Image sensing apparatus
View Patent ↗A clipping processing portion is provided with: a main subject detection portion which detects the location of a main subject from an input image; a clip region setting portion which sets the clip region that is a region including the main subject; and a clipping portion which clips an image of the clip region from the input image to produce a clipped image. There is further provided a zoom control portion which controls the optical zoom magnification of the image sensing portion based on the clip region set by a clip region setting portion, and the optical zoom magnification is controlled such that the input image has an appropriate angle of view.
1. An image sensing apparatus, comprising:
an image sensing portion which obtains an input image by image sensing;
a clipping processing portion which sets a clip region in said input image obtained by the image sensing portion so that a plurality of clip regions are sequentially set as said clip region in a plurality of input images which are sequentially obtained as said input image by the image sensing portion, and which clips said clip region from the input image to produce a clipped image; and
a control portion which controls optical zoom magnification when the image sensing portion performs image sensing,
wherein
the control portion controls the optical zoom magnification based on an amount of change in size of said clip region set in said input image,
the control portion controls the optical zoom magnification further based on an amount of change in location of the clip regions that are sequentially set as said clip region in the input images obtained as said input image,
the control portion reduces the optical zoom magnification in image sensing performed by the image sensing portion on detecting that said clip region is set in a vicinity of an edge of said input image and that locations of the plurality of clip regions which are sequentially set as said clip region in the plurality of input images which are sequentially obtained as said input image by the image sensing portion approach said edge of said input image one after another,
on detecting that at least part of said clip region is set in a region having a predetermined width from an edge of said input image, the control portion reduces the optical zoom magnification in image sensing performed by the image sensing portion, and
the predetermined width is set based on at least either the amount of change in size of the clip regions that are sequentially set as said clip region or the amount of change in location of the clip regions that are sequentially set as said clip region.
