HBVCAM OV9281 1MP HD  Black and White Globe Exposure CMOS Camera Module

Global Shutter:Global exposure: also known as frame exposure, global shutter As the name implies, when the shutter is opened, all light rays impinge on the entire surface of the chip at once, and then the shutter closes again.

In this case, "global" refers to simultaneous exposure of the entire surface, capturing the entire image area at once. In other words, under global exposure, all pixel exposure times are synchronized from start to end.

Rolling shutter exposure: also known as line exposure, rolling shutter, and rolling shutter .Under roller shutter exposure, all pixels do not start and end exposure at the same time, but instead proceed in rows

Advantages and disadvantages of both

(1) The advantage of global exposure is that all pixel points are exposed simultaneously. The disadvantage is that the exposure time is limited and there is a mechanical limit to the minimum exposure time.

(2) The advantage of roller shutter exposure is that it has a smaller exposure time. The disadvantage is that the image is exposed at different times line by line, and if the image is moving, there is significant drag. Therefore, roller shutter exposure is not suitable for photographing moving objects.
