Definitions
- the present invention relates to an image display device and an image display method capable of projecting a stereoscopic image.
- the image display device can project a stereoscopic image by guiding one image (left eye image) to the left eye and the other image (right eye image) to the right eye. it can.
- the light emitted from the light source is divided into light having two orthogonal polarizations. Then, the left-eye image is formed by one polarized light, and the right-eye image is formed by the other polarized light.
- the image display device described in Patent Document 1 or 2 has a wavelength selection filter that selects and transmits light for each wavelength in order to form an image corresponding to full color.
- the light emitted from the light source passes through the wavelength division filter and is divided into light belonging to two different wavelength bands. Then, a left-eye image is formed by light belonging to one wavelength band, and a right-eye image is formed by light belonging to the other wavelength band.
- an image display apparatus using a wavelength division filter Since the method using the wavelength division filter does not need to pay attention to the change of the polarization plane of light, a stereoscopic image can be projected on a screen installed for projecting a two-dimensional image. Therefore, an image display apparatus using a wavelength division filter has an economical advantage.
- the image display device described in Patent Document 3 has a wavelength selective filter.
- the wavelength selective filter transmits illumination light from the light source by selecting the wavelength of the red band, the green band, and the blue band in the first band and the second band in a time division manner.
- the brightness of the image is greatly reduced as compared with the case of displaying a normal two-dimensional image. If a high-power light source is used, brightness is improved, but there is a problem that power consumption increases.
- An object of the present invention is to provide an image display device and an image display method that can solve any of the above-described problems.
- One embodiment of the present invention relates to an image display device that forms and displays an image with light emitted from a light source.
- the image display device is disposed on the optical path of light emitted from the light source, and the reflected light of the light is in a second wavelength band different from the first wavelength band and the light belonging to the first wavelength band. It has wavelength selection means for reflecting the light belonging to it with a predetermined period.
- the image display device is an image display device that forms and displays an image with light emitted from a light source, and can project a stereoscopic image such as a still image or a moving image.
- the wavelength selection means 2 is arranged on the optical path of the light emitted from the light source.
- the wavelength selecting unit 2 reflects, as reflected light, light belonging to the first wavelength band and light belonging to a second wavelength band different from the first wavelength band at a predetermined period.
- FIG. 2 is a schematic diagram showing a configuration of the wavelength selection unit 2 in the present embodiment.
- the wavelength selection means 2 has a circular plane.
- the semicircular region on the plane is the first reflecting surface 11 that selectively reflects light belonging to the first wavelength band, and the remaining semicircular region reflects light belonging to the second wavelength band.
- the wavelength selection means 2 having such a reflection characteristic can be manufactured by coating a dielectric multilayer film.
- the wavelength selecting means 2 of this configuration also serves as a reflection mirror for bending the optical path of the light emitted from the light source 1 by being installed in a place where the optical path of the light needs to be bent. As a result, an extra reflecting mirror can be removed from the image display device. As a result, for example, when compared with an image display device including a transmission-type wavelength selection filter described in Patent Document 3, one optical component through which light passes is reduced.
- the light use efficiency of the image display device can be improved by the amount of loss due to light transmission.
- the image display apparatus can display a bright image on the screen 10. Further, since the optical parts are reduced, the manufacturing cost of the image display apparatus is reduced.
- the wavelength selection means 2 preferably further has a function of transmitting infrared rays. Thereby, it can prevent that the component of an image display apparatus is heated by the infrared rays contained in the light which the light source 1 injects, and the temperature rise inside an apparatus is suppressed.
- the image display device provides a parallax between an image formed by light belonging to the first wavelength band (image for left eye) and an image formed by light belonging to the second wavelength band (image for right eye). Thus, the observer can perceive a stereoscopic image.
- the first wavelength band and the second wavelength band are defined as described below.
- 4A to 4C are conceptual diagrams for explaining the first wavelength band and the second wavelength band.
- FIG. 4B is a conceptual diagram showing a first wavelength band selected by the wavelength selection means
- FIG. 4C is a conceptual diagram showing a second wavelength band.
- the wavelength band of red light, the wavelength band of blue light, and the wavelength band of green light are each divided into two wavelength bands.
- red light means light of a single wavelength that is recognized as red light in optics.
- blue light and green light refer to single-wavelength light that is recognized as blue light and green light in optics.
- one of the wavelength bands divided into two in the light of each color belongs to the first wavelength band 14 respectively.
- the other of the wavelength bands divided into two in the light of each color belongs to the second wavelength band 15.
- the first and second wavelength bands 14 and 15 include the wavelength bands of the respective color lights recognized as red light, blue light, and green light, respectively. Therefore, an image corresponding to full color can be displayed on the screen 10.
- the light belonging to the first wavelength band and the light belonging to the second wavelength band in a predetermined cycle on the optical path from the light source 1 to the projection lens 9 in FIG. Can be generated.
- the rotation speed of the wavelength selecting means 2 is determined so as to correspond to the display cycle of the left-eye image and the right-eye image.
- the first and second wavelength bands 14 and 15 may be a set of a plurality of divided wavelength bands. Also, the first wavelength band 14 and the second wavelength band 15 are not limited to the above example, and any combination of wavelength bands may be used.
- the light integrator 3 is provided in order to make the light quantity distribution of light passing through the light integrator 3 uniform.
- the optical integrator 3 is installed as necessary.
- a rod-shaped rod integrator can be used as the optical integrator 3.
- the light integrator 3 may be disposed anywhere on the optical path of the light emitted from the light source 1 and between the light source 1 and the optical deflection means 7.
- the relay lens system 4 is provided to guide the light that has passed through the optical integrator 3 to the optical deflecting means 7 via the separating / combining means 8.
- the relay lens system 4 may be a single lens or a plurality of lenses.
- the relay lens system 4 is installed as necessary.
- the relay lens system includes a lens 5 for making the light that has passed through the optical integrator 3 parallel light, and a reflection mirror 6 for guiding the light to the separation / combination means 8.
- the separation / synthesizing means 8 is installed when configuring an image display device corresponding to color display.
- the separation / combination means 8 separates the optical path of the light incident on the optical deflection means 7 for each wavelength band. Thereby, since the optical paths of light belonging to different wavelength bands are separated, the optical deflecting means 7 can deflect the direction of light for each different wavelength band.
- the optical deflection means 7 has a plurality of deflection elements that can deflect the traveling direction of light.
- a plurality of deflecting elements independently deflect the light traveling direction, so that a desired image can be formed.
- the deflection element can be controlled to be on or off.
- the deflecting element in the on state deflects light in the direction in which the projection lens 9 for projecting light onto the screen 10 is arranged. Further, the deflection element in the off state deflects light in the direction in which the projection lens 9 is not disposed.
- the deflecting element is a reflecting surface that reflects light
- the deflecting optical means 7 can independently deflect the direction of the light incident on each reflecting surface.
- Each reflection surface is digitally controlled and can be switched between an on state and an off state. Switching between the on state and the off state can be realized by controlling the angle of the reflecting surface.
- the intensity of light that has passed through the deflection element can be adjusted by controlling the time during which each deflection element is on.
- a digital micromirror device DMD that can control light at high speed with low power is suitably used.
- a transmissive liquid crystal panel may be used as the image forming means instead of the optical deflection means 7 such as DMD.
- the light that has passed through the deflecting element in the on state is incident on the separating and synthesizing means 8 again.
- the separation / combination means 8 combines three types of light (red light, blue light, and green light) corresponding to the same pixel. Thereby, the image display apparatus can display a full-color image.
- the wavelength selection unit 2 may be installed at the position of the reflection mirror 6 included in the relay lens system 4.
- the wavelength selection unit 2 may be installed between the optical deflection unit 7 and the projection lens 9.
- the number of reflection mirrors can be reduced by installing the wavelength selection means 2 in a place where the optical path of the light emitted from the light source 1 needs to be bent. As a result, light loss is reduced and light utilization efficiency is improved.
- the image display device of the present invention is not limited to the above configuration.
- the present invention can be suitably used for any image display apparatus that has means for selectively using a specific wavelength.
- the image display method of the present invention is preferably implemented using the image display device of the above embodiment.
