Claim Text:
1. A method of calibrating automatic white balance in an image capturing device including a first image sensor and a second image sensor, the method comprising: generating first frame data and second frame data using the first image sensor and the second image sensor, respectively, in response to incident light while the first image sensor and the second image sensor are turned on; generating first color temperature estimation information and second color temperature estimation information based on the first frame data and the second frame data, respectively; determining whether an amount of the first color temperature estimation information is sufficient to estimate a color temperature of a light source; estimating the color temperature of the light source based on the first color temperature estimation information in response to determining that the amount of the first color temperature estimation information is sufficient; estimating the color temperature of the light source based on the first color temperature estimation information and the second color temperature estimation information in response to determining that the amount of the first color temperature estimation information is insufficient; and adjusting the first frame data based on the estimated color temperature.
