Image processing apparatus and image processing method

摘要

An image processing apparatus configured to detect a position deviation between a first image and a second image includes a first memory configured to store motion vectors between the first image and the second image as a first motion vector group, a second memory configured to store, as a second motion vector group, motion vectors extracted from the first motion vector group determined to have a higher reliability than a predetermined threshold, an acceptable motion vector selection unit configured to calculate a temporary position deviation parameter from the second motion vector group, and select the motion vectors representing the position deviation as an acceptable motion vector group from the first motion vector group, using the temporary position deviation parameter, and a parameter estimation unit configured to estimate the position deviation parameter representing the position deviation from the acceptable motion vector group.

1. An image processing apparatus configured to detect a position deviation between a first image and a second image, the image processing apparatus comprising:
a detection unit configured to detect a plurality of motion vectors between the first image and the second image for each area; a first memory configured to store respective pieces of information about the plurality of motion vectors as a first motion vector group; a reliability calculation unit configured to calculate a reliability with respect to the detection of the position deviation for each of the pieces of information about the motion vectors to be read out of the first memory; an extraction unit configured to extract the information about the motion vector of which reliability has been determined to be higher than a predetermined threshold value; a second memory configured to store the extracted information about the motion vector as a second motion vector group; a selection unit configured to calculate a temporary position deviation parameter from the second motion vector group to be read out of the second memory, and to select the motion vector representing a position deviation corresponding to a position deviation represented by the temporary position deviation parameter as an acceptable motion vector group from the first motion vector group; and a parameter estimation unit configured to estimate the position deviation parameter representing the position deviation from the acceptable motion vector group.
