    Abstract: The present invention relates to an image processing method, image processing device and program which make it possible to shorten the processing time, and which also make it possible to set tile regions in appropriate ranges, by dividing one image into a plurality of regions and performing a transformation for each of these regions. The post-transformation image is divided into a plurality of tile regions, and transformation processing and the like are successively performed, with each of these tile regions as the object. In cases where a given tile region that is the object of processing contains a central axis that passes through the origin of the post-transformation image, the tile size of this region is altered by the tile size determining part 41 so that this region does not contain a central axis.

  • Patent number: 8265422
    Abstract: Method and apparatus for removing general geometric lens distortion from images. A geometric distortion removal algorithm is implemented according to a general 5-parameter distortion model that includes both radial and tangential lens distortion components. The algorithm may be implemented in a two-stage process in which one-dimensional elements in one planar dimension (rows or columns) of an input image with geometric distortion are rendered to generate an intermediate buffer, and then one-dimensional elements in the other planar dimension (columns or rows) of the intermediate buffer are rendered to generate an output image with geometric distortion reduced or removed. Thus, one-dimensional sampling is performed, and interpolation is performed in one planar dimension, rather than 2-D interpolation. An input row or column may be decimated, if necessary, before row or column interpolation is performed to generate an output row or column.

  • Patent number: 8229247
    Abstract: A method is operable to receive an image, where the image includes an input scene, which in turn includes one or more objects. The method associates a non-regular distribution of pins with the input scene, wherein each pin is associated with a respective portion of the input scene, wherein said associating transforms the image into a first deformation domain. The method can receive input specifying symmetry between the one or more objects in the input scene. The method may receive input to deform the input scene, and using that input, map the input scene from the first deformation domain into a second deformation domain, generating a corresponding output scene, while preserving the symmetry. The method detects structural and/or local similarities between the first and the second domain, and transforms the output scene from the second deformation domain into an output image while preserving both the structural and the local similarities.

    Abstract: The present invention relates to a technology of appropriately improving image resolution. According to an image signal processing method of the present invention, an input video signal contains an image signal whose pixel size is converted at a specified magnification scale. The input image signal is used to calculate sampling frequencies for image signals before and after the pixel size conversion. A ratio of sampling frequencies before and after the pixel size conversion is used to determine the specified magnification scale. A sampling phase for the image signal before the pixel size conversion is calculated from the input image signal after the pixel size conversion. A sampling carrier for the image signal before the pixel size conversion is generated from the sampling frequency and the sampling phase both before the pixel size conversion.

A transmitter (213) transmits the presentation characteristic to an external source of the second video content. A single device (401) may generate the video signal comprising both the first and second video content. In this case a characteristic of the overlaying is adjusted in response to the presentation characteristic.

  • Patent number: 7701518
    Abstract: Systems and methods which can shift video to the edge of the display screen. The user can electrically and mechanically roll up or down the projection screen to fit the opposite edge. Further, the electrically shifted position can be memorized in memory, which will be easily recalled during future use. Also, to avoid displaying visible noise near the top edge of the video, the video may be shifted to avoid such noise being visible. The shifted position may be stored in memory to be recalled for future use.

  • Patent number: 7679689
    Abstract: A video camera picks up an image of an operator. The picked-up image is subjected to a mirror image conversion. An image for operation, including operation buttons and the operator's image that is subjected to the mirror image conversion are mixed and displayed on a screen of a television receiver. The operator selects a desired operation button by using a universal remote controller with light emitting portions, and executes the operation on the screen. A detecting portion in the television receiver detects which operation button is operated, and executes a control operation corresponding to the operated operation button.

  • Patent number: 7609325
    Abstract: A method and an apparatus for calculating source image coordinates. In an embodiment, a variation rate of the source image coordinate with respect to a converted image coordinate is calculated by a recursive computation, and variation rates are accumulated to obtain the source image coordinate. Because the converted image coordinate sequentially increases one-by-one, the variation rate may be obtained by using adding operations of previously obtained source image coordinate, rather than multiplying operations with the all of the converted image coordinates. Therefore, the source image coordinates may simply and effectively be calculated.

  • Patent number: 7437018
    Abstract: An approach to resampling a first image that is sampled on a first sample grid. A filter for applying to the first image is computed. This involves computing a spatially quantized representation of the filter for which a degree of spatial quantization of the filter depends on factors including a measure of scale relating the first sample grid and a desired sample grid. The measure of scale can be computed based on a geometric transformation relating the first sample grid and the desired sample. The filter can be computed by selecting the number of spatial samples of the spatially quantized representation of the filter.

  • Patent number: 7379623
    Abstract: Systems and methods are disclosed that facilitate rapidly warping a two-dimensional image using integer math. A warping table can contain two-dimensional floating point output pixel offset values that are mapped to respective input pixel locations in a captured image. The warping table values can be pre-converted to integer offset values and integer grid values mapped to a sub-pixel grid. During warping, each output pixel can be looked up via its integer offset value, and a one-dimensional table lookup for each pixel can be performed to interpolate pixel data based at least in part on the integer grid value of the pixel. Due to the small size of the lookup tables, lookups can potentially be stored in and retrieved from a CPU cache, which stores most recent instructions to facilitate extremely rapid warping and fast table lookups.
