Title: Ingemar Larsson: Innovator in Digital Imaging Technologies
Introduction
Ingemar Larsson is a notable inventor based in Malmö, Sweden. He has made significant contributions to the field of digital imaging, particularly in the areas of vignetting compensation and fixed pattern noise compensation. With a total of 2 patents, Larsson's work has advanced the quality and performance of digital cameras.
Latest Patents
Larsson's latest patents include a method for vignetting compensation in digital cameras. This innovative approach involves a two-step process. The first step is conducted during the production of the camera unit, where an image of a gray test screen is analyzed to generate a set of coefficients that describe a polynomial surface. The second step occurs for each image captured by the camera, applying a gain-table based on these coefficients to compensate for vignetting.
Another significant patent focuses on fixed pattern noise compensation with low memory requirements. This method addresses the fixed pattern noise seen in individual pixel offsets. By measuring the statistical distribution of noise for each camera during production, Larsson's system can compress and save this data. When an image is taken, the noise pattern can be retrieved and rescaled, ensuring high-quality images while minimizing memory usage.
