A picture number of an image to be displayed on a liquid crystal display is compared with index data contained in an index section of a work memory to produce a display signal to be delivered to the liquid crystal display by using compressed or non-compressed data which has been left in a data section of the work memory when it is determined that the compared data coincided with each other. In this condition, both of a procedure for reading out the compressed data from an image recording section and a procedure for expanding the compressed data become unnecessary in case of utilizing non-compressed data, while only a procedure for reading the compressed data from the image recording section becomes unnecessary, though a procedure for expanding the compressed data is required in case of utilizing compressed data, so that it becomes possible to remarkably increase a speed in a procedure configured to display image, whereby instantaneous reproduction of image can be improved in either cases of compressed or non-compressed data.
