PROBLEM TO BE SOLVED: To efficiently generate a locus-synthesized image of moving objects from a plurality of images taken in time series without being affected by the condition of the background in the taken image, and the number, the size, the deformation, the color, etc. of the moving objects. SOLUTION: An image processing apparatus includes a locus pixel selection unit 121, a background pixel selection unit 122, a background generation unit 130, a degree-of-difference generation unit 140, and a locus synthesis unit 150. The locus pixel selection unit 121 selects n pieces of pixel values in corresponding pixel positions as for n frames of input image 110 being imaged in time series. The background pixel selection unit 122 selects a pixel value necessary for the generation of a background value among n pieces of pixel values in corresponding pixel positions as for n frames of the input image 110 being imaged in time series. The background generation unit 130 generates a background value based on the pixel value supplied from the background pixel selection unit 122. The degree-of-difference generation unit 140 generates a degree of difference between the background value supplied from the background generation unit 130 and the pixel value supplied from the locus pixel selection unit 122. The locus synthesis unit 150 synthesizes a pixel value supplied from the locus pixel selection unit 122, based on the degree of difference supplied by the degree-of-difference generation unit 140.
