Objective measurements are important. Defining the level of performance a camera must actually achieve is equally as important. The ongoing revision of IEC 62676-5 expands the focus from just measurement methods to application-specific performance requirements for professional security cameras.
People rarely sit perfectly still during video conferences. They glance at a second screen, take notes, or briefly turn toward someone else in the room. For webcams, this presents a challenge: they must maintain consistent image quality and respond reliably when a face returns to view. But how can this behavior be measured objectively?
Objective image quality measurements rely on dependable references. Yet while cameras, lighting systems, and test setups are regularly checked, one important factor is often overlooked: the test chart. Reference charts age over time and the aging process can affect the validity of measurement results. You can find the recommended replacement date on the back of your test chart.
