Abstract:
In a solid-state image pickup device, each pixel at a selected row outputs to a corresponding column signal line a first analog signal in accordance with an amount of electric charges at an electric charge accumulation section in an initial state and a second analog signal in accordance with an amount of photoelectric charges transferred to the electric charge accumulation section. An A/D converter provided at each column performs A/D conversion on the first and second analog signals to output first and second digital signals, respectively. Of first to third latch circuits provided at each column, the first latch circuit takes in and holds the first digital signal outputted from the A/D converter. The second latch circuit takes in and holds the first digital signal held at the first latch circuit. The third latch circuit takes in and holds the second digital signal outputted from the A/D converter.
