IMAGING DEVICE AND ILLUMINATION CONTROL METHOD

PROBLEM TO BE SOLVED: To provide an imaging device that can illuminate a subject even when the distance from the imaging device to the subject varies, and suppress degradation of a pickup image.SOLUTION: An imaging device has an imaging unit having an imaging element 26, a zoom lens 22 and a first illumination unit (zoom illumination unit 23) for illuminating a subject, a mount table on which the imaging unit is mounted, a dome cover enclosing the imaging unit together with the mount table, a second illumination unit (wide illumination units 51A to F) which is disposed at the peripheral end portion of the mount table and illuminates the outside of the mount table, an information acquiring unit for acquiring instruction information for instructing the angle of view of the lens, and an illumination controller 58 for controlling a lighting angle of the first illumination unit 23 based on the instruction information. The illumination controller controls to turn out the first illumination unit and turn on the second illumination unit when the angle of view of the lens associated with the instruction information is larger than a predetermined angle, and also controls to turn on the first illumination unit when the angle of view of the lens associated with the instruction information is not more than the predetermined angle.SELECTED DRAWING: Figure 3 【課題】撮像装置から被写体までの距離が変化しても被写体を照明でき、撮像画像の劣化を抑制する撮像装置を提供する。【解決手段】撮像素子２６とズームレンズ２２と被写体に向かって照明する第１の照明部（ズーム照明部２３）とを備える撮像ユニットと、撮像ユニットが設置された設置台と、設置台とともに撮像ユニットを包囲するドームカバーと、設置台の周端部に配設され、設置台の外側に向かって照明する第２の照明部（ワイド照明部５１Ａ〜Ｆ）と、レンズの画角を指示する指示情報を取得する情報取得部と、指示情報に基づいて、第１の照明部２３による照射角を制御する照明制御部５８と、を備える。照明制御部は、指示情報に係るレンズの画角が所定角度より大きい場合、第１の照明部を消灯し、第２の照明部を点灯するよう制御し、指示情報に係るレンズの画角が所定角度以下の場合、第１の照明部を点灯するよう制御する。【選択図】図３
