Binarization (Sophisticated Labeling+)

When a monochrome camera is connected, the 256-tone grayscale images taken in from the camera are converted into binary black-and-white images before the images are measured.Converted white pixels are measured.
This specifies the level for converting grayscale images into binary images.

In the "Item tab" area, tap [Binary].

In the "Binary kind setting" area, set the type of binarization.

Setting item	Set value [Factory default]	Description
Binary kind	[Binary]	Convert 256-grayscale images to binary images.The binary level that is the conversion threshold is held constant.
Binary kind	Dyn threshold	The binary level is not held constant.Stable binary images can be obtained by taking the difference between the input image and that input image after it has been subject to brightness averaging. This option is effective when the lighting is unstable.

In the "Binary setting" area, specify the reference density range.

When binarization is selected

Setting item	Set value [Factory default]	Description
Binary level	0 to [255]	Specify the level for converting 256-tone grayscale images to binary images.Adjust the binary level so that the measurement object is converted to white pixels.You can also set the binary level so that only intermediate density is measured.
Automatic	－	Optimum binary levels are calculated automatically and set.
Reverse	Checked [Unchecked]	This item reverses black and white colors.

When Dyn threshold is selected

Setting item	Set value [Factory default]	Description
Extraction offset value	0 to 127 [5]	This sets the offset for the difference between the input image and that input image after it has been subject to brightness averaging.The higher this value, the easier it is to extract locations (such as edges) with large density difference.
Reverse	Checked [Unchecked]	This item reverses black and white colors.

Perform the [Advanced setting] if required.

Setting item	Set value [Factory default]	Description
Threshold region	[Light] Dark Equal Not equal	Set the region to extract. Light: Pixels brighter than the pixels around them are treated as white pixels. Dark: Pixels darker than the pixels around them are treated as white pixels. Equal: Pixels with minimum density difference from the pixels around them are treated as white pixels. Not equal: Pixels with large density difference from the pixels around them are treated as white pixels.
Filter Size	3 to [255]	Specify the filter size for brightness averaging processing.Match this size to the size of the location you want to extract.
Extraction offset value	0 to 127 [5]	This sets the offset for the difference between the input image and that input image after it has been subject to brightness averaging.The higher this value, the easier it is to extract locations (such as edges) with large density difference.
Reverse	Checked [Unchecked]	This item reverses black and white colors.
