Capturing images using variable aperture devices
Disclosed are systems, apparatuses, processes, and computer-readable media for processing image data. One illustrative method of processing image data includes: capturing a first image of a subject using a variable aperture lens configured with a first aperture and a first exposure value; capturing a second image of the subject using the variable aperture lens configured with a second aperture and a second exposure value, wherein the second aperture is smaller than the first aperture and the second exposure value is smaller than the first exposure value; and generating a high dynamic range (HDR) image at least in part by fusing the first image and the second image fusing the first image and the second image.
1 . A method for processing image data, comprising:
displaying a first set of images captured using a first lens with a first aperture, the first lens having a variable aperture;
initiating a change in aperture of the first lens from the first aperture to a second aperture;
capturing, based on initiating the change in the aperture of the first lens, at least one substitute image using a second lens, wherein the first lens is part of a first camera, the second lens is part of a second camera, and the first camera is different from the second camera;
modifying the at least one substitute image to correspond to a field of view associated with the first lens;
displaying the modified at least one substitute image until a condition associated with the change in the aperture of the first lens is satisfied; and
displaying, based on a determination that the condition is satisfied, at least one image captured using the first lens with the second aperture.
2 . The method of claim 1 , wherein the second lens has a larger field of view than the first lens.
3 . The method of claim 2 , wherein the second lens has a wide-angle lens and a fixed aperture.
4 . The method of claim 1 , wherein modifying the at least one substitute image comprises cropping a region from the at least one substitute image to correspond to the field of view associated with the first lens.
5 . The method of claim 1 , wherein the condition includes the variable aperture completing movement from the first aperture to the second aperture.
6 . The method of claim 1 , wherein the condition includes an exposure value of the at least one image captured using the first lens with the second aperture being equal to or within a threshold of an exposure value of at least one image from the first set of images.
7 . The method of claim 1 , wherein the condition includes the variable aperture completing movement from the first aperture to the second aperture and an exposure value of the at least one image captured using the first lens with the second aperture being equal to an exposure value of at least one image from the first set of images.
8 . An apparatus for processing image data, comprising:
at least one memory; and
at least one processor coupled to at least one memory and configured to:
output for display a first set of images captured using a first lens with a first aperture, the first lens having a variable aperture;
initiate a change in aperture of the first lens from the first aperture to a second aperture;
capture, based on initiating the change in the aperture of the first lens, at least one substitute image using a second lens, wherein the first lens is part of a first camera, the second lens is part of a second camera, and the first camera is different from the second camera;
modify the at least one substitute image to correspond to a field of view associated with the first lens;
output for display the modified at least one substitute image until a condition associated with the change in the aperture of the first lens is satisfied; and
output for display, based on a determination that the condition is satisfied, at least one image captured using the first lens with the second aperture.
9 . The apparatus of claim 8 , wherein the second lens has a larger field of view than the first lens.
10 . The apparatus of claim 9 , wherein the second lens has a wide-angle lens and a fixed aperture.
11 . The apparatus of claim 8 , wherein the at least one substitute image is modified by cropping a region from the at least one substitute image to correspond to the field of view associated with the first lens.
12 . The apparatus of claim 8 , wherein the condition includes the variable aperture completing movement from the first aperture to the second aperture.
13 . The apparatus of claim 8 , wherein the condition includes an exposure value of the at least one image captured using the first lens with the second aperture being equal to or within a threshold of an exposure value of at least one image from the first set of images.
14 . The apparatus of claim 8 , wherein the condition includes the variable aperture completing movement from the first aperture to the second aperture and an exposure value of the at least one image captured using the first lens with the second aperture being equal to an exposure value of at least one image from the first set of images.
15 . A non-transitory computer-readable medium of a network entity having stored thereon instructions that, when executed by one or more processors, cause the one or more processors to:
output for display a first set of images captured using a first lens with a first aperture, the first lens having a variable aperture;
initiate a change in aperture of the first lens from the first aperture to a second aperture;
capture, based on initiating the change in the aperture of the first lens, at least one substitute image using a second lens, wherein the first lens is part of a first camera, the second lens is part of a second camera, and the first camera is different from the second camera;
modify the at least one substitute image to correspond to a field of view associated with the first lens;
output for display the modified at least one substitute image until a condition associated with the change in the aperture of the first lens is satisfied; and
output for display, based on a determination that the condition is satisfied, at least one image captured using the first lens with the second aperture.
16 . The non-transitory computer-readable medium of claim 15 , wherein the second lens has a larger field of view than the first lens.
17 . The non-transitory computer-readable medium of claim 16 , wherein the second lens has a wide-angle lens and a fixed aperture.
18 . The non-transitory computer-readable medium of claim 15 , wherein the at least one substitute image is modified by cropping a region from the at least one substitute image to correspond to the field of view associated with the first lens.
19 . The non-transitory computer-readable medium of claim 15 , wherein the condition includes the variable aperture completing movement from the first aperture to the second aperture.
20 . The non-transitory computer-readable medium of claim 15 , wherein the condition includes an exposure value of the at least one image captured using the first lens with the second aperture being equal to or within a threshold of an exposure value of at least one image from the first set of images.
21 . The non-transitory computer-readable medium of claim 15 , wherein the condition includes the variable aperture completing movement from the first aperture to the second aperture and an exposure value of the at least one image captured using the first lens with the second aperture being equal to an exposure value of at least one image from the first set of images.
