SOLID STATE IMAGING DEVICE, IMAGING APPARATUS, AND IMAGING METHOD

To provide a solid state imaging device, an imaging apparatus, and an imaging method, capable of acquiring an image with an excellent gray scale.SOLUTION: A solid state imaging device comprises: a pixel array in which a plurality of pixels in which an optical sensor part emitting a pulse of a prescribed pulse width at a frequency in accordance with a light reception frequency of a light quantum is arranged in a matrix state; a counter counting the number of pulses emitted from the optical sensor part; and a control part capable of performing a control so that a count value is read out from the counter in a period smaller than the product of a counter upper limit value of the counter and a prescribed pulse width.SELECTED DRAWING: Figure 1 【課題】階調の良好な画像を取得し得る固体撮像素子、撮像装置及び撮像方法を提供する。【解決手段】光子の受光頻度に応じた頻度で所定のパルス幅のパルスを発する光センサ部が備えられた複数の画素が行列状に配された画素アレイと、光センサ部から発せられるパルスの数をカウントするカウンタと、カウンタのカウント上限値と所定のパルス幅との積以下の周期で、カウンタからのカウント値の読み出しが行われるように制御を行い得る制御部とを備えている。【選択図】図１
