    Abstract: In the present invention each input pixel value is compared against a randomly selected threshold value to provide an output pixel having a value indicative of which of the values is greater. The threshold value is selected from one of a plurality of threshold matrices, each having a predetermined number of threshold values that are arranged in a pattern with the values for a base matrix being increased by an increment for each succeeding one of the plurality of threshold matrices. The selection of the one threshold matrix is made by means of a pseudo-random number generator.

    Abstract: A method for reducing banding artifacts for bi-directional multi-pass printing on an inkjet printer utilizing a printhead with a plurality of ink nozzles includes defining different print masks to be used for leftward and rightward printing passes such that both the order of ink laydown and the timing between ink laydown on different passes are each substantially constant for a given horizontal position within the image, independent of the vertical position within the image; and printing an input image on the inkjet printer with the defined print masks using a bi-directional multi-pass print mode.

    Abstract: A method for printing an input digital image using a digital printer having a set of colorants with substantially the same color but different densities, including a sequence of node points where each of the two or more colorants are either at their maximum or minimum values, setting colorant concentrations such that the color channel output responses corresponding to the sequence of node points are substantially equally spaced in a visually uniform color space; forming colorant control look-up tables to provide smooth transitions in the color channel output response between the sequence of node points; addressing the colorant control look-up tables with the printer code value for each pixel of the input digital image to determine the colorant control signals for each of the two or more colorants; and controlling the digital printer using the colorant control signals to produce a print of the input digital image.

    Abstract: 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.

    Abstract: 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.
