Amplifier type image sensor with shutter operation

Masaharu Hamasaki
TLDR
In this paper, the authors present a solid state image sensor with an electronic shutter function, which includes a means for resetting a horizontal line spaced apart from a vertical line currently read out in the vertical scanning direction.
Abstract: 
The present invention is directed to a solid state image sensor in which one horizontal line from an image sensor section is selected as a line in which a signal is read out from a pixel, a signal is read out to a vertical signal line by a vertical scanning in which selected horizontal lines are sequentially switched, and pixel the signal of the horizontal line, processed in a correlation double sampling fashion, is read out to a horizontal signal line in a constant order. This solid state image sensor has an electronic shutter function includes an electronic shutter scanning means for resetting a horizontal line spaced apart from a horizontal line currently read out by a shutter time in the vertical scanning direction.

Solid-state image pickup device

Suzuki Masahito, +3 more
TL;DR: In this paper, the authors proposed to pickup a moving substance without using a special light source such as a stroboscope and a mechanical shutter mechanism by overlapping another pulse to the signal used to transfer the charge signal generated at the photo-detecting part to the accumulating part.

Photoconversion device having reset control circuitry

Seiji Hashimoto, +1 more
TL;DR: In this article, a photoconversion device is read out by providing a positive pulse to the base of the sensor T through the control electrode, and is refreshed by a first operation in which the base is set to a preset level through the reset switch FET M and a second operation where the base-emitter junction of sensor T is forward biased.
