Abstract
A method for changing the depth at which an image is focused is provided in a portable imaging device that includes an image recording arrangement that has a lens system, an image sensor for recording images, and a display arrangement for presentation of the recorded images. The method includes moving a movable focusing frame covering a part of a recorded image presented on the display to identify an area of interest in the presented image. The method also includes analyzing the image within the frame to obtain a setting required to focus the image within the frame and applying the obtained setting to the full presented image to focus the presented image at the depth defined by the current position of the movable focusing frame.
Claims18
A method for changing the depth at which an image is focused in a portable imaging device, the imaging device comprising:
- an image recording arrangement comprising a lens system and an image sensor for recording images, and a display arrangement for presentation of the recorded images, the method comprising:
- moving a movable focusing frame covering a part of a recorded image presented on the display to identify an area of interest in the presented image;
- analyzing the image within the frame to obtain a setting required to focus the image within the frame;
- and
- applying the obtained setting to the full presented image to focus the presented image at a depth defined by a current position of a movable focusing frame.
A portable imaging device, comprising:
- an image recording arrangement comprising a lens system and an image sensor for recording images,
- a display for presentation of the recorded images,
- an image processing unit for changing the depth at which an image is focused in the portable imaging device, wherein the image processing unit is configured to:
- move a movable focusing frame covering a part of a recorded image presented on the display to identify an area of interest in the presented image;
- analyze the image within the frame to obtain a setting required to focus the image within the frame;
- and
- apply the obtained setting to the full presented image to focus the presented image at a depth defined by a current position of the movable focusing frame.
A computer program product comprising a computer readable medium, having thereon computer program code to make a portable imaging device execute, when said program code is loaded in a portable communication device comprising:
- an image recording arrangement comprising a lens system and an image sensor for recording images, and a display for presentation of the recorded images, a method comprising:
- moving a movable focusing frame covering a part of a recorded image presented on the display to identify an area of interest in the presented image;
- analyzing the image within the frame to obtain a setting required to focus the image within the frame;
- and
- applying the obtained setting to the full presented image to focus the presented image at a depth defined by a current position of the movable focusing frame.
A computer program element comprising computer program code means to make a portable communication device execute, when said program element is loaded in the portable communication device comprising:
- an image recording arrangement comprising a lens system and an image sensor for recording images and a display for presentation of the recorded images, a method comprising:
- moving a movable focusing frame covering a part of a recorded image presented on the display to identify an area of interest in the presented image;
- analyzing the image within the frame to obtain a setting required to focus the image within the frame;
- and
- applying the obtained setting to the full presented image so as to focus the presented image at a depth defined by a current position of the movable focusing frame.
