  • Patent number: 10924623
    Abstract: Systems and methods in accordance with the invention allow automatic recording, sharing, and communicating of different parameters associated with images and their imager to define a specific system behavior of a display device or an algorithm unit. Examples of information include imager parameters, environment parameters, image processing and enhancement parameters, coordinates of a section of wide-angle scene image content, display parameters, defined user experience, defined system behavior or any information to be recorded, shared, and communicated. To avoid loss of information, the information is encoded directly in the picture using a marker. This way, the information is robustly transferred from the imager to the display unit. According to the information, the final image can be automatically corrected and enhanced before display, different associated parameters can be displayed on final image or be used with another output.

  • Publication number: 20200394770
    Abstract: A method for enhancing a wide angle image to improve the perspectives and the visual appeal thereof wide-angle images uses custom adaptive dewarping. The method is based on the scene image content of recognized objects in the image, the position of these objects in the image, the depth of these objects in the scene with respect to other objects and the general context of the image.

  • Patent number: 10748243
    Abstract: An image distortion transformation method for transforming an original image by an imager having an original distortion profile to a transformed image optimized for a distortion processing unit includes inputting the original image from the imager into the transformation unit, inputting an original image distortion profile into the original distortion profile memory of the transformation unit, and inputting a target distortion profile into the target distortion profile memory of the transformation unit. The target distortion profile is different from the original distortion profile. The method further includes transforming the original image into a transformed image by transforming the distortion profile of the original image from the original image distortion profile to the target image distortion profile, and outputting the transformed image from the transformation unit.

  • Publication number: 20200252596
    Abstract: A stereoscopic vision system uses at least two cameras having different parameters to image a scene and create stereoscopic views. The different parameters of the two cameras can be intrinsic or extrinsic, including, for example, the distortion profile of the lens in the cameras, the field of view of the lens, the orientation of the cameras, the positions of the cameras, the color spectrum of the cameras, the frame rate of the cameras, the exposure time of the cameras, the gain of the cameras, the aperture size of the lenses, or the like. An image processing apparatus is then used to process the images from the at least two different cameras to provide optimal stereoscopic vision to a display.

  • Patent number: 10356400
    Abstract: An optimization apparatus for a camera system having lenses with at least one non-uniform parameter and a method to design them is disclosed. When the non-uniform parameter of the lenses is the presence of optical distortion, the image of the objects inside the optimization apparatus are deformed. Embodiments of the invention allow designing of optimization apparatuses using 2D or 3D objects pre-distorted according to the exact distortion profile of the lens. When viewed by a camera system with a lens having optical distortion, the image of the pre-distorted apparatus appears undistorted, and can be automatically analyzed with existing software programs or be compared to existing images by human observers.

  • Patent number: 8115950
    Abstract: An image reading system includes an information processing apparatus and a scanner connected to the information processing apparatus via a network. Upon receiving input of information that specifies the number of pages to be included in a file through an input unit and a web browser, the information processing apparatus transmits the information through a first communication unit to the scanner. The scanner reads image data through a reading unit, and divides the image data into files based on the information through a data management unit. The scanner transmits the files to the information processing apparatus through a second communication unit. The information processing apparatus displays images of the files on a monitor.
