Title
(EN) IMAGE ACQUISITION METHOD FOR TFT FLAT PANEL IMAGE SENSOR
(FR) PROCÉDÉ D'ACQUISITION D'IMAGE POUR CAPTEUR D'IMAGE À ÉCRAN PLAT TFT
(ZH) TFT平板图像传感器的图像采集方法
Abstract
(EN)
An image acquisition method for a TFT flat panel image sensor. The image acquisition method comprises: setting one signal acquisition period of a signal readout chip as a first cycle; setting a time for completing one driving operation on a scan line as a driving time; setting the length of the first cycle to be equal to that of the driving time; setting an ending time point of the mth first cycle to overlap a starting time point of the (m+1)th first cycle, wherein m is a positive integer; and setting an ending time point of the nth driving time to overlap a starting time point of the (n+1)th driving time, wherein n is a positive integer. By means of the image acquisition method, the stability of a signal readout chip is improved, and the design difficulty of an entire circuit system is reduced.

L'invention concerne un procédé d'acquisition d'image pour un capteur d'image à écran plat TFT. Le procédé d'acquisition d'image consiste : à établir une période d'acquisition de signal d'une puce de lecture de signal en tant que premier cycle ; à établir un laps de temps pour achever une opération de commande sur une ligne de balayage en tant que temps de commande ; à établir la longueur du premier cycle comme devant être égale à celle du temps de commande ; à établir un point temporel de fin du mièmepremier cycle afin de chevaucher un point temporel de départ du (m+1)ième premier cycle, m étant un entier positif ; à établir un point temporel de fin du nième temps de commande afin de chevaucher un point temporel de départ du (n+1)ième temps de commande, n étant un entier positif. Au moyen du procédé d'acquisition d'image, la stabilité d'une puce de lecture de signal est améliorée, et la difficulté de conception d'un système de circuit entier est réduite.
