摘要： A digital camera includes a lens and a plurality of color filters adjacent the lens. An array of detectors such as CCDs each receive, through the lens and a corresponding one of the color filters, light reflected from a scene. Each detector outputs a signal representative of an amount of light it receives. Circuitry is connected to the array for processing the signals from the detectors and generating a set of digital image data including a chromaticity value and a luminance value of a plurality of pixels representing an uncorrected image of the scene. A control circuit maps a two-dimensional representation of the digital image data into a two-dimensional representation of a set of reference image data and adjusts selected ones of the values of the set of digital image data in accordance with a predetermined transform to white balance the uncorrected image of the scene and produce a modified set of digital image data representing a corrected image of the scene.

摘要： A digital still camera is used for taking and storing digital representations of a plurality of images. A printer, such as an ink jet printer or a laser printer, is used for generating graphical representations of selected ones of the plurality of images on a preselected print media such as a paper. A flash memory card, floppy diskette, direct data link or some other data transfer scheme is used to transfer the digital representations of the plurality of images from the digital still camera to the printer. The printer includes programming for generating a combination proof sheet and order form. The combination proof sheet and order form can include an array of thumbnail images and a plurality of image selection and/or image enhancement user designation areas such as bubbles to be filled in by the user with a pencil. The printer includes a scanner and related circuitry and software for scanning the combination proof sheet and order form to detect the user designation areas completed by the user. The programming in the printer thereafter causes it to generate at least one final print sheet with the images and enhancements designated by the user on the combination proof sheet and order form. The proof sheet and order form can be used to designate the number of final prints of a selected image, the size and/or cropping of the prints, the brightness, color balance, background, borders and so forth.

摘要： A color printer receives P, N-bit values indicating a computer generated color to be printed, there being 2.sup.NP possible combinations of bits in the P, N-bit color values. Each N-bit value has a least significant bit (LSB). Upon receiving P, N-bit color values, the color printer creates an address from P combined multiple-bit segments of each of the received N-bit values, each multiple bit segment excluding at least a LSB of each N-bit value. The color printer includes a cache memory having substantially less addresses than 2.sup.NP, each cache address including first and second entries, a first entry being P values indicative of a computer generated color and a second entry being P values usable by the color printer to reproduce the first entry. A processor determines if there is a match at an address created from a received computer color value between a first entry and the received computer color value, the match disregarding an LSB of each N-bit value comprising the first entry at the address. The processor is responsive to a determined match to access the second entry at the address and to employ the second entry to control the color printer. Exclusion of the LSB's in determination of the presence of a match enables a substantially greater probability of finding such a match in the cache memory.

摘要： A color display screen displays a calibration color patch and a comparison color patch. The calibration color patch manifests a calibration color of a predetermined intensity, and the comparison color patch manifests a comparison color derived from a user determined input value. The system is controlled by a processor and is responsive to a user's indication of a perceived color match between a calibration color patch and a comparison color patch, to determine a transfer function that enables conversion of a value that generated the comparison color to a value assigned to the calibration color. The processor is further responsive to further perceived color matches of first and second color patches with first and second different intensity calibration color patches, respectively, to determine if first and second transfer functions determined for the first and second comparisons are within a transfer function threshold value of each other. If they are, the transfer functions are averaged and employed to calibrate colors transmitted to an attached color printer. If they are not within the transfer function threshold value, an additional comparison test is made. If the resulting transfer function is not within the threshold value, a default color transfer function is substituted.
