摘要： A projector that projects an image based on image data, includes alight source, a modulation unit that modulates light which is emitted from the light source, a light attenuation rate setting unit that sets a light attenuation rate based on the image data, and a light adjustment unit that adjusts intensity of incident light of the modulation unit, according to the light attenuation rate which is set by the light attenuation rate setting unit. The light attenuation rate setting unit sets a minimum value of an adjustment range of the light adjustment unit in a case where the image data is stereoscopic image data to a higher value than a minimum value of an adjustment range of the light adjustment unit in a case where the image data is not stereoscopic image data.

摘要： A projector modulates light emitted from a light source and projects the light, the projector including an image acquiring unit, a modulating unit, a light adjusting mechanism, and a light adjusting control unit. The image acquiring unit acquires an image from an image source. The modulating unit modulates the light emitted from the light sources, based on the image acquired by the image acquiring unit. The light adjustment mechanism reduces an amount of light incident on the modulating unit from the light source. The light adjustment control unit performs light adjustment control by the light adjustment mechanism, based on the image acquired by the image acquiring unit.

摘要： When a user instructs a control unit about a position in a substantially central portion of an illustration with an electronic pen, the control unit determines a rectangular area that surrounds the illustration as an enhancement area. An image adjustment unit carries out a process of shifting the portion in the enhancement area in an image for the left eye rightward by a predetermined amount and shifting the portion in the enhancement area in an image for the right eye leftward by a predetermined amount. As a result, the illustration located in the enhancement area is so changed that the image for the left eye is shifted to a position to the right of the image for the right eye and hence recognized as if the illustration were located in front of other illustrations. The illustration in the enhancement area is thus enhanced.

摘要： A method for controlling a display system is a method for controlling a display system including a first terminal, a second terminal, and a display apparatus that displays an image on a screen, and the method includes transmitting first transmission data representing a first image from the first terminal to the display apparatus and transmitting second transmission data representing a second image from the second terminal to the display apparatus. In a case where the display apparatus displays the first image on the screen based on the first transmission data but does not display the second image on the screen based on the second transmission data, the display apparatus controls at least one of the first and second terminals in such a way that the first transmission data has a larger communication traffic volume than the second transmission data.
