Abstract	The method of automatically controlling exposure suggested in this paper can be divided into two stages: One is to construct a table storing values to establish an image sensor, and the other one is to control exposure by using the table created and actually establishing the sensor. To control exposure generally, it is possible to get an expected result by controlling analog/digital gains or exposure time. after constructing set values of the exposure control parameter, analog gains and exposure time, proper for each situation in the table in advance, it is possible to reduce computing amount by actually outputting the data stored in the table during the process of controlling exposure and setting the sensor.
