Abstract: A method and a system are disclosed that use a double-readout technique to generate timestamps and grayscale values for pixel-specific outputs of a pixel row in a pixel array in which the pixel array forms an image plane and the row of pixels forms an epipolar line of a scanning line on the image plane. For a pixel-specific output that exceeds a threshold, a timestamp value and a grayscale value are generated and associated with the pixel-specific output. If a pixel-specific output does not exceed the threshold and no timestamp is generated (i.e., a missing timestamp), a grayscale value for the pixel-specific output is generated and associated with the pixel-specific output. Timestamps errors may be corrected that may be caused by missing timestamps, timestamps that are associated with pixel clusters and outlier timestamps, i.e., pixel-specific outputs that are not consistent with a monotonic relationship of timestamp values under normal conditions.

Abstract: Two-dimensional (2D) color information and 3D-depth information are concurrently obtained from a 2D pixel array. The 2D pixel array is arranged in a first group of a plurality of rows. A second group of rows of the array are operable to generate 2D-color information and pixels of a third group of the array are operable to generate 3D-depth information. The first group of rows comprises a first number of rows, the second group of rows comprises a second number of rows that is equal to or less than the first number of rows, and the third group of rows comprises a third number of rows that is equal to or less than the second number of rows. In an alternating manner, 2D-color information is received from a row selected from the second group of rows and 3D-depth information is received from a row selected from the third group of rows.
