摘要： An image transmitting apparatus for digitizing a still-picture television signal, a manuscript image signal or the like and transmitting the digitized signal over a line is adapted to read an analog image signal stored in video memory such as a video disk, convert the read analog image signal into a digitized multi-valued signal and store the multi-valued image signal in an image memory. On the basis of paper size on which printing is to be performed by an apparatus, such as a facsimile machine, on the receiving side, the number of pixels constituting the multi-valued image signal stored in the image memory and an ensuing binary coding method, a ratio is obtained at which the multi-valued image signal stored in the image memory is to be expanded or compressed, and the multi-valued image signal is expanded or compressed based on this ratio. The multi-valued image signal thus expanded or compressed is binary coded as by a dither method, and the binary-coded image data are transmitted to the facsimile machine on the receiving side through a line.

摘要： A signal processing device detects information drop-out parts of an incoming information signal by dividing the information signal received for a given period of time into an n number (n: an integer which is at least 2) of blocks and by forming an information drop-out part signal indicating a part that has an information drop-out within each of the blocks. The device is thus arranged to be capable of promptly finding the parts of the information signal having information drop-outs.
