Minimizes variations in image brightness caused by differences in color and shape, enabling clear image capture
HDR Imaging Solution
Using HDR*, the system captures and combines multiple images with different brightness levels to reduce brightness variations caused by differences in color and shape, resulting in a clear image.
*HDR (High Dynamic Range): An image processing technique that combines multiple images with different brightness levels to create a clear image.
Application Example
- Surface inspection of workpieces, such as circuit boards, that contain components with varying heights and surface textures, resulting in significant brightness differences with conventional imaging.
- Observation of the End Face and Inner Surface of a Cylindrical Workpiece
Imaging Examples
Imaging Example: Substrate
The color and glossy areas of the workpiece, extracted from the Bright field and Dark field images, can be observed in a single image
Imaging Example: PVC Pipe
Foreign matter can be observed on both the edges and the inner surfaces
Application Example
We offer complete HDR inspection solutions combining cameras, lenses, and lighting control systems tailored to the inspection environment.
- Character recognition and foreign object inspection of moving workpieces
- Stable Image Acquisition for Robot Picking
Imaging Example: Substrate
By setting the exposure time individually for each of the four pixels in a 2 × 2 grid and capturing them simultaneously, images with a wide dynamic range of up to 120 db can be acquired
HDR Image Processing Using Line-Scan Cameras
High-resolution HDR imaging using a line scan camera
Imaging Example: 8K Line Scan Camera
High resolution enables detailed observation of enlarged images
