Abstract: An apparatus for detecting an object of a vehicle is provided. The apparatus includes a camera that acquires an image from front of a vehicle and a controller that generates feature pyramid images based on a plurality of feature images extracted from the image. The controller also generates feature aggregation images by filtering the feature pyramid images, detects a pedestrian area from the feature aggregation images, and detects face regions from the feature pyramid images. At least one of the face regions that overlaps the pedestrian area is then determined as a face of a pedestrian.

Abstract: Provided is an image sensor. The image sensor includes a pixel array including a plurality of pixel blocks. Each of the plurality of pixel blocks includes a plurality of pixels arranged in a matrix form. Each of the plurality of pixels includes a plurality of phase difference sensing pixels. Each of the plurality of phase difference sensing pixels may be periodically repeatedly arranged in the pixel array in a horizontal direction and a vertical direction.

Abstract: The present invention relates to an auto-focus system and method based on a sensor, using hierarchical extraction and motion estimation for an image. The auto-focus method may include the steps of: (a) extracting a phase difference image from a sensed image; (b) extracting a robust feature image which satisfies a preset reference with respect to noise and out-of-focus blur, from the phase difference image; and (C) estimating a motion vector for lens shift from the feature image.
