Title: Alan L Zimmerman: Innovator in Image Scaling Technology
Introduction
Alan L Zimmerman is a notable inventor based in Portland, OR (US). He has made significant contributions to the field of image processing, particularly through his innovative patent related to image scaling circuits.
Latest Patents
Zimmerman's most recent patent is titled "Image scaling circuit for fixed pixel resolution display." This invention focuses on an image scaling circuit designed to increase or decrease the size of a sampled image to match a fixed resolution display. The circuit incorporates mechanisms for resizing the image in both horizontal and vertical dimensions using independent sample rate converters. These converters adjust the image size by a factor of Lx/Mx in the horizontal dimension and Ly/My in the vertical dimension, where Lx and Ly are integers, while Mx and My are decimal numbers of arbitrary precision. This design allows for fine scaling control. Additionally, the circuit facilitates image warping by varying the down sample ratios Mx and My on a pixel-by-pixel and/or line-by-line basis.
