Patent Images

1. A method for transferring a first image and a second image, comprising:

  • generating a first image from a plurality of photodetectors of a pixel array, the first image including three image pixels in three different rows of image pixels in the first image, each of the three image pixels being generated from a different row among three adjacent rows of photodetectors in the pixel array;

    generating a second image from the plurality of photodetectors, each of the plurality of photodetectors contributes one light response output signal to the first image followed by another one light response output signal to the second image, said generating begins after a start and before a termination of said generating of the first image, the first and second images having different exposures;

    converting the first and second images to digital signals; and

    receiving the first and second images via at least one digital bus outside of and adjoining a processor into the processor in a time overlapping manner when the processor receives the first image for a very first time, said receiving of the second image begins before said receiving of the first image terminates and with a delay after said receiving of the first image begins, the delay having an increase for an increase in an exposure time of the second image, the processor comprising a memory to store at least a portion of the first image.
