Image processing apparatus, image processing method, and computer-readable storage medium

摘要

An image processing apparatus includes an analyzing unit, a changing unit, and a control unit. The analyzing unit analyzes a projection image projected by a projection unit. The changing unit changes, depending on an analysis result obtained by the analyzing unit for the projection image, dimensions of the projection image projected by the projection unit so as to obtain a resized projection image. The control unit performs control for correcting a distortion of the projection image projected by the projection unit, in accordance with an analysis result obtained by the analyzing unit for the resized projection image.

主权项

1. An image processing apparatus comprising:
a detection unit configured to detect predetermined coordinates from a first captured image obtained by capturing a projection image projected by a projection unit; a determining unit configured to determine, using a result of the detection of the predetermined coordinates by the detection unit, whether dimensions of the projection image are to be changed; a changing unit configured to change, in a case where the determining unit determines that the dimensions of the projection image are to be changed, the dimensions of the projection image projected by the projection unit to obtain a second captured image based on a resized projection image; and a control unit configured to control a distortion correction parameter to be used for correcting a distortion of a projection image projected by the projection unit, in accordance with a detection result of the predetermined coordinates obtained by the detection unit for the second captured image based on the resized projection image in a case where the detection unit detects the predetermined coordinates from the second captured image.
