item) indicated by the display image.

For example, assume that the user presses the cross key 26 (pressure-sensitive key 23) arranged on the remote controller 200. In this case, the CPU 19 of the remote controller 200 acquires the key code and press data of the pressed key. Then, the CPU 19 transmits the key code (direction key code) and pressed data of the pressed direction key to the video processing apparatus 100 via the transmission circuit 21.

For example, when the left key is pressed, the remote controller 200 outputs the key code and press data of the left key. The press data is data output from the pressure sensor 24 of the left key (pressure key 23). Further, when a portion of the cross key 26 diagonally right above is pressed, that is, when the up key and the right key are pressed at the same time, the operation unit 17 moves upward and right according to the pressed angle. Press data indicating the size of each decomposed press is output.

Next, in the present embodiment, processing when the direction key (cross key 26), key 22, etc. are pressed (hereinafter also referred to as key correspondence processing A) will be described. The key handling process A is performed every time the control unit 11 receives one or more key codes.

FIG. 5 is a flowchart of the key handling process A according to Embodiment 2 of the present invention. In FIG. 5, the process with the same step number as the step number in FIG. 3 is performed in the same way as the process described in the first embodiment, and therefore detailed description will not be repeated.

Here, it is assumed that the monitor 15 displays a WEB image on which the link object LK1 of FIG. 4 is arranged as a display image. As described above, the link object LK1 is a selection target item. Further, it is assumed that a cursor C1 is displayed on the WEB image.

Hereinafter, the points different from the first embodiment will be mainly described. In steps S100, S101, S102, S110, S122, and S130, processing similar to that in the first embodiment is performed.

If YES in step S110, the process proceeds to step S111A.

In step S111A, it is determined whether or not the cursor overlaps the selection target item. Specifically, the control unit 11 determines whether or not the coordinates of the cursor C1 are within the coordinates where the selection target item is arranged.

The coordinates of the cursor C1 are the coordinates of the tip of the arrow indicating the cursor C1. The coordinates where the selection target item is arranged are all the coordinates included in the outline of the selection target item. Here, it is assumed that the selection target item is the link object LK1 in FIG. In this case, in step S111A, the control unit 11 determines whether or not the coordinates of the cursor C1 are within the coordinates where the link object LK1 is arranged.

If YES in step S111A, the process proceeds to step S121A. If YES in step S111A, the selection target item (for example, link object LK1) is selected. On the other hand, if NO at step S111A, the process proceeds to step S122.

In step S121A, a confirmation process is performed. The confirmation process is a process for confirming the process corresponding to the selection target item selected by the cursor and executing the confirmed process. The selection target item is an item to be selected.

That is, the confirmation process is a process using a cursor. Specifically, the control unit 11 determines a process associated with the selection target item selected by the cursor C1 and executes the process.

Here, it is assumed that the selection target item is the link object LK1. Further, the link object LK1 is assumed to be a hyperlink image, for example. Further, it is assumed that the link object LK1 is associated with a process for displaying the WEB page of the designated URL.

In this case, the control unit 11 uses the communication I / F 4 to perform processing for performing communication in order to obtain the WEB page of the specified URL on the Internet. And the control part 11 controls the display process part 10 grade | etc., So that the acquired WEB page may be displayed on the monitor 15. FIG.

As another example, it is assumed that the selection target item is an item that is not linked (non-link object). For example, it is assumed that a process for switching an image displayed on the monitor 15 is associated with the selection target item. In this case, in the confirmation process, the control unit 11 performs a process for switching images.

Through the processes in steps S110, S111A, S121A, and S122, the video processing apparatus 100 executes the cursor movement process or the confirmation process according to the comparison result between the magnitude of the pressure A and the predetermined threshold value α. That is, the control unit 11 selectively switches the process executed by the video processing apparatus 100 from a plurality of predetermined processes according to the magnitude of the press indicated by the press data. The plurality of processes include a cursor movement process and a confirmation process.

Specifically, the video processing apparatus 100 executes a cursor movement process when the magnitude of the pressure A is equal to or less than the threshold value α. In addition, when the magnitude of the pressure A is larger than the threshold value α, the video processing apparatus 100 executes a confirmation process.

According to the present embodiment as described above, the user can perform the cursor key movement and the confirmation process by operating the same key. In addition, the user can perform a switching operation between the cursor movement in the calculation pressing direction and the confirmation process without releasing the finger from the direction key (pressure-sensitive key 23). Therefore, the user can quickly browse the entire information displayed on the image with a simple operation. As a result, operability and convenience can be significantly improved.

Also, according to the present embodiment, switching between the cursor movement process and the confirmation process can be performed without releasing the finger with respect to the same key. Therefore, it is possible to shorten the time from the start of the cursor movement to the end of the confirmation process.

<Embodiment 3>
Next, the structure of this Embodiment is demonstrated based on figures. The video processing system according to the present embodiment is the video processing system 1000 of FIG.

In the present embodiment, it is assumed that the video processing apparatus 100 accesses the WEB site and displays the WEB image on the monitor 15 as in the second embodiment. In this situation, the user wants to see information linked to the page (WEB image). In this case, the user operates the direction key (pressure-sensitive key 23) of the remote controller 200, moves the cursor, and performs an operation of selecting the link object indicated by the display image.

The processing when the left key is pressed or when the part of the cross key 26 in the upper right direction is pressed is the same as that in the second embodiment, and thus detailed description will not be repeated.

Next, processing in the case where the direction key (cross key 26), the key 22, etc. are pressed (hereinafter also referred to as key correspondence processing B) in the present embodiment will be described. The key correspondence process B is performed every time the control unit 11 receives one or more key codes. That is, the key handling process B is performed each time a key is pressed on the remote controller 200.

FIG. 6 is a flowchart of the key correspondence process B according to the third embodiment of the present invention. In FIG. 6, the process with the same step number as the step number of FIG.

Here, as an example, it is assumed that the monitor 15 displays the image G200 of FIG. 7 as a display image.

FIG. 7 is a diagram for explaining the movement of the cursor according to the third embodiment of the present invention. FIG. 7A shows an image G200 as an example. As shown in FIG. 7A, link objects LA1, LB1, LC1, and LD1 and a cursor C1 are arranged in the image G200. Each of the link objects LA1, LB1, LC1, and LD1 is a selection target item (object) similar to the link object LK1 described above. That is, the image G200 displayed on the monitor 15 shows a plurality of selection target items. Hereinafter, each of the link objects LA1, LB1, LC1, and LD1 is also simply referred to as a link object L.

Hereinafter, with reference to FIG. 6 and FIG. 7 (a), the description will be focused on differences from the first embodiment. In steps S100, S101, S102, S110, S122, and S130, processing similar to that in the first embodiment is performed.

If NO in step S110, that is, if the magnitude of the pressure A is equal to or less than the threshold value α, the process proceeds to step S122.

In step S122, processing similar to that in the first embodiment is performed. That is, when the remote control I / F 16 as the receiving unit receives the pressing data, the display processing unit 10 performs a process for moving the cursor based on the received pressing data. Thereby, the cursor C1 moves.

In step S123B, an item selection process is performed. Although details will be described later in the item selection process, the control unit 11 selects any one of a plurality of selection target items based on the coordinates of the cursor C1, the coordinates of each selection target item, and the direction of travel of the cursor C1. .

Here, it is assumed that the selection target item is a link object L. The coordinates of the cursor C1 are the coordinates of the tip of the arrow indicating the cursor C1. Further, the coordinates of each selection target item (link object L) are, for example, the coordinates of the upper left corner of the link object L. Hereinafter, the selection target item selected by the item selection process is also referred to as a selection item.

Suppose that the coordinates of the link object LA1 in FIG. 7A are (x1, y1). Further, it is assumed that the coordinates of the link object LB1 are (x2, y2). Further, it is assumed that the coordinates of the link object LC1 are (x3, y3). The coordinates of the link object LD1 are (x4, y4).

Note that the coordinates of each link object L are not limited to the coordinates of the upper left corner of the link object L. For example, the coordinates of each link object L may be the coordinates of the upper right corner of the object L.

The details of how to select items to be selected will be described later.

In step S124B, highlighting processing is performed. The highlighting process is a process for highlighting selected items. Specifically, the control unit 11 controls the display processing unit 10 so that the selected item is highlighted with respect to a plurality of items excluding the selected item. That is, the user can know which item is selected from the plurality of items.

Here, it is assumed that the selection item is, for example, the link object LA1 in FIG. In this case, the plurality of items excluding the selection items are link objects LB1, LC1, and LD1.

An example of the highlighting process is a process of changing (or inverting) the color of the character indicated by the selection item. Another example of the highlighting process is a process of blinking and displaying the entire selection item (link object L). After the process of step S124B, the key association process B ends.

The key handling process B is performed each time a direction key or key is operated. That is, the key correspondence process B is performed every time the cursor moves.

Step S122 is performed when the pressure A obtained based on the pressure data is equal to or less than the threshold value α. Therefore, each time the cursor C1 moves in steps S122 and S123B, the item selection process in step S123B is performed. In addition, the selected item (link destination candidate) changes depending on the position of the cursor and the direction of movement of the cursor through steps S123B and S124B.

Next, processing in the case of YES in step S110, that is, processing when the magnitude of the pressure A is larger than the threshold value α will be described. In the case of YES at step S110, step S120B is performed.

In step S120B, an item selection process is performed. Since the item selection process is the same as the process of step S123B, detailed description will not be repeated.

In step S121B, an instantaneous movement process is performed. The instantaneous movement process is a process for instantaneously moving the cursor to the position of the selection target item (selected item) selected in step S120B.

Specifically, in the instantaneous movement process, the control unit 11 controls the display processing unit 10 so that the cursor C1 instantaneously moves to the selected item. Here, it is assumed that the selection item is, for example, the link object LA1. In this case, the cursor C1 is displayed by being superimposed on the link object LA1, which is a selection item, by the instantaneous movement process, as in the image G200A of FIG. And this key corresponding | compatible process B is complete | finished.

Through the processes in steps S110, S120B, S121B, and S122, the video processing apparatus 100 executes the cursor movement process or the instantaneous movement process according to the comparison result between the magnitude of the pressure A and the predetermined threshold value α. That is, the control unit 11 selectively switches the process executed by the video processing apparatus 100 from a plurality of predetermined processes according to the magnitude of the press indicated by the press data. The plurality of processes include a cursor movement process and an instantaneous movement process.

Specifically, the video processing apparatus 100 executes a cursor movement process when the magnitude of the pressure A is equal to or less than the threshold value α. In addition, when the magnitude of the pressure A is larger than the threshold value α, the video processing device 100 executes an instantaneous movement process.

Further, through the processing of steps S110, S120B, S121B, S123B, and S124B, the video processing apparatus 100 executes the instantaneous movement process or the highlight display process according to the comparison result between the magnitude of the pressure A and a predetermined threshold value α. To do. That is, the control unit 11 selectively switches the process executed by the video processing apparatus 100 from a plurality of predetermined processes according to the magnitude of the press indicated by the press data. The plurality of processes include an instantaneous movement process and a highlighting process. That is, some of the plurality of processes are processes using a cursor.

Specifically, the video processing apparatus 100 executes the highlighting process when the magnitude of the pressure A is equal to or less than the threshold value α. In addition, when the magnitude of the pressure A is larger than the threshold value α, the video processing device 100 executes an instantaneous movement process.

In the key correspondence process B, all processes shown in FIG. 6 need not be performed. In the key correspondence process B, for example, the process of step S122 may not be performed. In the key correspondence process B, for example, the processes of steps S123B and S124B do not have to be performed.

Next, a method for selecting an item (link object L) in the item selection process will be described in detail.

Here, it is assumed that the selection condition of the item (link object) to be selected is the following condition A. The condition A is a condition that the closest item (link object) is selected from the current position (coordinates) of the cursor C1. In this case, the control unit 11 calculates a linear distance from the coordinates (position) of the current cursor C1 to the coordinates (position) of each link object L. Since the number of link objects L is 4, four linear distances are calculated.

And the control part 11 selects the link object L corresponding to the shortest linear distance among four linear distances as a link destination candidate.

Note that, in the condition A, when the user performs an operation of moving the cursor, the link object L existing in the direction not intended by the user is highlighted (focused) or the link object L existing in the unintended direction is displayed. The cursor may move instantaneously.

Therefore, in the item selection process in steps S123B and S120B, the control unit 11 selects items (link destination candidates) in consideration of the moving direction of the cursor C1 in addition to the coordinates of the cursor C1 and the coordinates of the link object L.

Specifically, as shown in FIG. 7A, in the state where the monitor 15 is displaying an image G200 showing a plurality of link objects L, the user operates the direction key for moving the cursor C1. Suppose you are going. Also, the calculated pressing direction calculated in step S101 is assumed to be the direction d2.

Hereinafter, the axis along the direction d2 is also referred to as a pressing direction axis. Hereinafter, the coordinates of the cursor C1 are also referred to as cursor coordinates. Further, in the following, the pressing direction axis rotated clockwise by an angle θ / 2 with the cursor coordinates as the center of rotation is referred to as an axis A1. Further, in the following, the pressing direction axis rotated counterclockwise by the angle θ / 2 with the cursor coordinates as the center of rotation is referred to as axis A2. In the following, a region between the axis A1 and the axis A2 is also referred to as a selection target region.

In this case, in the item selection process, the control unit 11 selects the link object L existing in the selection target area corresponding to the calculated pressing direction calculated in step S101 as a link destination candidate. That is, the control unit 11 selects the link object L within the range of the angle θ as the link destination candidate with respect to the calculated pressing direction calculated in step S101. In the example of FIG. 7A, the selected link objects L are the link objects LA1 and LD1.

When there are a plurality of selected link objects L, the link object L closest to the cursor C1 is selected as a link destination candidate based on the coordinates (position) of the cursor C1 and the coordinates of each link object L. Is done.

Specifically, the control unit 11 selects the link object L arranged at the coordinate closest to the cursor coordinate among the selected link objects L as the link destination candidate. In the example of FIG. 7A, the control unit 11 selects the link object LA1 as the link destination candidate from the link objects LA1 and LD1.

As described above, one link object L is selected in the item selection process.

As described above, according to the present embodiment, when the user operates the direction key to move the cursor, the selected (selected) link object L (link destination candidate) is highlighted (focused). The Thereby, the user can know the link candidate (link object L) currently selected (recognized). If the link destination candidate (link object L) is a desired link, the user can instantly move the cursor to the link destination candidate (link object L) by pressing the direction key strongly.

In addition, when the desired link object is different from the highlighted link object L, the user can continue to press the direction key weakly to move the cursor closer to the desired link object L.

Therefore, according to the present embodiment, the user can select the link object L (item) only by moving the cursor to the vicinity of the desired link object L. Therefore, it is not necessary to match the position of the cursor to the position of the link object L accurately. Therefore, the cursor can be operated easily and quickly.

Also, according to the present embodiment, when a desired selection target item is accessed by moving the cursor, it is not necessary to accurately align the cursor with the selection target item. Therefore, it is possible to shorten the time until the cursor is moved to the selection target item.

In the present embodiment, the example of the process of moving the cursor to the link object L in the WEB image indicated by the WEB browser is shown, but the present invention is not limited to this. The configuration of the present embodiment can be widely applied to other scenes where a selection target item (for example, a non-link object) is selected using a cursor.
