Abstract
(EN)
A control unit (6) allows a vertical scan circuit (3) to cyclically select a given one-dimensional pixel line from among pixel lines (21 to 23) each time a predetermined H period has elapsed and controls a read circuit (5) and a horizontal scan circuit (4) so as to read pixel signals of an object exposed by the selected pixel line. The control unit (6) further controls a vertical movement unit (8) so that the scan speed S satisfies S=P/4H where P is the array pitch in the vertical direction of the pixel lines (21 to 23) and H is the H period.
(FR)
L'invention porte sur une unité de commande (6) permettant à un circuit de balayage vertical (3) de sélectionner de manière cyclique une ligne unidimensionnelle de pixels donnée parmi des lignes de pixels (21 à 23) à chaque fois qu'une période H prédéterminée s'est écoulée et de commander un circuit de lecture (5) et un circuit de balayage horizontal (4) de façon à lire les signaux de pixels d'un objet rendu visible par la ligne de pixels sélectionnée. L'unité de commande (6) commande en outre une unité de mouvement vertical (8) de telle sorte que la vitesse de balayage S satisfait à S = P/4H, où P est le pas du réseau dans la direction verticale des lignes de pixel (21 à 23) et H est la période H.

制御部6は、所定のH期間が経過する毎に、垂直走査回路3に画素列21~23の中から任意の1行の一次元画素列を循環的に選択させ、選択された画素列により露光された被写体の画素信号を読み出すように読出回路5及び水平走査回路4を制御する。また、制御部6は、画素列21~23の垂直方向の配列ピッチをP、H期間をHとすると、スキャン速度Sが、S=P/4Hを満たすように垂直移動部8を制御する。
