Abstract: A light field synthesis method and a light field synthesis system are provided. The light field synthesis method includes inputting light field information corresponding to a scene into a trained learning model. The light field information is a light field having a plurality of views. The light field synthesis method further includes configuring the trained learning model to generate a synthesized light field according to the input light field information. The synthesized light field has a plurality of new views other than the plurality of views. The trained learning model is obtained by performing a training process on a learning model, and the training process includes optimizing the learning model in a refocused image domain, so as to minimize refocused image errors.

Abstract: A device is provided to generate a three-dimensional (3D) real image. A display panel is divided into several sub-areas for emitting scenes. Through a projecting lens-array unit, the scenes enter a fusion lens unit to form a real image of light field at a position beyond common barrier. Through an eyepiece unit, the image is emitted to human eye. Thus, the present invention provides a device for near-eye viewing, which reduces existing human-eye vergence accommodation conflict (VAC) in most augmented reality and mixed reality devices. Therein, the display of near-eye light field is a process of light-field reproduction, which merges the scenes and reduces aberration.

Abstract: A method and system of enhancing a backlight-scaled image include a minimum perceptible luminance threshold of cone response with dim backlight being determined, and a luminance layer associated with an image being extracted. The luminance layer is decomposed into an HVS response layer and a background luminance layer for each pixel of the luminance layer. Luminance of dark pixels of the background luminance layer is boosted and compressed to a perceptible range above the minimum perceptible luminance threshold, thereby resulting in an enhanced background luminance layer. An enhanced luminance layer is generated through composition using the HVS response layer and the enhanced background luminance layer as inputs.

Abstract: An image processing system and method include first processing a color stimulus relative to a first anchor, and then second processing a processed color stimulus relative to a second anchor. The first processing unit and the second processing unit preserve relative attributes of the color stimulus to enhance color sensation.

Abstract: A perceptual radiometric compensation system adaptable to a projector-camera system includes a brightness scaling unit that scales down brightness of an input image and obtains appearance attributes by a color appearance model (CAM). A hue adjustment unit adjusts hue of the input image toward tone of a colored projection surface by the CAM.
