Abstract: A depth map generation unit 22 generates a depth map that generates the depth map from images obtained by picking up a subject at a plurality of viewpoint positions by an image pickup unit 21. On the basis of the depth map generated by the depth map generation unit 22, an alignment unit 23 aligns polarized images obtained by the image pickup unit 21 picking up the subject at the plurality of viewpoint positions through polarizing filters in different polarization directions at the different viewpoint positions. A polarization characteristic acquisition unit 24 acquires a polarization characteristic of the subject from a desired viewpoint position by using the polarized images aligned by the alignment unit 23 to obtain the high-precision polarization characteristic with little degradation in temporal resolution and spatial resolution. It becomes possible to acquire the polarization characteristic of the subject at the desired viewpoint position.

Abstract: A depth map generation unit (15) generates a depth map through a matching process using a first image generated by a first imaging unit which has a pixel configuration including pixels having different polarization directions and a second image generated by a second imaging unit which has a different pixel configuration from the pixel configuration of the first imaging unit. A normal-line map generation unit (17) generates a normal-line map based on a polarization state of a polarized image of at least one of the first and second images. A map unifying unit (19) performs a process of unifying the generated depth map and the generated normal-line map and acquires an image in which the number of pixels is not reduced while generating the depth map with precision equal to or greater than the generated depth map. The image in which the number of pixels is not reduced can be acquired while generating the highly precise depth map.

Abstract: There is provided an image processing device including a focus area setting section, a depth acquisition section, and a blur processing section. The focus area setting section sets each of a plurality of areas as a focus area, and the each of the plurality of areas is intended to be kept in focus in a captured image of a subject. The depth acquisition section acquires a depth of the subject in relation to each pixel in the image. The blur processing section sets each of the pixels in the image as a target pixel and performs a blur process on the target pixel in accordance with a minimum value of absolute value of each depth difference between depth corresponding to the target pixel and depth corresponding to each of the focus area.

Abstract: There is provided an image processing device including a depth acquisition unit and a smoothing processing unit. The depth acquisition unit acquires a depth to a subject in correlation with a pixel in a captured image of the subject, and the smoothing processing unit designates a pixel in a region excluding a predetermined region in the image as a target pixel, and performs a smoothing process of the degree according to the depth corresponding to the target pixel for a pixel value of the target pixel in a predetermined direction. This causes a pixel in a region excluding the predetermined region in the image to be blurred, thereby generating a panning image.
