摘要:
A film correction system adjusts a relative position of film containing an area for information and a scanner of the film area. The system includes a scanner for scanning the film area at a film plane. A film drive moves the film along the film plane. A focused beam separate from the film area scanner scans a film edge in the film for determining a location of the film edge. A circuit is coupled to the focused beam scanner for changing a relative position of the film area scanner and the film area. The film edge scanner is a flying spot scanner, and the apparatus includes signal processors for processing the sprocket information. The system may be retrofit to an existing telecine apparatus. A separate coil may be used to provide deflection of a flying spot scanner used to scan the picture information on the film.

A processor includes an input for receiving video color component signals, and a circuit for deriving a luminance signal and a color magnitude signal from the video color component signals. A further circuit is provided for modifying at least one of the luminance and color magnitude signals whenever a composite video signal derived from the luminance signal in the color magnitude signal has a magnitude which exceeds a predetermined value. An output is provided for producing color component signals derived from the luminance and color magnitude signals from the modifying circuit.

An image processing system and method for converting two-dimensional images into three-dimensional images is embodied in a workstation with multiple interactive user interfaces configured to facilitate implementation of a variety of image processing techniques. By employing these tools and methodologies, an operator can rapidly render great numbers of objects in digitized images and observe the results in real time as algorithms pertaining to the object are adjusted.

摘要:
Video signal color correction is accomplished by selecting for color correction areas of the chrominance plane defining sectors in polar coordinants. Both the angle and the width of the sector can be changed to select precisely the desired signals for color correction. Specifically, component color difference video signals which only lie within a fixed hue sector are transmitted from an input to an output. Responsive to a first control signal, the difference signals are rotated through an angle which corresponds to a selected hue sector relative to the fixed hue sector in which the component color signals are to be corrected. The rotated difference signals are applied to the input to produce at the output an isolated color signal only when the difference signals lie within the selected hue sector. The width of the fixed hue sector is reduced responsive to a second control signal. Thus, the first and second control signals permit selection of the angle and the width of the sector in which the difference signals are to be corrected.

An image processing method and system for converting two-dimensional images into realistic reproductions, or recreations of three-dimensional images are embodied in a variety of interactive image processing tools that allow a user to apply any number or combination of image pixel repositioning depth contouring effects, algorithms or the like to create three-dimensional images with smooth realistic appearing surface contours.
摘要:
An exemplary method of reconstructing a hidden surface area in an image includes the steps of: identifying a separation pixel gap in an image resulting from a repositioning of image pixels to create a three-dimensional image; identifying pixels from one or more images; and filling the separation pixel gap with the pixels. Replacement pixels can be retrieved from a single image in a search sequence of images, or from a plurality of images in the sequence. One or more pixel fill techniques can be employed to determine replacement pixels for the separation pixel gap which best match adjacent background pixels.

A method for converting two-dimensional images into three-dimensional images includes: tracking an object in an image, the object having an object edge and an object outline thereabout, from frame to frame over a sequence of images; and creating object outlines in subsequent frames for converting two-dimensional images into three-dimensional images maintaining an object outline to object edge distance spacing relationship as the object moves or changes from frame to frame.
