PROBLEM TO BE SOLVED: To provide a technology such as an imaging apparatus capable of effectively correcting a flicker between frames.SOLUTION: The imaging apparatus includes a permeability adjusting section, an imaging device and a control section. The permeability adjusting section is capable of adjusting a permeability of light in accordance with an application voltage. The imaging device performs imaging by exposing the light that permeates through the permeability adjusting section. The control section makes the imaging device perform imaging to acquire a plurality of image data items, determines a cycle of the flicker between the plurality of image data items on the basis of the plurality of image data items, calculates a permeability for correcting the flicker between the plurality of image data items on the basis of the cycle of the flicker, sets the permeability of the permeability adjusting section to the calculated permeability, makes the imaging section perform imaging. 【課題】フレーム間フリッカを効果的に補正することができる撮像装置などの技術を提供すること。【解決手段】本技術に係る撮像装置は、透過率調整部と、撮像素子と、制御部とを具備する。前記透過率調整部は、印加電圧に応じて光の透過率を調整可能とされている。前記撮像素子は、透過率調整部を透過した光を露光することにより撮像を行う。前記制御部は、前記撮像素子に撮像を行わせて複数の画像データを取得し、前記複数の画像データに基づいて、前記複数の画像データ間におけるフリッカの周期を判定し、前記フリッカの周期に基づいて、複数の画像データ間におけるフリッカを補正するための透過率を算出し、算出された透過率に前記透過率調整部の透過率を設定して前記撮像部により撮像を行わせる。【選択図】図３
