### Camera Connection
1.    **Camera Type: Area Scan Camera, Line Scan Camera**
        *   **Area Scan Camera:** Like a regular phone/DSLR camera, it captures the entire picture instantly with a "click". It produces a complete 2D rectangular image.
        *   **Line Scan Camera:** Like a flatbed scanner or photocopier, it uses an extremely thin photosensitive line to scan the picture row by row from top to bottom, and then "stitches" each row of images together to obtain a complete 2D image.

2.    **Camera Serial Number:** If there are many cameras in the device list, you need to fill in the camera serial number here to bind successfully.
      * **Image Acquisition Mode: Read Image from Camera, Read Image from Disk**
        * **Read Image from Camera:** Select this mode for formal inspection.
              > In this mode, users can perform image control, hardware trigger control, and flash control based on the situation.
        * **Read Image from Disk:** If there is no real camera or for simulation debugging by developers, you can select this mode.
              > Selecting this mode will directly load all images in the folder on the hard disk into other parameter setting areas of the camera.
              > In this mode, there is no need to set image control, hardware trigger control, and flash control.

### Image Control
1.   **Image Resolution:** Original Resolution and Custom Resolution
      * Custom Resolution: Users can crop the image here![](/media/202602/2026-02-03_165442_8569410.46025451633905745.png)
      * Image Mirror: No Mirror, X Mirror, Y Mirror, XY Mirror![](/media/202602/2026-02-03_173304_0702150.5520411643637201.png)
        
### Hardware Trigger Control
1. Hardware Trigger Type: Rising Edge, Falling Edge, High Level, Low Level
> Core Basis: Intuitive Understanding of Level and Transition
> Low Level (L): IO port voltage is 0V (Signal "Disconnected / None" state);
> High Level (H): IO port voltage is 24V (Signal "Connected / Present" state);
> Transition: The instantaneous process of level changing from L→H or H→L (Non-continuous, just a time point);
> Continuous: The time period during which the level remains L or H unchanged (Status remains as long as it lasts).

* Trigger Mode: Self-Trigger, Software Trigger, Hardware Trigger
   >i **Trigger Mode Description:**
>
> Self-Trigger: In this mode, the camera automatically captures images, mostly used for projects requiring continuous photo inspection.
>
> Software Trigger: In this mode, the software needs to send a trigger command (Camera aGrabSave) to the camera first to capture an image.
>
> Hardware Trigger: This mode requires connecting the camera's IO trigger line, and the corresponding thread trigger mode must be set to self-trigger. The camera can only capture images when there is a set signal on the camera IO trigger line; for other wiring methods, please select Software Trigger.

* Gamma: Gamma adjusts the brightness display of the image by twisting the ratio of gray values to fit human eye perception or preserve original linear data for machine algorithms. Industrial camera gamma values generally support custom adjustment from 0.1 to 4.0, and some cameras preset common values (such as 0.45, 0.5, 1.0, 2.2). The core is divided into three cases: γ=1, γ<1, γ>1. Each value corresponds to a clear industrial usage scenario with no ambiguity.
| Gamma Value Setting | Core Mapping Effect | Image Visual Performance | Core Applicable Scenarios |
|------------|--------------|--------------|--------------|
| γ=1 (Default Linear) | Input = Output, no non-linear correction, retains sensor original linear gray data | Image is dark, shadow details are invisible to the naked eye, but gray value corresponds 1:1 to actual light intensity | Machine vision algorithm processing (defect detection, dimension measurement, positioning, OCR, gray analysis) — The most core usage scenario for industrial cameras |
| γ&lt;1 (e.g., 0.4/0.5/0.8) | Shadow gray values are amplified, highlight gray values are compressed (gray values in low brightness range are more dispersed) | Image is brightened overall, shadow details are clearly visible, highlight details are slightly lost | Human visual observation/monitoring (low light environment, manual inspection of shadow defects, observation of dark textures on metal workpieces) |
| γ&gt;1 (e.g., 1.2/1.5/2.2) | Highlight gray values are amplified, shadow gray values are compressed (gray values in high brightness range are more dispersed) | Image is darkened overall, highlight details are clearly visible, shadow details are slightly lost | Human visual observation/monitoring (strong light environment, high reflective surface, manual inspection of highlight defects, such as glass scratches, metal highlight area flaws) |
* Exposure Time: Sensor light reception duration, linearly controls brightness, directly affects motion blur. Set this parameter first for industrial debugging.
* Camera Gain: Gain is brightness compensation at the electrical signal level. It only amplifies existing signals (including noise) and does not increase the actual light received by the sensor; gain increases brightness but also noise/speckles, and reduces gray uniformity. Minimize use in industrial debugging. Prioritize exposure adjustment.
* Digital IO Output: Used with digital IO output module for testing.

### Simulation Mode, Preview Image, Light Source Control

The light source control here only applies when a real camera is connected. For simulation cameras, the parameter configuration here is invalid.
* Controller Selection: Supports 7 light source controllers.
* Trigger Mode: Always On, Software Trigger.
* Time Earlier Than Shooting: Set how many ms earlier than shooting to turn on the light source.
* Supports 8 light source channels, and the brightness of each channel can be set individually.
