Abstract
An image sensor device for outputting digital signals and a method thereof are disclosed. The image sensor device has a sensor module, a photoelectric converter module, an encoder module and a decoder module integrated with each other. The digital signals are outputted by the photoelectric converter module, are transferred to the series outputs by the encoder module, and then the decoder module takes the place of the ADC for transferring the series outputs to parallel digital signal outputs. Hence the present invention improves the defects (such as transmission interference, transmission decay and power consumption) of the analog signal, and removes the ADC from the image sensor device for reducing production costs. Furthermore, the image sensor device has some advantages for providing good image quality, easy assembly and reducing both power consumption and cost.
