Sensor

•Long exposure times will increase the number of hotpixels.

•For long time exposure a maximum value of 5 seconds is possible. With longer exposure times the image quality is inadequate.

•High temperatures will increase the black level of individual pixels.

•Vertical subsampling should not be used because it can cause corrupted images. The reason it is still supported by the driver is to ensure downward compatibility.

Driver versions earlier than 3.30 allow setting an AOI height of less than 256 pixels for UI-225x cameras. An AOI height <256 pixels should be avoided, however, as it increases the camera's current consumption.
