Multi-resolution image display
First Claim
1. A computer program product residing on a non-transitory processor-readable medium and comprising instructions configured to cause a processor to:
- analyze first and second captured images from a position-tilt-zoom (PTZ) camera, wherein a perspective of the (PTZ) camera is different between the first and second captured images;
make a determination from the first captured image and the second captured image, that a set of pixels in the first captured image contains an object in motion;
select a first portion, that includes the set of pixels, of the first captured image in response to the determination that the set of pixels includes the object in motion;
select the first portion of the first captured image for display with a higher level of detail than other portions of the first captured image, the first captured image having a first resolution;
produce first image information, representing a first image of the first portion of the first captured image, using a second resolution that has a higher effective resolution than the first resolution; and
display the first image with the second resolution in a location on a display screen dependent on a location of the first portion relative to the first captured image;
wherein the first portion defines a first area and the first image defines a second area that is larger than the first area and that is at least partially outside of, and immediately adjacent to, the first area.

Abstract
An image display method includes: receiving, from a single camera, first and second image information for first and second captured images captured from different perspectives, the first image information having a first data density; selecting a portion of the first captured image for display with a higher level of detail than other portions of the first captured image, the selected portion corresponding to a first area of the first captured image; displaying the selected portion in a first displayed image, using a second data density relative to the selected portion of the first captured image; and displaying another portion of the first captured image, in a second displayed image, using a third data density; where the another portion of the first captured image is other than the selected portion of the first captured image; and where the third data density is lower than the second data density.

5. An image display method comprising:
-
receiving, from a single position-tilt-zoom (PTZ) camera, first image information for a first captured image and second image information for a second captured image, the first and second captured images captured from different perspectives, the first image information having a first resolution; analyzing the first and second image information from the first and second captured images; making a determination, from the first captured image and the second captured image, that a set of pixels in the first captured image contains an object in motion; selecting a first portion, that includes the set of pixels, of the first captured image for display with a higher level of detail than other portions of the first captured image, the first captured image having a first resolution, the selecting being in response to the determination that the set of pixels includes the object in motion; displaying the first portion of the first captured image, in a first image, using a second resolution that has higher effective resolution than the first resolution, the first portion defining a first area and the first image defining a second area that is larger than the first area and that is at least partially outside of, and immediately adjacent to, the first area; wherein displaying the first portion comprises displaying the first portion in a location on a display screen dependent on a location of the first portion relative to the first captured image. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)

15. A video surveillance system comprising:
-
a memory; a position-tilt-zoom (PTZ) camera communicatively coupled to the memory and configured to capture video images with a first resolution and to provide the video images to the memory; motion detection means, communicatively coupled to the memory, for making a determination that a set of pixels in the video images represents an object in motion, selecting means, communicatively coupled to the memory, for selecting a first portion of a respective video image of the video images in response to the determination that the set of pixels includes an object in motion, such that the first portion includes the set of pixels, the first portion defining a first area that is a first percentage of an area of the at least one of the video images; and processing means, communicatively coupled to the memory, for processing the video images for display on a display screen by; converting the first portion of at the least one of the images into a first display image defining a second area and a second resolution higher than the first resolution; and converting a second portion of the at least one of the stored video images into a second display image defining a third area, the second area being a second percentage of a sum of the second area and the third area, the second percentage being higher than the first percentage; and at least one display communicatively coupled to the processing means and configured to display the first display image and the second display image concurrently; wherein the processing means are for causing the display to display the first display image in a location on the display screen dependent on a location of the first portion relative to the respective video image such that at least some of the second area is outside of, and immediately adjacent to, the first area. - View Dependent Claims (16, 17, 18, 19, 20)
