  • Method for electronic zoom with sub-pixel offset
    Patent number: 9741095
    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.
    Type: Grant

  • Method and apparatus for gain and level correction of multi-tap CCD cameras
    Patent number: 9113026
    Abstract: According to one aspect, embodiments herein provide a CCD sensor comprising a pixel array having a first segment configured to produce a first tap signal responsive to receipt of electromagnetic radiation from a scene to be imaged, a second segment configured to produce a second tap signal responsive to receipt of the electromagnetic radiation from the scene, a region of interest including a portion of the first segment adjacent the second segment and a portion of the second segment adjacent the first segment, and a processor configured to receive the first and second tap signals, perform level correction on one of the first and second tap signals based on magnitudes of the first and second tap signals, and perform gain correction on one of the first and second tap signals based on a comparison between magnitudes of the first and second tap signals corresponding to the region of interest.
