Abstract:
1. An image sensor comprising: a sensor unit having a plurality of pixels; a first scanning circuit for normal scanning, having a dynamic logic circuit for outputting one or more first selection signals for selecting pixels from among said plurality of pixels in said sensor unit; a second scanning circuit for use as an electric shutter having a dynamic logic circuit for outputting one or more second selection signals for selecting pixels from among said plurality of pixels in said sensor unit; and one or more selection circuits each configured to receive a first selection signal from among said one or more first selection signals and a second selection signal from among said one or more second selection signals each selection circuit comprising: wherein each selection circuit of said one or more selection circuits outputs the first AND signal and the second AND signal to said sensor unit, wherein each first bootstrap circuit includes: wherein each second bootstrap circuit includes: wherein said first boosting transistor in each first bootstrap circuit outputs the first AND signal from one of said drain and said source of said first boosting transistor by an input of the first drive signal to the other of said drain and said source of said first boosting transistor, wherein said second boosting transistor in each second bootstrap circuit outputs the second AND signal from one of said drain and said source of said second boosting transistor by an input of the second drive signal to the other of said drain and said source of said second boosting transistor, and wherein, in each selection circuit, said one of said drain and said source of said first boosting transistor is connected to said one of said drain and said source of said second boosting transistor to output the first AND signal and the second AND signal to said sensor unit.
