Techniques for adjusting a projected image

摘要

Techniques are disclosed for compensating for deficiencies of a given image projector so as to eliminate or otherwise reduce discrepancies between original image data provided to the projector and the actual image projected by the projector. The techniques also may be used to enhance an attribute of the original image data to improve the image projected by the projector. The techniques can be implemented, for instance, with an imaging capture device and an image comparison engine. In operation, the imaging capture device can capture a projected image from a viewing surface, and the image comparison engine can compare the original image data with the projected image captured by the imaging capture device. Based on the results of this comparison, an adjustment then can be made to achieve the desired projected image. The adjustment may entail, for example, adjusting the original image data provided to the projector and/or adjusting projector settings.

主权项

1. An image comparison device comprising:
an image discrepancy module configured to compare projected image data with target image data, the projected image data resulting from an output of a projector; and an image output module configured to:
adjust at least one of original image data input to the projector and one or more control parameters of the projector, if the comparison by the image discrepancy module indicates a correctable discrepancy with respect to image color between the projected image data and the target image data, so as to reduce the correctable image color discrepancy; andoutput at least one of the adjusted original image data and the adjusted one or more control parameters to the projector.
