Claim One:
1. An image processing apparatus that generates a mosaic image in which a plurality of images are connected, the mosaic image including a reference image and a correction image to be corrected, the apparatus comprising an image processing unit that corrects a pixel value of the correction image based on the reference image, wherein the image processing unit determines a tone curve that defines an output pixel value with respect to an input pixel value, and converts the pixel value of the correction image using the tone curve, the tone curve being generated so as to pass through a pixel-value-conversion coordinate point that is defined by a correction-image pixel value and a reference-image pixel value set as input and output values, the correction-image pixel value constituting a pixel-value-adjustment representative point that is selected from the correction image, the reference-image pixel value constituting a pixel-value-adjustment representative point that is selected from the reference image, the pixel-value-adjustment representative points selected from the correction image and the reference image being points at which the same pixel value is to be set, and the pixel value of the correction image is converted based on the generated tone curve.
