Patent ID: 8923552

Claim:
An apparatus for object detection, the apparatus comprising: an image acquisition unit configured to acquire image data; a reading unit configured to read image data, of a first frame in sequential frames, acquired by the image acquisition unit, in a predetermined image area with a predetermined resolution; an object area detection unit configured to detect an object area from first image data read by the reading unit; an object discrimination unit configured to discriminate a predetermined object from the object area detected by the object area detection unit; an area determination unit configured to determine an image area to read image data of a second frame succeeding to the first frame in the sequential frames based on the object area in the first frame; and a resolution determination unit configured to determine a resolution used to read the image data from the image area of the second frame determined by the area determination unit based on a first number of pixels in the object area of the first frame and a second number of pixels which can be read within a predetermined time period by the reading unit, wherein the reading unit reads the image data from the image area of the second frame determined by the area determination unit at the resolution determined by the determination unit.
