ABSTRACT:
This talk presents a new wide-angle fovea sensor in which we can change attention points without mechanical parts.
The developed fovea sensor comprises a special liquid crystal lens, controller, and image processor for removing distortion in a projected image. This fovea vision system is characterized by the following properties; (1)We can change attention point as keeping its wide field of view. (2)We can change magnification factor around at the attention point. (3)The attention point is not single necessarily but multiple. Advantages of fovea sensor has been well-known with respect to data transmission and strage volume. However, the existing fovea sensors need mechanical parts in order to change the attention point, and thus it is difficult to say the fovea sensor has been distributed broadly all over the world. A special-made optical system for foveation made from liquid crystal is expected much that the fovea sensor is used in many applications, e.g. security camera, endscope, and etc. from now on. The developed fovea vision system is advantageous of downsizing and less energy comsumption becuase it does not have any mechanical part.
