METHOD AND APPARATUS FOR ROLLING SHUTTER COMPENSATION
Disclosed are a system, apparatus, and method for rolling shutter compensation. An image having a plurality of scanlines captured at different times may be received from a rolling shutter camera where each scanline includes a plurality of 2D pixels, and where each scanline has an associated camera pose. One or more 2D pixels in a first scanline of the received image to 3D coordinates may be unprojected and the 3D coordinates may be transformed from the first scanline to a reference pose. The transformed 3D coordinates may be reprojected, and in response to the reprojecting, reference timeframe corrected 2D coordinates for the one or more 2D pixels in the first scanline may be provided.
IMAGE STABILIZATION METHOD AND ELECTRONIC DEVICE THEREFOR
An electronic device includes: a camera; a display; and at least one processor electrically connected to the camera and the display. The at least one processor is configured to: obtain an image data from the camera; output a preview image of the image data on the display, based on a configured magnification; detect at least one object of the preview image in a state in which the configured magnification is greater than a reference magnification; and perform an image stabilization on the preview image, based on the detected at least one object of the preview image.
SYSTEMS AND METHODS FOR STABILIZING VIDEOS
A video may be captured by an image capture device in motion. A stabilized view of the video may be generated by providing a punchout of the video. The punchout of the video may compensate for rotation of the image capture device during capture of the video. The size of the punchout of the video may be changed based on different rotational positions of to provide a view that includes different extents of the captured visual content. The changes in the size of the punchout may simulate changes in zoom of the visual content.
REAL-TIME VIDEO STABILIZATION FOR MOBILE DEVICES BASED ON ON-BOARD MOTION SENSING
Real-time video stabilization for mobile devices based on on-board motion sensing. In accordance with a method embodiment of the present invention, a first image frame from a camera at a first time is accessed. A second image frame from the camera at a subsequent time is accessed. A crop polygon around scene content common to the first image frame and the second image frame is identified. Movement information describing movement of the camera in an interval between the first time and the second time is accessed. The crop polygon is warped to remove motion distortions of the second image frame is warped using the movement information. The warping may include defining a virtual camera that remains static when the movement of the camera is below a movement threshold. The movement information may describe the movement of the camera at each scan line of the second image frame.
Polyhedron lens architecture and lens scanning method suitable for the polyhedron lens architecture
A polyhedron lens architecture is disposed in a virtual sphere. The virtual sphere has a horizontal plane, an upper hemisphere above the horizontal plane and a lower hemisphere below the horizontal plane. The polyhedron lens architecture has an upper half part above the horizontal plane, and a lower half part below the horizontal plane. The polyhedron lens architecture includes: multiple bases, which are respectively disposed on the upper half part and the lower half part; and multiple lenses respectively disposed on surfaces of the bases. Optical axes of the lenses intersect at a central point, which is located at the horizontal plane and is a structural center of the polyhedron lens architecture.
Information processing apparatus and information processing method
It is possible to easily reproduce and edit image data that is a moving image obtained by capturing an image of a non-central projection method, in which distortion correction and blur correction are reflected. For this purpose, an information processing apparatus includes: a distortion correction processing unit that performs distortion correction processing for converting image data as a moving image acquired by capturing an image of a non-central projection method into an image of a central projection method; and a blur correction processing unit that performs blur correction processing of reducing the image blur generated in the image data using posture data of an imaging apparatus for image data that has been subjected to the distortion correction processing. In other words, the blur correction is performed after the distortion correction.
Time Multiplexing Programmable Field of View Imaging
The present disclosure relates to systems and methods that employ a mechanical method for adjusting camera field angles at a high speed. The adjustments may be synchronized to a high speed image capture process. As such, multiple frames can be captured without experiencing significant object movement or hand shake. The systems and methods may be used to capture videos and/or photo stitching, because both camera position and objects in the scene are static during the high speed image capture.
POSITION DETECTION DEVICE, IMAGE FORMING APPARATUS, AND POSITION DETECTION METHOD
A position detection device includes a background member, a reader, and processing circuitry. The background member has a higher absorption characteristic in an invisible wavelength region than in a visible wavelength region. The reader opposite the background member irradiates a recording medium having a mark and the background member with light of a visible wavelength to output a visible image or with light of an invisible wavelength to output an invisible image. The processing circuitry is configured to: detect an end position of the recording medium and a position of the mark on the recording medium from a read image output from the reader; and select the visible or invisible image as the read image used for position detection, according to an absorption characteristic of a color material forming the mark read by the reader and an absorption characteristic of the recording medium in the invisible wavelength region.

There is provided an image processing apparatus that improves the efficiency of hand shake correction processing by an electronic type hand shake correcting system. The image processing apparatus including a memory section that memorizes a pixel signal output from an imaging element, a region determining section that determines a cutout region of the pixel signal memorized in the memory section on a basis of motion information of the imaging element, and an image processing section that executes image processing with regard to image quality for a pixel signal in the cutout region determined by the region determining section.
Image capturing device, image capturing method and recording medium
An image capturing device includes a housing and a processor. The processor is configured to determine whether a state of movement of the housing relative to an observation target is either a first state or a second state, and perform a control based on the state of the movement of the housing to cause change in electric energy for drive of the image capturing device.
