Abstract:

A light sensor system including a reference light source that moves in unison with a primary mirror and/or an inertial measurement device, and/or the reference light source is directed toward an obscured region of the light sensor system. The reference light source may allow for improved jitter compensation based on feedback of the reference light. The feedback may be representative of the elastic deformation of the optics and telescope optical axis. The improved jitter compensation may allow for the light sensor system (e.g., the housing and/or mirrors) to be built with less stiff materials, which can reduce the cost of manufacturing the present light sensor system compared to previously known optical sensor systems. In cases of high vibration levels which would otherwise degrade the resulting image quality after material stiffness property selections have been exhausted, the light sensor system may provide jitter compensation to improve video or still image quality.

Abstract:

A system and method for interpolating between pixels of an image for providing zoom and pan features. A piecewise cubic spline is used to find the values of each of four provisional interpolation points in each of four rows of an image and, similarly, a piecewise cubic spline is used to interpolate between the provisional interpolation points to find the value of a point in the output image. Boundary conditions used to constrain the coefficients of the piecewise cubic spline provide enhanced quality in the output image.
