As stated, Electrofax 100 replaces mechanical focal plane shutters and flat liquid crystal shutter 220 with focal plane formula.Therefore, need not be used for actuator that driving mechanism that the heavy curtain to focal plane shutter drives and shutter tighten usefulness or mechanism etc., simplify the structure of Electrofax 100, can realize small-sized, the lightweight of Electrofax 100.
Here, shutter means the light that shutter sees through when being in the shading state through light.When inciding the illumination of object light of liquid crystal shutter 220 when very big,, can not ignore and see through and arrive the influence of light of the sensitive surface of imaging apparatus 214 even liquid crystal shutter 220 is in the shading state through changing camera lens 320.For example, adopt at imaging apparatus 214 under the situation of mode of rolling shutters, accomplish and make shutter after liquid crystal shutter 220 is in the shading state see through the light quantity of light when big when a series of exposure actions, electric charge increases in the pixel of also not reading picture signal.About this point, when carrying out the exposure of global shutter mode, as following explanation; Because the electric charge through exposure actions originally obtains is preserved; Thereby after exposure actions is accomplished, even light arrives the photoelectric conversion part of the pixel before picture signal is read, also almost not influence.
The CCD (IT-CCD) of load mode in the ranks of type that is widely used in Electrofax when use can carry out the exposure of global shutter mode during as imaging apparatus 214.That is to say; In whole pixels, roughly do not need the discharge of electric charge simultaneously; After through the predetermined time for exposure; Be sent to the transmission passage together through the electric charge in the photoelectric conversion part that will be accumulated in each pixel, roughly accumulate the beginning of action simultaneously in can the whole pixels on imaging apparatus 214 and stop.Through using IT-CCD; The electric charge that in exposure actions originally, obtains is sent to when exposure actions is accomplished and transmits passage (vertical CCD); Thereby in the output action of picture signal; Even shutter sees through light and incides photoelectric conversion part and in photoelectric conversion part, produce electric charge, also almost not influence.
At imaging apparatus 214 is can carry out under the situation of cmos sensor of exposure of global shutter mode, constitutes in whole pixels, roughly to remove simultaneously to be present in the electric charge in photoelectric conversion part and the floating diffusion region territory.And, between the photoelectric conversion part of each pixel and floating diffusion region territory, be equipped with switch element, can be roughly these switch elements of on/off simultaneously.That is to say; Constitute; In whole pixels, roughly carry out the removing of above-mentioned electric charge simultaneously; After through the predetermined time for exposure, all roughly break off above-mentioned switch element simultaneously in the pixels, thereby roughly accumulating the beginning of action simultaneously in can the whole pixels on imaging apparatus and stop.Like this, be can carry out under the situation of cmos sensor of exposure of global shutter mode at imaging apparatus 214, the electric charge that in the photoelectric conversion part of each pixel, obtains through exposure actions originally is sent to the floating diffusion region territory of each pixel successively.Then, when exposure actions is accomplished, break off and be located at the switch element between photoelectric conversion part and the floating diffusion region territory, can make between photoelectric conversion part and the floating diffusion region territory to be in dissengaged positions.Therefore, even because shutter sees through light and in photoelectric conversion part, produces electric charge, this electric charge can not move to the floating diffusion region territory of not reading pixel yet, can the picture signal of being read be impacted hardly.
About the structure of the CMOS imaging apparatus of global shutter mode, for example in the applicant's TOHKEMY 2009-188650, carried out openly in detail, thereby omit its detailed description in this manual.
