Method and apparatus for providing a picture cropping function
View Patent ↗A method and apparatus for providing a picture cropping function enables users to crop pictures in a convenient and direct manner using discrete navigation keys of a user input device. According to an exemplary embodiment, an apparatus includes a first processor operative to provide at least one of an audio and video output during a first mode. A second processor is operative to provide a picture cropping function during a second mode by enabling a user to crop a picture using discrete navigation keys of a user input device of the apparatus.
1. A method for operating an apparatus, comprising steps of:
providing a video signal representing a video image;
enabling a user to crop said video image using navigation keys of a user input device of said apparatus; and wherein:
said video image includes first, second, third and fourth edges;
said user input device includes first, second, third and fourth navigation keys;
said first, second, third and fourth navigation keys enable said user to adjust said first, second, third and fourth edges, respectively;
said user input device further includes a predetermined key;
a first depression of said predetermined key enables said user to confirm selection of a desired position for one of said first, second, third and fourth edges; and
a second depression of said predetermined key after said first depression enables said user to switch edge adjustment capability from said one of said first, second, third and fourth edges to another one of said first, second, third and fourth edges in an orthogonal manner.
2. The method of claim 1 , wherein each edge of said video image is cropped independently to generate a cropped video image having a different aspect ratio than said video image.
3. The method of claim 1 , wherein:
said first edge is orthogonal to said second edge;
said second edge is orthogonal to said third edge;
said third edge is orthogonal to said fourth edge; and
said fourth edge is orthogonal to said first edge.
4. The method of claim 1 , wherein said orthogonal manner represents a clockwise direction around said video image.
5. The method of claim 1 , wherein said apparatus includes a circuit sharing arrangement in which output signals from a single amplifier of said apparatus are provided to different processors of said apparatus in response to user inputs to said apparatus, and further wherein a first one of said different processors controls a video image cropping function of said apparatus and a second one of said different processors controls at least one function of said apparatus other than said video image cropping function.
6. The method of claim 1 , wherein said video image is input to said apparatus directly from a device that acquired said video image.
7. An apparatus, comprising:
first processing means for providing a video signal representing a video image;
second processing means for enabling a user to crop said video image using navigation keys of a user input device of said apparatus; and wherein:
said video image includes first, second, third and fourth edges;
said user input device includes first, second, third and fourth navigation keys;
said first, second, third and fourth navigation keys enable said user to adjust said first, second, third and fourth edges, respectively;
said user input device further includes a predetermined key;
a first depression of said predetermined key enables said user to confirm selection of a desired position for one of said first, second, third and fourth edges; and
a second depression of said predetermined key after said first depression enables said user to switch edge adjustment capability from said one of said first, second, third and fourth edges to another one of said first, second, third and fourth edges in an orthogonal manner.
8. The apparatus of claim 7 , wherein said second processing means enables said user to adjust each edge of said video image independently to generate a cropped video image having a different aspect ratio than said video image.
9. The apparatus of claim 7 , wherein:
said first edge is orthogonal to said second edge;
said second edge is orthogonal to said third edge;
said third edge is orthogonal to said fourth edge; and
said fourth edge is orthogonal to said first edge.
10. The apparatus of claim 7 , wherein said orthogonal manner represents a clockwise direction around said video image.
11. The apparatus of claim 7 , further comprising amplifying means for providing signals to said first and second processing means in response to user inputs to said apparatus.
12. The apparatus of claim 7 , wherein said video image is input to said apparatus directly from a device that acquired said video image.
13. A television signal receiver, comprising:
a first processor operative to provide a video signal representing a video image;
a second processor operative to enable a user to crop said vide image using navigation keys of a user input device of said television signal receiver; and wherein:
said video image includes first, second, third and fourth edges;
said user input device includes first, second, third and fourth navigation keys;
said first, second, third and fourth navigation keys enable said user to adjust said first, second, third and fourth edges, respectively;
said user input device further includes a predetermined key;
a first depression of said predetermined key enables said user to confirm selection of a desired position for one of said first, second, third and fourth edges; and
a second depression of said predetermined key after said first depression enables said user to switch edge adjustment capability from said one of said first, second, third and fourth edges to another one of said first, second, third and fourth edges in an orthogonal manner.
14. The television signal receiver of claim 13 , wherein said second processor enables said user to adjust each edge of said video image independently to generate a cropped video image having a different aspect ratio than said video image.
15. The television signal receiver of claim 13 , wherein:
said first edge is orthogonal to said second edge;
said second edge is orthogonal to said third edge;
said third edge is orthogonal to said fourth edge; and
said fourth edge is orthogonal to said first edge.
16. The television signal receiver of claim 13 , wherein said orthogonal manner represents a clockwise direction around said video image.
17. The television signal receiver of claim 13 , further comprising an amplifier operative to provide signals to said first and second processors in response to user inputs to said television signal receiver.
18. The television signal receiver of claim 13 , wherein said video image is input to said television signal receiver directly from a device that acquired said video image.
