The invention relates to the technical fields of image acquisition and monitoring, in particular to a super-picture view finder and a view-finding method. The viewfinder comprises a shell, adjusting rods and mirrors. In the method, the central symmetric axis of the lens of image acquisition equipment is taken as an x axis; a first adjusting rod and a second adjusting rod are positioned at center points of lenses, the center points of the lenses are on the same vertical line, and the vertical line is taken as a y axis; the distance between the front end of the lens and an imaging chip is set as a, the height of the imaging chip is set as b, the total length of the equipment for external dimension is set as c, and the total height of the equipment for the external dimension is set as d; when the needed view-finding object is projected onto the upper lens via a lower lens, the distance between the first adjusting rod and the original point of the coordinate axes satisfies an expression shown in the specification, the included angle gamma between the front face of an upper lens and the x axis satisfies an expression shown in the specification, and the position of the lower lens and an included angle are adjusted according to different areas; when the needed view-finding object is projected onto the lower lens via the upper lens, the situation is symmetrically opposite to the first situation; and finally positions at which objects beyond the view-finding range of the image acquisition equipment are located are fully covered.
