Zusammenfassung: | An image-capture apparatus includes a variable magnification lens, imaging means for converting an image taken by the variable magnification lens into an electrical image signal, and imaging control means. By referring to a conversion coordinate coefficient, the image control means moves a point on the image and outputs the new image signal. In the variable magnification lens, in order from the object side, a first lens group having positive refractive power, a second lens group that has negative refractive power and performs a variable magnification action by shifting on an optical axis, a third lens group having positive refractive power, a fourth lens group that has negative refractive power and a fifth lens group having positive refractive power are arrayed. |
