Abstract
A solid-state electronic image sensing device applicable to a digital camera includes signal lines for feeding transfer gate pulses to transfer gates. The signal lines on an “N+1”, an “N+5” and an “N+13” row are connected together while the signal lines on an “N+3”, an “N+7”, an “N+11” and an “N+15” row are connected together. Likewise, the signal lines on an “N+4”, an “N+8”, an “N+12” and an “N+14” row are connected together. Further, the signal lines on an “N+6”, an “N+10” and an “N+14” row are connected together. Six kinds of signal lines, i.e., the above signal lines and two independent signal lines on an “N+2” and an “N+9” row each are connected to a particular transfer gate via an electrode formed between one of photosensitive cells arranged in the row direction and associated one of vertical transfer paths. Vertical drive signals each are simultaneously fed to preselected signal lines in order to transfer signal charges from the photosensitive cells.
