Abstract: The present disclosure provides a time delay integration (TDI) sensor using a rolling shutter. The TDI sensor includes two pixel arrays each having multiple pixel columns. Each pixel column includes multiple pixels arranged in an along-track direction, wherein two adjacent pixels or two adjacent pixel groups in every pixel column have a separation space therebetween. The separation space is equal to a pixel height multiplied by a time ratio of a line time difference of the rolling shutter and a frame period, or equal to a summation of at least one pixel height and a multiplication of the pixel height by a time ratio of the line time difference and the frame period. The TDI sensor doubles a number of times of integrating pixel data corresponding to the same position of a scene by arranging two separately operated pixel arrays.

Abstract: An image capturing module receives a predetermined number of a first set of frames by calibration of the image capturing device. An image processing module calculates focal values of each of the predetermined number of the first set of frames using a focal value calculation technique, identifies a predefined threshold of the focal value among each of the focal values calculated, determines a reference frame among each of the predetermined number of the first set of frames. An image comparison module compares focal value of one or more live frames with the focal value of reference frame, selects an optimal live frame from the one or more live frames when the focal value of the one or more live frames is greater than predefined percentage of the focal value of the reference frame. A notification module notifies an achievement of an optimal focal value range corresponding to the optimal live frame to an operator through one or more notification means.
