The present subject matter includes a method of focusing of an optical imaging apparatus. The method comprises causing illumination of an object using an illuminating beam to thereby cause generation of a scattered beam. A first set of luminous parameters are derived from a first detected position of a luminous representation formed by the scattered beam from the object. The illumination-beam is focused upon the object by triggering a movement of the object along an optical-axis in a first direction, the first direction being based a numerical-representation of the first set of luminous parameters. A second set of luminous parameters are derived from a second detected position of the luminous-representation of the object, the second detected position being related to the first detected position and the movement of the object. The focusing of the illumination beam is ceased based at-least on a numerical-representation of the second set of luminous parameters.

A device for inspecting a display device includes a camera to photograph a substrate and generate image information, a pixel value setter to set pixel values corresponding to respective luminances of a plurality of pixels from the image information, and to detect a crack region based on the pixel values, a stress calculator to calculate a critical stress of a crack included in the crack region, and a determiner to check whether the critical stress is equal to or greater than a first threshold value and to determine whether the substrate has defects.

An electronic device that includes a vision system carried by a bracket assembly is disclosed. The vision system may include a first camera module that captures an image of an object, a light emitting element that emits light rays toward the object, and a second camera module that receives light rays reflected from the object. The light rays may include infrared light rays. The bracket assembly is designed not only carry the aforementioned modules, but to also maintain a predetermined and fixed separation between the modules. The bracket assembly may form a rigid, multi-piece bracket assembly to prevent bending, thereby maintaining the predetermined separation. The electronic device may include a transparent cover designed to couple with a housing. The transparent cover incudes an alignment module designed to engage a module and provide a moving force that aligns the bracket assembly and the modules to a desired location in the housing.

A distributed, parallel, image capture and processing architecture provides significant advantages over prior art systems. A very large array of computational circuits—in some embodiments, matching the size of the pixel array—is distributed around, within, or beneath the pixel array of an image sensor. Each computational circuit is dedicated to, and in some embodiments is physically proximal to, one, two, or more associated pixels. Each computational circuit is operative to perform computations on one, two, or more pixel values generated by its associated pixels. The computational circuits all perform the same operation(s), in parallel. In this manner, a very large number of pixel-level operations are performed in parallel, physically and electrically near the pixels. This obviates the need to transfer very large amounts of pixel data from a pixel array to a CPU/memory, for at least many pixel-level image processing operations, thus alleviating the significant high-speed performance constraints placed on modern image sensors.

Provided are an image reconstruction method, a device and a microscopic imaging device. The method includes calculating a gray value at each fiber center in a fiber bundle (04) in a reconstructed image according to a gray value at a center position of each fiber, determined in one or more sample images; performing a spatial interpolation using the gray value at the fiber center to obtain gray values of other pixel points in the fiber bundle (04) in the reconstructed image, so as to form the reconstructed image. This image reconstruction method greatly accelerates the speed of image reconstruction, and is helpful to remove the grating (022) and fiber bundle (04) cellular grid residues in the reconstructed image and improve the imaging quality of the reconstructed image.
