    摘要: Electronic devices may include camera modules. A camera module may include an array camera having an array of lenses and an array of corresponding image sensors. Parallax correction and depth mapping methods may be provided for array cameras. A parallax correction method may include a global and a local parallax correction. A global parallax correction may be determined based on one-dimensional horizontal and vertical projections of edge images. Local parallax corrections may be determined using a block matching procedure. Further improvements to local parallax corrections may be generated using a relative block color saturation test, a smoothing of parallax correction vectors and, if desired, using a cross-check between parallax correction vectors determined for multiple image sensors. Three dimensional depth maps may be generated based on parallax correction vectors.

    摘要: Electronic devices may include camera modules. A camera module may be formed from an array of lenses and corresponding image sensors. The array of image sensors may include three color image sensors for color imaging and a fourth image sensor positioned to improve image depth mapping. Providing a camera module with a fourth image sensor may increase the baseline distance between the two most distant image sensors, allowing parallax and depth information to be determined for objects a greater distance from the camera than in a conventional electronic device. The fourth image sensor may be a second green image sensor positioned at a maximal distance from the green color image sensor used for color imaging. The fourth image sensor may also be a clear image sensor, allowing capture of improved image depth information and enhanced image resolution and low-light performance.

    摘要: An apparatus to facilitate image stabilization with user feedback is described. An embodiment of the apparatus includes an image sensor, a movement detector, and a digital processor. The image sensor acquires an image of a scene over an exposure period. The movement detector is coupled to the image sensor. The movement detector computes a movement measurement of the image sensor during the exposure period. The digital processor is coupled to the movement detector. The digital processor provides feedback to a user during the exposure period. The feedback is based on the movement measurement. Embodiments of the apparatus provide a simpler and less costly implementation for image stabilization.
