摘要:
A 3D imaging device determines, during imaging, whether the captured images will be perceived three-dimensionally without causing fatigue while simulating actual human perception. In a 3D imaging device, a display information setting unit obtains a display parameter associated with an environment in which a 3D video is viewed, and a control unit determines during 3D imaging whether a scene to be imaged three-dimensionally will be perceived three-dimensionally based on the viewing environment.
摘要:
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.

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).

A 3D imaging device determines during imaging whether the captured images will be viewed three-dimensionally without causing fatigue while simulating actual human perception. In a 3D imaging device, a warning unit provides a warning to a photographer indicating that the captured images of the scene to be imaged will not be perceived as a 3D video having an appropriate 3D effect when a control unit determines that the captured images will not be perceived as such an appropriate 3D video. The 3D imaging device is prevented from obtaining an inappropriate 3D image (3D video).

摘要:
A 3D image signal processing device performs a signal processing on at least one image signal of a first viewpoint signal as an image signal generated at a first viewpoint and a second viewpoint signal as an image signal generated at a second viewpoint different from the first viewpoint. The device includes an image processor that executes a predetermined image processing on at least one image signal of the first viewpoint signal and the second viewpoint signal, and a controller that controls the image processor. The controller controls the image processor to perform an feathering process on at least one image signal of the first viewpoint signal and the second viewpoint signal, the feathering process being a process for smoothing pixel values of pixels positioned on a boundary between an object included in the image represented by the at least one image signal and an image adjacent to the object.

摘要:
Disclosed is a display device capable of compensating unevenness in brightness caused by physical restrictions of a display device or degradation in image quality caused by a partial reduction in contrast occurring in the local dimming technology using human visual characteristics. A liquid crystal panel (101) modulates illuminating light in accordance with the transmittance, and displays images on a screen. A backlight (102) emits the illuminating light to the liquid crystal panel (101) such that amounts of the illuminating light differ for each light emitting area of the screen. A backlight control unit (106) controls emission brightness of the backlight (102) for each light emitting area. A local gradation converting unit (104) performs gradation conversion on an image signal, and acquires a brightness value for each pixel after the conversion. A backlight driving unit (107) controls the transmittance for each pixel on the basis of the acquired brightness values after the conversion. The local gradation converting unit sets conversion characteristics for pixels to be processed in the image signal such that the brightness values of the pixels to be processed are low as the lightness of the periphery of the pixels to be processed is high, and performs gradation conversion using the set conversion characteristics.
