UV-VIS Camera

In camera imaging systems, frame rate and exposure time are two of the most fundamental and mutually influential parameters. A high frame rate camera necessarily has a short exposure time, and an excessively long exposure time will inevitably lead to a lower frame rate. This article will analyze the decisive influence of exposure time on frame rate and explore balancing strategies in practical applications. I. Frame Rate and Exposure Frame rate (fps): The number of image frames a camera captures and outputs per second. The frame rate directly reflects the speed at which the camera captures information. Frame period: The time occupied by each frame, equal to 1/frame rate. A frame rate of 30 fps corresponds to a frame period of approximately 33.33 ms. Exposure time: The duration during which the photosensitive elements of the image sensor collect photons, typically ranging from a few microseconds to several seconds. A complete frame acquisition cycle generally includes: exposure, readout, reset, and preparation for the next frame. Among these, exposure time is only a part of the cycle. II. The Effect of Exposure Time on Frame Rate If the exposure time is greater than the reciprocal of the camera's maximum frame rate, the…
