A method for providing an intensity or brightness measurement using a digital image-capturing device comprising: selecting a target area within a field of view of the image-capturing device, the target area containing pixels; determining the brightness of pixels in the target area; accumulating the brightness values of the pixels in the target area; and determining a pixel value representative of the pixels in the target area. A device for making color measurements comprising an image-capture device, a processor or logic device, and a memory location for accumulating color data, and the processor or logic device is programmed to perform color measurements by accumulating the data for pixels located in the target area in memory, and determining a representative color value.

Method for collecting data for color measurements from a digital electronic image capturing device or system

A method for obtaining a target color measurement using an electronic image capturing device comprising the steps of: (1) determining one or more of a field correction array, level correction vectors, a color correction matrix, and a calibration correction and; (2) adjusting a target color measurement based upon one or more of a field correction array, level correction vector, a color correction matrix, and a calibration correction to obtain a corrected color target measurement.

Method for deriving consistent, repeatable color measurements from data provided by a digital imaging device

A method for providing an intensity or brightness measurement using a digital image-capturing device comprising: selecting a target area within a field of view of the image-capturing device, the target area containing pixels; measuring the intensity or brightness of pixels in a target area; accumulating the intensity or brightness values of the pixels in the target area; and determining a pixel value representative of the intensity or brightness of the pixels in the target area. A device for making color measurements comprising an image-capture device, a processor or logic device, and a memory location for accumulating color data, and the processor or logic device is programmed to perform color measurements by accumulating the data for pixels located in the target area in memory, and determining a representative color value.

A color measurement device comprising a means for electronically recording a digital color image, a target holder extending from the recording means having a distal end, and a target at the distal end of the holder, the target having one or more reference color regions thereon.

Method for using an electronic imaging device to measure color

A method and apparatus for engraving wherein the engraver includes a merge system for merging image data to be engraved in a manner which will reduce or eliminate 'halo' and/or 'ghost' images. The method utilizes a processor in an engraver for creating image data comprising continuous tone data and line work data. The method further involves the steps of locating transition data corresponding to where the continuous tone data and line work data meet; and processing at least some of the image data to provide processed image data using the transition data located in the locating step. The engraver has an engraving bed; a headstock and a tailstock located on the engraving bed for rotatably supporting a cylinder to be engraved; an engraving head located on the engraving bed for engraving the cylinder; an image data generator coupled to the engraving head, the image data generator being capable of creating image data comprising continuous tone data, line work data and transition data. The image data generator comprises a locator for locating the transition data and a processor associated with the locator for processing at least some of the image data to provide processed image data using the transition data located by the locator. The system and method facilitate selectively enhancing at least one edge or area within a data set, such as either a line work data set or a continuous tone data set, while selectively avoiding enhancing other areas, such as an area between a line work area and continuous tone area of an image.
