1. An image-taking apparatus comprising:

  • an image pickup device which generates an image signal upon receipt of irradiation of a shooting object image;

    an image-taking optical system which includes an optical member for focus adjustment and focuses the shooting object image on the image pickup device;

    a shooting section which causes the image pickup device to generate a recording image signal and records the recording image signal in response to a shooting operation;

    a focus adjusting section which performs focus adjustment by driving the optical member such that a ranging area defined within a shooting field angle constitutes a focused position;

    a sensor, which detects a shake of the image-taking apparatus in a horizontal direction of the image-taking apparatus which indicates a switch between shooting conditions and a shake of the image-taking apparatus in a vertical direction of the image-taking apparatus which indicates a switch between modes of a selected shooting condition selected from a flash mode, a focus mode, a white balance (WB) mode, an International Organization for Standardization (ISO) sensitivity mode, an auto focus (AF) mode, one-point mode, and an automatic exposure (AE) mode;

    controlling means for determining whether the detected shake is an intentional shake or an unintentional shake;

    a shake correcting section which performs a shake correction processing and corrects the determined unintentional shake, and wherein the one point mode selected and the focus adjusting section switches the ranging area to another defined ranging area within the shooting field angle in response to the determined intentional shake, the another defined ranging area being positioned in a direction of the determined intentional shake in terms of the ranging area, and the focus adjusting section does determined intentional shake in terms of the ranging area not switch the ranging area in response to the determined unintentional shake andwherein the controlling means determines that the detected shake is the unintentional shake if a degree of the shake is between a first predetermined threshold and a second predetermined threshold, which is greater than the first predetermined threshold, and determines that the detected shake is the intentional shake if the degree of the shake exceeds the second predetermined threshold.
