Abstract: A projector includes a recognition section adapted to recognize an image to be drawn and a drawing area in which the image is drawn based on a trajectory of a symbol written to a projection surface, an acquisition section adapted to acquire image data representing the image recognized by the recognition section, and a drawing control section adapted to perform control so that the image represented by the image data acquired by the acquisition section is drawn in the drawing area of the projection surface recognized by the recognition section.

Abstract: A projector includes: a detecting unit that detects, from input object data indicating contents of an input object input by handwriting, graph object data indicating an drawing area for a graph and data object data indicating data for forming a graph; and an image generating unit that generates, on the basis of the graph object data and the data object data, an image including the graph in the drawing area.

Abstract: An image data processing method for an image display system, includes: providing the image display system with an image display device, an information processing device, and a transfer section; obtaining a transfer ratio; setting a plurality of pixel data extraction blocks to the image data; comparing present frame data and previous frame data; setting a pixel position of pixel data to be transferred at present moment; transferring the pixel data to be transferred; setting a plurality of pixel data writing blocks in a display area of the image data; receiving the pixel data by the image display device; setting a writing pixel position and a writing pixel count used when writing the pixel data; and updating pixel data in the pixel data writing block by writing the pixel data into the pixel data writing block.

Abstract: In a key telephone system including SIP telephones forming a representative group, a main unit transmits, upon reception of an incoming call for the representative group, a “NOTIFY” message to all of SIP telephones forming the representative group to perform a calling operation. An answering SIP telephone answers the main unit by sending a “NOTIFY” message to the main unit. The main unit transmits a “200 OK” message to the answering telephone alone and transmits a “NOTIFY” message to an unanswering SIP telephone.

Abstract: A method for positioning a light modulation element of a projector. The projector including a first light modulation element unit having first through third light modulation elements and a second light modulation element unit having fourth through sixth light modulation elements. The projector further including a combining system for combining a first image light supplied from the first light modulation element unit and a second image light supplied from the second light modulation element unit and supplying the combined light, and positioning the first light modulation element unit and the second light modulation element unit such that color of combined light of color lights obtained from the first light modulation element, the second light modulation element, and the sixth light modulation element becomes a predetermined color.

Abstract: In a layout design, there are executed a step 201 of defining a permitted connecting relationship of an interface signal to be transmitted across different power supplies, a step 202 of extracting the interface signal between the different power supplies based on information about each of the power regions and information about a cell connection and optimizing a circuit in such a manner that the connecting relationship of the interface signal between the different power supplies is set to be one-to-one, a logic cell arranging step 203, a step 204 of verifying whether a logic cell of the interface signal between the different power supplies is arranged in a correct power region or not, an arrangement synthesizing step 205, a step 206 of confirming a timing and a slew before wiring, an arrangement correcting step 207, and a wiring step 208. Consequently, it is possible to carry out the verification between the different power supplies in consideration of physical information as well as logic information.
