Zusammenfassung:To reduce the load required for image processing of image data.SOLUTION: An image processing device includes a separation processing unit that separates first image data acquired by an image sensor with Bayer layout into second image data containing luminance information and third image data containing color information and having a smaller resolution than the first and second image data. The pixel array of the third image data is an array in which two pixels are the same type at one diagonal position and two pixels are different types at the other diagonal position for each area containing two pixels in each of the horizontal and vertical directions. The two pixels at the other diagonal position are different types from the two pixels at the one diagonal position.SELECTED DRAWING: Figure 7 【課題】画像データの画像処理に掛かる負荷を低減する。【解決手段】画像処理装置は、ベイヤー配列のイメージセンサにより取得された第1画像データを、輝度情報を含む第2画像データと、色情報を含み、前記第1画像データおよび前記第2画像データよりも解像度が小さい第3画像データとに分離する分離処理部を有し、前記第3画像データの画素配列は、水平方向と垂直方向とのそれぞれに2画素を含む領域毎に、一方の対角の2画素が同種で、他方の対角の2画素が異種の配列であり、前記他方の対角の2画素は、前記一方の対角の2画素と異種である。【選択図】図7
