Information Handling System Defocus Tracking Video
A portable information handling system presents visual images with defocus adjustments by defining one or more objects based on image blur at the object edges. The defined object is tracked based upon the object edges and the visual image outside the area of the defined object is adjusted to have a defocus that emphasizes the presentation of the defined object. In addition, the defined object provides a basis for other adjustments, such as color presented in association with the object or metadata that presents additional information with the defined object.
1 . A portable information handling system comprising:
a planar housing;
a processor disposed in the planar housing and operable to execute instructions to process information;
a memory disposed in the planar housing and interfaced with the processor, the memory operable to store the information;
a graphics processor interfaced with the processor and operable process information into pixel values for presentation of the information at display pixels as a visual image;
a display disposed at one side of the planar housing and interfaced with the graphics processor and memory, the display operable to present the information as the visual image;
a focus mapper interfaced with the graphics processor and operable to detect plural defined objects in the visual image based on image blur at object edges; and
a focused image adjuster interfaced with the graphics processor and operable to defocus the visual image outside one or more selected of the plural defined objects.
2 . The portable information handling system of claim 1 further comprising a camera, the camera providing the visual image to the graphics processor, the focus mapper detecting the plural defined objects from the camera visual image, the focused image adjuster adjusting the visual image to save in the memory.
3 . The portable information handling system of claim 2 wherein the visual image comprises a video received in real time from the camera, the focus mapper tracking the one or more selected of the plural defined objects in each of plural video frames captured by the camera.
4 . The portable information handling system of claim 1 wherein the focused image adjuster is further operable to apply a color adjustment for the visual image portion that is defocused.
5 . The portable information handling system of claim 1 wherein the focused image adjuster is further operable to associate a metadata with the one or more of selected of the plural defined objects.
6 . The portable information handling system of claim 5 wherein the visual image comprises a video having plural frames, and the focus mapper is further operable to track the one or more selected of the plural defined objects in each of the plural video frames and insert the metadata in the image proximate the one or more of the plural defined objects.
7 . The portable information handling system of claim 6 wherein the video comprises a video captured in real time by a camera.
8 . The portable information handling system of claim 1 further comprising a selection page presented at the display by the focus mapper, the selection page having the plural defined objects highlighted to allow an end user to select defined objects at the display.
9 . A method for presenting a visual image at a portable information handling system, the method comprising:
presenting the visual image at a display of the portable information handling system;
detecting one or more defined objects in the visual image by detecting image blur at an edge of each of the one or more defined objects;
presenting the one or more defined objects identified as such at the display;
accepting a selection of one or more of the defined objects by an end user; and
in response to the selection, defocusing the visual image outside of the one or more defined objects.
10 . The method of claim 9 further comprising:
capturing the visual image with a camera and presenting the visual image in real time at the display; and
automatically tracking the selected one or more defined objects by reference to the image blur as the selected one or more defined objects move in the visual image.
11 . The method of claim 10 further comprising:
associating a meta data with the selected one or more defined objects; and
presenting the meta data at the display proximate the selected one or more defined objects as the selected one or more defined objects move in the visual image.
12 . The method of claim 10 further comprising:
defining an active area in a central portion of the display; and
defocusing selected one or more defined objects that move out of the active area.
13 . The method of claim 9 further comprising applying a color adjustment to the defocused portion of the visual image.
14 . The method of claim 13 wherein the color adjustment comprises presentation of the visual image as black and white in the defocused portion.
15 . The method of claim 9 further comprising:
detecting an acceleration of greater than a predetermined amount at the portable information handling system;
storing the visual image in a storage device as a video having plural frames over a time period that includes the acceleration; and
removing from the storage device one or more of the frames associated with the time period of the acceleration.
16 . The method of claim 9 wherein the visual image comprises a video having plural frames stored in a storage device and retrieved for post-processing.
17 . A system for managing presentation of a visual image at a portable information handling system, the system comprising:
non-transitory memory storing instructions operable to:
present the visual image at a display of the portable information handling system;
detect one or more defined objects in the visual image by detecting image blur at an edge of each of the one or more defined objects;
present the one or more defined objects identified as such at the display;
accept a selection of one or more of the defined objects by an end user; and
in response to the selection, defocus the visual image outside of the one or more defined objects.
18 . The system of claim 17 wherein the non-transitory memory instructions are further operable to:
capture the visual image with a camera and present the visual image in real time at the display; and
automatically track the selected one or more defined objects by reference to the image blur as the selected one or more defined objects move in the visual image.
19 . The system power system of claim 17 wherein the non-transitory memory instructions are further operable to:
detect an acceleration of greater than a predetermined amount at the portable information handling system;
store the visual image in a storage device as a video having plural frames over a time period that includes the acceleration; and
remove from the storage device one or more of the frames associated with the time period of the acceleration.
20 . The system power system of claim 17 wherein the non-transitory memory instructions are further operable to apply a color adjustment to the defocused portion of the visual image.
