Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a drive unit capable of improving the image quality and increasing the speed of exposure time.SOLUTION: The drive unit includes an address decoder circuit provided to each pixel row of a pixel array in a solid state image sensor, which generates at least a control signal to control a pixel in the pixel row corresponding to a V address signal to perform a readout operation to read out an accumulated electric charge from the pixel or an electronic shutter operation to sweep the accumulated electric charge from the pixel based on the V address signal for identifying the pixel row in the pixel array. The address decoder circuit receives the V address signals from at least two different lines. At least two different address decoder circuits generate the control signals to at least two different pixel rows during one horizontal scanning period.
【課題】画質をより向上させるとともに撮影時間をより高速化することが可能とする。【解決手段】固体撮像素子内の画素アレイの各画素行に設けられ、当該画素アレイ中の画素行を特定するためのVアドレス信号に基づいて、当該Vアドレス信号に対応する画素行の画素に、当該画素から蓄積電荷を読み出す読み出し動作又は当該画素から蓄積電荷を掃き出す電子シャッタ動作を行わせるための制御信号を少なくとも生成するアドレスデコーダ回路、を備え、前記アドレスデコーダ回路には、少なくとも2つの互いに異なる系統の前記Vアドレス信号が供給され、1水平走査期間内に、少なくとも2つの互いに異なる前記アドレスデコーダ回路が、少なくとも2つの互いに異なる画素行に対して前記制御信号を生成する、駆動装置を提供する。【選択図】図7 |
