Abstract: A content processing apparatus 200 compresses image data of content in a lossy manner and transmits the image data to a head-mounted display 100 through an interface 300. An image processing integrated circuit 120 of the head-mounted display 100 transmits the image data to a display panel 122 through an interface 304 whose protocol is different from a protocol of the interface 300, without decoding and decompressing the image data. The display panel 122 displays the image that has been decoded and decompressed after being transmitted through the interface 304.

Abstract: A brightness parameter correction method and device and a brightness compensation system.

Abstract: An optical compensation device includes a luminance measurer that measures display luminance of a display device including a plurality of areas. A gamma corrector corrects a gamma voltage so that a first area of the plurality of areas has a gamma characteristic corresponding to a target gamma value based on the display luminance, and calculates a gamma value for each of the plurality of areas based on the display luminance. An optical compensator calculates a compensation parameter for each grayscale based on the display luminance and the gamma value. A luminance deviation for each of plurality of areas of the display device is compensated based on the compensation parameter.

Abstract: Shadow is an inseparable aspect of all natural scenes. When there are multiple light sources or multiple reflections several different shadows may overlap at the same location and create complicated patterns. Shadows are a potentially good source of information about a scene if the shadow regions can be properly identified and segmented. However, shadow region identification and segmentation is a difficult task and improperly identified shadows often interfere with machine vision tasks like object recognition and tracking. A shadow separation and contrast enhancement method based on the polarization of light is provided. Polarization information of scenes is captured by a polarization-sensitive camera and the scenes are processed to effectively separate shadows from different light sources.
