After reading the Translation of the article about the Samsung camera, I came away with the feeling that it was speculation based on info from a person supposed to be a industry insider. A speculation that was proved wrong last spring, but now being rumored again? I tried a different translation of the article, but it was also difficult to understand what was really being said.
The speculation is based on cuts in spending of marketing for the cameras. Samsung's has been working to clean up their many different units and boost profits. Their phone business has relied on growth for profits, and that's not happening.
The imaging unit is certainly losing money, it will take a ton of money to design lenses, and establish a share of the marketplace. You cannot become profitable instantly, it will take years. If their financial considerations did not take this into account, and assumed a instant profit, they have experienced a rude awakening.
The problem is that Samsung's market share for mirrorless cameras is decreasing, if it were increasing, there would be some hope. Developing new sensors is expensive, and they become obsolete quickly. A large volume of production is needed to recoup startup costs for a new sensor. I suspect that is another issue, asking for money to develop the next generation of sensors is falling on deaf ears.
