With a total of 5 patents to his name, Rosengaus has developed innovative systems and methods that enhance the capabilities of image sensors in various applications.

Latest Patents

One of Rosengaus's latest patents focuses on "Event detection using motion extracted image comparison." This patent describes systems, methods, and apparatus for generating motion extracted images with a high dynamic range (HDR) based on image data obtained from one or more image sensors at different times. The implementations may utilize a single image sensor or camera that captures images at varying exposures sequentially. The processed images can detect moving objects within the field of view, allowing for the extraction of pixel information corresponding to those objects. The non-extracted image data is then combined to produce a motion extracted HDR image that is largely devoid of the moving object.

Another significant patent by Rosengaus involves "Aligning and blending image data from multiple image sensors." This invention outlines systems and methods for generating HDR images based on data from different image sensors, which can be used for event detection and inventory monitoring within materials handling facilities. The image sensors are aligned and calibrated, capturing data at approximately the same time but with different exposures. The image data undergoes preprocessing, matching, alignment, and blending to create an HDR image that avoids overexposed and underexposed regions.
