Image correction parameter output apparatus, camera system and correction parameter output method

A camera system, comprising:

• a plurality of cameras configured to generate a plurality of images of an area surrounding the moving object captured with partially overlapped with each other;
• a memory configured to store groups of correction parameters to be used to correct the plurality of images by associating the groups with control information of the moving object;
• a controller configured to execute functions of:
• an acquisition unit configured to acquire the control information of the moving object;
• and
• an output unit configured to output a group of correction parameters corresponding to the acquired control information;
• and
• a camera controller configured to execute functions of:
• an image processor configured to correct the plurality of images based on a correction parameter outputted by the output unit;
• and
• an image combining unit configured to combine the plurality of corrected images to generate a combined image, wherein
• each of the groups of correction parameters includes at least one of a set of color correction parameters respectively defined for the plurality of images and a set of luminance correction parameters respectively defined for the plurality of images;
• and
• the set of color correction parameters and the set of luminance correction parameters are predetermined without using image data of the plurality of images.

An image correction parameter output method comprising the steps of:

• storing groups of correction parameters to be used to correct a plurality of images of an area surrounding a moving object captured with partially overlapped with each other by associating the groups with control information of the moving object;
• acquiring the control information of the moving object;
• and
• outputting a group of correction parameters corresponding to the acquired control information, wherein
• each of the groups of correction parameters includes at least one of a set of color correction parameters respectively defined for the plurality of images and a set of luminance correction parameters respectively defined for the plurality of images;
• and
• the set of color correction parameters and the set of luminance correction parameters are predetermined without using image data of the plurality of images.
