摘要： A recording device for distance images becomes multi-target-enabled by means of the arrival of light pulses reflected at object regions at different distances being temporally resolved. This is done using extrema of the gradient of a correlation function between the received light pulses and a time window during which sensor elements of a camera are activated.

摘要： A defect judgement processing method and apparatus which can optimize image processing and defect judgement parameters for a detection image cut out by each inspection window to avoid erroneous judgement and defect missing and to realize reliable defect judgement. An image data generator cuts out ranges indicated by a plurality of predesignated inspection windows from a detected image and stores them in a memory, a window data generator generates window data having inspection conditions attached thereto with respect to the plurality of inspection windows and stores them in the memory, a feature extractor reads out detection images of the ranges indicated by the inspection windows from the memory and extracts a structural feature parameter therefrom on the basis of an image processing parameter conforming to the inspection condition obtained by the window data, and a defect judger performs its defect judging operation over the extracted structural feature parameter on the basis of a defect judgement parameter conforming to the inspection condition.

摘要： A solder testing apparatus comprising image processing means for performing image processing on an image of an appearance of a soldered portion to identify shape characterizing amounts for the soldered portion; and defect determining means for performing good/bad determination on the soldered portion from data derived by the image processing means and data from test parameter storing means for storing shape characterizing amounts at design time, wherein tested-object standard shape estimating means is included for extracting shape characterizing amounts of a non-defective soldered portion by statistically processing shape characterizing amounts for soldered portions identified by the image processing means, and defect determining parameters stored in the test parameter storing means are updated based on standard shape values from the tested-object standard shape estimating means, so that a highly reliable test is realized by setting defect determining parameters based on actual shapes and dimensions of leads and pads of electronic components on a printed circuit board.
