摘要： To achieve an image pickup element that can utilize polarized light as well as non-polarized light to image or capture an object, an image pickup element is provided to an imaging apparatus that forms an image of an object to be imaged onto a light-receiving surface of an image sensor, acquires a polarized filter image together with a regular luminance image, and executes image processing on the acquired images. The image pickup element includes, on a light-receiving surface LRS of the image sensor IMS, a polarizing filter PFL including at least two kinds of pixels having different transmission and polarization properties from each other.

摘要： An information processing apparatus (20) for processing stereo images of an object captured from a plurality of viewpoints to recognize the object includes a disparity calculator (32) to calculate a disparity of the stereo images by using a matching process. The disparity calculator (32) includes an evaluation value calculator (41) to calculate a correlation evaluation value in a search range set for the stereo images; an extreme value detector (43) to detect an extreme value of the correlation evaluation value calculated by the evaluation value calculator (41); a threshold setting unit (44) to set a threshold range for the detected extreme value; a counting unit (46, 55) to count the number of the extreme value existing within the threshold range; and an updating unit (44) to update the set threshold range to a new threshold range when a new extreme value indicating a higher correlation level of the disparity compared to the set threshold range is detected. The counting unit (46, 55) counts the number of the extreme value in a threshold range updated most recently in the search range.
