<p>PROBLEM TO BE SOLVED: To provide a solid-state image pickup device for detecting motion that detects a mobile body based on a color component of an incident light with a simple configuration and high precision without the need for external image processing. SOLUTION: Green, red and blue group pixels 101G, 101R, 101B are arranged in a matrix to a light receiving section of a motion detection solid-state image pickup device 100 to detect each color component of the incident light. An electric signal from a pixel of a specific row is transferred to vertical read lines 102a,... for each column in a prescribed timing by a vertical scanning circuit 106 and further transferred to a horizontal read line 112 by a horizontal scanning circuit 113. Each of the vertical read line 192a,... is provided with a different value detection circuit 107 that stores an electric signal from the corresponding pixels 101R,... in a prescribed timing as an electric signal of a just preceding frame, compares the electric signal with an electric signal corresponding to a current frame outputted from the same pixels 101R,... in a succeeding prescribed timing and provides an output of a different value signal.</p> |
