Multiple Objects Tracking Sensor Module 1.0 General Description 1.1 Introduction PAJ7025 is a multiple objects tracking (MOT) sensor which integrates a high quality CMOS image sensor, image processing DSP and SPITM protocol. As the figure below depicts, PAJ7025 captures grey image by built-in sensor and analyzes objects with PixArt image processing DSP. Object features including object area, object center coordinate, 4-way object boundary, average/maximum object brightness, object radius, object range, and aspect ratio are accessible through SPITM interface. In the application environment the moving object(s) could have active IR light source or passive IR reflector. Master Slave SPI Interface Feature Setting Report Banks Bank Figure 1.
