Blur correction device and blur correction method

An integrated circuit that electronically corrects blur occurring in an image captured using a camera to generate a corrected image from the captured image, said integrated circuit comprising:

• a blur information generation unit configured to generate blur information for correcting the blur occurring in the captured image, based on sensor data indicating motion of the camera, the sensor data being detected using a motion detection sensor during the image-capturing of the captured image;
• a blur correction unit configured to correct the blur occurring in the captured image, based on the blur information generated by said blur information generation unit, to generate a candidate corrected image;
• an evaluation value calculation unit configured to calculate an evaluation value which is an evaluation value for the candidate corrected image generated by said blur correction unit and indicates a blur correction level;
• a termination judgment unit configured to judge whether or not the blur correction should be terminated, based on a predetermined condition;
• and
• a blur information updating unit configured to update the blur information generated by said blur information generation unit, when said termination judgment unit judges that the blur correction should not be terminated,
• wherein, when the blur information is updated by said blur information updating unit, said blur correction unit is configured to correct the blur occurring in the captured image, based on the updated blur information, to generate a new candidate corrected image, and
• upon judging that the blur correction should be terminated, said termination judgment unit is configured to determine the corrected image from the at least one candidate corrected images generated by said blur correction unit, based on the evaluation value calculated by said evaluation value calculation unit.

A blur correction method of electronically correcting blur occurring in an image captured using a camera to generate a corrected image from the captured image, said blur correction method comprising:

• generating blur information for correcting the blur occurring in the captured image, based on sensor data indicating motion of the camera, the sensor data being detected using a motion detection sensor during the image-capturing of the captured image;
• correcting the blur occurring in the captured image, based on the blur information generated in said generating, to generate a candidate corrected image;
• calculating an evaluation value which is an evaluation value for the candidate corrected image generated in said correcting and indicates a blur correction level;
• judging whether or not the blur correction should be terminated, based on a predetermined condition;
• and
• updating the blur information generated in said generating, when it is judged in said judging that the blur correction should not be terminated,
• wherein in said correcting, when the blur information is updated in said updating, the blur occurring in the captured image is corrected based on the updated blur information to generate a new candidate corrected image, and
• in said judging, when it is judged that the blur correction should be terminated, the corrected image is determined from the at least one candidate corrected images generated in said correcting, based on the evaluation value calculated in said calculating.
