Title: IMAGE PROCESSING DEVICE, IMAGE PICKUP APPARATUS, AND IMAGE PROCESSING PROGRAM
Abstract:
This image processing device is characterized by being provided with: a graph generation means which generates a three-dimensional graph in which pixels included in a plurality of frame images that constitute a moving image are respectively disposed as nodes in a three-dimensional space composed of a spatial direction and a temporal direction, and difference values between two pixels adjacent in the spatial direction and/or the temporal direction are set as weights between adjacent nodes; a minimum spanning tree generation means which finds a minimum spanning tree in the three-dimensional graph by, using a weight between nodes that is the minimum among the weights between nodes adjacent in the spatial direction and/or the temporal direction in the three-dimensional graph and an evaluation parameter, repeatedly executing processing for evaluating whether or not to connect the nodes between which the weight is the minimum; and a parameter setting means which has a first parameter set for the spatial direction and a second parameter having a value different from that of the first parameter and set for the temporal direction, and sets either the first parameter or the second parameter as the evaluation parameter.
