Abstract:
(EN) In the present invention, a transmittance estimation unit 11 estimates the transmittance in each area on the basis of an imaged image. The transmittance estimation unit 11 estimates a transmittance for each pixel using dark channel processing, for example. A transmittance detection unit 12 uses the transmittances estimated for each pixel by the transmittance estimation unit 11 and depth information for each pixel to detect the haze transmittance of the imaged image at the time of imaging. The transmittance detection unit 12 detects the haze transmittance on the basis of, for example, the logarithmic mean of the transmittances in the entirety or a prescribed part of the imaged image and an average depth value indicated by the depth information. Alternatively, the transmittance detection unit 12 may convert the gradation of the transmittance estimated for each area on the basis of the imaged image into the gradation of the depths indicated by the depth information for each area and use the transmittances after gradation conversion as the haze transmittances. The present invention makes it possible to accurately detect transmittance.
(FR) Selon la présente invention, une unité d'estimation de transmittance (11) estime la transmittance dans chaque zone en fonction d'une image imagée. L'unité d'estimation de transmittance (11) estime une transmittance pour chaque pixel à l'aide d'un traitement de canal sombre, par exemple. Une unité de détection de transmittance (12) utilise les transmittances estimées pour chaque pixel par l'unité d'estimation de transmittance (11) et des informations de profondeur pour chaque pixel pour détecter la transmittance de flou de l'image imagée au moment de l'imagerie. L'unité de détection de transmittance (12) détecte la transmittance de flou en fonction, par exemple, de la moyenne logarithmique des transmittances dans la totalité ou une partie prescrite de l'image imagée et d'une valeur de profondeur moyenne indiquée par les informations de profondeur. En variante, l'unité de détection de transmittance (12) peut convertir la gradation de la transmittance estimée pour chaque zone en fonction de l'image imagée dans la gradation des profondeurs indiquées par les informations de profondeur pour chaque zone et utiliser les transmittances après conversion de gradation en tant que transmittances de flou. La présente invention permet de détecter la transmittance avec précision.
(JA) 透過率推定部11は、撮像画像から領域毎に透過率を推定する。透過率推定部11は、例えばダークチャンネル処理を用いて画素毎の透過率を推定する。透過率検出部12は、透過率推定部11で画素毎に推定した透過率と画素毎のデプス情報を用いて、撮像画像の撮像時における煙霧の透過率を検出する。透過率検出部12は、例えば撮像画像の全体または所定部分における透過率の対数平均値とデプス情報が示すデプスの平均値に基づいて煙霧の透過率を検出する。あるいは、透過率検出部12は、撮像画像から領域毎に推定した透過率の階調を領域毎のデプス情報が示すデプスの階調に変換して、階調変換後の透過率を煙霧の透過率とする。精度よく透過率を検出できるようになる。
