Image Sensor Transfer Controls
The Image Sensor Transfer Controls allow you to define at what row of the image sensor (CCD or CMOS) the image will begin to be transferred, and how many rows of the image sensor will be used to construct the image.
In-Sight vision systems capture all images using asynchronous reset and progressive scan; greyscale In-Sight vision systems produce 8-bit images, while color In-Sight vision systems produce 24-bit images. The image acquisition process begins within approximately 250 µs for all vision systems, and proceeds as follows:
- The image sensor integrates light for the duration of time specified by the Exposure Controls.
- The image accumulated in the image sensor is transferred, row-by-row, into a serial shift register.
- For every row transfer, the vision system clocks the shift register, pixel-by-pixel, out of the image sensor.
- The transfer begins at the Start Row and proceeds for the specified Number of Rows.
Start Row
Defines the first row to be transferred from the image sensor into memory on the In-Sight vision system:
| Resolution | Valid Start Row Values |
|---|---|
| 640 x 480 | 0 to 479 |
| 800 x 600 | 0 to 599 |
| 1024 x 768 | 0 to 767 |
| 1280 x 1024 | 0 to 1023 |
| 1600 x 1200 | 0 to 1199 |
| 2448 x 2048 | 0 to 2047 |
| 2592 x 1944 | 0 to 1943 |
Number of Rows
Defines the number of rows to be transferred into memory on the In-Sight vision system:
| Resolution | Valid Number of Rows |
|---|---|
| 640 x 480 | 1 to 480 |
| 800 x 600 | 1 to 600 |
| 1024 x 768 | 1 to 768 |
| 1280 x 1024 | 1 to 1024 |
| 1600 x 1200 | 1 to 1200 |
| 2448 x 2048 | 1 to 2048 |
| 2592 x 1944 | 1 to 1944 |
Note: If you will be connecting to an Emulator and want to view images from an In-Sight vision system that had acquired images with the partial image acquisition parameters enabled, set the Start Row and Number of Rows parameters of the Emulator to the same settings as those on the In-Sight vision system.
