Abstract: of the correlation image sensor(Ando et al., 2009). In this paper, using the newest device of it, we present a theory and experimental evaluation of a bio-inspired vibro-visual correlation imager with various feature extraction capability. Mimicking the involuntary movement (microsaccade) of human eyes, it vibrates rapidly and finely a mirror in its visual axis so as to generate an equivalent vibration of every pixel in a doubly circular locus. The time-varying intensity is captured by a correlation image sensor (CIS) with synchronous reference signals to the vibration, and complex first/second order differentials and Laplacian are obtained as the image features. General theoretical foundations and an implementation result of this system using a novel 640×512 pixel device are presented. Several experimental results using it including a realtime control of resolution and edge detection from a combined use of the first and second order differentials are shown.
