Title: Innovations by Detlef Schweng
Introduction
Detlef Schweng is a notable inventor based in Weinstadt-Schnait, Germany. He has made significant contributions to the field of digital imaging, holding a total of 11 patents. His work focuses on enhancing color representation and image processing techniques.
Latest Patents
One of Schweng's latest patents is a sensor arrangement for transforming color space representation in a digital color image. This invention provides an extended luminance range and an improved color implementation. It enables an easy transformation into another color space with luminance as a component. The key aspect of this invention is the addition of white pixels to the red, green, and blue pixels. These white pixels either have an extended dynamic range or are larger than the RGB pixels used. The output of these white pixels can be directly utilized for the luminance values of the destination color space, simplifying the calculation of color values from RGB values. An example of this transformation is the conversion to the YCbCr color space.
Another significant patent by Schweng is a zoom algorithm that allows for zooming into a region of interest within a digital image. This method supports both the decrease and increase of resolution based on the scale of zooming. The region of interest is variable, while the destination image maintains a fixed size. When decreasing resolution, the method combines interpolating source pixels to calculate destination pixel color values while omitting some rows of source pixels. Conversely, when enlarging, it combines interpolation, extrapolation, and replication of interpolated rows to achieve the desired resolution.
