Patent number: 8162487Abstract: A video projector includes a display device which receives an image signal and generates image light projected onto a projection surface. A scaling processor scales the input image signal. An OSD processor generates and corrects an adjustment pattern image in accordance with a correction instruction on the projection surface. An image signal synthesizer combines the image signal processed by the scaling processor with an OSD image signal generated and corrected by the OSD processor to generate a combined image signal. A trapezoidal distortion corrector performs trapezoidal distortion correction on the combined image signal from the image signal synthesizer based on the correction of the adjustment pattern image on the projection surface. The adjustment pattern image generated by the OSD processor includes a reference quadrangle pattern and downsized quadrangle patterns, which are reduced in size from the reference quadrangle pattern.Type: GrantFiled: April 30, 2009Date of Patent: April 24, 2012Assignee: Sanyo Electric Co., Ltd.Inventors: Kenji Ofune, Naoki Kaise
