The present invention expands the dynamic range of an image and improves the sn ratio to improve the image quality. An image processing apparatus according to the present disclosure includes a light amount determination unit that determines a light amount of the captured image based on a pixel value of each pixel of the captured image based on a pixel value of each pixel of the captured image. An exposure ratio determining unit that determines a ratio of an exposure amount of a long-time exposure pixel to an exposure amount of a short-time exposure pixel based on a ratio of pixels in which the pixel value is saturated among pixels included in the captured image region And comprising. [Selection] Figure 2【課題】画像のダイナミックレンジを拡大するとともに、ｓｎ比を向上して画質を良好にする。【解決手段】本開示に係る画像処理装置は、撮像画像の各画素の画素値に基づいて、撮像画像の各画素の画素値に基づいて、前記撮像画像の光量を決定する光量決定部と、前記撮像画像の領域に含まれる画素のうち前記画素値が飽和している画素の比率に基づいて、短時間露光画素の露光量に対する長時間露光画素の露光量の比を決定する露光比決定部と、を備える。【選択図】図２
