Abstract: A spectro-colorimeter system for imaging pipeline is provided, the system including a camera system; a spectrometer system; and a controller coupling the camera system and the spectrometer system. In some embodiments the camera system is configured to provide a color image with the first portion of the incident light. Also, in some embodiments the spectrometer system is configured to provide a tristimulus signal from the second portion of the incident light. Furthermore, in some embodiments the controller is configured to correct the color image from the camera system using the tristimulus signal from the spectrometer. An imaging pipeline method for using a system as above is also provided. Further, a method for color selection in an imaging pipeline calibration is provided.

Abstract: A method is provided for calibrating a display having color channels. Each color channel is capable of adjusting settings for pixel values at gray level entries. The method includes selecting a gray level entry for calibration. The method also includes providing a target white point in chromaticity coordinates (x, y) and a target brightness at the selected gray level entry to the display. The method further includes adjusting the setting for the pixel values for the color channels at the selected gray level entry such that the display achieves the target white point and the target brightness at an adjusted pixel value.

Abstract: A head-mounted device is provided that includes displays configured to display an image and to simultaneously display a magnifying window that presents a magnified portion of the image. The magnifying window lies in a magnification plane that is fixed relative to a user's head. One or more processors in the head-mounted device can be used to perform a first ray cast operation to identify an input point where a detected user input intersects the magnifying window, to obtain a remapped point from the input point, to compute a directional vector based on the remapped point and a reference point associated with the user's head, to obtain a shifted point by shifting the remapped point from the magnification plane to another plane parallel to the magnification plane, and to perform a second ray cast operation using the shifted point and the directional vector.
