Recent Evolution on Image Sensing

Abstract

The current growth of the image sensor market is mainly driven by demands for the mobile imaging market. The driving force is further expected to continue more than several years from now. Thus, it is worthy to consider what kinds of demands come from the mobile imaging market to understand what kinds of imaging technologies are required.
On the other hand, sensing applications, which utilize image sensor date not only for taking pictures but also for person identification, product inspection, obstacle avoidance and so on, are emerging. They seem to growth in industry and automotive markets at first but expected in mobile market soon. In sensing applications, non-RGB image sensors are utilized as well as RGB image sensors.
In this talk, recent evolutions of image sensors for both RGB and other than RGB are introduced. First, RGB imaging technologies which have been implemented in recent image sensor products for mobile market are introduced. Second, some new-generation image sensors which are to acquire information other than RGB are introduced. Also, expectations that such new-generation image sensors are promising for mobile imaging applications in the future are explained by introducing some recent researches in vision-based imaging area.
