PROBLEM TO BE SOLVED: To highly accurately generate a high resolution image, while reducing the load of image processing.SOLUTION: A polarization control unit used for an imaging apparatus includes a first polarizer 102, a polarization control element 103 which adjusts the polarization direction of light after passing through the first polarizer, and a second polarizer 104 which allows the light through the polarization control element to pass through. At least one of the first and second polarizers includes a plurality of areas. In at least two of the plurality of areas, the polarization directions of the light allowed to pass through are different from each other and the light allowed to pass through is made incident on the same pixel in the imaging element of the imaging apparatus.SELECTED DRAWING: Figure 1【課題】画像処理の負担を低減しつつ高精度に高解像度画像を生成すること【解決手段】撮像装置に使用される偏光制御ユニットは、第１の偏光子１０２と、第１の偏光子を通過した光の偏光方向を調節する偏光制御素子１０３と、偏光制御素子を介した光を通過させる第２の偏光子１０４と、を有する。第１および第２の偏光子の少なくとも一方は複数の領域を含み、該複数の領域の少なくとも２つは、通過させる光の偏光方向が互いに異なり、前記通過させる光は、前記撮像装置の撮像素子における同一の画素に入射する。【選択図】図１
