<p>PROBLEM TO BE SOLVED: To provide an imaging device and a wireless communication terminal capable of performing high-speed, high-accuracy focal adjustment.SOLUTION: An imaging device includes: an auxiliary light-emitting unit (40); a frequency switching unit (27); a first AF evaluation-value generation unit (251); a third AF evaluation-value generation unit (253); a focused-position calculation unit (29); and lens driving means (14, 15, 30). The auxiliary light-emitting unit (40) emits auxiliary light having an auxiliary light frequency band onto an object. The frequency switching unit (27) determines the auxiliary light frequency band based on a focal length of a lens (11). The first AF evaluation-value generation unit (251) generates a first AF evaluation value. The third AF evaluation-value generation unit (253) selects a third spatial frequency band based on the auxiliary light frequency band, extracts the third spatial frequency band from an imaging signal, and generates a third AF evaluation value. The focused-position calculation unit (29) calculates a focused position based on the first AF evaluation value and the third AF evaluation value.</p> |
