Title: Image processor
Inventor: HIGURE MASAKI
IPC: G06T3/00
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To exactly overlap images by correcting the images so as to match the object positions of the respective images based on the feature position information of input images and the deviation between the respective coordinates of position information at correspondent points. SOLUTION: A feature point setting part 33 sets the plural feature points (coordinates) of the input image. Image data around the feature points are segmented as a template and inputted to a correspondent point search part 35. The correspondent point search part 35 searches a point corresponding to the template in an image different from the image inputted to the feature point setting part 33 and outputs the correspondent point coordinate position to a correspondent point position memory 36. A correction parameter calculating part 37 reads out the feature point coordinate in a memory 34 and the correspondent point coordinate in a memory 36 and calculates the position relation (parallel moving amount or rotating angle) between two images. An interpolation operating part 38 corrects the images based on the inputted position relation and outputs them to an image synthesizing part 39.  The image synthesizing part 39 executes dynamic range expanding processing or object field depth expanding processing.

Abstract: PURPOSE:To prevent the erroneous demodulation and to extremely improve the reliability of a reproduction circuit by setting the optimum gain to the combination of drives and media to be used and also to the working environment. CONSTITUTION:The output signal B of a programmable gain amplifier 1 is supplied to a binarizing circuit 2 and then sliced by a comparator 2b at a prescribed slicing level. Thus, a gate signal D is produced and at the same time a differentiation signal C is produced with differentiation of a differentiation amplifier 2a. The signal C undergoes the zero cross slicing through a comparator 2c for production of a zero cross signal E. The signal E is supplied to an AND gate 2d which is controlled by the signal D for production of a peak position signal F. The signal F, i.e.,s a demodulated data pattern is supplied to a pattern deciding circuit 3. The circuit 3 decides whether the demodulated pattern is coinicident or not with a recording pattern in a prescribed deciding section. This deciding result is sent to a CPU 6a of a gain setting part 6.
