Extraction of video picture screen saver function
View Patent ↗The apparatus and method for extracting a single picture image from a video file saved in a storage device ( 20 ) of the electronic device ( 10 ) and performing a screen saver function using the extracted single picture image. The screen saver function may extract a plurality of single picture images from the saved video files of the electronic device. The plurality of single picture images can be provided from the random and/or sequential location of the video file data ( 10 ).
1. A method for an electronic device, the method comprising the steps of:
receiving a screen saving signal;
extracting a single picture image from a video file saved in a storage device associated with the electronic device in response to receipt of the screen saving signal, wherein the single picture image is an I-frame and the video file is an MPEG file;
converting the extracted picture image to a format compatible with a display driver of a display associated with the electronic device;
performing in response to receipt of the screen saving signal a screen saving function using the extracted single picture image so as to display the extracted single picture image on a display associated with the electronic device; and
repeating the steps of extracting, converting, and performing until a screen saving end signal is received, wherein a user preference determines whether to repeat extracting a single picture image from a random location of the video file, sequential locations of the video file, or a combination of random and sequential locations of the video file.
2. The screen saving method of claim 1 , wherein the step of performing a screen saving function includes displaying the single picture image in a random location on the display associated with the electronic device.
3. The screen saving method of claim 1 , wherein the storage device comprises a DVD.
4. The screen saving method of claim 1 , further comprising the step of applying a fade-in/fade-out function to each extracted picture image for presentation to the display associated with the electronic device.
5. A screen saving method for an electronic device, the method comprising the steps of:
receiving a screen saving signal;
searching contents of recorded media for a video file saved in a storage device associated with the electronic device in response to receipt of the screen saving signal;
extracting a single picture image from a located video file in response to receipt of the screen saving signal, wherein the single picture image is an I-frame and the video file is an MPEG file;
converting the single picture image to a format compatible with a display driver for a display associated with the electronic device;
performing in response to receipt of the screen saving signal a screen saving function using the extracted single picture image so as to display the extracted single picture image on a display associated with the electronic device; and
repeating the steps of extracting, converting, and performing until a screen saving end signal is received, wherein a user preference determines whether to repeat extracting a single picture image from a random location of the video file, sequential locations of the video file, or a combination of random and sequential locations of the video file.
6. The screen saving method of claim 5 , wherein the storage device comprises a DVD.
7. The screen saving method of claim 5 , wherein the step of searching includes receiving from a user a recorded media type to be excluded and the step of excluding from searching any recorded media type based on user selected preference.
8. The screen saving method of claim 5 , wherein the step of performing a screen saving function includes displaying the single picture image in a random location on the display associated with the electronic device.
9. An electronic device comprising:
a control unit;
a storage device; and
a screen saver application for:
receiving a screen saving signal from the control unit,
extracting a single picture image from a video file accessible by the storage device in response to receipt of the screen saving signal, wherein the single picture image is an I-frame and the video file is an MPEG file,
converting the extracted picture image to a format compatible with a display driver of a display associated with the electronic device and
performing in response to receipt of the screen saving signal a screen saving function using the single picture image so as to display the extracted single picture image on a display associated with the electronic device,
wherein the screen saver application is further able to repeat extracting single picture images from the video source, converting the extracted picture image and performing the screen saver function with the extracted single picture images until a screen saving end signal is received from the control unit, wherein a user preference determines whether to repeat extracting a single picture image from a random location of the video file, sequential locations of the video file, or a combination of random and sequential locations of the video file.
10. The electronic device of claim 9 , wherein the screen saver application displays the single picture image in a random location on the display associated with the electronic device.
11. The electronic device of claim 9 , wherein the storage device comprises a DVD.
12. The electronic device of claim 9 , wherein the screen saver application is further operable to apply a fade-in/fade-out function of the extracted single picture image during the performance of the screen saving function.
