摘要： A storage and interpolation device for digital television pictures having a memory organized in `tiles` of memory elements (2). Sub-assemblies of tiles (2A, 2B, 2C, 2D) all have the same coordinate address in one coordinate direction and have outputs coupled to an interpolation filter (6) operative in that direction. Individual tiles (2A; 2B; 2C; 2D) of respective sub-assemblies (1A, 1B, 1C, 1D) all have the same coordinate address in the other coordinate direction and the outputs of the filters (6) of the sub-assemblies are connected to inputs of a further filter (9) operative in the other coordinate direction. By allocating pixel values of discrete image areas of the picture to respective sub-assemblies (1A, 1B, 1C, 1D) in the horizontal direction and to groups of tiles (2A, 2B, 2C, 2D) in the vertical direction, interpolation can be effected by addressing all tiles simultaneously to produce a corresponding output from the filter 9.

摘要： In a digital video effects system a data store (13) is provided for storing the address within a frame store of image information from the corresponding image frame that is to appear within another image frame as transposed on to a curved surface. The addresses are stored in "curved" order so that when the store (13) is addressed via inputs (24) providing the coordinates of the scanning point of the television raster, the store (13) provides, at an output (25) that address within the frame store which contains the image information to be represented at the corresponding point in the final image. Such storage of the address values in "curved" order is achieved by applying at data inputs of the store a linear sequence of the coordinate addresses of the image frame store whilst providing at write addresses (11, 12) of the store data (13) corresponding values of the coordinates that have been transformed to define the curved surface to appear in the final image.

摘要： A control signal synchronized to a digital video signal to be processed and defining the position of a rectilinear line (51,52,53,54) relatively to the image frame (50) is generated by providing an initial value corresponding to the perpendicular distance of the origin (0) of the scanning point of the video raster from the line (51,52,53,54) and incrementing or decrementing this value during movement of the scanning point in accordance with the rates of change of this distance in the horizontal and vertical directions. By logically combining the signals corresponding to a plurality of lines (52,52,53,54) a further signal is obtained which is "true" when the scanning point is within a geometric figure defined by the lines. This signal can provide a "key" signal controlling the display within the figure of image information to be combined with the video signal. Signals relating to four lines (52,52,53,54) forming a quadrilateral can provide coordinate signals for interrogation of a frame store containing image information to be transposed into the area defined by the quadrilateral figure.

摘要： In a method of processing a video signal to provide digital video effects, an image signal is provided with an accompanying reference signal or Z-axis signal representative of the instantaneous distance of the scanning point of the video raster from an imaginary plane to be depicted as containing said information, taken in a direction perpendicular to the image screen. This reference signal may then be utilized to produce a variety of effects. For example a circuit for superimposing sets of image information to give the impression of an overlap in three dimensional space may comprise an order sorting circuit (1) having inputs (2,3,4) for sets of signals comprising picture information (P) a key signal (K) and a Z-axis signal (Z). At outputs (5,6,7) of the circuit the sets of signals are sorted into order of priority dependent on the magnitude of the Z-axis signal (Z). The picture signals (P) are mixed by multipliers (25,26,27) and a summer (28) to provide a composite picture signal in which the mixing of the components is determined by the multiplication factors of the multipliers (25,26,27). These factors are derived from the key signals having corresponding orders of priority, the key signals of lower order of priority being correspondingly attenuated by cascaded attenuators (12,13,14) coupled between lower order outputs of the sorting circuit (1) and a weighting circuit (11) for controlling the multipliers (25,26,27).

摘要： In a digital video effects system having a store (8) wherein coordinate values are stored in curved order by addressing the store with coordinate values transformed by a function generator (1) and transformer (2) and storing linear values derived from counters (6), the resolution of incremental values from the transformer (2) is increased as necessary to avoid unwritten addresses in the store by providing, between the transformer (2) and the store (8), delay means (3) for providing coordinates of the corners of adjacent quadrilateral areas defined by integer values of the transformed coordinates, a "predisector" (4) for providing coordinates of smaller quadrilateral areas into which the first areas can be divided, and a "hole filler" (5) for generating intermediate coordinate values failing within each smaller quadrilateral. An interpolator (7) serves to provide intermediate data values derived from the linear values to match the intermediate coordinate values generated by the hole filler.

摘要： A video image processing system for generating so-called "multi-freeze" digital video effects comprises a frame store (14) within which an image signal can be stored for application to a combining circuit (4) together with a background image signal (1) providing a background against which a trail of frozen images is to be displayed. The trail of images is derived by recycling images stored in the memory (14) through a further combining circuit (19) wherein the stored image is combined with incoming image signals applied to both combining means (4,19). Decay and patterning of the frozen images can be effected by circuits (24,25) for attenuating and profiling the key signals accompanying the image signals.

摘要： A solar energy collection system can include support devices made with bearings formed from sheet material. These bearings can be optionally formed so as to provide tool-less connections to their associated bearing housings. The bearings can be formed with an open configuration allowing a shaft to be inserted into an open bite of the bearing. Optionally, the bearing can be made from an ultrahigh molecular weight polyethylene plastic material. Additionally, two open-type bearing assemblies can be mounted axially offset and opposed to one another.

摘要： A control point based real time primary custom gamma curve generator for color correction equipment. A separate custom gamma curve generator circuit is provided for each of the RBG and luminance channels. A plurality of control points is provided and stored in a lookup table (LUT) stored in a random access memory (RAM). The control points are set and/or adjusted by the operator or loaded from a prestored set (e.g. a default custom gamma curve). The instantaneous input signal is divided into two portions—a control point address portion comprising the most significant bits (MSBs) of the input signal, and an interpolation address portion comprising the least significant bits (LSBs) of the input signal. The MSBs are used to select a particular control point value stored in RAM. The LSBs are used for interpolation of values with a smooth curve between control points. Also described are various user interfaces for the custom gamma curve generator.

摘要： A solar energy collection system can include a drive configured to adjust a tilt position of a solar collector assembly so as to tract the sun. The drive can include hardware for providing feedback control of the orientation of the solar collector assembly. A method for calibrating the drive can include moving the drive to a reference position and saving an output value from a sensor configured to detect the orientation of the drive. The reference value output from the sensor can then be used in determining the target output value from the sensor required to achieve a desired orientation.
