A microminiature CCD color camera system with the world's smallest camera head, utilizing a CCD image sensor, has been developed.The thumb-sized camera head (only 17.5 mm in diameter and 53 mm in length) incorporates a small wide-angle 7.5 mm focal lens, a 200,000 picture element CCD image sensor with color filter array and compact electronic circuits.The tiny head is connected to the paperback book sized camera control unit by a slim cable (4 mm in diameter).The system can produce high-quality color pictures which are applicable to a wide range of fields, such as TV broadcasting, au tomated production, robotics education and medicine. NTSC output Fig. 2 Micro-miniature color camera circuit diagramThe thumb-sized camera head is only 17.5 mm in diameter, 53 mm in length and 25 g in weight. It incorporates a special packaged CCD image sensor having 490 V X 380 H picture elements, a newly developed 7.5 mm wide-angle taking lens with manual focusing and iris adjustable mechanism and a compact electronic circuit.Considering the lens utility, size and weight, focal length f =7.5 mm and F-number F = 1.6 were decided upon.Focusing is adjustable manually from 20 mm to 00. With the extremely near position, 20 mm, 40 times enlarged images can be displayed on a 20 in. color television monitor screen.

“…However, there are several problerns, such that camera heads are large and heavy in spite of the fact that the image sensor size is very small. A new subminiature CCD color camera has been developed combining various technologies, accumulated in the field of CCD color television pickup systems [2]~ [5] .…”

Photodetectors, based on photon absorption or thermal emission, are made from semiconductor materials that are very sensitive in the spectral range from ultraviolet to far infrared. Detector figures of merit such as responsivity, noise, noise equivalent power and detectivity, and ideal performance and cooling requirements are given. Modes of operation include charge‐coupled device, photovoltaic diode, photoconductor, and bolometer. Most semiconductor detectors operate as photon detectors where the minimum photon energy detected is defined by a discrete activation energy of the semiconductor. However, micromachined bolometers and superlattice infrared detectors are in development for thermal imaging and chemical spectroscopy. Materials and detector types are discussed. Detector material preparation technologies are presented for intrinsic detectors where the photon absorption coefficient is high, and for the low absorption coefficient detectors such as impurity‐doped Ge or Si. Fabrication technology making possible large photodetector focal planes that detect photons and perform signal processing are integrated structures either in monolithic form or in hybrid form. The monolithic arrays range up to 10 6 detectors. The hybrid focal planes, mostly for infrared detection, contain up to 10 5 . Photodetector arrays have been developed for imaging across the spectrum and are used in CCD cameras, chemical spectroscopy, missile seekers, and night vision equipment.
