Image creation with software controllable depth of field
View Patent ↗A method of controlling depth of field of an image by a computer after the image has been taken based on the data acquired while taking the image, including, acquiring multiple images from the same perspective with different focal points, selecting parameters for preparing a displayable image, constructing an image using the data of the acquired multiple images according to the selected parameters; and displaying the constructed image.
1. A method of controlling depth of field of an image by a computer after the image has been taken based on the data acquired while taking the image, comprising:
acquiring multiple images from the same perspective with different focal points;
selecting parameters for preparing a displayable image, wherein at least one parameter comprises a selectable focal point, the selectable focal point being different than the different focal points of the multiple images;
constructing an image using the data of the acquired multiple images according to the selected parameters; and
displaying the constructed image.
2. A method according to claim 1 , wherein said acquiring is performed using a single imaging device.
3. A method according to claim 1 , wherein said acquiring is performed using multiple imaging devices located next to each other and focused to different positions along a common axis.
4. A method according to claim 1 , wherein said selecting is performed before taking images.
5. A method according to claim 1 , wherein said selecting is performed after taking images.
6. A method according to claim 1 , wherein said selecting is performed automatically by the computer based on the content of the images.
7. A method according to claim 1 , wherein the selected parameters enable the user to select focal points which correspond to the focal points of the acquired multiple images.
8. A method according to claim 1 , wherein the selected parameters enable the user to select focal points which form a continuum from the closest focal point to the furthest focal point available in the acquired images.
9. The method according to claim 1 , wherein the selected parameters enables a user to select non-continuous areas along a focal point axis so that first objects in the constructed image that are in the selected areas are in focus and second objects in the constructed image that are not in the selected areas are out of focus.
10. A method according to claim 1 , wherein the selected parameters define a single continuous area that is displayed in focus.
11. A method according to claim 1 , wherein the selected parameters define more than one continuous area that is displayed in focus.
12. A method according to claim 1 , wherein the selected parameters define a continuous area that is displayed in focus up to a selected point.
13. A method according to claim 1 , wherein the selected parameters define a continuous area that is displayed in focus from a selected point.
14. A method according to claim 1 , wherein said acquiring is performed by taking multiple images sequentially while adjusting the focal point of the lens between each image.
15. A method according to claim 1 , wherein said acquiring is performed by taking multiple images simultaneously.
16. A system for controlling depth of field of an image after the image has been taken based on the data acquired while taking the image, comprising:
an imaging device to record image data;
a image sensor installed in said imaging device to convert light to digital data;
a computer to analyze the data recorded by said image sensor;
a display to display images provided by said computer
wherein said computer is adapted to construct multiple images from the data provided by said image sensor resulting from a single image, receive input from a user defining parameters for displaying an image, and construct an image to conform to the parameters using the data provided by said image sensor resulting from a single image, the user input enabling a selection of non-continuous areas along a focal point axis so that first objects in the constructed image that are in the selected areas are in focus and second objects in the constructed image that are not in the selected areas are out of focus.
17. The system according to claim 16 , wherein the parameters for displaying the image include a photographic mode include at least one of a macro photography, outdoor photography or studio photography mode.
18. The system according to claim 16 , wherein said selecting is performed automatically by the computer based on the content of the images.
19. A system for controlling depth of field of an image after the image has been taken based on the data acquired while taking the image, comprising:
an imaging device operable to acquire multiple images from the same perspective with different focal points;
an interface operable to select parameters for preparing a displayable image, wherein at least one parameter comprises a selectable focal point, the selectable focal point being different than the different focal points of the multiple images;
a processor operable to construct an image using the data of the acquired multiple images according to the selected parameters; and
a display operable to display the constructed image.
20. The system of claim 19 , the imaging device is configured to acquire the multiple images using multiple imaging sensors located next to each other and focused to different positions along a common axis.
