Abstract

Particularly for miniature camera modules, manufactured in high volumes, characterization and measurement approaches are needed that provide information on camera key properties efficiently. An integrated measurement system named has been developed that uses images taken on specifically designed test chart targets, which are then automatically analysed by software. The chart combines target elements for measurement of optoelectronic conversion function, resolution, noise, uniformity, distortion and colour reproduction. The software applies machine vision to recognize the various target elements from the images, and to register analysis locations properly. The actual analysis methods conform with existing standards. The software includes graphical user interface, and in addition to the automatic analysis, also user-defined analysis can be flexibly done. The software supports modifications in the chart layout, batch analysis of images and storing the results in spreadsheet report format.
