摘要： High dynamic range image sensors and image reconstruction methods for capturing high dynamic range images. An image sensor that captures high dynamic range images may include an array of pixels having two sets of pixels, each of which is used to capture an image of a scene. The two sets of pixels may be interleaved together. As an example, the first and second sets of pixels may be formed in odd-row pairs and even-row pairs of the array, respectively. The first set of pixels may use a longer exposure time than the second set of pixels. The exposures of the two sets of pixels may at least partially overlap in time. Image processing circuitry in the image sensors or an associated electronic device may de-interlace the two images and may combine the de-interlaced images to form a high dynamic range image.

摘要： Electronic devices may include image sensors and processing circuitry. Image sensors may be used to capture multiple exposure images. Processing circuitry may be used to combine multiple exposure images into high-dynamic-range images. A motion correction method is provided that detects motion between multiple exposure images without using a frame buffer. A noise model is used to separate noise from motion for more accurate motion detection. A dilation operator may be used to enlarge a motion mask generated by the motion detector. Motion-corrected images may be generated from the multiple exposure images using a soft switch based on the motion strength. Motion-corrected multiple exposure images may be combined to generate a motion-corrected HDR image. A smoothing filter may be applied to the motion region of the motion-corrected HDR image. A blooming correction may be used to eliminate color artifacts in the motion-corrected HDR image.

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： 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.
