20130128027Image Processing Apparatus And Image Processing Method - Provided is an image processing apparatus which can prevent deterioration in defect detection accuracy. The image processing apparatus includes an imaging unit and an image processing unit. The imaging unit converts a color image imaged by the imaging element to an HDR image based on a conversion characteristic for expanding a dynamic range, to output the HDR image. The image processing unit inversely converts color component values with respect to each pixel of the HDR image outputted from the imaging unit, based on the conversion characteristic, calculates brightness and a ratio of the color component values with respect to each pixel from the inversely converted color component values, and converts the calculated brightness based on the conversion characteristic, to generate a post-correction HDR image based on a ratio of the converted brightness and the calculated color component values.05-23-2013
20130128028Image Processing Apparatus - Provided is an image processing apparatus which can easily perform focus adjustment only by switching a program in accordance with a kind of an inspection object.

A plurality of pieces of inspection condition data are set, the data being made up of a plurality of setting items including a focus position data. When the switching instruction from one inspection condition data to another inspection condition data is accepted, the operation of the focus adjustment mechanism is controlled based on focus position data included in another inspection condition data after switching.05-23-2013
20130169793INSPECTION SYSTEM AND INSPECTION METHOD - An inspection system captures an inspected object which is illuminated by an illumination system and processes an image of the inspected object which is expressed by the obtained image data to inspect it. The inspection system includes a processing information determining portion determining processing information which is used for the inspection processing which changes along with the change of the amount of illumination light from the illumination system from the initial amount of light to the target amount of light when the set amount of light of the illumination system is changed from the initial amount of light to the target amount of light, and which system performs the inspection processing by using processing information which is determined by the processing information determining means in accordance with the elapsed time from when the set amount of light of the illumination system is switched to the target amount of light.07-04-2013
20100033565Infrared Defect Detection System and Method for the Evaluation of Powdermetallic Compacts - A pulsed thermography defect detection apparatus including active and passive infrared (IR) thermography for non-destructive testing (NDT) of powdermetallic (P/M) components for on-line and off-line inspection.02-11-2010
20110249115APPARATUS FOR CRACK DETECTION DURING HEAT AND LOAD TESTING - Material testing under variable heat and load while continuously monitoring crack formation is provided using an apparatus that permits thermal control somewhat uniformly over a conductive sample, while permitting a controlled load to be applied to the sample in tensional or flexural modes. Thermographic imaging of a sample in situ within a standard thermo-mechanical fatigue (TMF) test rig or other heat and load test apparatus is used to detect and monitor cracks as they form. A 360° sample view is possible. Image analysis software may identify, count and/or characterize cracks. Thermographic images may be analyzed to determine a sample temperature, e.g. for temperature feedback control. Essentially passive thermography is used with an inductive heating coil that surrounds at least 60% of a length of the sample, with at least two windings, the windings having thickness and pitch so that at least half the sample is in view.10-13-2011
