Objective information
Step 3
2D data
Scan direction
TM-XJ959A
This product captures 2-d image by scanning one
line repeatedly and continuously.
・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.
Step 1,2
【Example of scanning "2"】
Line scan
・Step 1: Sensor IC reads one line in red point-line area.
Transport
The size of the line in transport direction is based on the
direction
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.)
