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.

Image sensor device and a method for outputting digital signals

An image sensing module capable of fast transferring signal and a method thereof are proposed. The image sensing module comprises an optical sensor set, a plurality of readout circuits and a plurality of amplifying circuits. Each readout circuit has a plurality of input terminals and an output terminal. Each amplifying circuit has an input terminal and an output terminal. The input terminals of each readout circuit are connected with the optical sensor set. The output terminal of each readout circuit is connected to the input terminal of one of the amplifying circuits. These readout circuits simultaneously capture output signals of the optical sensor set and then transfer to corresponding amplifying circuits in a parallel way. These amplifying circuits then output the amplified signals one by one in an orderly and time-sharing way to accomplish quick transmission of signals of the image sensing module.

Image sensing module capable of fast transferring signal and method thereof

An optical mouse chip with silicon retina structure comprises an image sensor array, an accumulator and a comparing/selecting unit. The image sensor array senses a direction parameter of an image along each axis. The accumulator sums the direction parameters of the image along different axes. The comparing/selecting unit selects a largest one from the sum of direction parameters of the image along different axes to determine a moving direction of the image.
