Publication number: 20240135499Abstract: An image processing apparatus includes circuitry to input at least a first captured image and a second captured image. The first captured image and the second captured image have an overlapping area. The overlapping area in the first captured image has a plurality of target areas in each of which a stitching position is to be obtained. The plurality of target areas is arranged in an orthogonal direction with respect to a direction in which the first captured image and the second captured image are arranged and have a corresponding plurality of sizes different from each other.Type: ApplicationFiled: October 10, 2023Publication date: April 25, 2024Inventor: Kenichiroh NOMURA
