Patent ID: 8026952

Claim:
An image capturing device, comprising: a light sensing unit, sensing light to generate an analog image; a digital image generating unit, receiving the analog image to generate a digital image consisting of luma data and chrominance data; a first image preprocessing unit, integrating the chrominance data of adjacent rows to generate integrated chrominance data having reduced chrominance data volume; a plurality of line buffers, buffering the luma data and the integrated chrominance data for sub-image collection; and a second image preprocessing unit, receiving the integrated chrominance data from the line buffers and expanding the integrated chrominance data to generate pre-processed chrominance data, wherein each row of the integrated chrominance data are copied to the corresponding adjacent rows of the pre-processed chrominance data, wherein the luma data from the line buffers and the pre-processed chrominance data generated by the second image preprocessing unit are applied in displaying an image on a display.
