Abstract: A electronic display device designed to calibrate brightness levels in a flat-panel display by using adjacent code calibration for a variable electroluminescence voltage supply in the flat-panel display.

Abstract: An imaging system with a diffractive optic captures an interference pattern responsive to light from an imaged scene to represent the scene in a spatial-frequency domain. The sampled frequency-domain image data has properties that are determined by the point-spread function of the diffractive optic and characteristics of the scene. An integrated processor can analyze the characteristics of captured image data and select one of multiple available reconstruction kernels for transforming the frequency-domain image data into a spatial-domain image of the scene.

Abstract: An imaging system includes multiple diffractive optical gratings disposed over a two-dimensional array of photosensitive pixels. The different gratings present different patterns and features that are tailored to produce point-spread responses that emphasize different properties of an imaged scene. The different responses are captured by the pixels, and data captured from the responses can be used separately or together to analyze aspects of the scene. The imaging systems can include circuitry to analyze the image data, and to support modes that select between point-spread responses, selections of the pixels, and algorithms for analyzing image data.

Abstract: An image sensor with an array of pixels is provided. In order to achieve high image quality, it may be desirable to improve well capacity of individual pixels within the array by forming deep photodiodes in a thick substrate. When forming the array of pixels, conductive contacts may be formed in a back surface of the substrate opposing ground contacts located on a front side of the substrate. A conductive grid layer may be formed over the conductive contacts. A color filter layer may be formed over the conductive grid layer that may include a barrier grid in which color filter material is deposited. The conductive grid layer and conductive contacts may be biased to a voltage to improve the strength of electric fields in the substrate. Conductive contacts will thereby improve charge collection and electrical isolation and prevent electrical crosstalk and blooming.
