A multichromic reflective coating is applied to a projector screen to reflect only those wavelengths produced by the projector, to accentuate selective wavelengths of light to be reflected. The screen can be a passive black substrate or an active grayscale screen such as e-ink paper, and un-reflected light reaches the screen which selectively tunes its grayscale to accentuate the brightness or darkness of the color video image being projected onto it and reflected by the multichromic reflective coating.

Systems enable viewing of video images over a plurality of scalable modular video displays include a video wallpaper subsystem and a video central computer subsystem. The video wallpaper has video displays having a same pixel pitch, and a width and height. The video displays include a video scaler and video mixer configured to enable video signals provided to the video displays to appear as one of a single video image a plurality of separate video images. Each of the video images appearing on a subset of the video displays as an overlay over the single video image, wherein the single video image and each of the plurality of separate video images are displayed at predetermined resolutions. The video central computer subsystem includes a video processing unit which receives video signals from a plurality of video sources and selects video signals to process and send to the video displays and includes a synchronizing frame buffer with time base correction to provide video synchronization of the selected video signals.

Various embodiments relate to an apparatus for controlling a lighting device. A light control circuit can use a controlled lighting sequence control and drive viewed sections of a lighting device to display chroma key color or emit infrared light, while driving other unviewed portions of the lighting device to display ambient and incident lighting. The viewed and unviewed lighting sections can be based on the field of vision of an image capture device and can change in relation to movements of the image capture device. A sensor can make measurements to determine to field of vision of the image capture device and can be used to generate or modify the controlled lighting sequence. An image processing circuit can generate a composite image using the chroma key while maintaining the subjects that are captured using ambient and incident lighting.

Methods and apparatuses are provided for synchronizing data by an electronic device. A first operation characteristic of a first image sensor of the electronic device and a second operation characteristic of a second image sensor of the electronic device are identified. At least one of a first access period of a first row of the first image sensor and a second access period of a second row of the second image sensor is changed, based on a difference between the first operation characteristic and the second operation characteristic, to synchronize the first access period and the second access period. The second row corresponds to the first row. Image data corresponding to the first row is acquired through the first image sensor based on the synchronized first access period. Image data corresponding to the second row is acquired through the second image sensor based on the synchronized second access period.
