    Abstract: Various implementations provide different image adjustment parameters for post-processing a multi-frame image generated from multiple individual images. A computing device includes an image sensor that is configured to capture and generate multiple images of a scene. The multiple images are then aligned and pixel values of the aligned images are combined to generate a multi-frame image with reduced image noise and improved image sharpness in comparison to each of the multiple images. The computing device then applies different adjustment parameters to the multi-frame image in order to generate an output image that provides a high-quality representation of the scene. In implementations, the computing device automatically selects and applies adjustment parameters to a multi-frame image based on a number of individual images used to create the multi-frame image.

    Abstract: Apparatus and methods are described to overcome the perception in viewed video or other presentations containing moving vehicles that the apparent rotation rate of their wheels is frequently inappropriate for the vehicle speeds, which is caused by the stroboscopic interaction between the wheel spokes and the rate at which the images are presented. A currently preferred embodiment operates off-line under human control on a previously recorded video, identifying the wheels and replacing them with suitably altered images which are perceived to rotate at rates appropriate to the vehicle speeds; or to suppress inappropriate perception of rotation. The apparatus and method results in a new recording of the original video in which the wheels appear to rotate at the correct rate for all vehicle speeds. Alternate embodiments implement a similar but automated process operating in near-real time for operating in-line on streaming videos; and variations achieving the same ends.

The thermal image obtained can be characterized so that it can be used to calibrate the phase shift from a given stack layer, or can be used to identify defects in the stacked die. The process can be repeated for each die in the stack to generate a reference for future testing. The thermal image can be investigated to detect faults, such as voids in vias, e.g., TSV.

  • Patent number: 9019365
    Abstract: The problem is solved by generating a gob image A by capturing, with a line scanning camera, an image of a falling gob that has been cut off at an orifice; generating an image B by binarizing the gob image A with a boundary value that turns a general part of the gob black and turns a peripheral lustrous portion and a defect of the gob white; generating an image C by binarizing the gob image A with a boundary value that turns the entire gob white and turns a background black and inverting the black and white; generating an image D by combining the image B and the image C together; setting a region located a given number of pixels inside an outer edge of the black area of the image D as an inspection region; and inspecting the inspection region of the gob image A to determine whether the gob is good.

  • Patent number: 9001202
    Abstract: A transfer pathway of a mounting head 10 in a component-mounting round during which the mounting head 10 moves back and forth between a component feeding unit 4 and a substrate conveyance mechanism 2 is derived by a transfer pathway calculation unit 25 for each component-mounting round from mounting program data 21a. A focusing processing unit 24 controls an optical system focusing mechanism 18, thereby matching a focusing point of a line sensor camera 14 achieved during imaging operation to the transfer pathway of the mounting head 10 based on data pertaining to the derived transfer pathway. Further, an optical system zooming mechanism 17 adjusts an imaging range according to the focusing point. Accordingly, even when a long substrate 3 is taken as an object, it is possible to detect with high precision whether or not a component exists on the pickup nozzle 11 of the mounting head 10.

    Abstract: The invention relates to a method of protecting a camera (2) for inspecting printed work during printing from soiling. A transparent protective element (7) is placed here between the camera (2) and the printed work for inspection, and the protective element (7) is replaced when the transparency thereof decreases. The transparent protective element (7) can form part of a strip of transparent film (7) which is unwound from a supply reel (9) and wound onto a take-up reel (10). The decrease in transparency can be determined on the basis of a recording made by the camera (2). The invention also relates to a device (1) for protecting such a encamera (2) from soiling, comprising a transparent protective element (7) to be placed between the camera (2) and the printed work for inspection; and means () for replacing the protective element (7) when the transparency thereof decreases.

  • Patent number: 8957960
    Abstract: A machine vision system program editing environment includes near real time context generation. Rather than requiring execution of all preceding instructions of a part program in order to generate a realistic context for subsequent edits, surrogate data operations using previously saved data replace execution of certain sets of instructions. The surrogate data may be saved during the actual execution of operations that are recorded in a part program. An edit mode of execution substitutes that data as a surrogate for executing the operations that would otherwise generate that data. Significant time savings may be achieved for context generation, such that editing occurs within an operating context which may be repeatedly refreshed for accuracy in near real time. This supports convenient program modification by relatively unskilled users, using the native user interface of the machine vision system, rather than difficult to use text-based or graphical object-based editing environments.

  • Patent number: 8953034
    Abstract: A compact, battery powered video imaging device for use in XYZ stage equipped machines (such as milling machines, jig borers, coordinate measuring machines, etc.) that mounts into the spindle of such a machine and displays a magnified image of a part on the XYZ stage of the machine on an integrated video monitor such as a Liquid Crystal Display panel equipped with crosshairs or similar reference marks. The XYZ stage of the host machine is used to move the part so that various features of the part are brought into the crosshairs of the video monitor. In such a way the XYZ coordinates of various features of the part with respect to a selected reference feature, displayed on the host machine's position readout, can be obtained. This procedure can be used to aid work piece setup, measure parts in-process without disturbing the setup, or to inspect finished parts for dimensional accuracy.
