The invention discloses a zoom type large-detection-area streak image converter tube and a camera, the zoom type large-detection-area streak image converter tube comprises a photoelectric cathode, a focusing system, a zoom electrode, an anode, a first scanning deflection system, a second scanning deflection system and a fluorescent screen, the zoom electrode is introduced into the streak image converter tube, so that streak image converter tube working modes with different amplification factors can be provided; the change of the magnification inevitably causes the change of the focal length of the electron optical system, and the cross point and the focus point of the streak image converter tube can be conveniently adjusted by combining the immersed electrostatic focusing lens, so that the streak image converter tube obtains higher spatial resolution and realizes different magnifications. According to the invention, high-precision ultrafast pulse optical signal diagnosis requirements in different fields and d
