Abstract: A three-dimensional image processing device for performing image correction processing on a three-dimensionally-viewed image includes a conversion unit and a composition unit. The conversion unit generates a converted image by performing tone conversion on a pixel value in an object included in the three-dimensionally-viewed image based on a relationship between a pixel value of a pixel of interest that is a processing target and a pixel value of a peripheral pixel of the pixel of interest. The composition unit synthesizes an n-th pixel in a first viewpoint image included in the three-dimensionally-viewed image and a corresponding pixel in a second viewpoint image included in the three-dimensionally-viewed image with a distribution ratio that is based on a subject distance of the n-th pixel. The corresponding pixel is located in the same spatial location as the n-th pixel.

Abstract: A visual processing apparatus comprises a spatial processing unit and a visual processing unit. The spatial processing unit is operable to perform a predetermined process to an inputted image signal using surrounding pixels of a target pixel and output an processed signal. The visual processing unit is operable to input the inputted image signal and the processed signal and output an output signal that is visual-processed. The visual processing unit has a property in which, in an area where a value of the image signal is almost equal to a value of the processed signal, a proportion of a change of the output signal to a change of the inputted image signal when the processed signal is fixed to a predetermined level is greater than the proportion when the image signal is equal to the processed signal.

Abstract: An imaging apparatus captures a large dynamic range image of a scene including a backlit person with a blue sky background in a manner that the person's face has an appropriate luminance level without saturating the background sky. An imaging unit obtains analogue image signals through exposure control that prevents a highlight from being saturated, an A/D converter converts the analogue image signals to digital image signals, and a signal processing unit linearly increases the dynamic range of the digital image signals. The image signals with the increased dynamic range are nonlinearly compressed to have a dynamic range of 100% or less through nonlinear dynamic range compression that intensively compresses a highlight portion. The imaging apparatus with this structure first increases the dynamic range of an image and efficiently compresses the increased large dynamic range of the image.

Abstract: A natural white balance is achieved in images that are captured while emitting a flash. The white balance of an image is adjusted using a WB adjustment portion and a mixture ratio calculation portion estimating a mixture ratio of an external light component and a flashed light component that are present in an image captured with emitting a flash, from the image obtained that is captured while emitting a flash and an image signal that is obtained without emitting a flash. Further, an external light WB coefficient determination portion determines an WB coefficient for the external light, a flashed light WB coefficient setting portion sets a WB coefficient for the flashed light, and a WB processing portion that continuously performs WB processing on the image captured while emitting a flash by using the mixture ratio as an interpolation ratio.

Abstract: In the three-dimensional imaging device (three-dimensional image processing device), the depth acquisition unit acquires L depth information and R depth information from a three-dimensional image. The image correction unit adjusts disparities of edge portion areas of a subject based on the L depth information and the R depth information such that the normal positions of the edge portion areas of the subject are farther away. Accordingly, when a three-dimensional image acquired by the three-dimensional imaging device is three-dimensionally displayed, the edge areas of the subject are displayed having a sense of roundness. As a result, a three-dimensional image that has been subjected to processing by this three-dimensional image processing device is a high-quality three-dimensional image that can appropriately reproduce the three-dimensional appearance and sense of thickness of the subject and has little of the cardboard effect.

Abstract: A 3D imaging device obtains a 3D image (3D video) that achieves an appropriate 3D effect and/or intended placement. The 3D imaging device (1000) estimates (calculates) an ideal disparity of a main subject based on a preset viewing environment (display condition) and a distance to the main subject, and obtains a disparity (an actual disparity) of the subject (main subject) actually occurring on a virtual screen. The 3D imaging device (1000) obtains a correction disparity using the ideal disparity and the actual disparity, and adds the calculated correction disparity to the 3D image (horizontally shifts the image) to perform appropriate disparity correction. The 3D imaging device (3000) obtains a 3D image (3D video) that achieves an appropriate 3D effect and/or intended placement without being affected by a disparity occurring in the horizontal direction caused by insufficient precision (in particular, insufficient optical precision).
