The PPFG symbology set includes broken line symbols representing an open tunnel and providing flow field data, a half-bracket symbol to indicate that the aircraft is no longer in the open tunnel represented by the broken line symbols, and a quickened flight path vector (QFPV) symbol to provide the pilot with predictive flight path information.

Abstract: An image processing device detects the correlation between a pixel to be removed in thinning pixel blocks generated by using a delay in horizontal and vertical directions and an adjacent pixel. The device then determines a coefficient corresponding to the correlation. From the pixel to be removed and the adjacent pixel, pixel data is generated by using a predetermined calculation equation. Thinning and reduction of each pixel block in the horizontal and vertical directions thus occurs.

Abstract: A method is provided for enhancing a digital image without distortion of the color. The result is an adjusted image which preserves the essential color of each and every dot in the input digital image while varying the effective light gathering power—like a virtual flash. The image enhancement is performed in RGB color space and comprises determining the maximum strength of the R,G, and B of a dot's RGB triplet and similarly for all dots. The dot maximums are scaled through a scaling function which is constrained in domain and range to the system's dynamic range. The same scaling factor that is applied to a dot maximum is also applied to each of R,G and B in the triplet. Preferably, a continuous scaling function is provided which smoothly approaches the minimum and maximum of the system's dynamic range for providing an aesthetically pleasing enhancement while maintaining true color.

Abstract: A flight guidance system providing perspective flight guidance symbology using positioning and terrain information provides increased pilot situational awareness of the pilot's aircraft. The guidance system uses a positioning system and a detailed mapping system to provide a perspective display for use in an aircraft. A precision pathway flight guidance (PFG) symbology set is thereby displayed on a pilot display. The PFG symbology set includes broken line symbols representing an open tunnel and providing flow field data, a half-bracket symbol to indicate that the aircraft is no longer in the open tunnel represented by the broken line symbols and a quickened flight path vector (QFPV) symbol to provide the pilot with predictive flight path information. A flight director system and tunnel generator component provide for updating the displayed PDFG symbology set based upon current aircraft conditions (e.g., aircraft position) and stored flight path information.

When image enlargement is selected by selectors (22-30), input video signals are processed by the contour correcting circuit (14), the frame memory (20), and the filters (16,18) in this order while, when image reduction is selected, input video signals are processed by the same in the reverse order.

Abstract: The basic configuration of Single local Adaptive Window Spatial Noise Reducer (SAW-SNR) is based on a preliminary de-noising low-pass filter followed by homogenous region segmentation to the considered pixel in a given local window. The configuration is composed also of an adaptive local mean estimator, an adaptive local statistic estimator which is preferably an economic standard deviation (SD) estimator and finally, a minimum-mean-square-error (MMSE) based de-noising technique. The proposed segmentation configuration outperforms existing spatial noise reducers in term of subjective and objective performances, in term of edge preservation, noise reduction in both homogenous regions or picture edges and Peak Signal to noise Ratio (PSNR). A second configuration in the form of a Parallel Multiple local Adaptive Window Spatial Noise Reducer (Parallel M-AW-SNR), is a combination of several basic configurations which implements different segmented windows.

Abstract: A communication device (100) employs a method and apparatus for indicating to a user of the communication device that only a portion of a received message (120) can be displayed to the user. Some time after receipt of a message, the communication device displays a portion of the received message and one of at least two different truncation symbols in the event that the entire message cannot be displayed. Each truncation symbol indicates to the user a particular reason why the entire received message could not be displayed. For example, if the entire message could not be decoded reliably, the communication device displays a portion of the message and a message error truncation symbol. Alternatively, if a length of the received message exceeds an amount of memory allocated for the message, the communication device displays a portion of the message and a message length truncation symbol.

Abstract: Telephone traffic is displayed on a screen so a message source and a message destination are represented by lines, such as vertical lines, for example, each with a label denoting its location. An arrow joining the location lines points in the same direction as the message and has an associated label indicating message identity. Further message source and destination locations are denoted by further lines, such as vertical lines, for example, only if the location is additional to a location already displayed. Otherwise an already displayed line denotes the relevant location. Further labelled arrows denote further messages. Each successive monitored message is denoted by a further arrow at a lower place on the display than the arrows denoting previous messages so successive items are added in a non-overlapping bottom-down manner.

Abstract: A method and an apparatus for outputting an on-screen display (OSD) of a display device are capable of preventing the display device from being damaged by the OSD, which represents an operation state of the display device. If an OSD activation signal which represents an abnormal state of the display device is inputted, a control section controls an OSD circuit section and outputs the OSD. If an output time of the OSD exceeds a predetermined reference time, a control section changes an output position of the OSD. The control section outputs the OSD to the changed output position. The control section repeatedly executes an operation for changing the output position of the OSD based on whether or not the output time of the OSD outputted to the changed output position exceeds the predetermined reference time.

Abstract: An image processing circuit having a delay unit U1 that delays image data Da and outputs image data as image data Db. The delay time of the delay units U1 is equivalent to the unit time of phase-rendered image signals VID1 through VID6. Upon a first difference circuit 31 subtracting image data Db from image data Da, and thus generating first difference image data Ds1, a first coefficient circuit 32 multiplies the first difference image data Ds1 by a first coefficient K1 and generates first correction data Dh1. Corrected image data Dout is generated by adding the image data Da and the first correction data Dh1. Therefore, ghosting is removed in the event of sequentially selecting blocks of batched multiple data lines to make display.
