An image processing system including a display provided in a cabin of a vehicle, ahead of a driver of the vehicle, and an image processing device for generating a display image to be displayed on a display area of the display, the image processing device comprising: an information acquisition unit configured to acquire, from a captured image that is captured by an imaging device and in which a forward view from the vehicle is captured, color information of the forward view from the vehicle; an image generation unit configured to generate a first image and a second image, different from the first image; and an output unit configured to output the first and second images (24, 25) to the display, the first image being displayed in a first area of the display area and the second image being displayed in a second area of the display area, different from the first area; characterized in that: the display is provided in a place in which a part of the display area obstructs from view a part of the windshield of the vehicle and the other part obstructs an interior portion of the vehicle, the first area being on the windshield part and the second area being on the interior-portion part; the first area is included in a visual field of the driver of the vehicle when the driver visually recognizes the forward view through the windshield; the image generation unit is configured to extract the image of a target range corresponding to the first area from the captured image and to perform a blurring process on the extracted image based on the color information of the forward view so as to generate the first image, wherein the level of the blurring process is set such that the difference in color information between the forward view and the first image is within a predetermined range; the first image serves as a first background image in the display image; the second image serves as a second background image in the display image; the image generation unit is configured to superpose content information (71, 72) on the first image and second image to generate the display image, the content information being information to be provided to the driver of the vehicle; and the output unit is configured to output the display image to the display. an information acquisition unit configured to acquire, from a captured image that is captured by an imaging device and in which a forward view from the vehicle is captured, color information of the forward view from the vehicle;
