Title: Gerhard Renelt: Innovator in Image Transmission Technology
Introduction
Gerhard Renelt is a notable inventor based in Hamburg, Germany. He has made significant contributions to the field of image transmission technology. With a total of 3 patents, his work has advanced the methods used in transmitting facsimile pictures and changing image resolutions.
Latest Patents
One of Renelt's latest patents is a method of transmitting pictures, which involves transmitting black-and-white data represented by one binary position per picture element via run length coding. This innovative approach allows for the effective transmission of images where individual picture elements are represented by binary words with multiple binary positions. The method ensures compatibility with conventional facsimile receivers by processing only the most significant binary positions. Additionally, he has developed measures for preprocessing scanning values to achieve a smoothed sequence that can be transmitted more efficiently.
Another significant patent by Renelt is a method and circuit arrangement for changing the resolution of binary images. This invention converts a first pseudo-halftone picture into a second pseudo-halftone picture of reduced resolution. The process involves dividing the first picture into contiguous picture fields and selecting elements from each subfield based on a specific selection sequence. This innovative technique enhances the efficiency of image processing.
