NEC placed emphasis on increased reliability and stability as the basic design concept for developing completely self-contained color camera for ENG. The result of examinations led us to think that power consumption reduced to the minimum and reduced heating are the prime requirements to realize the above aims. For without attaining those requirements, miniaturization of camera and driving over long period through battery those are essential for ENG camera are impossible. NEC owes it to NHK that NEC introduced the technical direction of "μ-POWER" as the fundamental design philosophy. Under the joint effort with NHK, NEC started development of μ-Power LSI of Process Amplifier in the summer of 1974 and the test product was developed in the spring of 1975. This product clearly indicated the possibility of LSI'd video circuit. with this knowledge, NEC expanded the scope of development of LSI including encoder, preamplifier, synchronizing system and deflection system to develop next generation color camera and the prototype of μ-Power LSI'd color camera was developed in October 1975. Commercialized first lot will be completed in the spring of 1976. The prototype camera is 3-tube color camera employing 2/3ʺ Plumbicon* that power consumption is approximately 25 W.
