  Here, a method for measuring the position of the pointer on the television screen by the laser light irradiated on the television screen in the present embodiment will be described.

  As a method of measuring the position of the pointer by the laser light irradiated on the television screen, a method disclosed in Japanese Patent Laid-Open No. 8-117447 can be applied.

  According to the method disclosed in this publication, raster scanning of a white screen that is “100% white” for position measurement is started simultaneously with a trigger.

  The light receiving unit sets the light receiving area in the vicinity of a pointer by laser light (corresponding to the “position aimed at with the gun” in the above publication), detects the light of the raster scan, and serves as pointer position information. calculate. A specific calculation method is described in the above publication, but the principle is described as follows.

That is, assuming that one horizontal period is “h [sec]”, the trigger moment is “0 [sec]”, and the time until the light of the raster scanning is detected by the light receiving unit is “t [sec]”,
t = h * p + q (Formula 1)
It becomes. Here, “p” is an arbitrary integer, and “q” is an arbitrary natural number.

When the vertical length of the TV screen is “HY [m]” and the number of scanning lines in one field (or frame) is “S [lines]”, the distance “D [m]” between the scanning lines is
D = HY / S (Formula 2)
It becomes. Here, since “p” represents the number of scanning lines from the start point of raster scanning to the pointer, if the vertical position of the pointer is “y1”,
y1 = p * D (Formula 3)
It becomes.

Similarly, if the horizontal length of the TV screen is “HX” and the horizontal position of the pointer is “x1”,
x1 = (q / h) * HX (Formula 4)
It becomes.

  The horizontal and vertical positions (x1, y1) of the pointer can be calculated from the above formula.

  This is shown in FIG.

  In the figure, the starting point of raster scanning at the upper left of the television screen is set to “0”, and the x axis is taken to the right and the y axis is taken to the lower side. Reference numeral 601 denotes a light receiving region of the light receiving unit. Here, in order to simplify the description, the light receiving area and the position of the pointer are matched. That is, the coordinates (x1, y1) of the light receiving area are used as the coordinates of the pointer.

  Next, the operation in this embodiment will be described.

  FIG. 7 is a flowchart showing an operation procedure in the present embodiment.

  With reference to the figure, first, the user operates the menu display button of the remote controller to display the menu screen on the television screen (step S1).

  If it does so, the remote control command which displays a menu from the infrared light emission part of a remote control will be transmitted with respect to a television receiver (step S2).

  The television receiver that has received the remote control command (step S3) displays a menu display on the television screen according to the command (step S4).

  The user operates the laser emission button of the remote controller to emit laser light (step S5), and irradiates the laser beam at the position where the desired function is displayed in the menu display displayed on the television receiver. (Step S6).

  When the user operates a determination button on the remote controller when a desired function is determined (step S7), a command for displaying a position measurement screen is transmitted to the television receiver (step S8).

  The television receiver that has received this remote control command (step S9) displays a position measurement screen (step S10).

In the remote controller, the light of the position measurement screen is received by the light receiving unit (step S11), and the position of the laser light pointer on the television screen is calculated by the control unit (step S12). (Strictly speaking, it is not “the position of the pointer” but “the position of the light receiving area” of the light receiving unit provided in the vicinity of the position of the pointer.)
The calculated position information of the laser light pointer is transmitted as a remote control command from the infrared light emitting unit of the remote control to the television receiver (step S13).

  The television receiver that has received the remote control command (step S14) specifies the function of the menu display displayed on the TV screen from the position information (step S15), and executes the specified function (step S16). ).

  Further, an operation procedure as shown in FIG. 8 may be used.

  FIG. 8 adds a procedure (step S8-2) for stopping the emission of laser light after transmitting a command for displaying a position measurement screen to the television receiver (step S8). It is a thing.

  A pointer by laser light is irradiated near the light receiving area of the light receiving unit. Therefore, there is pointer light in addition to light from the position measurement screen when performing position measurement.

  When receiving the light of the position measurement screen, the light of the pointer is extinguished by stopping the emission of the laser light, and the light receiving accuracy of the light receiving unit can be improved. Here, even if the pointer is deleted, it is after the operation is determined (step S7), so there is no inconvenience for the user.

Further, by operating the determination button on the remote controller (step S7), the emission of the laser beam is stopped, so that the user does not need to separately stop the emission of the laser beam, thereby preventing the user from forgetting to turn off the laser beam. be able to.
(2) Embodiment 2 (when the display device is a liquid crystal panel or the like)
FIG. 9 is a configuration block diagram of the television receiver in the present embodiment. In the figure, the same components as those in FIG.

  In FIG. 9, reference numeral 907 denotes a liquid crystal panel (hereinafter referred to as an LCD panel) as a display device, reference numeral 908 denotes a driver controller for controlling the LCD panel 907, reference numeral 910 denotes a source driver controlled by the driver controller 908, Reference numeral 911 denotes a gate driver controlled by the driver controller 908.

  In the case of an LCD panel, unlike a CRT, video display by raster scan is not performed.

  In the LCD panel 907, signals for one scanning line are accumulated in the source driver 910, and signals for one scanning line are transferred to the LCD panel at a time under the control of the gate driver 911.

  For this reason, the method disclosed in Japanese Patent Laid-Open No. 8-117447 can measure the position in the vertical direction, but cannot measure the position in the horizontal direction.

  Therefore, in this embodiment, the position of the pointer is measured by the following method.

  In the first embodiment, a white screen of “100% white” is used as the position measurement screen. In the present embodiment, a so-called “ramp waveform” screen is used instead of the white screen.

  This “ramp waveform” is shown in FIG.

In FIG. 10, as an example, the left end of the TV screen (that is, the left end of the LCD panel) is set to a luminance level of “100%”, and the luminance level decreases linearly toward the right of the TV screen. At the right end of the LCD panel, the luminance level is “25%”. (Conversely, the lamp waveform may be such that the luminance level decreases linearly as it goes to the left of the TV screen, and it is not always necessary that the luminance level be 100% or 25%.)
When such a ramp waveform is used as the position measurement screen, the horizontal position of the pointer can be calculated from the difference in luminance level.

That is, assuming that the horizontal length of the LCD panel is “HX”, the luminance level at the left end of the LCD panel is “A1”, and the luminance level at the right end of the LCD panel is “A0”, the luminance level “AMP” of the lamp waveform is ,
AMP = ((A0−A1) / HX) · X + A1 (Formula 5)
It becomes.

Therefore, when the luminance level is “Ax1”, the horizontal position “x1” is
x1 = (Ax1-A1) / ((A0-A1) / HX) (Expression 6)
It becomes.

  The reason why the luminance level at the right end of the LCD panel is not set to “0%” is that if it is set to “0%”, the light from the position measurement screen cannot be detected by the light receiving unit of the remote controller.

  As described above, in the method for detecting the position of the pointer in the present embodiment, the vertical position is detected until the light from the position measurement screen is detected by the light receiving unit provided in the remote controller, as in the first embodiment. The horizontal position is calculated from the intensity (luminance level) of the light when the light from the position measurement screen is detected.

  The operation procedure in this embodiment is the same as the procedure shown in FIGS.
