Net4Voice - New Technologies for voice-converting in barrier-free learning environment

A solid-state image sensor including pixels including photodetectors (111-148) for detecting light signals and charge sweep devices (210-240) for transferring signal charges. The pixels are arranged in first and second directions orthogonal to each other. A transfer gate scanning circuit (600) sequentially selects a pixel row from a plurality of pixel rows arranged in a second direction. A charge sweep device scanning circuit (700) supplies readout signals to the selected pixel rows so that signal charges may be read out, a plurality of times, within a horizontal scanning interval from the photodetectors (111-148).
