2.10.6 Basic Functions
(1) Imaging capture
This function captures image data. It outputs two-tone of 256-level grayscale as image data. When
used together with a JPEG library, it can save captured images as JPEG files. Resolution can be
lowered for output by downsampling the image.
At that stage, the image sizes are as follows.
Function Image size

x1/1, x1/2, x1/4
When x1/1 is
specified
832×640 pixels
When x1/2 is
specified
416×320 pixels
When x1/4 is
specified
208×160 pixels
When x1/5 is
specified

(2) Signature Index Function
This function scans both symbol and signature at one time and outputs the symbol data and
indexed signature at the same time. The position and size of a signature can be specified in the user
application based on the position of the symbol.
The function automatically corrects the up and down positions of the captured symbol in
correspondence with the up and down positions of the image data even if it has been captured
upside down or diagonally, and then outputs it.
As described above, clip out the area at the position relative to the symbol center, and output it as
an image file.
