摘要: A method, medium and apparatus for correcting a projected image is provided. The method includes detecting a pattern image based on photographing information of consecutive image frames into which a reference pattern and an offset pattern corresponding to the reference pattern are alternately inserted and which are projected onto a projection surface accordingly, and correcting projected image frame, based on the detected pattern image.

摘要: A method and apparatus are provided for unobtrusively estimating the characteristics of a projection surface, in order to correct the distortion of images resulting from the characteristics of the projection surface in the case of a projector. The method includes projecting at least one reference pixel and at least one counterbalance pixel corresponding to the reference pixel onto consecutive image frames, and correcting an image frame to be projected using correction information determined based on photographic information of the reference pixel.

摘要: An apparatus and method for inspecting a display. The apparatus includes a focus matching unit and an image control unit. A reference display receives a signal of a sample image during a first output period and displays a reference image according to the received signal. A target display receives the signal of the sample image during a second output period that does not overlap with the first output period and displays a test image according to the received signal. The focus matching unit may match display positions and sizes of the reference image and the test image. The image control unit may control the signal of the sample image stored in a predetermined memory to be output to the reference display during the first output period and controls the signal of the sample image to be output to the target display during the second output period.
