摘要:
In an image forming apparatus, a color registration error correction computing portion calculates optimal typical value of position change quantity for each image forming region. Based on these typical values, write timing at each of write portions is controlled by an image control portion. That is, color registration error correction is executed based on optimal correction quantity for each image forming region.

The amount in offset of toner or the like is used to determine two points sandwiching lattice points of input data and divide the region between the two points equally in N−1. The output values at the two points and each point equally dividing the region are obtained to calculate gradients m1-m8 between any two adjacent ones of the points. Then, difference values dm1-dm7 in gradient between any two adjacent ones of the straight lines are calculated and (N−1) lattice points serving as dividing points are selected from the difference values in descending order. It should be noted that N is smaller than M. Then, the input and output values of the determined (N+1) lattice points N0-N4 are plotted and they are bounded by straight line and thus plotted to linearly interpolate the output data for the input data. Thus, an image processing apparatus can be provided capable of precisely modifying output images with reduced memory capacity.

According to the method of and apparatus for image processing, feature information of each picture element is extracted from image data received. An attribute of each picture element is determined on the basis of the aforesaid feature information. These attributes are corrected by detecting straight lines by applying a Hough transform to picture elements disposed along apparent border lines by which one attribute is divided from another, dividing the image data into a plurality of local regions by these straight lines, and determining an attribute with respect to each of the local regions. Each of the local regions is subjected to image processing in accordance with the corrected attribute.

摘要:
A digital planetarium apparatus includes an original image generator, an intermediate image generator, and a fish-eye lens. The original image generator is formed of two video projectors and generates semicircular images in display devices inside the respective video projectors. The intermediate image generator optically focuses the two semicircular images generated by the original image generator to thereby generate a circular image. The fish-eye lens projects the circular image generated by the intermediate image generator.
