Abstract
An imaging apparatus is disclosed. The apparatus includes: a solid-state imaging device provided with a plurality of arranged light-sensitive devices each having sensitivity to light in a range from a visible region to an infrared region; a first filter for transmitting light in the visible region to a first part light-sensitive device out of the plurality of light-sensitive devices; a second filter for transmitting light in the infrared region to a second part light-sensitive device out of the plurality of light-sensitive devices; and a signal processing section for changing a ratio between an electrical signal converted by the first part light-sensitive device and an electrical signal converted by the second part light-sensitive device used as an electrical signal used for deciding exposure in accordance with intensity of the electrical signal converted by the first part light-sensitive device.
