Method for calibrating a vehicular vision system
A method for calibrating a vehicular vision system includes disposing a camera at a vehicle, disposing a processor at the vehicle, and disposing a video display screen in the vehicle so as to be viewable by the vehicle driver. The video display screen is operable to display video images derived from image data captured by the imager of the camera. Image data is captured by the imager of the camera and provided to the processor. The video display screen displays video images derived from image data captured by the imager of the camera. The processor generates a graphic overlay for display with the video images at the video display screen. Responsive to processing captured image data, the vehicular vision system is calibrated by adapting an orientation and position of the image data relative to the generated graphic overlay to a corrected orientation and position relative to the generated graphic overlay.

DEVICE CASE INCLUDING A PROJECTOR
One disclosed example provides a method for displaying a hologram via a head-mounted display (HMD) device. The method comprises, via a camera system on the HMD device, acquiring image data capturing a surrounding environment by detecting illumination light output by a projector located on a case for the HMD device. A distance is determined from the HMD device to an object in the surrounding environment based upon the image data. The method further comprises displaying via the HMD device a hologram, the hologram comprising a left-eye image and a right-eye image each having a perspective based upon the distance determined.

Compensating for Optical Change in Image Capture Device Components Over Time
Devices, methods, and non-transitory program storage devices (NPSDs) are disclosed to compensate for the predicted color changes experienced by camera modules after certain amounts of time of real world use. Such color changes may be caused by prolonged exposure of optical components of the camera module to one or more of: solar radiation, high temperature conditions, or high humidity conditions, each of which may, over time, induce deviation in the color response of optical components of the camera module. The techniques disclosed herein may first characterize such predicted optical change to components over time based on particular environmental conditions, and then implement one or more time-varying color models to compensate for predicted changes to the camera module's color calibration values due to the characterized optical change. In some embodiments, optical changes in other types of components, e.g., display devices, caused by prolonged environmental stresses may also be modeled and compensated.
