An image processing apparatus includes the following elements. An area designating unit designates an area to be processed from an input image. A delay amount setting unit sets an amount of delay in the area to be processed according to a distance from a reference position in the image. An angular velocity calculating unit calculates angular velocities at a predetermined position in images. An angular velocity storage unit stores records of the angular velocities calculated by the angular velocity calculating unit. A reading unit reads an angular velocity calculated at a time that is prior to a current time by the amount of delay set by the delay amount setting unit from the angular velocity storage unit when the image is changed within the area to be processed. A changing unit changes the image within the area to be processed using the angular velocity read by the reading unit.

Image processing apparatus and method, and program

An edge function is computed from two vertex coordinates given by a rendering target line. Gradient determination is then performed on the edge function, and the functions representing two shift lines that are formed by translating the rendering target line in the y-axis direction or x-axis direction depending on the angle formed by the rendering target line and the x-axis of the rendering plane coordinate system by 0.5d and &#x2212;0.5d will be computed, where d denotes the width of one pixel. Then, the number of subpixels included in a parallelogram, which has four points of the starting points and ending points of the two shift lines as vertices, is acquired so as to determine the pixel value of each pixel based on the number.

Drawing method, image generating device, and electronic information apparatus

An image processing apparatus for generating a three-dimensional model of a three-dimensional object from an image displaying the object in two dimensions includes a three-dimensional model generator operable to generate the three-dimensional model of the object from the image, and an extender operable to extend a lateral region of the three-dimensional model in a depth direction orthogonal to the two dimensions.

Method, apparatus, and computer program for processing image

A drawing processing apparatus is provided to solve the problems in which pixels of a drawing primitive with sub-pixel information may have an increased amount of data causing a burden on implementation. A setup processing unit sets up various parameters to allow a digital differential analyzer (DDA) to process the stream of a drawing primitive supplied from a primitive input unit. The DDA performs DDA processing on the drawing primitive supplied from the setup processing unit for conversion into pixel data. The DDA performs the DDA processing on a per rectangular pixel set basis along a scan line to output the pixel data of the drawing primitive on a per rectangular pixel set basis. A compression encoding unit encodes the sub-pixel information of each pixel contained in the rectangular pixel set by run length encoding for output to a FIFO buffer.

Drawing processing apparatus and method for compressing drawing data

An image processing apparatus capable of realizing accurate anti-aliasing with a small memory, without being affected by the order of drawing, and without inducing a drop in the drawing speed, including an anti-aliasing system obtaining edge information from an image after drawing, determining a processing content necessary for the anti-aliasing, and performing the determined processing. Specifically, either of the information of a z-buffer and the information of the normal vector at each pixel obtained at the time of drawing, or both information, is scanned or by the information of normal vectors restored from the information of the z-buffer is used, a state machine for holding the state and a counter for measuring the continuity of an edge are prescribed, the value of which pixel adjacent in which direction to each pixel on each edge and what kind of ratio to use for blending are determined, and the determined values are used for blending. This is performed successively until the pixel values are updated.

Image processing apparatus and method of same

An image converting apparatus for converting an image of an input video signal into an image with a metallic luster and representing the metallic luster with parameters designated corresponding to the input image. The apparatus is based on the concept that a model of reflected light can represented with a model of reflected light of diffusion reflection and mirror-surface reflection and that even though the resultant model of reflected light is three-dimensional data, assuming that the brightness of an input video signal linearly varies, the model can be represented with brightness data. A color correction circuit,has a look-up table with which calculations for generating an image with a metallic luster are performed with the brightness data and the designated parameters. A matrix calculating circuit extracts a luminous signal component from the input video signal. A pre-modifying circuit adjusts the amplitude. The color correction circuit performs calculations for generating an image with a metallic luster. Mix circuits mix output signals of the color correction circuit with an input video signal.
