Abstract:
1. An image pickup apparatus comprising: a main body unit including an imaging unit configured to take a dynamic picture image and a memory unit configured to temporarily store the dynamic picture image taken by the imaging unit; an image-blur-amount calculation unit configured to calculate an image blur amount of the dynamic picture image, based on a blur of the main body unit in taking the dynamic picture image; an optical correction unit configured to optically correct an image blur of the dynamic picture image by correcting an incident light on the imaging unit; an electronic correction unit configured to electronically correct the image blur of the dynamic picture image by cutting out an image having a designated area from the dynamic picture image temporarily memo unit; a shutter-speed calculation unit configured to calculate a shutter speed of the imaging unit; and an image-blur-correction control unit configured to execute control of calculating an optical correction amount by the optical correction unit and allowing the optical correction unit to optically correct the image blur based on the optical correction amount, and also calculating an electronic correction amount by the electronic correction unit and allowing the electronic correction unit to electronically correct the image blur based on the electronic correction amount, based on at least one of the amount of image blur and the shutter speed both calculated, wherein the image-blur-correction control unit sets the optical correction amount to zero when the shutter speed calculated by the shutter-speed calculation unit is equal to or more than a first threshold value, and wherein the image-blur-correction control unit is configured to calculate the electronic correction amount so that a maximum correction amount of the electronic correction amount is increased more gradually as the shutter speed calculated gets more quickly when the shutter speed calculated by the shutter-speed calculation unit is equal to or more than a second threshold value smaller than the first threshold value and is less than the first threshold value.
