There is provided a focus control apparatus including: an information acquisition unit that acquires focal distance information of a predetermined position on a 2-dimensional map using the 2-dimensional map of focal distances; and a focus control unit that performs focus control based on the focal distance information which is acquired by the information acquisition unit.

There is provided a focus adjustment apparatus. A first obtainment unit obtains a focus degree in a predetermined region of a shooting range. A driving unit drives a focus lens in response to an operation unit being operated. A movement amount of the focus lens per unit of an operation amount of the operation unit during the driving is lower in a case where the focus degree is greater than a focus threshold than in a case where the focus degree is lower than the focus threshold. The focus threshold is higher in a case where the focus lens is moving in a direction that increases the focus degree than in a case where the focus lens is moving in a direction that reduces the focus degree.

An apparatus includes an acquisition unit configured to acquire a first captured image obtained by first image capturing with a first image capturing parameter and motion information about an object in the first captured image, a setting unit configured to set a second image capturing parameter, an estimation unit configured to estimate motion blur of an object in a second captured image which is obtained in a case where second image capturing is performed with the second image capturing parameter, based on the motion information and the second image capturing parameter, and a notification unit configured to issue a notification of the motion blur.

The present disclosure relates to a portable scanner capable of increasing the precision of focus and a scanning method using the same. According to an embodiment of the present disclosure, the portable scanner, which generates a three dimensional (3D) image from a subject, includes a focus state output device to determine a present focus state with respect to a set focal length from a subject and to output the present focus state such that a user recognizes the present focus state.
