[0024] An embodiment will now be described in which the imaging apparatus according to the present invention is applied to, for example, a digital video camera (hereinafter referred to as "camera") for capturing moving images.

[0025]

[0026] will refer to figure 1 and figure 2 The structure of the video camera 100 according to this embodiment is described.

[0027] refer to figure 1 , the optical system 101 is composed of a zoom lens group, a stop, an ND (neutral density) filter, and the like. Reference numeral 102 denotes a focusing lens. The imaging unit 103 includes an image sensor such as a CCD or CMOS, and is composed of a sample and hold circuit (S / H circuit), a preprocessing circuit, and the like. Reference numeral 104 denotes a signal processing unit; reference numeral 106 denotes a signal recording unit; and reference numeral 107 denotes a recording medium such as a flash memory. The control unit 108 controls the entire camera. The operating member 109 is ...

no. 2 example

[0072] Next, a second embodiment will be described. The video camera according to this embodiment has the same structure as the first embodiment except for user operation for focus movement control and focus lens position control in response to user operation, and description thereof will be omitted.

[0073] Two types of operation examples will be described focusing on differences from the first embodiment.

[0074]

[0075] will refer to Figure 7A to Figure 7D A first operation example of focus movement control by the video camera 100 according to this embodiment is described. In the first operation example, as in the first embodiment, the user performs an operation to gradually move the focus area to a new focus object.

[0076] refer to Figure 7A ,and Figure 3A Also, a scene with two people (a man and a woman among flowers) is displayed as a subject of shooting. Frame 701 indicates that the control unit 108 has selected the area of ​​the flower bushes on the near...

Abstract

An image capturing apparatus and a control method thereof are provided. The image capturing apparatus comprises an image capturing unit configured to capture an image of an object via an optical system, a display unit configured to display the image captured by the image capturing unit on a screen, a detection unit configured to simultaneously detect a plurality of touch positions on the screen on which the image is displayed, and a control unit configured to adjust a focus state in accordance with a change in a distance between a first detected touch position and a second detected touch position, so as to change a focus area.

Description

technical field [0001] The present invention relates to an imaging device and a control method thereof, in particular to a focus movement control technology for arbitrarily moving a focus object according to user operations on the imaging device. Background technique [0002] Recently, some imaging apparatuses such as digital video cameras and digital still cameras have a function of automatically focusing on a subject when a user touches an arbitrary subject on a display screen displaying the subject (for example, Japanese Patent Laid-Open 2011-039457 Bulletin). [0003] In addition to the function of focusing on a desired subject, the user wants to make the captured video appear as an intentionally out-of-focus image. In addition, as in Japanese Patent Laid-Open No. 2011-039457, when specifying a focus area by touching a display screen including an operation device such as a touch panel, the user may temporarily hide the object subject portion with a finger or the like, a...
