1. A method for determining an illumination setting for capturing an image of a component, belonging to a specific package type, in a pick-and-place machine, the illumination setting being an illumination setting associated with said specific package type, the method comprising:
capturing a first image of a first component of said specific package type while the first component is illuminated by a first illumination condition;
capturing a second image of the first component while the first component is illuminated by a second illumination condition, the second illumination condition being different from the first illumination condition;
perform software manipulation of the first image and the second image to generate a plurality of generated images of the first component based on combining the first image and the second image at different intensities, wherein each one of the plurality of generated images comprises a specific combination of an intensity of the first image and an intensity of the second image, corresponding to a specific combination of an illumination intensity level of the first illumination condition and an illumination intensity level of the second illumination condition;
selecting at least one of the plurality of generated images that fulfils a particular quality measure as a selected generated image; and
determining, based on the selected generated image, the illumination setting associated with said specific package type as a determined illumination setting, wherein the determined illumination setting comprises a first illumination intensity level for the first illumination condition corresponding to an intensity of the first image in the selected generated image and a second illumination intensity level for the second illumination condition corresponding to an intensity of the second image in the selected generated image.
