Apparatus and methods for rolling shutter compensation for multi-camera systems
Images may be obtained using a moving camera comprised of two or more rigidly mounted image sensors. Camera motion may change camera orientation when different portions of an image are captured. Pixel acquisition time may be determined based on image exposure duration and position of the pixel in the image array (pixel row index). Orientation of the sensor may at the pixel acquisition time instance may be determined. Image transformation may be performed wherein a given portion of the image may be associated with a respective transformation characterized by the corrected sensor orientation. In some implementations of panoramic image acquisition, multiple source images may be transformed to, e.g., equirectangular plane, using sensor orientation that is corrected for the time of pixel acquisition. Use of orientation correction may improve quality of stitching by, e.g., reducing contrast of border areas between portions of the transformed image obtained by different image sensors.
Open-field handheld fluorescence imaging systems and methods
A drape configured to cover a handheld imager for use in a medical procedure, the drape including a frame that is removably mountable to a front portion of an enclosure of the imager; and at least one light transmissive component mounted to the frame and recessed with respect to a front of the frame such that the at least one light transmissive component is positioned in front of at least one enclosure window of the imager when the frame is mounted to the front portion of the imager.
System for communication skills training using juxtaposition of recorded takes
An Internet-based application allows a trainee to record a performance of a scene containing roles A and B with performers for the scene's roles alternately speaking their respective lines. The system displays the lines in a teleprompter style, and based on the experience level of the trainee, may blank out increasing portions of the teleprompter-style lines. If the trainee is assigned role A, the system will present each role A line to be spoken by the trainee with a time progress bar indicating the speed/timing or time remaining for that line. The trainee's performance is recorded by a computer. The teleprompter timer ensures that the trainee's performance is coordinated with a take of role B, even though the trainee's take and the role B take are actually recorded at different times. The takes are played in tandem for evaluating effectiveness of the training.
Polarized illumination and detection for depth sensing
A depth camera assembly (DCA) for depth sensing of a local area. The DCA includes a polarized light generator, an imaging device, and a controller. The polarized light generator modulates one or more optical beams emitted from an illumination source to generate modulated light, and projects the modulated light into the local area as polarized light having a first polarization. The imaging device receives light from the local area, the received light including ambient light and a portion of the polarized light reflected from the local area. The imaging device reduces an intensity of the received light having polarization different from a second polarization to generate filtered light substantially composed of light of the second polarization, and detects the portion of the polarized light having the second polarization using the filtered light. The controller determines depth information for the local area based on the detected portion of the polarized light.
Reticle backside inspection method
A method of inspecting a reticle includes obtaining a first image of a surface of the reticle at a first height by scanning the reticle surface with a light source at the first height of the reticle surface relative to a reference surface height of the reticle surface and obtaining a second image of the reticle surface at a second height by scanning the reticle surface with the light source at the second height of the reticle surface relative to the reference surface height of the reticle surface. The second height is different from the first height. The first and the second images are then combined to obtain a surface profile image of the reticle.
Gas detection device, information processing device, and program
Provided are a gas detection device, an information processing device, and a program which enable a user to accurately estimate a gas leak position. The gas detection device includes a hardware processor that causes a display screen to display a first image captured by a first imaging section and a second image captured by a second imaging section, and changes at least one of a first display position of a specific position included in the first image and a second display position of the specific position included in the second image on the display screen. The hardware processor causes the display screen to display the first display position and the second display position so that the first display position and the second display position can be compared with each other so as to recognize a difference between the first display position and the second display position.
Image management device, image management method, program, and recording medium
An account association unit associates the user account of a service user with the user account of a service provider in a case where the service user starts using a service provided by the service provider. An analysis unit sets, as a target image, an image, which is stored after the user account of the service user is associated with the user account of the service provider, among images stored in the image storage unit for the user account of the service provider, and analyzes an object shown in the target image. An image transmission unit transmits the target image to the image storage unit for the user account of the service user at a preset time point for image transmission in a case where the object relating to the service user is shown in the target image.
Wide view registered image and depth information acquisition
A camera system produces omnidirectional RGBD (reg-green-blue-depth) data, similar to a LiDAR but with additional registered RGB data. The system uses multiple cameras, fisheye lenses and computer vision procedures to compute a depth map. The system produces 360 RGB and depth, from a single viewpoint for both RGB and depth, without requiring stitching. RGB and depth registration may be obtained without extra computation and result presents zero parallax misalignment.
Image capture and ordering
One or more techniques and/or systems are provided for ordering images for panorama stitching and/or for providing a focal point indicator for image capture. For example, one or more images, which may be stitched together to create a panorama of a scene, may be stored within an image stack according to one or more ordering preferences, such as where manually captured images are stored within a first/higher priority region of the image stack as compared to automatically captured images. One or more images within the image stack may be stitched according to a stitching order to create the panorama, such as using images in the first region for a foreground of the panorama. Also, a current position of a camera may be tracked and compared with a focal point of a scene to generate a focal point indicator to assist with capturing a new/current image of the scene.
Image processing method and imaging device
An image processing method for processing a first image captured by a camera is provided, in which the first image is retrieved; and an output image is output to an image output circuit after the first image is modified to the output image, wherein a result value of each pixel of the output image is zero or a value generated by subtracting the threshold value from the brightness value of each pixel of the first image.
