BLUR DETECTOR, BLUR CORRECTION CAMERA AND RECORDING MEDIUM RECORDING BLUR DETECTION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a blur detector, a blur correction camera and a recording medium recording a blur detection program precisely estimating a blur waveform. SOLUTION: An attractor generation part 410 extracts time sequential information from a blur detection signal outputted by an angular velocity sensor, and generates an attractor track by burying this time sequential information in multi-dimensional space. A vector generation part 460 generates time sequentially plural vectors connecting track points on this attractor track with past track points on the attractor track. A mapping operation part 470 operates time sequentially plural mapping among these vectors, and an inter-mapping fluctuation operation part 480 outputs inter-mapping fluctuational information by operating fluctuation of inter-mapping. A track estimative operation part 490 generates time sequentially the newest mapping based on this inter-mapping fluctuational information, and estimates a future track point based on this mapping.
