摘要： 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.

摘要： 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 −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.

摘要： An edge function is computed from two vertex coordinates given by a rendering target line 66 as shown in FIG. 8. Gradient determination is then performed on the edge function, and if the acute angle formed by the rendering target line 66 and the x-axis of the rendering plane coordinate system is 45 degrees or less, the functions representing two shift lines 68 that are formed by translating the rendering target line 66 in the y-axis direction by 0.5d and −0.5d will be computed, where d denotes the width of one pixel. If, on the other hand, the acute angle formed by the rendering target line 66 and the y-axis of the rendering plane coordinate system is more than 45 degrees, the functions representing two shift lines that are formed by translating the rendering target line 66 in the x-axis direction by 0.5d and −0.5d will be computed. Then, the number of subpixels included in a parallelogram abcd, which has four points of the starting points and ending points of the two shift lines 68 as vertices, is acquired so as to determine the pixel value of each pixel based on the number.

This is performed successively until the pixel values are updated.

摘要： An image processing apparatus capable of extracting edge information accurate enough to be able to be utilized for anti-aliasing without rendering of pixels other than the originally necessary drawn pixels and without inducing a drop in the drawing speed, including an anti-aliasing system for restoring edge information for an x-direction and a y-direction in screen coordinates from an image after drawing, determining a processing content necessary for the anti-aliasing from the obtained edge information, and performing the determined processing. Specifically, by scanning 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, or by using the information of normal vectors restored from the information of the z-buffer, the anti-aliasing is applied to each pixel.

摘要： 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 5 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.
