5.Auto shutter control and absolute value shutter control
The auto shutter control function cannot be used in the Absolute value control mode. When Shutter is set to AUTO, the Absolute value control mode is automatically canceled.
6.Issues to be considered with partial activation, and binning
With partial activation and binning,
If strong light comes into the image at the same time, there may be some influence at the edges of the image. In such a case then, adjust the lens so that only the appropriate amount of light is allowed.
7.About the address range available for BlockWrite operations
The camera performs BlockWrite operations against consecutive registers. However, the range of the addresses stored in these registers are limited.
Available address ranges for | Functions | |
BlockWrite operations | ||
| ||
|
| |
F0F00600h - F0F00614h | Frame rate/Video mode/Video | |
| format/Isochronous channel/ | |
| Isochronous speed/ | |
| Isochronous_Enable | |
|
| |
F0F00800h - F0F008fCh | Feature control | |
|
|
If BlockWrite operations are performed outside the ranges listed above, an address error will occur.
Meanwhile, the camera can perform BlockRead operations for any sequence of consecutive registers even though the registers are not available for BlockWrite operations.
In Format 7 CSR, for example, BlockWrite operations are prohibited because Format 7 CSR requires a process for setting the register. However, BlockRead is possible in Format 7 CSR.
Appendix
8. Note on the isochronous control register
The BlockWrite operations are available in the range F0F00600h to F0F00614h. However, setting the video mode in this range is not recommended because it may influence the variable range available for the features. Following the process listed below is recommended for setting the isochronous control register.
Set the isochronous channel/isochronous speed
| (F0F0060Ch) |
Set the video format | (F0F00608h) |
Set the video mode | (F0F00604h) |
Set the frame rate | (F0F00600h) |
Confirm the variable range for the various features
Set the features (as needed)
Video start | (F0F00614h) |
9.About the Binning mode on the
On a camera using a color CCD, the color information is lost during the process of mixing pixels. Because of this, a color CCD camera cannot output a correct image in the Binning mode. Use the Binning mode only when you intend to perform something needing a high frame rate, such as focus adjustment.
