<p><P>PROBLEM TO BE SOLVED: To enable information input by light, even when the external light is strong and when it is weak. <P>SOLUTION: Two or more kinds of optical sensor elements, in which light-receiving sensitivities are different, are arranged on a pixel region. For instance, a column in which a pixel 21 provided with the optical sensor element of low sensitivity is arranged, and a column, in which a pixel 22 provided with the optical sensor element of high sensitivity, is arranged are mutually arranged. With the constitution, when the external light is weak, light information input becomes possible by the optical sensor element of high sensitivity; and when it is strong, light information input is enabled by the optical sensor element of low sensitivity. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
