A method includes capturing images with an image sensor while switching the shutter speed of the image sensor between a first speed and a second, higher speed. When a captured subject is a barcode, a barcode image is obtained when the shutter speed is the first speed, and barcode information is obtained by decoding the barcode in the image. When a captured subject is a light source, a bright line image including bright lines corresponding to a plurality of exposure lines included in the image sensor is obtained when the shutter speed is the second speed, and a visible light signal is obtained as visible light information by decoding a pattern of the bright lines in the obtained bright line image. The method also includes displaying an image obtained through capturing performed when the shutter speed is the first speed. |
