Abstract
A solid-state image sensor device comprises an image sensor section for outputting analog signals of an image being taken; a plurality of AD converter sections, arranged with respect to the column direction of the image sensor section, for converting the analog signals into digital signals; a drive circuit section for controlling the image sensor section and the AD converter sections; and a plurality of differential interface sections for transmitting the digital signals converted by the AD converter sections as differential output signals to an external device. Each of the differential interface sections comprises a current value changeover circuit and offset voltage holding circuit operative when an operation mode changeover is made.
