PROBLEM TO BE SOLVED: To make it possible to evaluate a skin surface condition by a lower cost configuration.SOLUTION: An imaging apparatus comprises: a non-polarization light emitting part that emits non-polarization component light; a polarization light emitting part that emits specific polarization component light via a first polarization filter; and an imager that images, via a second polarization filter, a subject illuminated by the non-polarization light emitting part or polarization emitting part. The polarization direction of the first polarization filter and that of the second polarization filter are orthogonal to each other. The imager images a subject illuminated by the non-polarization light emitting part and a subject illuminated by the polarization light emitting part in a time division manner, and outputs a non-polarization image and an orthogonal polarization image that are acquired as a result of time division imaging. The technique according to disclosure can be applied in an imager or the like, used to evaluate, for example, a skin surface condition. 【課題】より低コストな構成で肌の表面状態を評価することができるようにする。【解決手段】撮像装置は、無偏光成分の光を照射する無偏光発光部と、第１の偏光フィルタを介して所定の偏光成分の光を照射する偏光発光部と、無偏光発光部または偏光発光部により照射された被写体を第２の偏光フィルタを介して撮像する撮像素子とを備え、第１の偏光フィルタと第２の偏光フィルタの偏光方向は直交関係にある。撮像素子は、無偏光発光部により照射された被写体と、偏光発光部により照射された被写体を時分割で撮像し、その結果得られる無偏光画像と直交偏光画像を出力するように構成されている。本開示の技術は、例えば、肌の表面状態を評価する撮像装置等に適用できる。【選択図】図２
