摘要： An image sensor may include an image pixel array with both image pixels to gather image data and phase detection pixels to gather phase information. The phase detection pixels may be arranged in pairs, with two adjacent pixels covered by a single microlens. The phase detection pixel pairs may be arranged in dashed lines, with image pixels interposed between each phase detection pixel pair. There may be only one image pixel interposed between each phase detection pixel pair. The phase detection pixels may all include color filter elements of the same color. The phase detection pixels may all include green color filter elements. The image pixels in the interrupted lines may include color filter elements that match the surrounding color pattern. The image pixels in the interrupted lines may all include color filter elements of the same color.

摘要： An image sensor may include phase detection pixels that receive and convert incident light into pixel signals. Processing circuitry may use pixel signals from the phase detection pixels to determine an amount by which image sensor optics should be adjusted during automatic focusing operations. Phase detection pixels may include photodiodes with asymmetric angular responses. For example, the center of a photodiode in a phase detection pixel may be offset from the optical center of the microlens that covers that photodiode. A group of two, three, four, or more than four phase detection pixels may be clustered together and covered by a single microlens. Groups of these clusters may be arranged consecutively in a line. Phase data may be gathered using all of the phase detection pixels in the array, and image processing circuitry may determine which phase data to use after the data has been gathered.

摘要： An image sensor may have a pixel array that includes an array of pixels arranged in rows and columns. Each pixel may include a number of adjacent sub-pixels covered by a single microlens. The adjacent sub-pixels of each pixel may include color filter elements of the same color. Image signals from the sub-pixels may be used to calculate phase information in each pixel in the array. This information may be used to generate a depth map of the entire captured image. The pixels may each be able to detect vertical, horizontal, or diagonal edges. Additionally, the image signals from each photodiode in a pixel may be binned or average to obtain image data for each pixel. The image sensor also may generate high-dynamic-range images using the pixel array.

摘要： 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.

摘要： An imaging device may include an image pixel array with pixels used to gather phase detection information. The pixels in the image pixel array may use a photosensitive region to generate charge during an integration period. During the integration period, certain pixels in the image pixel array may not be needed to gather phase detection information. These pixels may be electrically connected to a bias voltage supply line during the integration period so that any generated charge is drained to the bias voltage supply line. Draining charge in the unused pixels may prevent blooming that would compromise the phase detection information gathered by neighboring pixels.
