Digital monochrome images contain a single hue, rather than recording the colors of the object that is photographed. It includes all forms of black and white which produce images containing tones of grey ranging from black to white.  The image gray values are typically divided into 256 shades for computer analysis. 

Digital color cameras generally use a Bayer Mask over a monochrome CCD. Each square of four pixels has one filtered red, one blue, and two green.  The result of this is that luminance information is collected at every pixel, but the color resolution is lower than the luminance resolution.  The resulting image has 1/4 the pixel resolution of a monochrome image.  New better color separation can be reached by three-CCD devices (3CCD) and a dichroic beam splitter prism, that splits the image into red, green and blue components.

High resolution cameras contain sensors with larger number of pixels which provides increased accuracy for inspections.  Generally a camera with over one megapixel (1Mpx) is considered high resolution.

High speed cameras are designed to capture images of moving objects.  Generally a camera that performs over 80 frames per second (fps) is considered high speed.
