The borescope is a product often used to inspect the interior of metal machined products. There are instances where the contrast between light and dark may become pronounced due to the metal’s machining state, R-value, and surface irregularities. In such cases, employing a wide dynamic range camera may enhance visibility. We compared our general-purpose video camera (GR-i700) with the high-sensitivity, wide dynamic range high-definition camera (BA200HD) adopted for borescope applications.

When there are irregularities such as R-values or surface imperfections in the metal parts, there tends to be an increase in halation areas and darkened regions. Utilizing a wide dynamic range camera broadens the observable range. As illustrated above, the range of observation for the threaded portion deep inside, which was difficult to observe with conventional video cameras, has expanded.
