<正>Image sensing is a critical component of modern machine vision technology development.The traditional silicon-based photodiodes possess inflexible responsivity and energy band structures that are hard to manipulate by an external field,limiting the system’s ability to process picture data [1].Additionally,existing memristor arrays can do some computation in hardware but cannot directly respond to optical signals,so it is necessary to use additional image sensors to convert optical signals into electrical signals before implementing further signal processing.As a result of their separate data processing units and image sensors,conventional image sensing systems face problems such as slow operation and excessive power consumption that can result in transmitting and processing huge amounts of duplicate information [2,3].
