The invention discloses a device and a method for processing interlaced line-crossing stereoscopic composite video signals. The method comprises the following steps: firstly, finishing decoding interlaced crossing stereoscopic composite video signals in a 3D (three-dimensional) composite video decoder; then, converting the format of the composite video signals into the format of 16-bit YUV4:2:2; controlling the storage and read-out by an SDRAM (synchronous dynamic random access memory) frame memory; passing through two alternative multiplexers, so that the left-channel video is always outputted as an odd field and the right channel video is always outputted as an even field; and finally, outputting to an OLED (organic light emitting diode) micro-screen and displaying after image zooming and OSD (on-screen display) superposition. Upon the premise that only one 32-bit frame memory SDRAM is used, the invention can achieve the frame frequency elevation to the stereoscopic composite video signals and perform the f
