Camera manufacturers have advanced the technology-related diversification with increasing the sales of cameras. Today, camera manufacturers have shifted their business strategy. The technology-related diversification has been promoted in earnest since the 70's. But it has not proceeded smoothly. Camera manufacturers cited four main reasons for the technology-related diversification: the unique characteristics of the products and manufacturers, the market size and market maturity since the 70's, the development of technologies, i. e. the automation of camera operation, at the highest stages, and the decrease of profitability.Each manufacturer made the utmost use of its technology, and advanced to the highly profitable fields. The management gap has been formed by the product development competition and the degree of the technology-related diversification. Camera manufacturers show a strong competitive power in the diversified fields. The optical technologies of camera industries have become a barrier against the other industries entering the field, and a strength in the diversified fields.
