Abstract

Image processing apparatus and method of calculating distance information and size information of an object within an image frame are provided. The method of processing an image includes: sequentially moving a focus lens from infinity to a short distance; overlapping and storing frames including an object focused at each movement location of the focus lens; and displaying a synthesis frame that synthesizes the overlapped frames in one frame, and simultaneously, calculating relative distance information of objects focused at different locations of the focus lens based on an object focused at an arbitrary location of the focus lens, and displaying the relative distance information in the synthesis frame.

First claim

1 . A method of processing an image, the method comprising:
sequentially moving a focus lens from infinity to a short distance; overlapping and storing frames comprising an object focused at each movement location of the focus lens; displaying a synthesis frame that synthesizes the overlapped frames in one frame, and simultaneously, calculating relative distance information of objects focused at different locations of the focus lens based on an object focused at an arbitrary location of the focus lens, and displaying the relative distance information in the synthesis frame; and calculating a size of each object inside the synthesis frame, calculating an actual distance information ratio of focused other objects based on actual distance information mapped to a focused arbitrary object, and calculating and displaying actual size information of the objects by applying the ratio to a size of the each object.

2 . The method of claim 1 , wherein the overlapping and displaying comprises: when at least two objects exist at an arbitrary location of movement locations of the focus lens, overlapping and storing frames comprising a selected object.

3 . The method of claim 1 , further comprising:
establishing a database that maps actual distance information from an image processing apparatus to an object to each movement location of the focus lens.

4 . The method of claim 3 , wherein the displaying comprises:
displaying a synthesis frame that synthesizes the overlapped frames in one frame, and simultaneously, and retrieving the actual distance information mapped to the location of the focus lens when each object is focused from the database, and displaying the actual distance information in the synthesis frame.

5 . (canceled)

6 . A method of processing an image, the method comprising:
operating an opening degree of an aperture from a maximum opening to a minimum opening; overlapping and storing frames comprising an object focused under each open state of the aperture; displaying a synthesis frame that synthesizes the overlapped frames in one frame, and simultaneously, calculating relative distance information of objects focused under other open states of the aperture based on an object focused under an arbitrary open state of the aperture, and displaying the relative distance information in the synthesis frame; and calculating a size of each object inside the synthesis frame, calculating an actual distance information ratio of focused other objects based on actual distance information mapped to a focused arbitrary object, and calculating and displaying actual size information of the objects by applying the ratio to the size of the each object.

7 . The method of claim 6 , wherein the overlapping and storing comprises: when at least two objects exist under an arbitrary open state of open states of the aperture, overlapping and storing frames comprising a selected object.

8 . The method of claim 6 , further comprising:
establishing a database that maps actual distance information from an image processing apparatus to an object to each open state of the aperture.

9 . The method of claim 8 , further comprising:
mapping and storing a different shutter speed depending on each open state of the aperture when establishing the database.

10 . The method of claim 8 , wherein the displaying comprises:
displaying a synthesis frame that synthesizes the overlapped frames in one frame, and simultaneously, and retrieving the actual distance information mapped to an open state of the aperture from the database when each object is focused, and displaying the retrieved actual distance information inside the synthesis frame.

12 . An image processing apparatus comprising:
a focus lens; a lens driver sequentially moving a focus lens from infinity to a short distance; a distance information calculator overlapping and storing frames comprising an object focused at each movement location of the focus lens, and displaying a synthesis frame that synthesizes the overlapped frames in one frame, and simultaneously, calculating and displaying relative distance information of objects focused at different locations of the focus lens based on an object focused at an arbitrary location of the focus lens; and a size information calculator calculating a size of each object inside the synthesis frame, calculating an actual distance information ratio of focused other objects based on actual distance information mapped to a focused arbitrary object, and calculating and displaying actual size information of the objects by applying the ratio to the size of the each object.

13 . The apparatus of claim 12 , wherein the distance information calculator overlaps and stores frames comprising a selected object when at least two objects exist at an arbitrary location of movement locations of the focus lens.

14 . The apparatus of claim 12 , wherein the distance information calculator establishes a database that maps actual distance information from an image processing apparatus to an object to each movement location of the focus lens, and retrieves the actual distance information mapped to the location of the focus lens when each object is focused from the database, and displays the actual distance information inside the synthesis frame.

15 . (canceled)

16 . An image processing apparatus comprising:
an aperture; an aperture driver operating an opening degree of an aperture from a maximum opening to a minimum opening; a distance information calculator overlapping and storing frames comprising an object focused under each open state of the aperture, display a synthesis frame that synthesizes the overlapped frames in one frame, and simultaneously, calculating and displaying relative distance information of objects focused under other open states of the aperture based on an object focused under an arbitrary open state of the aperture; and a size information calculator calculating a size of each object inside the synthesis frame, calculating an actual distance information ratio of focused other objects based on actual distance information mapped to a focused arbitrary object, and calculating and displaying actual size information of the objects by applying the ratio to the size of the each object.

17 . The apparatus of claim 16 , wherein the distance information calculator overlaps and stores frames comprising a selected object when at least two objects exist under an arbitrary open state of open states of the aperture.

18 . The apparatus of claim 16 , wherein the distance information calculator establishes a database that maps actual distance information from the image processing apparatus to an object to each open state of the aperture, and retrieves the actual distance information mapped to an open state of the aperture when each object is focused from the database, and displays the retrieved actual distance information inside the synthesis frame.

19 . The apparatus of claim 18 , wherein the distance information calculator maps and stores a different shutter speed depending on each open state of the aperture when establishing the database.
