Gamma p, Threshold p | Canon FS 2710 specification

Gamma (p. 56)

Gamma allows you to enhance the overall image. Use Gamma adjustment when the color of the original does not match the color of the displayed image. You can use Gamma with the following types of files: 8-bit grayscale, 12-bit grayscale, 24-bit color and 36- bit color.

Threshold (p. 58)

Threshold adjusts the brightness of an image by digitizing it i.e. determining which gray pixels become black and which become white. You can use Threshold only with a monochrome document.

Color Correction Dialog Box

Save — Saves the image with the specified file name and color correction attributes. Load — Loads the image with the specified color correction attributes.

Reset — Resets every feature with its default setting.

Displays the RGB values of the part of the image currently under the mouse cursor and

frame in the Preview window. In the dual value display [XXX/YYY], the first part (XXX)

shows the setting after correction and the second part (YYY) shows the value of the current setting in the Preview window. When the image is a 36-bit color image, the values express 8-bit values for each color.
