To perform distance measurement with high accuracy.SOLUTION: An image processing device includes: a long-exposure distance image generator that calculates parallax from a first long-exposure image and a second long-exposure image obtained from a first long-exposure camera and a second long-exposure camera that capture images with long-exposure and are arranged at a predetermined interval, and generates a long-exposure distance image; a short-exposure distance image generator that calculates parallax from a first short-exposure image and a second short-exposure image obtained from a first short-exposure camera and a second short-exposure camera that capture images with short-exposure and are arranged at a predetermined interval, and generates a short-exposure distance image; and a distance image generator that generates a distance image by synthesizing the long-exposure distance image and the short-exposure distance image. This technique can be applied to the image processing device that measures a distance to an object by analyzing the images.SELECTED DRAWING: Figure 1 【課題】距離測定を精度良く行う。【解決手段】長時間露光で画像を撮像し、所定の間隔を有して配置されている第１の長時間露光カメラと第２の長時間露光カメラからの第１の長時間露光画像と第２の長時間露光画像とから視差を算出し、長時間露光距離画像を生成する長時間露光距離画像生成部と、短時間露光で画像を撮像し、所定の間隔を有して配置されている第１の短時間露光カメラと第２の短時間露光カメラからの第１の短時間露光画像と第２の短時間露光画像とから視差を算出し、短時間露光距離画像を生成する短時間露光距離画像生成部と、長時間露光距離画像と短時間露光距離画像を合成して距離画像を生成する距離画像生成部とを備える。本技術は、画像を解析することで対象物までの距離を測定する画像処理装置に適用できる。【選択図】図１
