To provide a light emission intensity adjustment device which performs light emission intensity adjustment for turning an existence object range of a driver and an existence object range of an occupant in a front passenger seat into a proper illumination state in accordance with the state of brightness in a vehicle.SOLUTION: A light emission intensity adjustment device comprises: an occupant detection unit 12 which detects whether or not a driver exists and whether or not an occupant in a front passenger seat exists on the basis of a photographed image; a target luminance setting unit 13 which sets a first target luminance value set by assuming that a main occupant exists for a target luminance value within a main occupant face range in the photographed image when the occupant detection unit 12 detects that the main occupant exists, and sets a second target luminance value set by assuming that the main occupant does not exist for the target luminance value within the main occupant face range when the occupant detection unit 12 detects that the main occupant does not exist but a sub occupant exists; a luminance measurement unit 14 which measures a luminance value within the main occupant face range on the basis of the photographed image; and an adjustment unit 15 which adjusts the light emission intensity of an illumination unit 101 on the basis of a difference between the target luminance value and the luminance value within the main occupant face range.SELECTED DRAWING: Figure 1

    【課題】車両内の明るさの状況に応じて運転者の存在対象範囲および助手席乗員の存在対象範囲を適正な照明状態とするための発光強度調整を行う発光強度調整装置を提供する。【解決手段】撮像画像に基づき、運転者が存在するか否か、および、助手席乗員が存在するか否かを検知する乗員検知部12と、乗員検知部12が、主乗員が存在すると検知した場合、撮像画像における主乗員顔範囲の目標輝度値に主乗員が存在することを想定して設定された第1目標輝度値を設定し、乗員検知部12が、主乗員が不在であり、かつ、副乗員が存在すると検知した場合、主乗員顔範囲の目標輝度値に主乗員が存在しない状態を想定して設定された第2目標輝度値を設定する目標輝度設定部13と、撮像画像に基づき、主乗員顔範囲の輝度値を測定する輝度測定部14と、目標輝度値と主乗員顔範囲の輝度値との差分に基づき、照明部101の発光強度を調整する調整部15とを備えた。【選択図】図1
