摘要： An image capturing apparatus comprising: an image sensor; a setting unit configured to set, in the image sensor, a first region for obtaining a focus detection signal, and a second region, larger than the first region and contains the first region, for obtaining an image signal; a focus control unit configured to carry out focus control by finding an in-focus position of a focus lens using the focus detection signal output from the first region; and a readout unit configured to read out the focus detection signal from the first region and the image signal from the second region in parallel. The readout unit sets a framerate for reading out the focus detection signal to be higher than a framerate for reading out the image signal.

摘要： Progressive rounding error and convergence error encountered due to multiple use of a center correction adjustment of an image of a video projection display is reduced by calculating a 3×3 matrix for a moved color signal where the non center matrix values represent the difference between the initially measured sensor values stored at initial alignment, and stored most recently measured sensor values. The matrix center value is the sum of the averaged values calculated from the edge center errors, the stored sum of previous moves and the current move. Rerun of the sensor finding routine resets the stored move sum to zero.

摘要： An apparatus and a method for correcting a distorted image is capable of correcting an optical distortion of an image and misconvergence by prewarping an inputted image without using a convergence yoke, and an image displayer using the same. The apparatus for correcting an image distortion for an image displayer in which an image signal is inputted to display an image on a screen and an image distortion is corrected, includes: a reference image generator for generating a predetermined reference image; a camera for inputting the reference image and photographing an image outputted on the screen; and a distortion information extracting unit for comparing the photographed image outputted from the camera and the reference image outputted from the reference image generator, and generating distortion correction information to correct a distortion of the photographed image in case that the image has been distorted.

摘要： Systems and methods that facilitate automatic convergence and geometry alignment in projection systems such as a PTV. The automatic convergence system (ACS) preferably includes a CCD camera mounted inside the PTV and focused on the entire inside of a projection screen Fresnel lens. Alternatively, the ACS may include a deployable reflective sheet, preferably in the form of a roll up screen. In operation, signals from the CCD camera corresponding to test patterns projected onto the Fresnel lens or reflective sheet are analyzed and used to align, center or steer raster patterns to compensate for convergence error at a particular location. In a convergence mode, the video is blanked and then successive monochrome video test patterns are projected on the screen. The images captured by the CCD camera are used to memorize the location of landing points of one color test pattern from one of the projection units and then to align the other color patterns from the other projection units to the same landing points as the first color pattern. In a geometry alignment mode, the difference in brightness between an image striking the Fresnel screen and the over scanned area of the PTV cabinet is used to determine the border of the screen. This information is then used to provide reference marks for all geometrical adjustments done automatically using a similar process of successive test patterns and analysis.

摘要： Projection lens systems for use with cathode ray tube (CRT) projection televisions are provided which have positive first lens units (U1) and negative second lens units (U2) where the negative second lens units are customized in terms of at least one optical property for at least two of the colors of light produced by the CRTs with which the units are used. The at least one optical property is not spectral transmission, although the second lens units can also be customized for spectral transmission. As illustrated in FIGS. 1B–1F and FIGS. 8B–8F, such customization of a non-transmissive property provides an effective and cost effective approach for improving the color performance of CRT projection lens systems. Constructions for the positive first lens unit which improve image contrast and reduce manufacturing costs are also provided.

摘要： A convergence data recovering method and a projection television employing the same are provided. The convergence data recovering method includes storing a plurality of convergence data in a memory that are recognized as a data matrix, storing reference row data and reference column data for each row and each column of the data matrix in the memory, calculating comparative row data for each row based on convergence data forming each row of the data matrix, calculating comparative column data to each column based on convergence data forming each column of the data matrix, detecting target data according to whether the reference row data and the comparative row data are identical, and whether the reference column data and the comparative column data are identical, and recovering the target data. Accordingly, target data may be more accurately detected from the convergence data stored in the memory and then recovered.

摘要： Systems and methods are provided that facilitate automatic convergence and geometry alignment in projection systems. Preferably, an optical element such as a lens array is coupled to all areas of the projection system's screen and to a detector element such as a photocell array. In operation, each lens of the lens array is adapted to map an individual portion or region of the screen onto the photocell array. A microprocessor, controller or the like uses the data output from the photocells to instruct an alignment controller to center or steer the beams to compensate for convergence error at a particular location. In a center alignment mode, four (4) or more beacon dots located about the periphery of the screen are detected to determine screen size and position, which is used to center the video image and the centers of the mapped regions on the screen.

The intermediate parts 104a, 104b, 104c are constructed such that the convergence system has an improved resistance for variations in environmental effects like temperature and humidity. The intermediate parts 104a, 104b, 104c are constructed such that the convergence system has a high stability, a large degree of monolithicy and a high movement isotropy. When used in a projection display system, the projection display system has a high degree of color uniformity.
