Abstract: A system processes an image containing a first line and a second line, where the first and second lines includes a plurality of pixels, to generate an interpolated line. The system selects a first and second set of pixels from the lines and generates a first set and second set of filtered values. The system identifies in the first line an edge location in the first set of the filtered values by a first filtered value of the first set of filtered values being at least one of less than and equal to a first predetermined value and a second filtered value of the fist set of the filtered values being at least one of greater than and equal to the first predetermined value.

Abstract: A first device includes a processor, a first memory, and a memory manager. A second device includes a second memory and a first application program, and a third device includes a third memory and a second application program. The first application program is loaded into the first memory to be executed by the processor. Application program variables related to the first application are stored in the first memory. The second application program to be executed by the processor is loaded into the memory in at least a partially overlapping manner of the first application program. The creation of second application program variables related to the second application program in the first memory is in a region not occupied by the first application program. Alternatively, the first and second application programs may be in the same device and/or memory.

Abstract: A detector for a video signal includes a pixel comparator that compares a plurality of values of pixels of a first field of the video signal with corresponding pixels of a second field of the video signal. The second field is a second preceding field of the video signal in relation to the first field. The resultant values from the comparison is a set of pixel difference values. A counter determines a count value representative of the number of the set of pixel difference values that are either greater than a threshold value or less than the threshold value. A thresholder circuit determines a variable statistical value, such as an average, based upon a preceding series of the count values. The thresholder circuit compares the variable statistical value with the count value, or a percentage thereof, to determine whether the variable statistical value is greater than the count value or whether the statistical value is less than the count value.

Abstract: A system processes an interlaced video image that contains at least a first line and a second line, where each of the first and second lines includes a plurality of pixels. The system generates an interpolated line with a plurality of interpolated pixels located intermediate the first and second lines. The system selects a first set of the pixels from the first line and selects a second set of pixels from the second line. The first set of pixels are fitted to a first function and the second set of pixels are fitted to a second function. Preferably, the first and second functions are quadratic and independent of each other. The system calculates a shift factor based on either the zero of a first derivative of the first function and a zero of the first derivative of the second function or a horizontal shift of a first edge feature in the first function and a second edge feature in the second function. Depending upon the system these two shift factor calculation factors may describe the same technique.

Abstract: An encoder receives a video input that includes initial video data and encodes the initial video data as encoded video data, such that the encoded video data comprises fewer bytes than the initial video data. The encoded video data is transmitted through a computer network to a decoder that receives the encoded video data and reconstructs an image representative of the video input for viewing on a display. A sensor senses at least one of viewer information representative of at least one of a location and movement of a viewer, and display information identifying the display. Viewer data representative of the at least one of the viewer information and the display information is transmitted to the encoder to modify the method of encoding the initial video data.

Abstract: The system for viewing color video "automatically" enables and disables a color killer circuit (monochrome/color mode) so that the color video may be viewed in monochrome. Enabling and disabling the color killer circuit for the current system may be accomplished, in part, by dynamic operation of the television. In operation the user may select one of three methods of activating the monochrome/color mode to enable the color killer circuit. First, the monochrome/color mode may be activated for one or more preselected channels. Second, the monochrome/color mode may be activated for all channels. Third, the monochrome/color mode may be activated if a control signal is included within the television broadcast indicating that the particular video being received is a colorized monochrome video. To deactivate the monochrome/color mode may be accomplished by any of four deactivation methods that disable the color killer circuit. First, the monochrome/color mode may be deactivated by turning the television off and on.

Abstract: The apparatus is designed to adjust the zoom magnification control of a camera having a variable-magnification device, and includes a camera optical system for converting a scene into an image, a view finder for displaying said image to a user, a zoom control for changing the focal length of the lens, a detector coupled to the view finder for detecting a zoom condition of the user's face, and an analysis system for analyzing the detected zoom condition and for generating an input signal to the zoom control to change the focal length of the lens as a function of the zoom condition of the user's face.The method includes the steps of converting a scene into an image using a camera optical system; displaying the image to a user; detecting a zoom condition of the user's face with a zoom-condition detector; analyzing the detected zoom condition of the user's face; and generating an input signal to a zoom control for changing the focal length of the lens as a function of the zoom condition of the user's face.
