Abstract

To enable a user to rapidly scan to a desired frame of a video, multiple recordings of the video are provided, each at progressively better resolution. When the user is scanning for a frame, the lowest resolution recording is used to provide the display; when the user arrives at a desired frame, the higher resolution recordings are used. A subsequent user selection of a different frame causes the display of the higher resolution images to be interrupted, and the lowest resolution recording is used to provide an image corresponding to the different frame. The lesser resolution recordings may include a reduction in either spatial or temporal resolution, or both, and may include ‘motion blur’ that provides a visually ‘smoother’ continuous scan. Each higher resolution frame replaces the lower resolution frame that is displayed while waiting for the higher resolution frame to be downloaded.

Claims

1. A client device comprising:

an input element that receives user input,

a communication element that communicates with a server,

a memory element that stores data received from the server,

a display element that provides images based on the data, and

a controller that is configured to;

request a view of an object from the server, based on the user input,

receive a section of a first mosaic of the object corresponding to the view at a first resolution from the server,

display a first image on the display element based on one or more frames of the section of the first mosaic,

receive a section of a second mosaic of the object corresponding to the view at a second resolution from the server, and

display a second image on the display element based on one or more frames of the section of the second mosaic, replacing the display of the first image.

2. The client device of claim 1, wherein the controller is further configured to:

receive an other user input that includes a new identification of another desired view of the object,

request another view of an object from the server, based on the other user input,

receive an other section of the first mosaic from the server,

display a third image on the display element based on the other section of the first mosaic, replacing the display of the second image,

receive an other section of the second mosaic from the server based on the other user input, and

display a fourth image on the display element based on the other section of the second mosaic, replacing the display of the third image,

wherein if another user input is received that includes another identification of a further desired view of the object before the other section of the second mosaic is received, the receiving of this other section and the display of the fourth image are terminated.

3. The client device of claim 1, wherein the controller is further configured to:

receive a section of a third mosaic of the object at a third resolution from the server, and

display a third image on the display element based on the section of the third mosaic, replacing the display of the second image,

wherein the first and second resolutions differ by a first resolution parameter, and the second and third resolutions differ by a second resolution parameter that differs in type from the first resolution parameter, and

the first and second resolution parameters include at least two of;

a spatial resolution parameter, a temporal resolution parameter, and a pixel quality parameter.

4. The client device of claim 1, wherein each section of each mosaic includes one or more image frames, and at least one section of at least one of the mosaics includes a plurality of image frames that are spatially adjacent.

5. The client device of claim 4, wherein the plurality of frames is based on a spatial difference between the desired view and at least one prior desired view.

6. The client device of claim 1, wherein the controller is configured to receive other sections of at least the first and second mosaics without a specific request from the user.

7. The client device of claim 6, wherein the other sections of the at least first and second mosaics are selected using a prediction based on prior input from one or more users.

8. A server comprising:

a first communication element that communicates with a client,

a second communication element that communicates with a database, the database including a plurality of mosaics corresponding to an object, each of the mosaics of the plurality of mosaics having a different resolution,

a control element that;

receives a request for a view of the object via the first communication element,

obtains a section of each of the mosaics based on the request for the view via the second communication element, and

communicates the section of each of the mosaics via the first communication element in increasing order of resolution, such that the section of the mosaic having a lowest resolution is communicated first, and the section of the mosaic having a highest resolution is communicated last.

9. The server of claim 8, wherein the control element is configured to terminate obtaining and communicating the sections upon receipt of an other request for an other view of the object.

10. The server of claim 9, wherein receipt of the other request causes the control element to:

obtain an other section of each of the mosaics based on the other request, and

communicate the other section of each of the mosaics via the first communication element in increasing order of resolution, such that the other section of the mosaic having a lowest resolution is communicated first, and the other section of the mosaic having a highest resolution is communicated last.

11. The server of claim 8, wherein the resolutions of at least two mosaics differ by a first resolution parameter, and the resolutions of at least two mosaics differ by a second resolution parameter that differs in type from the first resolution parameter, and

the first and second resolution parameters include at least two of:

a spatial resolution parameter, a temporal resolution parameter, and a pixel quality parameter.

12. The server of claim 8, wherein each section of each mosaic includes one or more image frames, and at least one section of at least one of the mosaics includes a plurality of image frames that are spatially adjacent.

13. The server of claim 12, wherein the plurality of frames is based on a spatial difference between the desired view and at least one prior desired view.

14. The server of claim 8, including a processing element that receives a first mosaic of the plurality of mosaics at a first resolution and creates each of the other mosaics of the plurality of mosaics based on the first mosaic.

15. The server of claim 8, wherein at least one mosaic includes a first type of resolution parameter and at least one other mosaic includes a second type of resolution parameter, and the first and second types of resolution parameter include two of:

a spatial resolution, a temporal resolution, and a pixel quality resolution.

16. A non-transitory computer readable medium that includes a program that, when executed by a processor, causes the processor to:

create a first mosaic at a first resolution that includes a plurality of frames corresponding to images of an object from different views;

create a second mosaic at a second resolution from the first mosaic, the second resolution being less than the first resolution; and

storing the first mosaic and the second mosaic at a database server that enables retrieval of a section of each of the mosaics corresponding to a select view of the object at a select resolution.

17. The medium of claim 16, where the program causes the processor to create a third mosaic at a third resolution from one of the first mosaic and the second mosaic, wherein the second mosaic includes a first type of resolution, the third mosaic includes a second type of resolution, and the first and second types of resolution include two of:

a spatial resolution, a temporal resolution, and a pixel quality resolution.
