An input video frame is received from the input video that has a first field of view and an input lens distortion caused by a lens used to capture the input video frame. A selection of a sub-frame representing a portion of the input video frame is obtained that has a second field of view smaller than the first field of view. The sub-frame is processed to remap the input lens distortion to a desired lens distortion in the sub-frame. The processed sub-frame is the outputted.

Systems and methods for modifying image distortion (curvature) for viewing distance in post capture. Presentation of imaging content on a content display device may be characterized by a presentation field of view (FOV). Presentation FOV may be configured based on screen dimensions of the display device and distance between the viewer and the screen. Imaging content may be obtained by an activity capture device characterized by a wide capture field of view lens (e.g., fish-eye). Images may be transformed into rectilinear representation for viewing. When viewing images using presentation FOV that may narrower than capture FOV, transformed rectilinear images may appear distorted. A transformation operation may be configured to account for presentation FOV-capture FOV mismatch. In some implementations, the transformation may include fish-eye to rectilinear transformation characterized by a transformation strength that may be configured based on a ratio of the presentation FOV to the capture FOV.
