Document Type and Number:
Japanese Patent JP5659623
Kind Code:
B2
Abstract:
In an example embodiment, a calibration module in a projector platform establishes an initial configuration of settable exposure attributes for a digital camera. The calibration module projects a preview image onto a surface and captures the projection of the preview image with the digital camera and receives input from a user identifying regions of interest in the capture of the preview image. Next the calibration module projects an exposure image onto the surface. The calibration module then computes a final configuration of exposure attributes for the digital camera by iteratively: (a) capturing the projection of the exposure image with the digital camera; (b) measuring descriptive statistics relating to the color channels of pixels in the regions of interest in the capture of the exposure image; (c) evaluating the descriptive statistics with an evaluation function determined by a calibration process; and (d) establishing a revised configuration of exposure attributes.
