An active-pulsed four-dimensional camera system that utilizes a precisely-controlled light source produces spatial information and human-viewed or computer-analyzed images. The acquisition of four-dimensional optical information is performed at a sufficient rate to provide accurate image and spatial information for in-motion applications where the camera is in motion and/or objects being imaged, detected and classified are in motion. Embodiments allow for the reduction or removal of image-blocking conditions like fog, snow, rain, sleet and dust from the processed images. Embodiments provide for operation in daytime or nighttime conditions and can be utilized for day or night full-motion video capture with features like shadow removal. Multi-angle image analysis is taught as a method for classifying and identifying objects and surface features based on their optical reflective characteristics.

The present technique relates to an image processing device and an image processing method for realizing high-precision image generation of predetermined viewpoints by using depth images on the receiving end when the depth images with reduced resolutions are transmitted. A parallax image resolution increasing unit increases the resolution of each of the parallax images of auxiliary images having half the resolution of a compatible image. A parallax image warping unit generates parallax images of virtual viewpoints by performing a warping operation on the parallax images of the auxiliary images with the increased resolutions based on the positions of the virtual viewpoints. A smoothing unit corrects the parallax values of the occlusion regions in the parallax images of the virtual viewpoints. The present technique can be applied to decoding devices that decode glasses-free 3D images, for example.

The present technique relates to an image processing device and an image processing method for realizing accurate depth image warping operations on the receiving end when depth images with reduced resolutions are transmitted. A partial resolution converting unit reduces resolutions of parallax images of auxiliary images. A partial conversion information generating unit generates partial conversion information. The parallax images having the resolutions reduced by the partial resolution converting unit and the partial conversion information generated by the partial conversion information generating unit are transmitted to a decoding device. The present technique can be applied to encoding devices that encode glasses-free 3D images, for example.

The present invention relates to an encoding device, an encoding method, a decoding device, and a decoding method capable of encoding and decoding multi-viewpoint images in accordance with a mode that is compatible with an existing mode. A compatible encoder generates a compatible stream by encoding an image A1 that is a compatible image in units of access units. An auxiliary encoder generates an encoded stream of a multiplexed image of auxiliary images by encoding a multiplexed image of images B1 and C1 that are auxiliary images used when multi-viewpoint images are generated from the compatible image in units of access units. A multiplexing unit transmits the compatible stream, a 3DV Representation Delimiter representing a boundary of a unit, and an encoded stream of the multiplexed image of the auxiliary images. The present technology can be applied to, for example, an encoding device that encodes a 3D image of the multi-viewpoint mode.
