The present invention addresses the problem of providing an image processing device, growth examination image creation system, and program that make it possible to correct the brightness of each of the pixels in an aerial image and accurately analyze the state of growth of plants. The present invention is provided with: an inputting means (communication I/F 24) for inputting an aerial image of plants in a field, captured by using an aerial image acquisition device 1A; a correction value calculating means (control unit 21) for using imaging information on when the aerial image was captured to calculate a correction value for a luminance value of each of the pixels in the aerial image; and a correcting means (control unit 21) for using the correction value to correct the luminance value of each of the pixels in the aerial image. The imaging information comprises imaging location information and solar position information. The imaging location information includes information on the latitude and longitude at whi
