Abstract:
(EN) Provided are an image processing device, an image processing method, and a program that enable highly accurate detection and correction of a defective block. An image processing device 20 is provided with: a defective block detection unit 22 which, on the basis of image data, detects an offset component of a pixel value generated in a shared block comprising a plurality of pixels sharing a readout circuit, by using the pixel value of a pixel within the shared block and the pixel value of a pixel outside the shared block; and a defective block correction unit 23 which, on the basis of the offset component detected by the defective block detection unit 22, calculates a correction amount for correcting the pixel value of at least one pixel within the shared block, and which corrects the pixel value of the at least one pixel within the shared block by using the correction amount.
(FR) L'invention concerne un dispositif de traitement d'image, un procédé de traitement d'image et un programme qui permettent une détection et une correction très précises d'un bloc défectueux. Un dispositif de traitement d'image (20) est pourvu : d'une unité de détection de bloc défectueux (22) qui, sur la base de données d'image, détecte une composante de décalage d'une valeur de pixel générée dans un bloc partagé comprenant une pluralité de pixels partageant un circuit de lecture, à l'aide de la valeur de pixel d'un pixel dans le bloc partagé et de la valeur de pixel d'un pixel à l'extérieur du bloc partagé ; et d'une unité de correction de bloc défectueux (23) qui, sur la base de la composante de décalage détectée par l'unité de détection de bloc défectueux (22), calcule une valeur de correction afin de corriger la valeur de pixel d'au moins un pixel dans le bloc partagé, et qui corrige la valeur de pixel dudit pixel dans le bloc partagé à l'aide de la valeur de correction.
(JA) 高精度に欠陥ブロックを検出して補正することができる画像処理装置、画像処理方法およびプログラムを提供する。画像処理装置20は、画像データに基づいて、読み出し回路を共有する複数の画素からなる共有ブロック内における画素の画素値と、共有ブロック外における画素の画素値とを用いて、共有ブロック内で生じる画素値のオフセット成分を検出する欠陥ブロック検出部22と、欠陥ブロック検出部22が検出したオフセット成分に基づいて、共有ブロック内における少なくとも1つ以上の画素の画素値を補正する補正量を算出し、この補正量を用いて共有ブロック内における少なくとも1つ以上の画素の画素値を補正する欠陥ブロック補正部23と、を備える。
