US Patent:

7248284, Jul 24, 2007

Filed:

Aug 8, 2003

Appl. No.:

10/636738

Inventors:

Edward Alan Pierce - North Potomac MD, US

International Classification:

H04N 17/00
H04N 17/02

US Classification:

348188, 348187, 348175, 34820812

Abstract:

Calibration targets for use with digital cameras comprise black and white target areas to which digital cameras are exposed simultaneously to provide proper settings for highlight and shadow sensitivity prior to making a digital photograph. In addition a white or gray neutral target area, without color bias, is provided, to which the digital cameras are exposed to provide desired settings for color balance prior to making digital photographs. In one embodiment of the calibration target, the black and white target areas are on one side of a panel and the white or gray neutral target area is on the other side of the panel. In accordance with methods of calibrating digital cameras and to methods of photography, the image of the black and white target areas is adjusted by viewing a histogram display thereof and adjusting exposure settings until spikes in the histogram representing black and white detection are equally balanced between boundaries with no lateral offset.

International Classification:

Abstract:

Digital cameras are calibrated so that detailed highlights and shadows in scenes being photographed are reproduced in digital images of those scenes by calibrating holographic data obtained from target images at those scenes. In one embodiment the target image is obtained from an actual target having black and white, and optionally gray, target areas; and in another embodiment, the target image is obtained from the scene being photographed. In both embodiments, histographic data is manipulated so that shadow and highlight data spikes are automatically placed in boundary areas by automatically adjusting lens aperture and/or shutter speed prior to taking the desired photograph of the scene. The resulting photograph is adjusted for highlight and shadow details.
