How Was the World's First
Single-Tube Color Video
Camera for Home Use,
Born?
Yasuo Takemura
OCT Imaging Research Lab
Abstract-It was Toshiba IK-12 who overcame such a common sense that the shooting of
a TV camera was a job of expert engineers. TV cameras using image pickup tubes were
already put into practical use in the 1970s. It had many functions to adjust the size, light
intensity, color tone, etc., and it could only be operated by an experienced professional
engineers. Under such circumstances, the world's first home-use color video camera IK12
released in 1974 was the small and light weight. It included various innovations. The
number of adjustment points has been reduced as much as possible so that anyone can
use it, and a compact and lightweight design has been devised so that even women can
use it. The IK12 opened up a new market for home video cameras and created an era
where everyone could shoot. The basic technologies and ideas of digital cameras and
mobile phones were built at this time. How was the groundbreaking single-tube color
video camera for home born? I would like to verify these from a technical point of view.
I think these will often be helpful for young researchers and engineers who will lead the
next generation.
& IN THE SPRING of 1974, the first color video
camera in Japan to be connected to a home VCR
for easy shooting was released in Japan.1

At that time, it was common sense to attach a
color camera to a tripod for shooting, but even
women can easily take pictures by hand, and no
maintenance is required. Anyone can take a
color image at any time by switching ON, and the
selling price could be reduced to one-third at a
stretch.
