Under the trend of globalization, camera manufacturers increasingly rely on the East Asian electronics supply chain, where countries and regions such as Japan, South Korea, and China have a distinct competitive advantage in electronics manufacturing and serve as crucial nodes in the global supply chain. For instance, Sony in Japan controls over 50% of the global image sensor market, while other key components, such as display screens, are primarily sourced from suppliers in South Korea and China. In the case of digital single-lens reflex (DSLR) cameras, key components like image sensors, processors, lenses, screens, and batteries are supplied by companies from various global regions. The globalized supply chain not only improves production efficiency but also effectively reduces production costs through resource integration.

However, a globalized supply chain also brings numerous challenges. First, logistics management becomes more complex as cross-border supply chains require components to be transported globally to assembly factories. Second, the risk of supply chain disruptions increases, as natural disasters or political factors can cause the global supply chain to stall. The 2011 Japanese earthquake and the 2020 COVID-19 pandemic further exposed its vulnerabilities. Additionally, the globalized supply chain heavily depends on a few key suppliers, such as Sony and Samsung in the image sensor market, posing substantial production risks for camera manufacturers. Thus, how to mitigate this risk by diversifying supplier layouts and optimizing supply chain management has become a key issue for camera manufacturers.

Based on the above analysis, this paper aims to analyze the camera supply chain, identify challenges and opportunities in supply chain management, and discuss how manufacturers can utilize modern technology to improve supply chain efficiency, reduce risks, and achieve sustainable development. The study will also propose improvement suggestions, providing theoretical support and practical guidance for camera manufacturers to optimize their supply chains.
