Imaging apparatus 214 is described.In this execution mode, imaging apparatus 214 has the switch element that can carry out electrical control to the beginning and the end of exposure actions, can control exposure actions with the mode of so-called electronic shutter.At this moment, imaging apparatus 214 can make public with the mode line preface ground of rolling shutter, still, preferably makes public with the mode of global shutter.As the imaging apparatus 214 that can carry out exposure actions with the mode of global shutter, can be the CCD imaging apparatus, also can be the CMOS imaging apparatus.The reason of preferably making public with the mode of global shutter is that the influence that makes shutter see through light minimizes.
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, in the pixel of also not reading picture signal, electric charge increases.About this point, when carrying out the exposure of global shutter mode, as following explanation; The electric charge that preservation obtains through exposure actions originally, so, 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.Promptly; In whole pixels, roughly side by side carry out the discharge of unnecessary electric charge; After the time for exposure of having passed through regulation; The electric charge that in the photoelectric conversion part of each pixel, accumulate is sent to transfer channel together, thus, roughly side by side accumulates the beginning of action in can the whole pixels on imaging apparatus 214 and stops.Through using IT-CCD; The electric charge that obtains through exposure actions originally is sent to transmission passage (vertical CCD) when exposure actions is accomplished; So; In the output action of picture signal, incide photoelectric conversion part and in photoelectric conversion part, produce electric charge, also almost not influence even shutter sees through light.
At imaging apparatus 214 is can carry out under the situation of cmos sensor of exposure of global shutter mode, in whole pixels, can roughly side by side remove the electric charge that is present in photoelectric conversion part and the floating diffusion region.And, between the photoelectric conversion part of each pixel and floating diffusion region, set switch element, can be roughly these switch elements of on/off side by side.Promptly; In whole pixels, roughly side by side carry out the removing of above-mentioned electric charge, after the time for exposure of having passed through regulation, all roughly side by side break off above-mentioned switch element in the pixels; Thus, roughly side by side accumulate the beginning of action 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 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, can make between photoelectric conversion part and the floating diffusion region becomes dissengaged positions.Therefore, even, can the picture signal of being read be impacted hardly because shutter sees through light and in photoelectric conversion part, produces electric charge, and this electric charge can not move to the floating diffusion region of not reading pixel yet.
