capturing an original image;
modifying the original image based on the comparison performed, wherein the modified image has an adjusted aspect ratio different from an aspect ratio of the original image, and wherein modifying the original image includes:
normalizing a width of the original image to the display area width to produce a first intermediate image;
cropping any excess height of the first intermediate image that is greater than the display area height;
normalizing a height of the original image to the display area height to produce a second intermediate image;
cropping any excess width of the second intermediate image that is greater than the display area width;
comparing the first intermediate image and the second intermediate image to determine which image preserves more relevant image information; and
selecting the image that preserves more relevant image information as the modified image to send to the display device; and
sending the modified image to the display device.
2. The method of claim 1 , wherein the at least one display parameter includes at least one of a display area aspect ratio, width, height, display resolution, or maximum frame size parameter associated with the display device.

5. The method of claim 4 , wherein if the image capture width is equal to the display area width, and if the image capture height is greater than the display area height, then modifying the original image includes cropping an excess height of the captured image that is greater than the display area height.
6. The method of claim 4 , wherein if the image capture height is equal to the display area height, and if the image capture width is greater than the display area width, then modifying the original image includes cropping any excess width of the captured image that is greater than the display area width.
7. The method of claim 1 , wherein the aspect ratio of the original image is a ratio of a width of the original image and a height of the original image, and wherein the adjusted aspect ratio of the modified image is a ratio of a width of the modified image and a height of the modified image.
8. The method of claim 7 , wherein the aspect ratio and adjusted aspect ratio are measured as a ratio of one of pixels, density-independent pixels (dp), scale-independent pixels (sp), inches or millimeters, or points.
9. The method of claim 1 , wherein modifying the original image further includes performing facial recognition techniques to recognize placement of the face prior to modifying the original image.
10. The method of claim 9 , wherein the facial recognition techniques may include using a Haar Cascade algorithm to detect a person within the original image.
11. A method for dynamically adjusting an aspect ratio of an image during a video call comprising:
obtaining at least one display parameter of a display device having a display area;
determining that an image capture height is greater than a display area height, and that an image capture width is less than a display area width based on a comparison of the at least one display parameter to at least one image capture parameter of a capture device;
capturing an original image;
modifying the original image based on the comparison performed, wherein the modified image has an adjusted aspect ratio different from an aspect ratio of the original image, and wherein modifying the original image includes:
cropping the original image based on the display area height and the display area width to produce a first intermediate image;
rotating the original image;
cropping the rotated image based on the display area height and the display area width to produce a second intermediate image;
comparing the first intermediate image and the second intermediate image to determine which image preserves more relevant image information; and
selecting the image that preserves more relevant image information as the modified image to send to the display device; and
sending the modified image to the display device.
