Abstract
(EN) An imaging device according to the present disclosure is provided with an optical bandpass filter, an imaging element, a subtractor, a multiplier, an adder, a luminance matrix, and a luminance level determination unit. The optical bandpass filter transmits visible light and near-infrared light selectively. The imaging element outputs a first signal corresponding to the light-reception intensity of visible light and near-infrared light, and a second signal corresponding to the light-reception intensity of near-infrared light. The subtractor subtracts the second signal from the first signal and outputs a third signal. The multiplier multiplies the second signal by a control value and outputs a fourth signal of a signal level lower than or equal to that of the second signal. The adder adds the fourth signal to the third signal and outputs an image signal. The luminance matrix outputs luminance information of a visible region corresponding to the image signal. The luminance level determination unit supplies a control value of a value corresponding to the luminance level of the visible region to the multiplier on the basis of the luminance information.
(FR) Dispositif d'imagerie selon la présente invention pourvu d'un filtre passe-bande optique, d'un élément d'imagerie, d'un soustracteur, d'un multiplicateur, d'un additionneur, d'une matrice de luminance et d'une unité de détermination de niveau de luminance. Le filtre passe-bande optique transmet de la lumière visible et de la lumière proche infrarouge de manière sélective. L'élément d'imagerie délivre un premier signal correspondant à l'intensité de réception de lumière de la lumière visible et de la lumière proche infrarouge, et un deuxième signal correspondant à l'intensité de réception de lumière de la lumière proche infrarouge. Le soustracteur soustrait le deuxième signal du premier signal et délivre un troisième signal. Le multiplicateur multiplie le deuxième signal par une valeur de commande et délivre un quatrième signal d'un niveau de signal inférieur ou égal à celui du deuxième signal. L'additionneur additionne le quatrième signal au troisième signal et délivre un signal d'image. La matrice de luminance délivre des informations de luminance d'une région visible correspondant au signal d'image. L'unité de détermination de niveau de luminance fournit une valeur de commande d'une valeur correspondant au niveau de luminance de la région visible au multiplicateur sur la base des informations de luminance.
(JA) 本開示に係る撮像装置は、光学バンドパスフィルタ、撮像素子、減算器、乗算器、加算器、輝度マトリックス及び輝度レベル判定部を備える。光学バンドパスフィルタは、可視光及び近赤外光を選択的に透過させる。撮像素子は、可視光及び近赤外光の受光強度に応じた第1の信号と、近赤外光の受光強度に応じた第2の信号とを出力する。減算器は、第1の信号から第2の信号を減算して第3の信号を出力する。乗算器は、第2の信号に制御値を乗算して第2の信号の信号レベル以下の第4の信号を出力する。加算器は、第3の信号に第4の信号を加算して画像信号を出力する。輝度マトリックスは、画像信号に応じた可視領域の輝度情報を出力する。輝度レベル判定部は、輝度情報に基づいて、可視領域の輝度レベルに応じた値の制御値を乗算器に供給する。
