We will introduce the ROI function of CIS cameras and its use cases that can be utilized for 3D inspection using light interruption methods and inspections that require high-speed takt.
The function that allows you to output only the necessary area from the images output by the camera is called ROI (Region Of Interest). By using the ROI function, it becomes possible to quickly read the necessary area, thereby increasing the achievable frame rate. This function is effectively utilized for 3D inspection using optical sectioning methods and inspections that require high-speed cycles. For customers considering 3D inspections or inspections that require fast processing, we will introduce the ROI function of our cameras and its application examples.

basic information
<ROI Utilization Example 1> Request: I want to secure about 100 pixels in the vertical direction and perform 3D inspection using a light sectioning method at high speed. Proposal: Use the ROI function to extract 100 pixels in the vertical direction for speed enhancement. - VCC-VCL5M (Effective pixel count 720 x 540 / Frame rate 523fps) → When the vertical resolution is reduced from 540 to 100 using the ROI function / Frame rate 2,101fps <ROI Utilization Example 2> Request: I want to capture long workpieces as quickly as possible. Proposal: Use the ROI function of a camera with a CoaXPress I/F that allows for high-speed transmission to extract only the necessary pixel count for speed enhancement. - VCC-25CXP1M (Effective pixel count 5120 x 5120 / Frame rate 82fps) → When the vertical resolution is reduced from 5120 to 480 using the ROI function / Frame rate 1,001fps For other utilization examples and details on the relationship between ROI settings and frame rates, please refer to the "ROI and Frame Rate Setting Examples" available for download from this page, or contact our sales department.
