Notes on sensor hotpixel correction on the UI-124x/UI-324x/UI-524x

If sensor hotpixel correction and Multi AOI are enabled, the sensor displays a four pixel wide black line between the AOIs.

Hotpixel

This function corrects the sensor hotpixels specified in the camera EEPROM.

•Mark hotpixel
If you select this check box, the hotpixel positions stored in the camera are graphically represented in the image.

•Hotpixel correction
Select this check box if you want to enable a software-based hotpixel correction.

•Sensor hotpixel correction
Enables the sensor's internal hotpixel correction for some models.

Test image

The camera transmits a selectable test image that you can use for testing the data transmission. You can choose from different types of test images, depending on the camera type.

•Selection
Some of the test images (e.g. Black image and White image) are created by the sensor and are available in both, USB-based and GigE-based uEye models.
With all GigE uEye HE cameras (CMOS and CCD sensors) you can also choose moving and stationary test images that are created by the camera hardware (e.g. Colored wedge, Animated line, Coldpixel/Hotpixel grid).
Test images marked (RAW) are only properly displayed in raw Bayer mode (see Color).

•Parameter value
You can adjust the appearance of some of the test images with the "Parameter value" slider.

Hinweis

Notes on test images

•Manually changing the pixel clock will disable the test image mode.

•Animated test images are ideal for testing recorded sequences.

•With some sensors, the sensor gain setting has an influence on the test image.

•For USB cameras, you can use a white test image to check the camera's maximum load on the USB bus. Due to the transmission process, completely white camera images require somewhat more bandwidth on the USB bus than completely black images.

•To turn on hotpixel correction does not make sense for a test image.

Edge enhancement

•This function activates a software filter that emphasizes the edges in the image.
Enabling the edge enhancement function increases the CPU load during image capture.

I2C

This function is available on a number of uEye board-level cameras. It allows reading and writing data via the I2C bus.

•Hexadecimal
Select this check box if you want to enter addresses and data in hexadecimal format. If the check box is disabled, the data needs to be entered in binary format.

•16 bit data
Select this check box to send data at 16 bit width.

•Device address (8 bit)
Address of the I2C device to be accessed.

•Register address (8/16 bit)
Address of the register to be read or written.

•Read
Data to be read from the register.

•Write
Data to be written to the register.
