Image processing device and image processing method

Abstract

The present technology is related to an image processing device and image processing method that enables the generating of 3D images that can be viewed safely and comfortably. The communication unit acquires encoded data of 3D images, and the 3D image bitstream that includes at least the disparity information representing the disparity of these 3D images. The CPU specifies the playback timing of the 3D images. Based on the disparity information, the CPU determines the re-encoding section, which is the section of a front stream and back stream where adjustment of the disparity is needed, so that the difference between the disparity of 3D images of which the timings of playback are consecutive is at or below a predetermined threshold. The editing unit adjusts the disparity of the image data in the re-encoding section. The present technology is applicable, for example, to an editing device that edits 3D images.

1 . An image processing device, comprising:
 an encoding unit that encodes 3D images and generates an encoded stream;   a setting unit that sets estimated viewing environment information, which includes disparity information that includes binocular disparity amount for a main viewing region for the 3D images, a maximum screen width estimated as a viewing environment for the 3D images, and an estimated distance between the eyes; and   a transmission unit that transmits the encoded stream generated by the encoding unit, and the disparity information and estimated viewing environment information set by the setting unit.   
     
     
         2 . The image processing unit according to  claim 1 , wherein the setting unit further sets shooting condition information that includes an upper limit value for the binocular disparity amount;
 and wherein the transmission unit also transmits the shooting condition information set by the setting unit.   
     
     
         3 . The image processing device according to  claim 2 , wherein the disparity information includes position information representing the position in 3D images corresponding to the binocular disparity amount. 
     
     
         4 . The image processing device according to  claim 3 , wherein the disparity information includes the maximum binocular disparity amount that is the upper limit value for the binocular disparity amount, and the minimum binocular disparity amount that is the lower limit value for the binocular disparity amount. 
     
     
         5 . The image processing device according to  claim 4 , wherein the disparity information includes identifying information that identifies whether or not the binocular disparity amount is valid. 
     
     
         6 . An image processing method for an image processing device, comprising:
 a decoding step that decodes 3D images and generates an encoded stream;   a setting step that sets estimated viewing environment information, which includes disparity information that includes binocular disparity amount for a main viewing region for the 3D images, a maximum screen width estimated as a viewing environment for the 3D images, and an estimated distance between the eyes; and   a transmission step that transmits the encoded stream generated by the encoding unit, and the disparity information and estimated viewing environment information set by the setting unit.
