摘要： An electronic camera is adapted for processing images of different resolution to provide a user selectable image record size. A buffer memory is provided for storing color image pixels from a sensor as baseband signals corresponding to at least one image. A timing controller responsive to a resolution mode switch controls the order in which color image pixels are selected for storage in both vertical and horizontal directions. The order selected by the resolution switch includes a full resolution mode, and at least one reduced resolution mode in which the color image pixels are subsampled such that each chrominance image pixel is selected to be spatially adjacent to a selected luminance image pixel. Additionally, the buffer memory can store a burst of low resolution images.

摘要： In an electronic camera that can be utilized with a color filter wheel accessory for obtaining a color image composed of a sequence of red, green, and blue records, slight movement of the camera body can produce misregistration in the color records. Such misregistration can be determined by dividing the color image into a plurality of subsections, and selecting the particular subsection that meets a predetermined criterion for color neutrality, and that contains monochrome edge information suitable for correlation. The color records are brought into registration by processing the edge information of the selected subsection to determine the misregistration between the color records, and by shifting the misregistered records first by integer, and then by fractional pixel shift values.

摘要： A digital image processing system for displaying digitized images on a screen of a display unit includes a data base such as a compact disc on which the digitized images are stored, a plurality of image memories for holding the digitized images for display, and a display unit having a screen including a two-dimensional array of pixels. The screen is divided into sections by designating subsets of the screen pixels by row and column, and the images stored in the image memories are allocated to the sections of the screen by mapping image data pixels to the screen pixels. Under user control, different images may be displayed on different sections of the screen. The number of images, and the specific images from the data base, are user selectable and independently manipulable. To reduce a latency time for displaying images responsive to user commands, the images may be arranged in a sequence. Responsive to a user command to load a first image into an image memory and display it, one or more other images adjacent to the first image in the sequence are read from the data base and held in other image memories, otherwise unused. Thus, if a subsequent user command directs the system to display one of the adjacent images, the latency time for reading that image from the data base and holding it in another image memory is reduced.

摘要： A sensor 11 for a video camera includes a color filter array 12 of color filter elements covering a like array 14 of image sensing elements. Two fields of a video frame are provided by interlaced transfer of image signals from the sensor 11. The color filter array 12 is configured in relation to the sensor array 14 such that at least 75% of the image sensing elements are luminance-sensing (e.g., green) elements and the rest are chrominance-sensing (e.g., red and blue) elements. Furthermore, the chrominance-sensing elements of the same type (red or blue) are separated in a horizontal direction by at least three luminance-sensing (green) elements. The horizontal sampling frequency of the chrominance-sensing elements is increased by arranging horizontal lines containing the chrominance-sensing elements of the same type in staggered line pairs with the chrominance-sensing elements of one line appearing in different columns of the sensor in relation to chrominance sensing elements of the other line.

摘要： A zoom lens magnification control mechanism for a photoprint digitizing scanner contains an adjustable focus, zoom lens. The photoprint image projection path is incident upon a high resolution CCD sensor, image output signals from which are digitized for storage on a compact disc. Control of the operation of the scanner includes the use of a display device to which output signals provided by the photosensor are coupled so as to display the projected image. Whenever a photoprint is presented to the scanner an indication of the size of the photoprint is provided, as by way of a code stored on a photoprint platen, in order to set the magnification setting of the zoom lens. The photofinisher observes the display of the image projected on the photosensor and adjusts, as necessary, the operation of the zoom lens so that the image displayed by the display device fits the display screen. Using a program feature of a user interface, the photofinisher stores in memory information representative of the adjustment of the operation of zoom lens. Then, for subsequent presentations of photoprints to the scanner, the stored adjustment information is used as a magnification setting default value for a respective photoprint size. Whenever the magnification of the zoom lens is adjusted, there is an accompanying change in the focus ring of the lens, so that the displayed image is maintained in focus.

摘要： A method for decoding National Television System Committee (NTSC) signals which exploits redundancies in film-to-NTSC transcoding, known as "3-2 pull-down". The decoding method estimates luma (Y) and chroma (C). The "3-2 pull-down" structure assigns three NTSC fields to one frame of a film frame pair, and two NTSC fields to the other film frame. Luma and chroma in different film frames are separated using different methods, and the separated signals are better than the separated signals achieved using conventional one dimensional and two dimensional NTSC decoding methods. The new method for separating luma and chroma from composite NTSC signals can be combined with an interlace-to-progressive method, which converts the decoded 3-2 NTSC signals to 2 film frames, and an upconversion procedure, to yield improved image quality.

摘要： A digitized image previewer framestore apparatus enables a photofinisher to rapidly view what is seen by a high resolution CCD image sensor (but at a lower resolution) on a preview display. A selected portion or selected portions of the imagery data derived by way of the array of pixel elements of the high resolution sensor are controllably coupled to a pair of `ping-pong` write/read memories. The image resolution or storage capacity of each of memory is less than that of the high resolution CCD sensor and is considerably less than that of the 3072.times.2048 resolution of a high resolution color output image to be stored on compact disc. Depending upon the selected portion of the image incident on the CCD sensor is to be viewed, respective pixel and line rate clocks for the CCD sensor are subsampled and coupled to address generating counters used to access the ping-pong memories. As a result, only those CCD pixels for which (subsampled) clock signals have been generated will be displayed. By `ping-ponging` write-in and read-out of the memory pair, a first low resolution image may be written into one of the memories, while a second low resolution image is being rapidly read out and displayed. Then, at the end of the write-in frame interval, the contents of the newly loaded memory are rapidly read out to the preview display, while the next selected low resolution portion of the sensor image is being written into the memory the contents of which were previously read out and displayed.

摘要： A stereoscopic electronic viewer for a stereo image pair provided in a fixed medium includes a light source which passes light rays through the fixed images of the stereo image pair. The rays project onto a mirror which redirects the rays through a lens unit. The light rays from each image are associated with a particular lens in the lens unit which focuses the image onto an associated CCD image sensor. The two CCD image sensors have separate but synchronized electronics and provide a synchronized output which is fed to a stereo viewing device such as stereo goggles or a time-multiplexed polarized display. The electronic viewer is mechanically designed to manipulate the image produced on the display device to allow for panning and zooming of the stereoscopic image while maintaining the full resolution provided by the image sensor.

摘要： Electronic Imaging Apparatus is partitioned into separable modular units including an image pickup unit (4a) attachable to an image recording unit (2). The pickup unit (4a) is selected from a plurality of pickup units (4a, 4b), each producing image signals from an image sensor (6, 70, 71) uniquely devoted to the acquisition of a particular type of image (e.g., high resolution vs. low resolution, color vs. monochrome, NTSC motion vs. PAL motion). By providing an identifying signal in connection with the pickup unit, the characteristics of the sensor (6) are specified to the recording unit. More specifically, the recording unit includes a buffer (36) for storing the image signals, a processor (40) for controlling the operation of the recording unit, including the buffer, and interface circuitry (10, 32) for responding to the identifying signal and enabling operation of the processor (40) according to the characteristics of the attached image pickup unit (4a).

摘要： In a signal processing network including a color correction matrix and gamma compensation, detail processing is disclosed that includes a detail extraction circuit for generating a detail signal from an un-matrixed green signal and a detail enhancement circuit for adding the detail signal to the matrixed, gamma-corrected red, green and blue signals. The un-matrixed green signal is converted to a gamma-corrected green signal and separately input to vertical and horizontal high pass filters, which separate detail components representative of vertical and horizontal detail, respectively. The vertical detail is additionally input to a horizontal low pass filter to eliminate excessive enhancement of diagonal image components. The detail components are cored and input to the detail enhancement circuit. As a result of bypassing the color correction matrix and inserting the modified detail, including the diminished diagonal contribution, into the signal channel after gamma correction, the various detail components receive a substantially uniform visual enhancement regardless of orientation or density in the image.
