IMAGING APPARATUS AND METHOD OF IMPROVING SENSITIVITY OF THE SAME

摘要

An imaging apparatus and a method improving the sensitivity of the imaging apparatus are provided. The imaging apparatus includes a pixel binning unit pixel binning input image data to a given pixel size; a gain determining unit determining a pixel binning gain based on the input image data or the brightness of the input image data; and a calculating unit calculating output image data based on the pixel binned input image data and the pixel binning gain. Accordingly, the resolution of input image data can be preserved and the dynamic range of an image signal under low illumination conditions can be expanded.

1. An imaging apparatus comprising:
a pixel binning unit that pixel bins input image data to a given pixel size; a high pass filtering unit that filters high frequency components in a plurality of directions of the input image data; a resolution preserving factor determining unit that determines a resolution preserving factor based on the high frequency components; and a calculating unit that calculates output image data based on the pixel binned input image data, the high frequency components, and the resolution preserving factor.
