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.

Aspects of the subject disclosure may include, for example, obtaining image content over a communication network, determining a predicted viewpoint of a user associated with the image content, and adjusting the image content to equirectangular image content according to the predicted viewpoint. Further aspects can include downscaling the equirectangular image content according to a display capability of a mobile device resulting in a downscaled equirectangular image content, cropping the downscaled equirectangular image content resulting in a cropped equirectangular image content, and providing, over the communication network, the cropped equirectangular image content to the mobile device. Other embodiments are disclosed.

In some implementations, a 360-degree camera includes two wide-angle lenses that provide a spherical view of a scene. The 360-degree camera is configured to be connected to a computing device for rendering the captured images. The user interface provides for the ability to present several camera views simultaneously, where each camera view is operated independently from the other camera views, such that the view may be changed during display by the user by changing the orientation. A plurality of rendering processes is executed in parallel to provide the data for each of the views and the output from each process is combined for presentation on the display. Additionally, a plurality of different combinations of multiple view layouts are provided, such as a circular view inside a rectangular view, a view that splits the display into equal separate views, and three or four independent camera views displayed simultaneously.

A method of processing an image by a device obtaining one or more images including captured images of objects in a target space, generating metadata including information about mapping between the one or more images and a three-dimensional (3D) mesh model used to generate a virtual reality (VR) image of the target space, and transmitting the one or more images and the metadata to a terminal.

An image processing apparatus includes a conversion unit, a generation unit, and a processing unit. The conversion unit is configured to convert an original image received from a plurality of cameras into a top view image. The generation unit is configured to generate a surround view monitor (SVM) image by synthesizing a bottom image extracted from the top view image and a wall image extracted from the original image.
