Abstract
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.
