【 摘 要 】

Human vision is remarkable. By limiting the main concentration of high-acuity photoreceptors to the eye;;s central fovea region, we efficiently view the world by redirecting the fovea between points of interest using eye movements called saccades.

Part I describes a saccadic vision system prototype design. The dual-resolution saccadic camera detects objects of interest in a scene by processing low-resolution image information; it then revisits salient regions in high-resolution. The end product is a dual-resolution image in which background information is displayed in low-resolution, and salient areas are captured in high-acuity. This lends to a resource-efficient active vision system.

Part II describes CMOS image sensor designs for active vision. Specifically, this discussion focuses on methods to determine regions of interest and achieve high dynamic range on the sensor.
