Patent ID: 7766486

Claim:
A projecting apparatus comprising: a projecting section having a zooming function to continuously vary a projection angle of view and configured to form a light image corresponding to an input image and project the image onto a screen as a projection target; an image capture section configured to capture a screen-direction image including the light image projected by the projecting section; an extracting section configured to extract a screen frame position from the image obtained by the image capture section; a distance measuring section configured to detect a distance to the screen and an angle with respect to the screen; an angle-of-view detecting section configured to detect the projection angle of view of the projecting section; a memory section configured to store corrected values, which are corrected for parallax of the projecting section and the image capture section, the corrected values being stored in a table to correspond to the distance to the screen and angle with respect to the screen and the projection angle of view of the projecting section; and a projection control section configured to refer to the memory section and obtain a parallax corrected value based on respective detection results of the distance measuring section and the angle-of-view detecting section, and to correct a projection range of an image projected from the projecting section based on the obtained corrected value in order to match the image projected from the projecting section to the screen frame position extracted by the extracting section; wherein, when the extracting section is unable to extract the screen frame position, an error message is projected for a given period.
