Abstract
An image sensor shutter module for use in an image sensor outputting image data with scanning line by line and a method for controlling the same are provided. The method for controlling a shutter for use in an image sensor includes: opening electronic shutters for every imaging line; opening mechanical shutter after all of the electronic shutters of every imaging line are opened; closing the mechanical shutter after a predetermined exposure time passes; and sequentially carrying out reading line image data of every imaging line with respect to each imaging line.
Claims26
A method for controlling a shutter for use in an image sensor, comprising:
- a) opening electronic shutters for every imaging line;
- b) opening a mechanical shutter after all of the electronic shutters of every imaging line are opened;
- c) closing the mechanical shutter after a predetermined exposure time passes;
- and
- d) sequentially carrying out reading line image data of every imaging line with respect to each imaging line.
An image sensor shutter module, comprising:
- an image sensor provided with a plurality of shutters for every imaging line to output an image data with scanning line by line;
- a mechanical shutter for physically blocking a light to the image sensor;
- and
- a shutter controller serving roles in determining an exposure time of the mechanical shutter according to an internal establishment or an external command, exposure points of the mechanical shutter as points after all of the electronic shutters of the image sensor are turned on, and turn-off points of the electronic shutters as points after the mechanical shutter is blocked.
