9.2.5.4 Image Data Screen Size
Determine the size of image data to be received using the Screen Size setting
in the Transfer Image Data dialog. The 1/1 screen receives all the image data
on the processing screen. The 1/4 screen receives the image data on the
processing screen by thinning the data to 1/4. When 1/4 screen is selected,
time required for data transmission is reduced to 1/4 of the 1/1 screen thus
saving time.
The display size of the teaching panel differs by the screen size. Since the 1/1
screen is about 4 times larger in size than the 1/4 screen, it is not possible to
display everything on a low-resolution personal computer screen. In cases like
this, receive the image data by setting the screen size to 1/4 screen.
When the image data that has been saved is transmitted to the Controller, it is
possible to analyze the same image data. In this case, if image data to be
transmitted is on the 1/4 screen, the analytical result will be different from
before, since the image data is thinned to 1/4.
Note: If the number of possible colors displayed on the personal
computer screen is less than 256, some color errors may be
generated to the image data displayed on the teaching panel.
Although no particular operational problem will result, use a
personal computer screen having 65,535 (16-bit color) or more
colors that can be displayed to ensure correct color display.
9.2.6 Save Image Data As
The Vision Manager can save image data displayed on the teaching panel in a
bit map formatted file. When image data is received from the Controller, the
data image is displayed on the teaching panel. Select Save Image Data As to
save the image data sample.
<Ver.1.6 or later>
The Vision Manager can save image data set on the teaching panel by
selecting “Export”. If the process screen or the drawing screen is selected,
composite image data is saved.
Screen sizes are as follows.
Kind of screen Selection Size
1/1 screen 512 x 480
Process screen
1/4 screen 256 x 240
1/1 screen 640 x 480
Drawing screen
1/4 screen 320 x 240
9.2.7 Open Image Data
With Save Image Data As, the Vision Manager can read the image data saved
in the bit map format and display it on the teaching panel. By transmitting
image data displayed on the teaching panel to the Robot Controller, you can
analyze the sample image that has been saved.
