m

maximum pixel depth

This option enables higher bits per pixel when the scan is sent to the software. When it is off, 8 bits per pixel are returned for grayscale and 24 bits for color. When it is turned on, 16 bits per pixel are returned for grayscale and 48 bits for color.

midtones

The gray shades of an image. Midtones are usually between 30% and 70% black. Midtone control adjusts the brightness of gray levels in the image so that the lightest and darkest portions of the image can be properly displayed on your monitor. The higher the setting, the brighter the image appears on your monitor.

moiré

An undesirable pattern in color printing that results from incorrect screen angles of overprinting halftones. Moiré patterns usually result when you scan a halftone, when you scan images taken directly from a magazine, or when you scale an image in an image editor after it is scanned.

n

negative holder

This XPA piece holds negative strips for scanning. Insert it into the slide holder on the bottom of the XPA light source for proper scanning of negatives.

Back to TOC

negative light shield

This XPA piece blocks excess illumination and improves image quality when scanning negatives. Slide it into the negative holder after the chosen negative strip.

negative template

The cutout that comes with the optional transparency adapter that is placed on the scanning glass. Negatives are then placed in the template.

noise reduction

This option reduces the noise (unwanted specks) in an image by applying software algorithms to minimize the effects of noise in the scanner electronics.

o

OCR

See optical character recognition.

optical character recognition

Abbreviated OCR. A technology that recognizes letters in a scanned image and converts them into ASCII characters, or editable text.

optical resolution

The true resolution of a scanner, the resolution at which the scanner captures images. See also: interpolated resolution, resolution.

optimized palette

A palette or color table that contains the pixel colors present in an image.
