Abstract

A method and a system for displaying an infrared (IR) image and/or a related image on a touch screen are provided. For example, a method may include: displaying, on a touch screen, an image of a scene; partitioning the image into a first part and a second part in response to a user indication made on the touch screen; displaying the first part of the image in an IR image mode using an IR image of the scene capture by an IR imaging sensor; and displaying the second part of the image in a non-IR image mode. The non-IR image mode may include a visible light (VL) image mode for displaying a VL image of the scene, or a fusion image mode for displaying a combination of the IR image and the VL image. The partitioning may be adjusted in response to a swipe gesture made on the touch screen.

Claims

1. A method comprising:

displaying, on a touch screen, an image of a scene;

partitioning the image into a first part and a second part in response to a user indication made on the touch screen;

displaying the first part of the image in an infrared (IR) image mode using at least a portion of an IR image of the scene captured by an IR imaging sensor; and

displaying the second part of the image in a non-IR image mode.

2. The method of claim 1, further comprising:

detecting a swipe gesture made on the touch screen, wherein the detecting of the swipe gesture comprises periodically determining a current location of the swipe gesture; and

continuously updating the partitioning and the displaying of the first and the second parts based on the periodically determined current location of the swipe gesture until an ending location of the swipe gesture is detected.

3. The method of claim 1, wherein the non-IR image mode comprises:

a visible light (VL) image mode that displays a corresponding part of the image using at least a portion of a VL image of the scene captured by a VL imaging sensor;

or

a fusion image mode that displays a corresponding portion of the image using a combination of pixel data from the IR image and the VL image.

4. The method of claim 3, further comprising aligning the VL image with the IR image.

5. The method of claim 4, wherein the aligning of the VL and the IR images comprises compensating for a parallax error and/or a difference in field of view (FOV) between the VL and the IR images.

6. The method of claim 1, wherein the partitioning splits the image vertically along a line.

7. The method of claim 1, further comprising:

displaying, on the touch screen, a graphical object representing a temperature range for processing the IR image;

detecting a swipe gesture having a starting location corresponding to the graphical object;

modifying the temperature range based on the swipe gesture; and

processing the IR image based on the modified temperature range.

8. The method of claim 7, wherein the temperature range comprises a minimum temperature and/or a maximum temperature for presenting the IR image in color.

9. A system comprising:

an infrared (IR) imaging sensor configured to capture an IR image of a scene;

a touch screen; and

a processor communicatively coupled to the IR imaging sensor and the touch screen, the processor being configured to;

display, on the touch screen, an image of the scene,

partition the image into a first part and a second part in response to a user indication made on the touch screen,

display the first part of the image in an IR image mode using at least a portion of the IR image captured by the IR imaging sensor, and

display the second part of the image in a non-IR image mode.

10. The system of claim 9, wherein the processor is further configured to:

detect a swipe gesture made on the touch screen, wherein the detect the swipe gesture comprises periodically determining a current location of the swipe gesture; and

update continuously the partition and the display of the first and the second parts based on the periodically determined current location of the swipe gesture until an ending location of the swipe gesture is detected.

11. The system of claim 9, further comprising:

a first device comprising the IR imaging sensor;

a second device comprising the touch screen and a visible light (VL) imaging sensor configured to capture the VL image of the scene; and

wherein the non-IR image mode comprises;

a VL image mode that displays a corresponding part of the image using at least a portion of the VL image of the scene captured by the VL imaging sensor, or

a fusion image mode that displays a corresponding portion of the image using a combination of pixel data from the IR image and the VL image.

12. The system of claim 11, wherein the processor is configured to align the VL image with the IR image to compensate for a parallax error and/or a difference in field of view (FOV) between the VL and the IR images.

13. The system of claim 9, wherein the processor is configured to partition the image by splitting the image vertically along a line.

14. The system of claim 9, wherein the processor is further configured to:

display, on the touch screen, a graphical object representing a temperature range for processing the IR image, the temperature range comprising a minimum temperature and/or a maximum temperature for presenting the IR image in color;

detect a swipe gesture having a starting location corresponding to the graphical object;

modify the temperature range based on the swipe gesture; and

colorize the IR image based on the modified temperature range.

15. A non-transitory computer-readable medium storing instructions which, when executed by one or more processors of a device, causes the device to perform a method comprising:

displaying, on a touch screen, an image of a scene;

partitioning the image into a first part and a second part in response to a user indication made on the touch screen;

displaying the first part of the image in an infrared (IR) image mode using at least a portion of an IR image of the scene captured by an IR imaging sensor; and

displaying the second part of the image in a non-IR image mode.

16. The non-transitory computer-readable medium of claim 15, wherein the method further comprises:

detecting a swipe gesture made on the touch screen, wherein the detecting of the swipe gesture comprises periodically determining a current location of the swipe gesture; and

continuously updating the partitioning and the displaying of the first and the second parts based on the periodically determined current location of the swipe gesture until an ending location of the swipe gesture is detected.

continuous updating of the splitting and the displaying comprises dragging the line along which the IR image is split based on the periodically determined current location of the swipe gesture.

17. The non-transitory computer-readable medium of claim 15, wherein the non-IR image mode comprises:

a visible light (VL) image mode that displays a corresponding part of the image using at least a portion of a VL image of the scene captured by a VL imaging sensor;

or

a fusion image mode that displays a corresponding portion of the image using a combination of pixel data from the IR image and the VL image.

18. The non-transitory computer-readable medium of claim 17, wherein the method further comprises aligning the VL image with the IR image to compensate for a parallax error and/or a difference in field of view (FOV) between the VL and the IR images.

19. The non-transitory computer-readable medium of claim 15, wherein the partitioning splits the image vertically along a line.

20. The non-transitory computer-readable medium of claim 15, wherein the method further comprises:

displaying, on the touch screen, a graphical object representing a temperature range for processing the IR image, the temperature range comprising a minimum temperature and/or a maximum temperature for presenting the IR image in color;

detecting a swipe gesture having a starting location corresponding to the graphical object;

modifying the temperature range based on the swipe gesture; and

colorizing the IR image based on the modified temperature range.
