摘要： A frame is divided into blocks each having a predetermined size, and motion vectors are calculated for respective blocks. The blocks are classified into an object group including an object image and a background group as a background image based on the calculated motion vectors, and representative motion vectors of the respective groups are calculated. The number of blocks included in the object group is compared with a threshold. When the number of blocks is larger than the threshold, the representative motion vector of the object group is selected as a motion vector for the entire frame. On the other hand, when the number of blocks included in the object group is smaller than the threshold, the representative motion vector of the background group is selected as the motion vector for the entire frame.

摘要： PROBLEM TO BE SOLVED: To provide a device for detecting a motion vector capable of reliably correcting camera shake while removing a panning component. SOLUTION: The device for detecting a motion vector includes: a detection unit 106 for dividing an image into a plurality of block areas to detect a motion vector for every divided block area; a panning decision unit 30 for executing panning decision for every block area; a motion vector classification unit 31 for distributing the motion vectors other than those in the block area determined to be in a panning state on a frequency distribution using the values thereof as classes; and a motion vector calculation unit 32 for defining a representative motion vector based on the value of the frequency. The motion vector classification unit 31 can remove the block area determined to be in the panning state by the panning decision unit 30 from the distribution objects onto the frequency distribution, and thereby prevent hindering of the panning operation of a user in panning imaging.

摘要： PROBLEM TO BE SOLVED: To identify a motion vector generated by shaking of an imaging apparatus from a motion vector generated by movement of a moving object with high precision. SOLUTION: A motion vector detecting apparatus includes: a detecting part 106 which divides image data into a plurality of block areas and detects a motion vector for each of the divided block areas; a motion vector classifying part 30 which distributes the motion vectors for respective block areas to a frequency distribution taking their sizes as grades and classifies the motion vectors for the respective block areas into one or more groups based on the magnitude of frequency and interval between grades; and a selecting part 31 which selects one group from among the plurality of classified groups and determines one representative motion vector. Based on magnitude relations of grade values which become a representative of a plurality of groups in the past image data and those in the present image data, the selecting part selects one group from among the plurality of groups in the present image data.

摘要： A direction instructing operation unit instructs a control unit to change a direction of a change in the photographic screen range. First motor drives a compensation optical system and second motor drives a compensation optical system in accordance with the control command given by the control unit. When the direction along which framing adjustment has been instructed by the direction instructing operation unit matches neither the drive direction of the first motor nor the drive direction of the second motor for driving the compensation optical system, the control unit matches a drive start time and a drive end time of both the first motor and the second motor, and then controls the ratio of the speed of the second drive unit to the speed of the first drive unit at a constant level to thereby control the moving direction of the photographic screen range.
