摘要： A projection video display apparatus includes a video input unit, a light source, a display element, a projection optical system, and a variable light adjusting function which changes the amount of light incident on the display element. Display modes using the variable light adjusting function are prepared, and one display mode of the display modes can be selected from a menu screen. Further, the display modes of the display video using the variable light adjusting function includes: a first display mode where the input video is displayed while changing a light adjusting amount in accordance with light adjusting control information, which is input from external equipment and is capable of controlling the variable light adjusting function in unit of frame of a projected video; and a second display mode where the input video is displayed while changing a light adjusting amount in accordance with the input video.

摘要： A display device according synthesizes icons and messages with a portion where no descriptive display image is displayed by OSD for display. Icon functions are set by a PC so that the setting of the operation of the PC and the display device, and the setting of an external device can be conducted. The number of lines of the message to be displayed is determined according to distortion correction at the case of oblique projection to correct position coordinates detected by a camera. In a presentation system including an interactive white board device, the display device (for example, a liquid crystal projector), and the PC, the display of the icons are improved to extend the functions, and the display of the messages at the case of oblique projection, and a position detection precision on a screen by the camera incorporated into the display device are improved.

摘要： In an image display system including a pen and a projection-type image display device having an interactive function, attributes such as a color and a thickness of a line or a figure to be drawn can be more flexibly switched at a lower cost. According to a typical embodiment, a pen-shaped pointing tool has a light emitting portion which emits non-visible light with a predetermined wavelength. The projection-type image display device has an interactive function unit which, from image data captured by a sensor performing image-capturing based on reflection light of the non-visible light with the predetermined wavelength reflected on the screen, recognizes a position of and a content of a light emitting pattern emitted from the pointing tool onto the screen, and executes process contents which are different from one another, based on the recognized position of and content of the light emitting pattern.
