Abstract:
A method for displaying a photograph on a digital picture frame comprising the steps of : retrieving a digital image file containing the picture from a digital storage media device; detecting an orientation of the photograph; and displaying the image on the digital picture frame in the correct orientation on a display unit of the digital picture frame.
Abstract:
An RGB-Z sensor is implementable on a single IC chip. A beam splitter such as a hot mirror receives and separates incoming first and second spectral band optical energy from a target object into preferably RGB image components and preferably NIR Z components. The RGB image and Z components are detected by respective RGB and NIR pixel detector array regions, which output respective image data and Z data. The pixel size and array resolutions of these regions need not be equal, and both array regions may be formed on a common IC chip. A display using the image data can be augmented with Z data to help recognize a target object. The resultant structure combines optical efficiency of beam splitting with the simplicity of a single IC chip implementation. A method of using the single chip red, green, blue, distance (RGB-Z) sensor is also disclosed.
Abstract:
Color filter arrays or mosaics are provided for imaging a scene with diffraction limited optics. A distribution of color types in a color filter array is biased toward smaller wavelengths to avoid or reduce loss of spatial resolution information at higher wavelengths due to a larger extent of diffraction at the higher wavelengths. Demosaicing methods for reconstructing a partial or full color image from raw image data involve applying correction factors to account for diffraction. The correction factors are based on pixel size and/or a measure of the extent of diffraction (e.g., an Air disk diameter for each wavelength in the color filter array.

An active pixel image sensor includes a photodiode structure which enables high near- infrared modulation transfer function and high quantum efficiency, with low pinning voltage for a medium- to large-size pixel. The photodiode includes a shallow photodiode region and a deep photodiode region both of a first dopant type, where the length of the shallow photodiode region is larger than the length of the deep photodiode region; and a shallow depleting region and a deep depleting region both of a second dopant type. The deep depleting region surrounds the deep photodiode region on at least two opposite sides.
