Imaging device configured to control a region of imaging

Abstract

An imaging device to control a region of imaging, includes: an imaging unit; a display unit; and a control unit. The control unit is configured to: set a first region of a predetermined size at a predetermined position in an imaging range of the imaging unit; make the display unit display an image in the first region as live-view image; fix a position of the first region in the imaging range before a first operation is performed; after the first operation is performed, displace the position of the first region in the imaging range so as to track movement of a specific subject in the imaging range; and when a second operation is performed, following the first operation, record a partial image corresponding to the first region in an entire image taken by the imaging unit.

         2 . The imaging device according to  claim 1 , wherein
 the control unit is configured to:   make the display unit successively display an entire image that is successively taken by the imaging unit as the live-view image;   during displaying the entire image as the live-view image, set the first region; and   make the display unit display the first region recognizably in the entire image as the live-view image.   
     
     
         3 . The imaging device according to  claim 2 , wherein
 the control unit is configured to:   before the first operation is performed, allow at least one of a size and a shape of the first region to be changed while fixing the position of the first region relative to the imaging range, and   when the first operation is performed, displace the position of the first region while fixing the size and the shape of the first region.   
     
     
         4 . The imaging device according to  claim 1 , wherein
 the control unit is configured to:   cut the first region from an entire image taken by the imaging unit; and   when the second operation is performed, associate a partial image corresponding to the cut first region and the entire image taken by the imaging unit for recording.   
     
     
         5 . The imaging device according to  claim 2 , wherein
 the control unit is configured to, when the first operation is performed, switch the live-view image successively displayed on the display unit from an entire image successively taken by the imaging unit to a partial image corresponding to the first region, the partial image being successively cut.   
     
     
         6 . The imaging device according to  claim 5 , wherein
 the control unit is configured to:   display, at a predetermined position of the partial image corresponding to the first region that is successively displayed on the display unit as the live-view image, an entire image taken by the imaging unit, the entire image being reduced in size and being successively synthesized; and   display a frame in the entire image that is displayed at the predetermined position of the partial image while being reduced in size and being synthesized, the frame indicating a position and a size of the first region.   
     
     
         7 . The imaging device according to  claim 5 , wherein
 the control unit is configured to display a frame indicating the first region in an entire image that is successively displayed on the display unit as the live-view image.   
     
     
         8 . The imaging device according to  claim 7 , wherein
 the control unit is configured to, before the first operation is performed, display an image at a region other than the first region in an entire image that is successively displayed on the display unit as the live-view image so that the image at the region other than the first region is displayed in a predetermined display mode so as to be relatively less prominent than a partial image corresponding to the first region.   
     
     
         9 . The imaging device according to  claim 8 , wherein
 the control unit is configured to, when the first operation is performed, display a frame indicating the first region having a fixed size and shape in an entire image as the live-view image, and cancel displaying of the image at the region other than the first region in the predetermined display mode.   
     
     
         10 . The imaging device according to  claim 8 , wherein
 the control unit is configured to:   specify a plurality of combinations of a size and a shape of the first region so that at least one of the size and the shape is changed; and   in response to a third operation performed before the first operation, select any one of the plurality of combinations specified and display the first region of a size and a shape corresponding to the selected combination recognizably in an entire image as the live-view image.   
     
     
         11 . The imaging device according to  claim 1 , wherein
 the control unit is configured to:   detect movement of the specific subject in the first region relative to an imaging range of the imaging unit; and   displace a position of the first region in the imaging range in accordance with the detected relative movement of the specific subject.   
     
     
         12 . An imaging method by an imaging device, comprising:
 setting a first region of a predetermined size at a predetermined position in an imaging range of an imaging unit;   making a display unit an image in the set first region as live-view image;   fixing a position of the first region in the imaging range before a first operation is performed;   after the first operation is performed, displacing the position of the first region in the imaging range so as to track movement of a specific subject in the imaging range; and   when a second operation is performed, following the first operation, recording a partial image corresponding to the first region in an entire image taken by the imaging unit.   
     
     
         13 . A non-transitory recording medium including a program recorded therein, the program making a computer of an imaging unit:
 set a first region of a predetermined size at a predetermined position in an imaging range of an imaging unit;   make a display unit an image in the set first region as live-view image;   fix a position of the first region in the imaging range before a first operation is performed;   after the first operation is performed, displace the position of the first region in the imaging range so as to track movement of a specific subject in the imaging range; and   when a second operation is performed, follow the first operation, record a partial image corresponding to the first region in an entire image taken by the imaging unit.
