Choosing a Camera

developed a range of

solutions, the most

popular of which include

hybrid cameras that

operate in colour when

lighting is adequate,

switching to monochrome

as darkness falls. Some

cameras operate in low

light by reducing the

number of frames

captured to produce a

brighter picture although

this causes problems

when there is movement

within the image.

Sony has developed a

more radical approach by

improving the sensitivity

of the CCD chip. On Chip

Lens technology (OCL)

increases the surface

area and sensitivity of the

CCD by locating a microlens on each pixel which results in more light being

collected on the photosensitive layer. This technology has been developed most

recently with the introduction of the ExwaveHAD CCD which has a highly advanced

OCL structure. The result of these developments is a degree of sensitivity that can

handle twilight light levels while still producing accurate colour images even with

rapidly moving objects.

Smear is caused by the leakage of light onto the vertical shift register, creating

a vertical bar across the image which can render it useless and is a common

problem with cameras in low light or where there are bright spots in the picture.

With ExwaveHAD, this leakage is reduced because the improvement in the

structure of the CCD minimises the undesirable reflection of light onto its surface.

As a result, smear is reduced to a minimal level of -120dB – comparable to the

frame interline transfer CCDs commonly used in broadcast cameras.

Sony now produces both colour and monochrome cameras which benefit from

the advanced technology of ExwaveHAD technology.
