An apparatus for displaying a plurality of compressed images is disclosed, in which a high quality freeze display is made possible with a high vertical resolution and a multiplicity of compressed images can be displayed at the same time on the display screen without increasing the circuit scale extremely. Different video signals are processed for image compression in a plurality of processing circuits (1 to 4, 51 to 54), and a synthesized image is supplied to a display unit for displaying four compressed images on the display screen at the same time. In the case of an image sequence display, the image size is compressed into one half in horizontal and vertical directions respectively by the processing circuits, and the odd and even fields are separately written in field memories (21, 22). Also, in the case of freeze display, all the lines are written alternately in the field memories (21, 22) without compressing them vertically by a filter circuit (10). In either display mode, the data are read at high speed from the field memory (21) for odd fields, and from the field memory (22) for even fields. <IMAGE> |
