Abstract: A display apparatus includes circuitry. The circuitry receives an input of hand drafted data with an input device. The circuitry converts the hand drafted data into first text data. The circuitry receives an input of first voice data. The circuitry converts the first voice data into second text data. The circuitry displays, on a display, third text data converted from second voice data in a case that the first text data and the second text data match each other at least in part.

Abstract: An image processing apparatus employable for an image projection system configurable with a plurality of image projection apparatuses includes a shift amount calculator to calculate a pixel shift amount for projection images projected by a first image projection apparatus and a second projection image projected by a second image projection apparatus on a projection face when a shift control of a light modulation device is performed for the first and second image projection apparatuses with a given cycle, a shift amount adjuster to calculate a deviation amount of the pixel shift amount of the first and second image projection apparatuses, and calculate a corrected shift amount to set the same pixel shift amount or to reduce the deviation amount of the pixel shift amount, and a shift amount output unit to transmit the corrected shift amount to at least one of first and second image projection apparatus.

Abstract: An image projection apparatus includes an on-screen display (OSD) processing unit to generate an OSD image, one or more image signal receivers to receive a first image signal and a second image signal from one or more external apparatuses, an image signal processing unit to generate a first image from the first image signal and a second image from the second image signal, to perform masking partially to the first image to set a display portion of the OSD image on the first image, and to perform scaling to the second image to match with the display portion of the OSD image to be virtually superimposed on the first image processed with the masking, and an image projection unit to sequentially display the first image processed with the masking and the second image processed with the scaling with a display ratio set for the first image and the second image.

Abstract: An image projecting system includes a master apparatus and an image projecting apparatus connected through a network. The master apparatus generates a correction parameter for correcting distortion caused in captured calibration image data of the image projecting apparatus, using the captured calibration image data and characteristic information of the image projecting apparatus. The image projecting apparatus corrects distortion using the correction parameter generated by the master apparatus to project a corrected projection image on the projection surface.
