Newly Developed ASICs
Three VLSI (Very Large Scale Integration) chips have
been developed by Ikegami for the digital process,
digital encoder, and data rate converter IC’s. Cutting-
edge VLSI technology with 300,000 gates per chip, 3
volt power, and up to 60MHz sample frequency allows
extended digital functions and performance with the
equivalent power consumption of conventional analog
circuits.

Video Processing by DSP
A single ASIC provides 16-bit video processing
including functions of flare correction, linear matrix,
gamma correction, detail enhancement,knee, and auto
iris.
The HK-388 with
Full Digital Power
The HK-388 and HK-388P are 12-bit
full digital processing cameras that
combine Ikegami’s vast studio camera
experience with today’s digital
technology.
By incorporating newly developed digital
processing IC’s (ASIC’s), these cameras
achieve consistently high picture quality
and reliability that only digital
processing can deliver.
A 10MHz ultra-wideband component
triax system and a fiber optic digital
transmission system are introduced
together with the HK-388.
Both systems deliver high resolution
pictures even at long cable lengths.
●
Digital Encoders
Both camera head and base station incorporate the new
digital encoder ASIC providing highly stable
performance with NTSC encoded outputs available as
standard at the camera as well as base station.
●
Standard with Digital Outputs
In addition to the full compliment of analog outputs, the
system comes standard with four component serial
digital (270 Mbps) outputs from the base station. This is
accomplished by the development of a data rate
converter ASIC which changes the digital component
video from CCD sample frequency to D1 sample
frequency. The identical ASIC is used at the camera to
convert the aspect ratio between 4:3 and 16:9 in the
HK-388W and HK-388PW.
