    摘要: A digital image capture device for use in capturing underwater digital images, comprising a watertight housing; an image sensor for capturing a digital image; an optical system for imaging a scene onto the image sensor; a means for sensing a pressure outside the watertight housing; and a processor. The processor performs the steps of determining a sensed pressure; capturing a digital image of a scene using the image sensor; using the sensed pressure to determine an indication of whether the digital image capture device is being operated underwater and selecting an underwater photography mode or a normal photography mode accordingly; processing the captured digital image according to the selected photography mode; and storing the processed digital image in a processor accessible memory.

    摘要: A method for selecting the level of color inconstancy of an output image produced on a digital color printer having a neutral ink and a plurality of color inks is disclosed. The method includes analyzing the distribution of input colors present in the input digital image to determine a color distribution metric related to the importance of producing output images having a reduced color inconstancy when the output image is viewed under a variety of image illumination spectra; selecting a color transform from a set of available color transforms designed to produce output images having different color inconstancy characteristics in response to the color distribution metric; processing the input digital image using the selected color transform to produce a transformed image having a selected level of color inconstancy; and printing the transformed image on the digital color printer to produce an output image having the selected level of color inconstancy.
