Problems solved by technology

[0010] In this case, in order to make a more effective presentation, it is better for the user to change the projection position of the image. However, every time the presenter changes, it takes effort and time to manually adjust the projection position of the projector, as well as to perform calibration.

Embodiment Construction

[0071] Hereinafter, the present invention will be described with reference to the drawings, taking as an example the case where it is applied to a projection type image display system using a liquid crystal projector. In addition, the embodiments shown below are not limited to the content of the invention described in the scope of the claims. In addition, all the configurations shown in the following embodiments are not necessarily essential as the invention solution means described in the scope of the claims.

[0072] (Overall description of the system)

[0073] Hereinafter, an example will be described where a liquid crystal projector is arranged in a living room of a family to project an image onto a wall.

[0074] FIG. 1 is a schematic explanatory diagram of an example of a projection area 40 according to the present embodiment.

[0075] When the wall is used as the projection target area 10 of the projected image, if there is an obstacle such as a painting 20 or a folia...

Abstract

To provide a projection type image display system, projector, program, information storage medium and image projection method which can project an image applicable to viewing environment of a changed projection position, a liquid crystal projector is provided with: a sensor 60 for sensing a projection target area and outputting sensing information; an edge detection section 146 for outputting detection information based on the sensing information; a projectable area determination section 144 for determining a projectable area based on the detection information; a projection area selecting section 142 for selecting a projection area from the projectable area; a sensing data generation section 170 for generating the sensing data applicable to viewing environment of the projection area, based on the sensing information of the selected projection area; an LUT data generation section 160 for generating LUT data, a correction section 120 for correcting image information based on the generated LUT data; and an image projection section 190 for projecting an image onto the projection area based on the corrected image information.

Description

technical field [0001] The invention relates to a projection type image display system capable of changing projection positions, a projector, an information storage medium and an image projection method. Background technique [0002] Projection-type image display systems such as liquid crystal projectors are being used in classrooms, movie theaters, conference rooms, exhibition halls, and family living rooms. [0003] When projecting images using a liquid crystal projector, etc., if there is an obstacle between the image projection unit and the projection surface, the projected light will hit the obstacle and an image will be generated, or the obstacle will block the line of sight and make it difficult to see the image. [0004] For example, a family living room is used not only by a user of a liquid crystal projector, but also by the user's family members. Therefore, even if the user secures a wide area on the wall as a projection area, the family members may arrange furni...
