图像识别模组由光学镜头、CMOS传感器（SPCA561A）、图像处理芯片（SPCA563A）组成。 SPCA563A分析和处理SPCA561A传过来的图像信号，并得出相应的信息（颜色、形状等等）。此模组接口简单，应用方便，容易与 MCU 结合使用，我们下面将要介绍的 Demo 就是其与SPCE061A结合的例子。 -Image recognition module by the optical lens, CMOS sensor (SPCA561A), image processing chip (SPCA563A) component. SPCA563A analysis and treatment SPCA561A Chuan-up image signal, and came to the corresponding information (color, shape, etc.). This module interface is simple, convenient, easy to used in conjunction with the MCU, we introduce the following to be the Demo is its combination with SPCE061A example.
