摘要:
Disclosed is apparatus for inspecting a sample. The apparatus includes illumination optics for simultaneously directing a plurality of incident beams at a plurality of azimuth angles towards a sample and collection optics for directing a plurality of field portions of output light from two or more of the plurality of angles towards two or more corresponding sensors. The two or more sensors are arranged for receiving the field portions corresponding to two or more angles and generating two or more corresponding images. The apparatus further comprises a processor for analyzing the two or more images to detect defects on the sample.

An electronic device is provided. The electronic device includes a memory configured to store a high-speed video captured with a first number of frames per second and a processor configured to be electrically connected with the memory. The processor is configured to detect an amount of image variation based on at least one of the first number of frames and generate a slow motion interval, a playback time of which is extended, by dividing or sampling the first number of frames into a second number of frames which are less than the first number of frames with respect to a video interval having an amount of image variation which meets a specified condition.
摘要:
An electronic system that detects an object from image data captured by a camera; divides a region of the image data corresponding to the object into a plurality of sub-areas based on attribute information of the object and an image capture characteristic of the camera; extracts one or more characteristics corresponding to the object from one or more of the plurality of sub-areas; and generates characteristic data corresponding to the object based on the extracted one or more characteristics

In general, techniques are described that facilitate processing of color image data using both a mono image data and a color image data. A device comprising a monochrome camera, a color camera and a processor may be configured to perform the techniques. The monochrome camera may be configured to capture monochrome image data of a scene. The color camera may be configured to capture color image data of the scene. The processor may be configured to perform intensity equalization with respect to a luma component of either the color image data or the monochrome image data to correct for differences in intensity between the color camera and the monochrome camera.

Systems and methods are disclosed for recovering both phase and amplitude of an arbitrary sample in an optical microscope from a single image, using patterned partially coherent illumination. This is realized through the use of a encoded light source which embeds several different illumination patterns into color channels. The sample is modulated by each illumination wavelength separately and independently of each other, but all of the channels are sensed by the imaging device in a single step. This color image contains information about the phase and amplitude of a sample encoded in each channel, and can be used to recover both amplitude and phase from this single image, at the incoherent resolution limit. Further, extensions of this method are shown which allow the same recovery of a sample whilst it is moving during a single exposure using a motion deblurring algorithm.
