发明名称 Display device and display control method
摘要 A projector displays an image supplied by a PC on a screen using a projection unit, detects a pointed location on the screen using a location detection unit, calculates first coordinates as coordinates of the pointed location in a displayable area of the screen using a coordinate calculation part, converts the calculated first coordinates into second coordinates as coordinates in the supply image using a coordinate conversion part based on image location information indicating a location of the supply image on the screen, outputs the second coordinates obtained by the conversion from an output unit, and corrects the image location information by processing of displaying the image based on a correction image using a control unit.

主权项 1. A display device comprising: a display unit configured to display a supply image supplied from an image source on a display surface; a location detection unit configured to detect a pointed location on the display surface; a coordinate calculation unit configured to calculate first coordinates as coordinates of the pointed location in a displayable area on the display surface, the displayable area being an area where the supply image can be displayed; a coordinate conversion unit configured to convert the first coordinates calculated by the coordinate calculation unit into second coordinates as coordinates in the supply image based on image location information indicating a location of the supply image on the display surface; an output unit configured to output the second coordinates obtained by the coordinate conversion unit to the image source; and a location correction unit configured to cause the output unit to output third coordinates specified in advance to the image source in response to a predetermined operation by a user and to correct the image location information based on a tip end location and a length of a reference pointer, the reference pointer being provided by the image source and displayed at the location corresponding to the third coordinates in the supply image by the image source.
