Abstract: The present invention provides a driving information providing apparatus, including: a light field camera which photographs an image in at least one direction of a vehicle to output image information; a driver sight line detecting unit which outputs a position of a view point in which a driver of the vehicle views the outside of the vehicle; a depth information calculating unit which outputs three-dimensional depth information from the image information; and an image outputting unit which outputs a predetermined image to the driver of the vehicle based on the position of the view point of the driver of the vehicle and the three-dimensional depth information, and a driving information providing method.

Abstract: An image sensor includes a pixel array, a micro lens array and polarizing filters. The pixel array includes a plurality of pixels. The micro lens array is disposed on the pixel array and includes a plurality of micro lenses. The micro lens overlaps a pixel group of the pixel array. The polarizing filter is disposed on the micro lens and includes a plurality of polarizing filters having at least two different polarizing phases. Accordingly, the accuracy and the reliability of the local auto white balancing may be improved.

Abstract: In one example embodiment, a lens calibration method includes generating a distorted image by distorting a pattern image that includes at least two reference points separated from a center of the pattern image by different distances. The method further includes generating lens calibration data by comparing the pattern image with the distorted image.
