A method for generating a super-resolution image and related device is provided. In one aspect, the method comprises: receiving a first low-resolution image and a second low-resolution image, the first low-resolution image and second low-resolution image have a first spatial resolution and having been captured simultaneously by a pair of pixel arrays of a common image sensor, wherein the pixel arrays of the image sensor are located as to be diagonally shifted from each other by a sub-pixel increment; adaptively enhancing the first low-resolution and the second low-resolution images to generate an enhanced first low-resolution image and an enhanced second low-resolution image, respectively; mapping (e.g., non-uniformly) pixels of each of the enhanced first and second low-resolution images to a super-resolution grid having a spatial resolution greater than the first spatial resolution to generate a first intermediate super-resolution image and a second intermediate super-resolution image, respectively; and combining the first intermediate super-resolution image and second intermediate super-resolution image to generate a composite super-resolution image.

A method of synchronizing a line scan camera. The method comprises: obtaining line scan data of a region of interest (ROI) of a travelling surface from the line scan camera, the line scan camera being oriented perpendicular to a direction of travel of the travelling surface, the line scan data comprising a plurality of lines; identifying occurrences of a major frequency of a repeated texture on the travelling surface using characterized line scan data for each line in the plurality of lines of the line scan data; determining a period of the major frequency; and changing a line rate of the line scan camera when the determined period is different than a reference period.

A CMOS time delay and integration image sensor is disclosed having analog sampling stages coupled to the column bus that correspond to a pixel in the column. The analog sampling stages have a first memory element that stores the pixels reset level signal and a second memory element that stores an output signal of a previous analog sampling stage in the column. The analog sampling stage integrates the signal of the previous analog sampling stage with the sampled photosignal of the corresponding pixel and subtracts the reset level. The analog sampling stage architecture provides global shuttering and correlated double sampling and only requires a single analog to digital conversion for each TDI line time.

CMOS time delay and integration image sensor

A method of scanning pixels, each pixel including a photodiode and a sense node formed in the substrate, including a transfer gate coupled between the photodiode and the sense node, and including a memory gate coupled between the photodiode and the transfer gate. The method switches a control signal, connected to a memory gate electrode of all pixels, alternately between a first voltage and a second voltage that is intermediate between the first voltage and a substrate voltage. The first voltage transfers all photo charge in each photodiode into the respective memory gate. The second voltage both (1) holds all photo charge already transferred into the memory gate and (2) blocks further transfer of photo charges into each memory gate. The method further includes reading out photo charge from the memory gate on a row-by-row basis while the control signal is at the second voltage.
