IDS peak 2.8.0 / uEye+ firmware 3.33
The host functions allow you to make advanced settings that are performed directly on the host, such as flipping or hot pixel correction.

Fig. 223: Host features
Converting images
In the upper part you set the conversion of the pixel format, i.e. besides the source and target pixel format you also set the conversion mode (see Image Color Formats (PixelFormat) and Converting images).
•Fast: Conversion mode optimized for minimum processing effort with slightly lower quality.
•HQ (HighQuality): Conversion mode optimized for quality, with slightly higher processing effort.
•Classic: Conversion mode with compatibility to uEye camera models. In terms of speed, comparable to "Fast".
Image transformations
Under "Image Transformations", you can flip or rotate the displayed image.
•
Flips the displayed image on the vertical axis.
•
Flips the displayed image on the horizontal axis.
•
Rotates the displayed image 90° to the left (counterclockwise).
•
Rotates the displayed image 90° to the right (clockwise).
•
Resets all settings.
Hot pixel correction
The adaptive hot pixel correction can detect and correct hot pixels dynamically while the application is running. The method is "adaptive" because the pixel values are effectively adjusted to match surrounding pixels in terms of direction and intensity.

Note the following hints for adaptive hot pixel correction: •The adaptive hot pixel correction is performed on the host. •The adaptive hot pixel correction can only be used with RAW pixel formats. •Image pre-processing steps in the camera have an effect on hot pixel correction. •Subsequent image processing steps on the host, e.g. debayering, color correction, etc., do not have an effect on hot pixel correction. For example, if you flip the image in the camera (ReverseX/ReverseY) , you must redetect the hot pixel list afterwards. |
•Hot pixel correction
Enables the adaptive hot pixel correction in IDS peak. The adaptive hot pixel correction can determine hot pixels dynamically and correct them adaptively in the current image. Thus, hot pixels can be corrected better which, for example, result from an increased temperature.
•Display hot pixels
If this option is enabled, the found hot pixels are marked graphically in the image.
•Number of hot pixels found
Shows the number of hot pixels detected.
•Detect
Click this button to determine the number of hot pixels detected. The higher the intensity is set, the more sensitive the hot pixel correction reacts and the more defective pixels are found.
•Intensity
Sets the value for the sensitivity of the adaptive hot pixel correction: 1 (lowest sensitivity) … 5 (maximum sensitivity).
Gamma
Here, you can set the gamma value of the gamma correction. The gamma correction adjusts the camera characteristic curve to a typical display characteristic curve by raising the gray values to the power of the inverse gamma value. Usually, sRGB colors with a gamma of 2.2 are assumed. A gamma setting of 1.0 preserves linear gray values.
Additional information: The human eye perceives differences in brightness with a logarithmic characteristic curve, which is often approximated in practice with a gamma characteristic curve. The brightness perceived by humans increases more steeply in dark areas and less steeply in bright areas.
Edge enhancement
Here, you enable a host function to emphasize edges in the image. Enabling the function increases the CPU load.
