Abstract:
1. A solid-state imaging device, comprising: a photodetecting section having M (an integer not less than 2)×N (an integer not less than 2) pixel portions P a plurality of reading-out wirings L a signal reading-out section being connected to each of the plurality of reading-out wirings L a plurality of row selecting wrings L a row selecting section having a plurality of first buffers which are respectively connected to one ends of the plurality of row selecting wirings L an overflow preventing section having a plurality of second buffers each of which corresponds to the associated one of the plurality of first buffers and which are respectively connected to the other ends of the plurality of row selecting wirings L a controlling section connected to the row selecting section, the overflow preventing section, and the signal reading-out section, wherein the plurality of first buffers are located on opposite side of the plurality of second buffers so that the plurality of first buffers sandwich the photodetecting section together with the plurality of second buffers, wherein the signal reading-out section includes a plurality of holding circuits H wherein in a time axis, the controlling section controls rise time and fall time of each of the row selecting controlling signal, the overflow preventing signal, and the hold controlling signal so that the rise time of the hold controlling signal shifts from both the rise time and fall time of each of the row selecting controlling signal and the overflow preventing signal and so that the fall time of the hold controlling signal shifts from both the rise time and fall time of each of the row selecting controlling signal and the overflow preventing signal.
