JP 2005-164930 A

  However, in the projector setting system described above, the operation setting of the projector itself can be performed according to the installation location, but control of the environment of the installation location is not considered. In general, when a projector is used, it is greatly affected by the environment such as the illumination of the installation location, the brightness of outside light, or the noise of air conditioning. For this reason, when projecting an image with a projector, turn off the illumination (adjust the brightness of the illumination), close the curtain, or stop the air conditioning (or switch to silent operation). The environment setting (peripheral device operation setting) must be performed by the user, which is very time-consuming and troublesome.

  SUMMARY An advantage of some aspects of the invention is that it provides a display device and a projector that can easily set the environment of the installation location of the apparatus to a suitable environment.

  The display device of the present invention includes a remote control signal receiving means for receiving a remote control signal for controlling a peripheral device to be controlled, a remote control signal learning means for learning the received remote control signal, and a learned remote control signal. Remote control signal transmission means for transmitting to the peripheral device as the reception destination at a predetermined timing.

  According to this configuration, the operation of the peripheral device can be controlled by the display device. For example, it is possible to control the operation of peripheral devices such as lighting devices, electric curtains, or air conditioners in the place where the display device is installed, and make the environment for using the display device a suitable environment without human intervention. This can greatly reduce the burden on the user. In addition, remote control signals for controlling peripheral devices can be learned, and peripheral devices can be controlled using the learned signals, so there is no need for special functions on the peripheral device side, and existing devices can be used as they are. Can be realized at low cost.

  In the display device of the present invention, it is preferable that the predetermined timing is when the display device is turned on or off.

  According to this configuration, since the peripheral device can be controlled in accordance with an operation that is always executed when using the display device such as power-on or power-off, for example, a new operation for controlling the peripheral device to the user It is possible to set the environment of the installation location without imposing a burden on the user.

  In the display device of the present invention, the remote control signal learning means includes a first learning means for learning a remote control signal to be transmitted when the power is turned on, and a second learning means for learning the remote control signal to be transmitted when the power is turned off. The remote control signal transmitting means preferably transmits the remote control signal learned by the first learning means when the power is turned on, and transmits the remote control signal learned by the second learning means when the power is turned off.

  According to this configuration, the peripheral device can be controlled when the power is turned off and when the power is turned on, which is convenient.

  A projector according to the present invention is characterized by including each unit in the display device described above.

  According to this configuration, it is possible to provide a projector that can control the operation of the peripheral device at the installation location and set the environment suitable for image projection.

It is a block diagram which shows the control structure of the projector which concerns on one Embodiment of this invention. It is a flowchart explaining the process sequence which learns a remote control signal. It is a flowchart explaining the starting process of a projector.

  Hereinafter, a display device according to an embodiment of the present invention will be described with reference to the accompanying drawings. The display device of the present embodiment can set the environment of the installation location of the device to an environment suitable for use of the device. In the present embodiment, a projector will be described as an example of the display device.

  FIG. 1 is a block diagram illustrating a control configuration of the projector 1. As shown in the figure, the projector 1 includes a signal acquisition unit 11, a video signal processing unit 12, a remote control light receiver 13, an operation unit 14, a display unit 15, a remote control irradiation unit 16, a projection optical unit 17, and a control unit 18. I have.

  The signal acquisition unit 11 acquires image data from an external device 51 such as a personal computer or a video recorder. Note that image data or the like may be acquired from an external storage medium (not shown) instead of the external device 51.

  The video signal processing unit 12 performs predetermined image processing on the image data acquired by the signal acquisition unit 11 based on an image processing program in the ROM 22 described later.

  The remote control light receiver 13 receives a remote control signal (operation signal (infrared signal)) from the remote control 41 operated by the user. The remote controller 41 includes a remote controller 42 for remotely operating the main body of the projector 1 and peripheral devices that affect the projection environment of the projector 1 (for example, an air conditioner, a lighting device, an acoustic device, an electric curtain, a screen SC, etc. ) Is remotely controlled. That is, the remote control light receiver 13 can receive a remote control signal for operating (controlling) peripheral devices in addition to a remote control signal for operating (controlling) the projector 1 main body.

  The operation unit 14 is provided in the main body of the projector 1 and has a button group for performing various operations. The button group includes a power button for switching on / off the power and a remote control learning button for learning a remote control signal from the peripheral device remote controller 43 received by the remote control light receiver 13.

  In remote control signal learning by operating the remote control learning button, a remote control signal for irradiating the peripheral device when the projector 1 is powered on is distinguished from a remote control signal for irradiating the peripheral device when the projector 1 is powered off. Can learn. Specifically, a remote control learning menu is displayed by pressing the remote control learning button, and “power-on learning” and “power-off learning” can be selected from the menu. When the user selects “learning for power-on”, a remote control signal received from the peripheral device remote controller 43 is learned as being emitted when the projector 1 is powered on. On the other hand, when the user selects “learning for power off”, the remote control signal received from the peripheral device remote control 43 is learned to be emitted when the projector 1 is powered off thereafter.

  The “remote control signal learning means” in the claims refers to a remote control signal learning function by operating a remote control learning button. The “first learning means” in the claims refers to a remote control signal learning function when “power-on learning” is selected, and the “second learning means” is “power-off learning”. This refers to the remote control signal learning function when selected.

  The main body remote controller 42 is also provided with the same buttons as those of the operation unit 14. That is, the power on / off switching operation, the remote control signal learning operation, and the like can also be performed from the main body remote control 42.

  The remote control irradiation unit 16 irradiates a remote control signal toward the outside of the projector 1. The remote control signal to be irradiated is a remote control signal (a remote control signal stored in a later-described flash ROM 24) learned by operating the remote control learning button, and this remote control signal is applied to irradiation windows (on the four sides of the projector 1). Irradiate from (not shown). That is, the remote control signal can be irradiated to the periphery of the projector 1 (as a result, to peripheral devices in the vicinity of the projector 1).

  The display unit 15 is configured by a liquid crystal display or the like, and displays selection candidates accompanying various operations by the operation unit 14 and displays processing results corresponding to the various operations (that processing has been completed normally or processing has failed). Display).

  The projection optical unit 17 is for projecting an image on the screen SC, and includes a light source lamp 31 (light source), a liquid crystal light valve 32, a projection lens 33, a lamp driving unit 34, and a light valve driving unit 35. ing.

  As the light source lamp 31, a halogen lamp, a metal halide lamp, or a high-pressure mercury lamp can be applied. Further, a solid light source such as a laser or LED may be used in place of the light source lamp 31. The liquid crystal light valve 32 is constituted by a liquid crystal panel or the like in which liquid crystal is sealed between a pair of transparent substrates, and a transparent electrode capable of applying a driving voltage to each liquid crystal region is provided on the inner surface of each transparent substrate. Pixels are formed in a matrix. The lamp driving unit 34 turns on the light source lamp 31 based on a lighting command from the control unit 18. The light valve driving unit 35 sets the light transmittance of each pixel by applying a driving voltage corresponding to the image data to each pixel of the liquid crystal light valve 32.

  With the above configuration, in the projection optical unit 17, the illumination light emitted from the light source lamp 31 is modulated by passing through the liquid crystal light valve 32. The modulated image light is combined for each pixel by a light combining optical system (not shown) (such as a dichroic prism) and projected onto the screen SC by the projection lens 33.

  The control unit 18 includes a CPU (Central Processing Unit) 21, a ROM (Read Only Memory) 22, a RAM (Random Access Memory) 23, and a flash ROM 24. The CPU 21 is a central processing unit that performs various arithmetic processes, and performs overall control of the projector 1 by inputting and outputting signals to and from each unit via the bus 25. In the present embodiment, in particular, processing at the time of power-on and power-off of the projector 1 (hereinafter referred to as “start-up processing” and “stop processing”) is controlled.

  The ROM 22 stores a control program and control data used for the CPU 21 to perform various arithmetic processes. The control program includes an image processing program used in the video signal processing unit 12 described above. The ROM 22 also stores an OS (Operating System) that is basic software. The RAM 23 is used as a work area when the CPU 21 performs various arithmetic processes.

  The flash ROM 24 stores (learns) various remote control signals and has a first storage area 24a and a second storage area 24b. The first storage area 24a stores a remote control signal for irradiating each peripheral device when the projector 1 is powered on. On the other hand, the second storage area 24b stores a remote control signal for irradiating each peripheral device when the projector 1 is powered off. That is, the first storage area 24a and the second storage area 24b store remote control signals for controlling peripheral devices when the projector 1 is turned on and off. Registration of these remote control signals (learning of remote control signals) is performed by a learning operation using the above-described remote control learning button.

  With the above configuration, the projector 1 learns the remote control signal from the peripheral device remote controller 43 and irradiates the periphery of the projector 1 at a predetermined timing (when the projector 1 is turned on or off). can do. Hereinafter, a detailed description will be given with reference to FIG. 2 and FIG.

  First, a processing procedure for learning a remote control signal will be described with reference to the flowchart of FIG. First, when the remote control learning button is pressed by the user (S01), the projector 1 (CPU 21) displays a remote control learning menu (S02). In this remote control learning menu, when “learning for power-on” is selected by the user (S03), the projector 1 stands by in a state where the remote control signal from the peripheral device remote control 43 can be learned (S04).

  Subsequently, when a desired button of the peripheral device remote control 43 is pressed toward the remote control light receiver 13 by a user operation in the state of S04, the projector 1 is pressed by the user from the peripheral device remote control 43. The remote control signal corresponding to the pressed button is received (S05, remote control signal receiving means). Then, the projector 1 registers (records) the received remote control signal in the first storage area 24a (flash ROM 24) (S06).

  At this time, the projector 1 determines whether or not the received remote control signal has been successfully registered. When registration is not successful (S07; No), the projector 1 sounds an electronic sound indicating that learning of the remote control signal has failed and notifies the user of that (S08). Then, the learning process is finished. On the other hand, when the registration is successful (S07; Yes), the projector 1 emits an electronic sound (an electronic sound different from that at the time of failure) indicating to the user that the learning of the remote control signal has been successful. Notification is made (S09). Then, the learning process is finished.

  In addition, when “learning for power-off” is selected by the user in the remote control learning menu (S02) (S10), the projector 1 executes the processing from S11 to S16. In this series of processing, the received remote control signal is registered not in the first storage area 24a but in the “second storage area 24b (flash ROM 24)” (S13). Since the process other than the process of S13 is the same as the process of “power-on learning” (S03 to S09), a description thereof is omitted here.

  Note that the notification of the above S08 (S15) and S09 (S16) may be made to display a message indicating success / failure of learning of the remote control signal on the display unit 15 instead of the electronic sound, or the projection optics. The image may be projected on the screen SC by the unit 17. Or you may make it notify combining the ringing by an electronic sound, the message display on the display part 15, and the projection to the screen SC.

  Next, the startup process of the projector 1 will be described with reference to the flowchart of FIG. First, when the projector 1 (CPU 21) detects a power-on event (S21), it determines whether or not a remote control signal is registered in the first storage area 24a (S22). When the remote control signal is not registered (S23; No), the projector 1 shifts to a general power-on process (hereinafter referred to as “normal process”) of the projector.

  On the other hand, when the remote control signal is registered (S23; Yes), the projector 1 causes the remote control irradiation unit 16 to transmit one remote control signal (1) from the irradiation window formed on the four sides of the projector 1 main body to the periphery of itself. The first registered remote control signal) is irradiated (S24, remote control signal transmission means). Next, the projector 1 determines whether there is another remote control signal (S25). When another remote control signal exists (S26; Yes), the projector 1 emits the remote control signal (S24). Thereafter, the projector 1 repeatedly executes the processes after S24 until the irradiation of all the remote control signals registered in the first storage area 24a is completed. Then, when the projector 1 finishes irradiating all the registered remote control signals (S26; No), the projector 1 proceeds to normal processing.

  By executing the above startup process, for example, in the process of “learning for power-on” in FIG. 2, “remote control signal for stopping air conditioning equipment”, “remote control signal for turning off lighting equipment”, “ By learning in advance the "remote control signal to turn on the power", "remote control signal to close the electric curtain", and "remote control signal to lower the screen SC", the air conditioning is automatically stopped when the projector 1 is turned on. It is possible to create an environment suitable for projection, such as turning off the illumination, turning on the sound device, closing the electric curtain, and lowering the screen SC.

  Note that the projector 1 stop process differs from the projector 1 start-up process described above in that when the projector 1 detects a power-off event, the remote control signal registered in the second storage area 24b is emitted. Since the other processes are the same as the start process, the description here is omitted. By executing this stop processing, for example, in the “learning for power off” process in FIG. 2, “a remote control signal for starting an air conditioner”, “a remote control signal for turning on a lighting device”, “a power source for an acoustic device” By turning on the remote control signal for turning off the projector, the remote control signal for opening the electric curtain, and the remote control signal for winding the screen SC, the air conditioning is automatically activated when the projector 1 is turned off. Then, it is possible to return to the environment before using the projector 1 such as turning on the illumination, turning off the power of the audio equipment, opening the electric curtain, and winding the screen SC.

  As described above, according to the present embodiment, the projector 1 learns the remote control signal for controlling the peripheral device, and irradiates this signal to the periphery at a predetermined timing, so that the projector 1 is installed. The operation of a peripheral device can be controlled. As a result, the environment (installation environment) for using the projector 1 can be changed to a suitable environment without human intervention, and the burden on the user can be greatly reduced.

  In addition, remote control signals for controlling peripheral devices can be learned, and peripheral devices can be controlled using the learned signals, so there is no need for special functions on the peripheral device side, and existing devices can be used as they are. Can be realized at low cost.

  In particular, by controlling peripheral devices in accordance with operations that must be performed when using the projector 1 such as power-on or power-off, for example, there is no need to force the user to perform new operations for controlling the peripheral devices. The environment of the installation location can be set without imposing a burden on the user, which is convenient.

  The remote control signal that can be learned by the projector 1 is a peripheral device start / stop signal (in the case of an electric curtain, a signal for opening and closing the curtain, and in the case of a screen SC, the screen SC is raised (rolled) / lowered). Signal). For example, in the case of a lighting device, it may be a signal for adjusting the brightness (brightness adjustment signal) instead of turning on / off the illumination, and in the case of an air conditioner, a signal for setting silent operation. There may be.

  Moreover, it is possible to provide each component of the projector 1 shown in said embodiment as a program. Further, the program can be provided by being stored in various recording media (CD-ROM, flash memory, etc.). That is, a program for causing a computer to function as each component of the projector 1 and a recording medium on which the program is recorded are also included in the scope of the rights of the present invention.

  In the projector 1 shown in the above embodiment, one remote control irradiation unit 16 is employed, but a plurality of remote control irradiation units 16 may be included. In this case, it is determined whether or not a plurality of remote control signals are registered in the first storage area 24a (or the second storage area 24b). If a plurality of remote control signals are registered, a plurality of types of remote control signals are emitted. It may be.

  In the above embodiment, the transmissive liquid crystal display method is adopted as the display method of the projector 1, but a projector such as a reflective liquid crystal display method, a CRT display method, a light switch display method (micromirror device method), or the like. The display principle of 1 does not matter. In addition to the projector 1, the present invention can be applied to other display devices such as a television receiver. Other modifications can be made as appropriate without departing from the scope of the present invention.
