Image processing device, imaging system provided therewith, and calibration method

An image processing device that outputs a composite image by performing an image composition process on an image for each of a plurality of cameras, the image processing device comprising:

• a processor;
• and
• a memory including instructions that, when executed by the processor, cause the processor to perform operations, the operations including:
• generating a plurality of composition source images from the image for each of the plurality of cameras based on a preset processing condition;
• performing the image composition process on the plurality of composition source images to generate a composite image for preview, the composite image including a plurality of camera image regions, each of the plurality of camera image regions corresponding to one of the plurality of composition source images and one of the plurality of cameras;
• generating a preview display screen on which the composite image is displayed and outputting the preview display screen to a display;
• detecting a first touch operation that a user performs on the preview display screen displayed on the display and determining a first adjustment item according to the first touch operation, the first touch operation being performed with one or two fingers and in relation to a first camera image region of the plurality of camera image regions, the first camera image region corresponding to a first composition source image of the plurality of composition source images and a first camera of the plurality of cameras;
• first adjusting at least one of the first composition source image or the first camera according to the first adjustment item and updating the composite image;
• detecting a second touch operation that the user performs on the preview display screen displayed on the display and determining a second adjustment item, the second touch operation being performed with at least three fingers;
• and
• second adjusting at least one of all composition source images of the plurality of composition source images or all cameras of the plurality of cameras according to the second adjustment item and updating the composite image.
