ABSTRACT:
A measuring system (200) for measuring a FOV of a digital camera module (52) includes a measuring chart (22), a parameter inputting module (32), and a processing module (42). The measuring chart defines a colored portion. The parameter inputting module is used to input relative parameters. The processing module is connected to the parameter inputting module and receives electronic image signals converted from images of the colored portion and of the measuring chart screened by the lens module. The processing module is configured for calculating the FOV θ of the digital camera module. A measuring method for measuring the FOV θ of the digital camera module is also provided.
