[Image Processing Engineer Column] Guaranteed Operation Time

Depending on the application, there are image processing tasks that cannot be "used" unless the operational time guarantee is strictly adhered to. I will introduce two further types of "operational time guarantees."
Example 1: Inspection Equipment Application
If the processing is not completed within the manufacturing tact time of the production line, the next inspection target cannot be inspected. However, the delay time from when the image data is input until the result is produced does not need to be within the tact time. Delays up to the mechanism that rejects the result are acceptable. By skillfully utilizing this "acceptable delay" and adhering to the principle of "guaranteeing a fixed delay time," implementation costs can be reduced compared to Example 2.
Example 2: Collision Prevention
It may be easier to explain something like automatic brakes. Since it is a collision prevention brake, the faster the time from detection to the judgment of "stop," the better. However, to translate this into catalog specifications, it needs to be paired with braking performance, so an operational speed guarantee is required as "maximum delay." In this case, even if it incurs higher costs than Example 1, speed is prioritized.
Since different performance requirements are demanded for the same terminology, understanding the requests is crucial, as discussed in this column.
