Abstract:
An image blur prevention apparatus adapted to a camera having an exposure portion, comprising:a first image blur detecting device that detects an image blur state of the camera; a second image blur detecting device that detects an image blur state of an optical image of the camera, and outputs a detection signal; a determining portion that determines a photographing operation state of the camera; a calculating device having a first calculation program and a second calculation program, wherein said calculating device selects one calculation program from among the first and second calculating programs based on a determination result of said determining portion, and wherein said calculating device calculates a predicted blur signal, in accordance with the selected calculation program, based on the detection signal of said second image blur detection device; and an image blur prevention device that performs an image blur prevention operation, based on the detection signal of said first image blur detecting device and the predicted blur signal calculated by said calculating device, during a light exposing operation onto the exposure portion of the camera.
