Abstract: A focusing apparatus with a photoelectric converter which photoelectrically converts at least a pair of optical images formed by light fluxes that have passed a focus lens to output at least a pair of image signals, a phase difference detector which detects a phase difference between the pair of output image signals, and a driving amount calculator which calculates a driving amount of the focus lens based upon the detected phase difference. The driving amount calculator changes the calculated driving amount, in accordance with a first driving amount corresponding to a detected phase difference when the focus lens is located at a first position, a second driving amount corresponding to the detected phase difference when the focus lens is located at a second position, and a relationship between the first and second positions.

Abstract: A computational image processing filter processes an image from a wedge-based imaging system so as to remove artifacts such as blurring and ghost images. By removing the artifacts computationally instead of optically, manufacturing costs and complexity are reduced over prior solutions. In one implementation, the computational image processing filter performs a two-dimensional transform to align a ghost image with a pixel grid defined by the wedge. The transformed image is then stretched using a nonlinear transform to make the ghost pitch versus position a constant. Next, an anti-ghost point spread filter is created and deconvolved. Finally, an inverse of the nonlinear mapping is applied. Artifacts introduced by other optical layers can be reduced by deconvolving the artifact from the image according to a point-spread function representing an effect of the optical layers on the image.

Abstract: An image sensor may include a pixel array having image pixels for capturing image data and phase detection pixels for gathering phase information during automatic focusing operations. Phase detection pixels may form phase detection pixel pairs having first and second pixels with different angular responses. The first and second pixels may have color filters of the same color or may have color filters of different colors. The phase detection pixel pairs may be isolated from other phase detection pixel pairs in the array or may be arranged consecutively in a line. The phase detection pixels may, for example, be provided with color filters to match the color filter pattern of the pixel array. Processing circuitry may adjust red and green pixel signals from a phase detection pixel pair having a red and green color filter and may subsequently determine a phase difference using the adjusted pixel signals.
Abstract: An integrated-circuit image sensor generates, as constituent reference voltages of a first voltage ramp, a first sequence of linearly related reference voltages followed by a second sequence of exponentially related reference voltages. The integrated-circuit image sensor compares the constituent reference voltages of the first voltage ramp with a first signal level representative of photocharge integrated within a pixel of the image sensor to identify a first reference voltage of the constituent reference voltages that is exceeded by the first signal level.

Abstract: An approach is provided for tagging information based on contextual criteria. A tagging platform determines at least one criteria for associating information acquired by a device with at least one tag. The tagging platform also processes and/or facilitates a processing of context information of the device, a user of the device, or a combination thereof to determine a state of the at least one criteria. The tagging platform further causes, at least in part, an association of the at least one tag with the information based, at least in part, on the state of the at least one criteria. Such an approach allows for configuring the tagging of information prior to or upon initially acquiring the information.
