Abstract: The present invention enables image information of high resolution to be transferred via a transmission line with limited band width using a simple configuration. In transferring image information between a main body of a computer and a display, a dither matrix is used to update images stored in the display. That is, a plurality of blocks whose size is of a predetermined dither matrix are defined in an image, and information of each pixel in each block is transferred to the display in order of a value of a corresponding element in the dither matrix. Transfer of unchanged pixel data can be omitted. In addition, in transferring image information between the main body of the computer and the display, image information stored in the computer is divided into a plurality of blocks, for each of which the number of changed pixels or the number of writings to pixels in the block is calculated so that image information in blocks which exceed a predetermined number is transferred to the display block by block.

Abstract: Lighting parameters are received as floating-point numbers from a software application via an application programming interface (API). The floating-point numbers are converted to a fixed-point representation having a preselected number of bits. The number of bits is selected in accordance with a predetermined number of bits required by a frame buffer, which thus establishes the number of color values supported by the graphics display system. In order to preserve accuracy to within the number of bits in each value in the frame buffer, the representation in the fixed-point engine includes additional bits relative to the number of bits in the color values sent to the frame buffer. Floating-point values received via the graphics API are converted to fixed-point representations by first prescaling the floating-point values.

Abstract: A method and apparatus for dithering for color computer display systems includes the addition of a noise component to each of the color components of each pixel in a pseudo-random manner. The noise component is preferably different for each color component. Taking the image as a whole, the noise component repeats on a regular basis but is preferably selected so as not to repeat on adjacent pixels. The image is divided into squares of pixels and the same noise component is added to each of the same relative pixels from square to square. The preferred square of pixels is four pixels wide by four pixels high. The value of the noise component is chosen such that the most significant bit alternates both horizontally and vertically from pixel to pixel within the square of pixels.

Abstract: An adaptive auto-scrolling merge operation automatically accepts pen-based input data into a hand-held or palm sized computer and places the input data onto a line of a window in which a user intended the input data to be placed. Computing systems that accept input from users typically accept data items to be inserted into a scrollable window that is displayed by the computer. When a user is inserting data items at the end of the window, computing systems may automatically scroll the displayed portion of the window when data has been added to the last line of the window. Because pen based systems do not use a cursor located at an insertion point to know where a user wants new data items to be inserted, the new data items are inserted into the document at the location corresponding to the place within the window in which the user drew the pen strokes used to create the data item.

Abstract: A system displays an agent character, which does not give any anxious feeling to the user and is easy to use, by taking into consideration the position/posture of the user. Upon displaying the agent character, the distance from the user and the line-of-sight direction of the user are taken into consideration, and the agent character is inhibited from being located at the closest distance position in front of the user. When the user does not communicate with the agent character, the agent character is located in a far zone in front of the user. When the user communicates with the agent character, the agent character is located in a middle-distance zone in front of the user.

Abstract: A security method and system for protecting movie film images from being recorded by video cameras. The system is comprised of a means to generate an infrared pattern and a means to display this infrared pattern. The infrared pattern generated and displayed is of sufficient strength such that video cameras with infrared filters can not prevent the infrared pattern from interfering with the recording.

Video cameras aimed to record a screen containing the movie film images, even video cameras having infrared filters, are unable to prevent the infrared pattern from interfering with recording the movie film images, and one embodiment may completely obscure the picture being recorded and render it unacceptable for even pirated distribution.

Thus, the potential of an overflow barrier in the sensor sections is reduced.

Abstract: Systems and methods are provided for allowing a user to correct a discontinuous 2-3 field sequence within a disrupted video signal. A 2-3 field pattern fixer can be operated in a one-pass mode and/or a two-pass mode. In the one-pass mode, the disrupted video signal is analyzed to generate correction information, which is used to correct the disrupted video signal as it passes through the 2-3 pattern fixer, resulting in an undisrupted video signal with a continuous 2-3 field sequence. In the two-pass mode, the disrupted video signal is analyzed to generate correction information, which is then stored. This correction information is then used to correct a duplicate of the disrupted video signal, resulting in an undisrupted video signal with a continuous 2-3 field sequence. In this connection, the 2-3 field pattern fixer includes a field sequence detector, a field sequence analyzer, a field sequence generator and a multiple delay tap circuit.

Abstract: An ITU-R BT.656 (or similar) digital video signal is converted to analog at which point a simple 7-state state machine in combination with a 6 bit binary counter generates tri-level synchronized video. The state machine receives vertical and horizontal synchronization signals as well as End-Active-Video and Start-Active-Video signals from the ITU-R BT.656 video. A pixel clock clocks the 6 bit binary counter. Active video is passed directly to the output. Horizontal and vertical sync signals are mirrored at the output with the state machine generating a positive tri-level signal immediately following the horizontal synchronization signal. The high level signal is generated for a period of 44 pixel counts as counted by the 6 bit counter.

Abstract: To permit the use of a single remote control device in an AV system that can supply incompatible video signals, a switch box receives composite and S-video signals from an AV receiver, transforming these signals into the component video domain, and also receives component video signals from, e.g., a DVD player, with the output of the switch box being displayed on a television. The synchronization portion of the component video signal from the DVD player is sent to one of the input ports of the AV receiver as a trigger signal for comparison thereof with the synchronization signal in the switch box. When a user selects the AV receiver input port into which the trigger signal is input, the sense signal at the switch box is identical to the synchronization signal of the component video, and the switch box consequently sends the component video to the television. Otherwise, one of the video signals from the AV receiver is sent to the television.

Abstract: During image processing of video pictures, it is generally necessary to have fast, repeated access to adjacent picture blocks. Picture memories with a sufficient capacity to store complete video pictures do not have the necessary access time to perform image processing in real time. The invention therefore provides for the writing of picture blocks from a picture memory to a fast access memory. Only the pixels in the access memory are accessed when the image processing operation is performed. During the read-out, a further block from the picture memory is simultaneously read into the access memory. As a result, fast access to the picture data is possible in conjunction with little additional outlay in respect to memory. Areas of application for the method are in the image processing of video pictures.
