Jeff Bier, BDTI president, publishes an interesting view on the computer vision IP cores market: "[Vision] processor core suppliers can choose to keep the details of their products confidential, disclosing them only to prospective customers under non-disclosure agreements. And core suppliers often prefer this approach, since it allows them to keep competitors in the dark about their products.
Over time, of course, information tends to diffuse, and competitors learn about each other's products. But this takes time, and in new markets competitors may remain ignorant about each other's products for quite some time.
...Given the lack of available information about competitors' products, I was surprised to find that nearly all of the suppliers are very confident that their product is the leader—and that it has a significant lead over competitors' offerings."
Reading many image sensor announcements, this is not that much different from the computer vision IP market.
