Abstract
本公开的实施例涉及视觉传感器芯片及其操作方法和电子设备。该视觉传感器芯片包括：像素阵列电路，被配置为通过测量光强变化量来生成与其中的多个像素对应的多个数据信号，多个数据信号指示至少一个光强变化事件，至少一个光强变化事件表示像素阵列电路中的对应像素测量到的光强变化量超过预定阈值；以及读取电路，耦合到像素阵列电路并且被配置为：以第一读取模式从像素阵列电路读取多个数据信号中的至少一个数据信号，向控制电路提供至少一个数据信号，如果从控制电路接收到基于至少一个数据信号而生成的模式切换信号，将第一读取模式切换为第二读取模式。通过在第一和第二读取模式之间自适应地切换，视觉传感器芯片的传输和存储成本能够得到有效降低。
