Abstract: An evaluation method of an image stabilization effect of an imaging device includes calculating an evaluation value of the image stabilization effect on the basis of shutter speed values in case of which each of a reference shake amount theoretically calculated on the basis of a shake waveform applied to the imaging device and a measured shake amount calculated using an image captured in a state in which the imaging device is vibrated becomes a specified shake amount, and setting the specified shake amount. The setting includes calculating an image deterioration amount of the imaging device caused by something other than a shake from the outside, and selecting a determination level that defines the specified shake amount from a plurality of determination levels having different shake amounts on the basis of the image deterioration amount.

Abstract: A handheld blur evaluating apparatus is configured to evaluate a handheld blur of an imaging unit. The handheld blur evaluating apparatus includes an excitation unit configured to excite the imaging unit configured to image an object, a detector configured to detect disturbance in a change amount in measurement data of an image imaged by changing an imaging condition relating to exposure time or luminance, and a driving state indicating that the excitation unit is in a stationary state or in an excitation state, and a corrector configured to correct the disturbance.

Abstract: An evaluating apparatus is configured to evaluate image stabilizing performance of an imaging unit around an optical axis. The evaluating apparatus includes an object disposed to face the imaging unit, the object having a first feature point at a position different from the optical axis of the imaging unit, an excitation unit configured to excite the imaging unit, and an evaluating unit configured to evaluate an image of the object captured by the imaging unit that is being excited by the excitation unit.

Abstract: An image evaluation apparatus comprises an image capturing device configured to include a blur correction function, a vibration control unit configured to vibrate the image capturing device based on an input waveform, a vibration detection unit that detects the vibration of the image capturing unit, a memory storing instructions, and a processor executing the instructions causing the image evaluation apparatus to compare the input waveform with the waveform of the vibration detection result that was detected by the vibration detection unit, and perform a captured image evaluation that is an evaluation of the blur correction function based on a captured image result of a subject by the image capturing device, wherein the processor performs captured image evaluation in a case in which it has been determined that the difference of the waveform of the vibration detection result with respect to the input waveform is within a predetermined range.

Abstract: The present invention provides an evaluation method for more precisely determining the blur correction capability of an image capturing apparatus. The method for evaluating the blur correction effect of the image capturing apparatus comprises acquiring a first change amount for each image capture from a predetermined captured number of subject images that have been captured by an image capturing apparatus that has been vibrated; dividing the predetermined number of captured images into a plurality of segments, and calculating a second change amount for each segment by performing statistical processing on the first change amounts in each of the plurality of segments; determining the largest second change amount from among the second change amounts in each segment to serve as a third change amount; and performing evaluation of the blur correction effect based on the third change amount.
