Acquiring a data of one line in scan direction.
・
Relative transport in transport direction between the
object and this product can accumulate 2 dimensional data.
Refer to left side of the drawings.
【
Example of scanning “2”
】
・
Step 1: Sensor IC reads one line in red point-line area.
The size of the line in transport direction is based on the
size of pixel.
・
Step 2: The scanning line is transported in transport
direction.
・
Step 3: Repeating Step 1 and 2 generates 2D image data.
(The height of the 2D-data means the strength of CIS
output.)
