CCD array Preparing for readout with 2x2 binning Sometimes individual pixels can accumulate too much charge which then overflows into neighbouring pixels This can result in an effect known as blooming where a bright object in the middle of the image seems to flare over all other objects in the image If this happens you need to reduce the amount of light that falls onto the CCD m By reducing the exposure time m By disabling or reducing the binning factor CCD arrays like film and other media are always sensitive to light therefore they must not be exposed to light during read out For most cameras exposure to light is controlled electronically or by a mechanical shutter The shutter ensures that no light falls on the CCD array as the charges are transferred to the read out array Some cameras may allow you keep the shutter open so that exposure continues while the charges are being transferred to the read out array However this may result in smearing where bright objects leave a trail across the image This effect can CCD Cooling PRINCIPLES OF CCD THEORY be reduced to some extent by making sure that the exposure time is longer than the readout time Over time there will be a thermally induced build up of charge in the CCD This is known as dark charge and may bring with it an undesirable noise component One way of checking for dark noise is to close the shutter and expose for a long period You will see speckles on
