Method for encouraging acceptable illumination for using a tethered PC camera

Disclosed is a method for encouraging acceptable illumination for using a tethered PC camera. Benefits include improved functionality.

Description

              The disclosed method includes two components. The first part is an algorithm that monitors the light level in the scene. If the light level falls below a preset or perhaps user-defined level where there is insufficient light to maintain acceptable image quality, the second component is activated. It includes a dialog box (see Figure 2) that is displayed on-screen when the low-light trigger level is reached.

Advantages

              Conventionally, when the level of light is low and image quality has degraded to an unacceptable level, no intervention with the user is provided on cameras.

              As PC camera technology moves away from CCD sensors to CMOS sensors, light levels become much more important. CMOS sensors inherently produce more noise in low light than CCD sensors.
