UPDATING AN EXPOSURE TABLE OF AN IMAGE SENSOR

摘要

A method, a system, and computer program product for updating a current exposure table that is used by an image sensor in order to prevent alternating current (AC) frequency banding due to incandescent or fluorescent lights in a camera preview, a captured video, and/or captured still images. The method includes detecting a condition that triggers an update to a current exposure table that is used by at least one image sensor of a device. A suitable exposure table for potential use by the at least one image sensor is then determined. The suitable exposure table is then evaluated to determine whether the suitable exposure table is equivalent to the current exposure table. In response to determining the suitable exposure table is not equivalent to the current exposure table, the suitable exposure table is applied to the at least one image sensor.
