An image capturing device includes an imaging device and circuitry. The imaging device captures an image. The circuitry defines a point of interest in the image, converts the defined point of interest in accordance with attitude information of the image capturing device, and cuts out a viewable area from the image. The viewable area includes the converted point of interest.

A method for splitting a wide angle view of a scene into a plurality of display views is provided. The wide angle view is captured by a wide angle lens camera. The method comprises detecting, over time, objects in the scene; determining positions of the detected objects; determining one or more areas of interest within the scene based on the determined positions of the objects; and determining splitting boundaries for the plurality of display views in the wide angle view such that the splitting boundaries avoids the one or more areas of interest. A monitoring camera having a wide angle lens is also provided.

Methods for creation and use (e.g., for navigation) of displays of flattened (e.g., curvature-straightened) 3-D reconstructions of tissue surfaces, optionally including reconstructions of the interior surfaces of hollow organs. In some embodiments, data comprising a 3-D representation of a tissue surface (for example an interior heart chamber surface) are subject to a geometrical transformation allowing the tissue surface to be presented substantially within a single view of a flattened reconstruction. In some embodiments, a catheter probe in use near the tissue surface is shown in positions that correspond to positions in 3-D space sufficiently to permit navigation; e.g., the probe is shown in flattened reconstruction views nearby view regions corresponding to regions it actually approaches. In some embodiments, automatic and/or easily triggered manual view switching between flattened reconstruction and source reconstruction views is implemented.

An image processing method includes obtaining an original image; partitioning the original image into a first part and a second part such that distortion of at least a part of an image in the first part of the original image is smaller than a predetermined threshold, and distortion of at least a part of an image in the second part of the original image is greater than or equal to the predetermined threshold; correcting the second part of the original image so as to obtain a distortion-corrected image corresponding to the second part; and recognizing the first part of the original image and the distortion-corrected image so as to recognize an object in the original image.

An information processing apparatus configured to paste a full-spherical panoramic image along an inner wall of a virtual three-dimensional sphere; calculate an arrangement position for arranging a planar image closer to a center point of the virtual three-dimensional sphere than the inner wall, in such an orientation that a line-of-sight direction from the center point to the inner wall and a perpendicular line of the planar image are parallel to each other, the planar image being obtained by pasting an embedding image to be embedded in the full-spherical panoramic image, on a two-dimensional plane; and display a display image on a display unit. The display image is a two-dimensional image viewed from the center point in the line-of-sight direction in a state in which the full-spherical panoramic image is pasted along the inner wall of the virtual three-dimensional sphere and the planar image is arranged at an arrangement position.

There is provided a generation apparatus, a generation method, a reproduction apparatus, and a reproduction method by which a display image generated by use of an omnidirectional image is made approximately uniform in image quality in all visual line directions. A down-conversion part down-converts an omnidirectional image. A perspective projection part generates multiple images by projecting on multiple two-dimensional planes the omnidirectional image mapped onto a 3D model. This disclosure may be applied, for example, to generation apparatuses that generate an omnidirectional image from captured images in six directions so as to generate low- and high-resolution streams of the omnidirectional image.

This disclosure provides an apparatus and method for performing object detection based on images captured by a fisheye camera and an electronic device. The apparatus includes a memory and a processor coupled to the memory. The processor according to an embodiment is configured to: project an original image captured by the fisheye camera onto a cylindrical or spherical projection model, and perform reverse mapping to obtain at least two reversely mapped images, angles of view of the at least two reversely mapped images being towards different directions, detect objects in the reversely mapped images, respectively, and detect an object that is the same among the objects detected in the reversely mapped images. According to this disclosure, information in the wide field of view images obtained by capturing by the fisheye camera may be fully utilized.

The present disclosure relates to image encoding or decoding for efficiently encoding 360-degree video and mitigating image quality deterioration due to discontinuity artifacts.

An image display apparatus and a method of displaying an image are provided. The image display apparatus includes: a display; a graphics processing unit (GPU); and a processor configured to: determine a copy region of a planar-format image based on information regarding a current viewpoint, control the GPU to generate a sphere-format image by mapping an image corresponding to the copy region to a sphere and to generate an output image by rendering the sphere-format image, and control the display to display the output image.

A method and apparatus are provided for creating a floor plan from a spherical image. A spherical format is created of an image obtained by a camera, wherein the spherical format has a centre that corresponds to the position from which the image was obtained by the camera, and wherein a first surface represented in the image had a first orientation and was at a first distance from the camera when the image was obtained. A plurality of selected points are obtained in the spherical format, each defined by spherical coordinates consisting of a yaw angle and a pitch angle defining a line from the centre. A plane is identified that has the first orientation and that is at the first distance from the centre of the sphere. For each of the selected points, a location in a Cartesian coordinate system is identified where the line from the centre of the sphere to the selected point intersects with the first plane, two of the axes of the Cartesian coordinate system being parallel to the first plane. A floor plan is rendered using the locations, which represents the positions of the selected points on the first surface.
