Camera shake blur in the Image Sensor Inconsistent light
Camera Shake Three (3) Degrees of Freedom: Rotational shake Lateral Shake Longitudinal Shake
Image Frame As camera shakes/rotates, the image frame that it covers (“field of view”) shifts Capturing inconsistent image yields blur
Image Frame If the camera shakes less, the image changes less More consistent image yields less blur
Wider angle of view means same physical rotation/shake alters field of view less This more consistent image yields less blur
Large shake Narrow angle Small shake Narrow angle Large shake Wide angle
How much blur? Displacement amount Φ = angle of rotation (shake) θ = angle of view 1 frame length Displacement amount 1 frame length
How much blur? Displacement amount Δx = camera displacement r = subject distance 1 frame length θ = angle of view Displacement amount 1 frame length
