摘要： A system and method for generating a variably scaled digital image. A second digital image containing a second plurality of pels is generated from first digital image containing a first plurality of pels. The first digital image may be stored in an image buffer. Each of the first plurality of pels is input serially into a process whereby a first and a second scaling factor are applied to the luminance values associated with a pel. A determination is made as to whether or not the scaled luminance values overflow vertically and horizontally into surrounding pels in the second plurality of pels. If the scaled luminance values overflow vertically, the overflow is stored in a line buffer to be added to future scaled luminance values. If the scaled luminance values overflow horizontally, the overflow is accumulated in an accumulator to be. added to future scaled luminance values. Once a pel in the second plurality of pels is completely filled with luminance values, the pel is output to a buffer and is ready to be displayed.

摘要： A method and device for rectifying an image photographed by a fish-eye lens, comprising the following steps: acquiring a fish-eye lens mapping parameter and a lens field angle (110); acquiring a fitted mapping curve according to the lens mapping parameter (120); acquiring centre coordinate and the radius of a fish-eye circle in a fish-eye image (130); creating a blank image used for rectifying the image according to the lens field angle (140); based on the lens field angle, the fitted mapping curve, the centre coordinate and the radius of the fish-eye circle, and the width and height of the blank image, mapping a point on the blank image used for rectifying the image to a corresponding point in the fish-eye image (150); and based on a colour sample of the corresponding point in the fish-eye image, drawing same onto the corresponding point in the blank image used for rectifying the image, and drawing the rectified image (160). According to the device and method, rectification is performed on an image photographed by a fish-eye lens so as to form an image with higher precision and further form a panorama image with higher precision.

摘要： A de-warping processing method for digital images includes the following steps. A first image window is segmented into a plurality of first blocks. A second image window is segmented into a plurality of second blocks according to locations and an amount of the first blocks. A coordinate transformation parameter is calculated by a group of first vertex coordinate values of the first block and a group of second vertex coordinate values of the corresponding second block. Each of coordinate values of the first block is transformed into an estimated coordinate value of the corresponding second block according to the coordinate transformation parameter. A pixel content value is obtained from the second image window according to each of the estimated coordinate values, and is written into a pixel with the corresponding coordinate value in the first block. All the first blocks are processed for outputting a first image.

The system may further comprise a transformation selector to generate control data to control a geometric transformation mapping based on the location of a current pixel being processed. In one embodiment, the system may also comprise a hardware geometric transform engine to perform a geometric transformation mapping by switching on one path through the geometric transform engine from an input window to an output pixel using the control data. In one embodiment, the system may further comprise an interpolator to generate interpolated geometric transformation mappings using the control data and multiple outputs from the geometric transform engine by switching on multiple paths from an input window.
