Abstract: PURPOSE: A sigma-delta analog to a digital converter and a solid-state image pickup device are provided to obtain a high definition digital signal by using a decimation filter. CONSTITUTION: In a sigma-delta analog to a digital converter and a solid-state image pickup device, a sigma-delta modulator(51) changes a first analog input signal into a first bit streams having a first pattern through a sigma-delta modulation. A sigma-delta modulator changes a second analog input signal into a second bit stream having a second pattern through a sigma-delta modulation. A decimation filter(61) outputs a first digital value by integrating the number of the bit including a specific value included in the first bit stream. The decimation filter calculates a complement value at each bit of the first digital value, and the decimation filter uses the complement value at each bit of the first digital value as an initial value of the second digital value. The decimation filter outputs the second digital value by integrating the number of the bit including a specific value included in a second bit stream.
