Title: Carroll Francis Hamill: Innovator in Image Processing Technologies

Introduction

Carroll Francis Hamill is a notable inventor based in Boulder, CO (US). He has made significant contributions to the field of image processing, particularly in the area of scaling raster images. With a total of 3 patents to his name, Hamill's work has enhanced the quality of digital images, making them more suitable for various applications.

Latest Patents

Hamill's latest patents focus on non-integer scaling of raster images. One of his methods involves scaling a binary image by a non-integer factor while enhancing its quality. This method includes selecting a pel in an input bitmap, choosing a neighborhood around that pel, and comparing it with preselected image feature patterns. When a match is found, a block of bits is written to the output bitmap, which is derived from an image-enhancing tile corresponding to the matched pattern. This process is repeated for each pel, resulting in an output image that represents a non-integer scaled version of the input bitmap with improved quality.

Another patent by Hamill also addresses non-integer scaling of raster images with enhanced image quality. This method involves selecting a pel in the input bitmap and searching for a matching image feature pattern. The appropriate block of bits is then written to an intermediate bitmap, smoothing out jagged features and improving overall image quality. This technique is particularly beneficial for scaling raster font characters to match the resolution required by output devices.
