One embodiment provides a method, including: receiving, at an information handling device, user input to generate a three dimensional projection of an object in physical space; generating, using a projection source, a plurality of perspective views of the object, wherein each of the plurality of perspective views is associated with a different angle of the object; and providing, using the plurality of perspective views, the three dimensional projection of the object at a predetermined location in the physical space using at least one reflective surface. Other aspects are described and claimed.

A control device includes a processor, the processor is configured to: generate third image data based on first image data and second image data; and output the third image data, and a second image based on the second image data in a third image represented by the third image data is an image indicating that specific content is associated with the third image, and surrounds a first image based on the first image data in the third image.

An image adjustment device includes: an illumination component derivation unit that derives an illumination component of a grayscale image; a reflectance component derivation unit that derives a reflectance component image that is a resulting image in which the illumination component is removed from the grayscale image; a contrast component derivation unit that derives a contrast component based on a contrast value between a pixel of the reflectance component image and a peripheral area of the pixel; a histogram derivation unit that derives a luminance histogram of the grayscale image weighted according to the contrast value for each pixel of the contrast component; a conversion function derivation unit that derives a luminance conversion function for converting a luminance such that a luminance histogram of a converted grayscale image in which the grayscale image is converted by the luminance conversion function and a predetermined histogram are matched with or similar to each other; and a luminance conversion unit that generates the converted grayscale image.

A video-based monitoring and image post-processing system may include a plenoptic camera that has multiple mirrors in its field of view. The plenoptic camera may capture four-dimensional light-field information for multiple images of its field of view and may embed that information in image data sent to a local or backend server for post-processing. An image processing application on the server may extract image data for pixels that collectively represent one of the mirrors, and apply a focusing operation on the extracted image data to generate a video stream of a virtual camera represented by the mirror, dependent on the image information and the distance between the mirror and the camera. The application may correct distortions due to the curvature of the mirror. The system may provide video monitoring in areas without a single line of sight without the need for a large number of expensive cameras.

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 the 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.

Embodiments relate to determining characteristics of a display panel by using capturing images through multiple filters where the multiple filters include at least two filters that collectively enable replicating of a color matching function. At least two filters of the multiple filters have transmission profiles that correspond to the same color matching function (x color matching function) in different wavelength ranges. Image capturing devices capture the display panel through respective filters. The captured images are processed to the display characteristics of pixels or regions of the display panel.

Color calibration of color image rendering devices, such as large color displays, which operate by either projection or emission of images, utilize internal color measurement instrument or external color measurement modules locatable on a wall or speaker. A dual use camera is provided for a portable or laptop computer, or a cellular phone, handset, personal digital assistant or other handheld device with a digital camera, in which one of the camera or a display is movable with respect to the other to enable the camera in a first mode to capture images of the display for enabling calibration of the display, and in a second mode for capturing image other than of the display. The displays may represent rendering devices for enabling virtual proofing in a network, or may be part of stand-alone systems and apparatuses for color calibration. Improved calibration is also provided for sensing and correcting for non-uniformities of rendering devices, such as color displays, printer, presses, or other color image rendering device.
