How to use the working mode settings in industrial cameras
Industrial cameras can be classified into line scan cameras and area scan cameras based on the structural characteristics of their sensors. The following is a brief introduction to the working modes of line scan cameras and area scan cameras.
1. Line Scan Camera Operating Modes:
1-1. Fixed Line Scan Rate Continuous Mode
a. Fixed line rate
b. The target object moves at a constant speed
c. The line scan rate depends on the frequency of the line synchronization signal
1-2. Variable Line Scan Speed Trigger Mode
a. Line trigger
b. Target object speed is variable
c. Line scan speed depends on the duration of the external trigger pulse
1-3. Variable line scan speed and variable frame size mode
a. Line trigger + Frame trigger
b. Target object's speed and size are variable
c. Line scan speed depends on the external trigger pulse duration
2. Operating Modes of Area Scan Cameras
2-1. Continuous Mode
a. Exposure time does not exceed transmission time
b. Frame rate remains constant and independent of exposure time
c. Internal exposure control
2-2. Pseudo-continuous mode
a. Exposure time can exceed transmission time
b. Frame rate equals the reciprocal of (exposure + transmission) time
c. Used when transmitting large amounts of data
2-3. Trigger Modes
a. Internal Exposure Control
b. External Trigger
c. Image Acquisition After a Delay
2-4. Asynchronous Reset Mode
a. Requires asynchronous operation mode
b. Obtains the current image without delay
c. The acquisition card sends the exposure signal to the camera.
2-5. Programmable Control Modes
a. External Exposure Control
b. Camera-Controlled Delay Time
c. Programmable Exposure Time Control
2-6. Long-duration integration mode
a. External or internal exposure control
b. Exposure time is longer than transmission time
c. Equivalent to multi-image accumulation, increasing brightness; commonly used in gel and darkroom operations.
