Abstract: Provided is a video recording apparatus that can generate image signals to increase a difference in amount of blur in recording video using a rolling shutter during wobbling, and includes: an image sensor that generates an image signal corresponding to an image; a driving unit that drives a focus lens along an optical axis; and a control unit that controls the driving unit for controlling a focus in an optical system, while the focus lens is wobbling, wherein the control unit (i) generates blur signals to increase a difference in amount of blur in a predetermined region by controlling imaging timings at which the image sensor captures the image, (ii) calculates distance information on a distance to the object to be displayed in the region, using blur signals in the region among the generated blur signals, and (iii) controls the focus using the distance information.
