10484664 · 2019-11-19 · ·

A system captures a first hemispherical image and a second hemispherical image, each hemispherical image including an overlap portion, the overlap portion capturing a same field of view, the two hemispherical images collectively comprising a spherical FOV and separated along a longitudinal plane. The system maps a modified first hemispherical image to a first portion of the 2D projection of a cubic image, the modified first hemispherical image including a non-overlap portion of the first hemispherical image, and maps a modified second hemispherical image to a second portion of the 2D projection of the cubic image, the modified second hemispherical image also including a non-overlap portion. The system maps the overlap portions of the first hemispherical image and the second hemispherical image to the 2D projection of the cubic image, and encodes the 2D projection of the cubic image to generate an encoded image representative of the spherical FOV.

Method for tuning a three-dimensional image and a display apparatus thereof

The disclosure is related to a method for tuning a three-dimensional image, and a display apparatus thereof. In the method, an integral image composed of multiple element images and used to reproduce a three-dimensional image is obtained. The pixel values of every element image are extracted. Depending on hardware configuration, a certain range of the pixels within one-dimensional pixels of the element image are selected. The pixel values of the selected pixels are filled in the zones divided from the one-dimensional pixels in an ascending order or a descending order, and/or with continuously-duplicate values according to pixel numbers of the selected pixels. A new element image is therefore formed. By repeating these steps, a new integral image can be created. This new integral image effectively reduces the difference between the image regions and won't make a viewer see the uncomfortable three-dimensional image due to the excessively large difference.

DISPLAY DEVICE AND ELECTRONIC MIRROR

The present invention enhances instant readability by causing a driver to visually recognize, without a feeling of stranger an image obtained by photographing an area around a vehicle. A display section (11, 12, 13) is provided ahead of a driver, and the display section displays an image, obtained by photographing an area around an automobile (1), so that the image is recognized to be located on a deeper side away from the driver, an amount, by which a visible object is recognized to be located on a deeper side than a display screen, corresponding to a distance which causes the driver to recognize the visible object reflected by a mirror.

DIRECTED INTERPOLATION AND DATA POST-PROCESSING

An encoding device evaluates a plurality of processing and/or post-processing algorithms and/or methods to be applied to a video stream, and signals a selected method, algorithm, class or category of methods/algorithms either in an encoded bitstream or as side information related to the encoded bitstream. A decoding device or post-processor utilizes the signaled algorithm or selects an algorithm/method based on the signaled method or algorithm. The selection is based, for example, on availability of the algorithm/method at the decoder/post-processor and/or cost of implementation. The video stream may comprise, for example, downsampled multiplexed stereoscopic images and the selected algorithm may include any of upconversion and/or error correction techniques that contribute to a restoration of the downsampled images.
