  • Patent number: 9525804
    Abstract: Image enhancement is achieved by separating image signals, e.g. YCbCr image signals, into a series of frequency bands and performing noise reduction on bands below a given frequency but not on bands above that frequency. The bands are summed to develop the image enhanced signals. The YCbCr, multi-band approach to denoising is able to operate independently—and in an optimized fashion—on both luma and chroma channels. Noise reduction is done based on models developed for both luma and chroma channels by measurements taken for multiple frequency bands, in multiple patches on the ColorChecker chart, and at multiple gain levels, in order to develop a simple yet robust set of models that may be tuned off-line a single time for each camera and then applied to images taken by such cameras in real-time without excessive processing requirements and with satisfactory results across illuminant types and lighting conditions.

  • Patent number: 9516215
    Abstract: A system that deters an unauthorized person from viewing the image in the display of a handheld electronic device. The handheld electronic device has a touch screen display. A touch security parameter requires a person to repeatedly tap the touch screen display with one or two fingers. The touch screen display will only accurately display an image for as long as the tapping continues. A camera security parameter senses the location of a face in the field of view of a camera. The touch screen display will only accurately show the image for as long as a face is detected in the camera's field of view. A position security parameter detects pitch and yaw with respect to the downward direction of gravity. The touch screen display will only accurately show the image for as long as the display is held within a range of acceptable positions.
