Abstract

PURPOSE:To attain efficient transmission even if a character part is partially superposed on an image part in an original picture by adding respectively inherent headers to a character code and picture element data and transmitting them. CONSTITUTION:An original picture 4 is scanned by a transmission scanning part 6 and converted into an electric signal corresponding to the density of the original picture 4 by a photoelectric conversion part 7. Whether the output of the conversion part 7 is a character or an image is decided by a deciding part 8, the character is read out by a character reader 9 and the read result is encoded by a character code generating part 10. When the decided result is an image, the image is processed as a signal by an image signal processing part 11 and sent to a transmission part 12. The transmission part 12 adds headers respectively inherent in the character code and the picture element data to the code and the data and transmits the added contents. Even if the character part is partially superposed on the image part, the character part and the image part can be efficiently transmitted respectively as the character code and the image data.

(Description of Prior Art) Conventionally, this type of device, when transmitting the original image, attaches a special mark to the original image to indicate that it is a character area (or image area), or stores a format in advance. It was then converted into character code or pixel data. In any case, the case where text and images overlap was not taken into account.

(Object of the Invention) The present invention eliminates the drawbacks of the conventional example described above. In a facsimile machine having a character reading function, the character part in the original image that overlaps with the image part is a character code, and the character part that overlaps with the character part is a character code. The image part is pixel data or its compressed data, and the facsimile machine has a character reading function characterized by having means for transmitting each image with a character or pixel header. This eliminates the need for adding distinguishing marks or storing formats in the storage unit.

FIG. 2 is a diagram showing an embodiment of the transmitting side of the apparatus of the present invention. The original image 4 is scanned by a transmission scanning section 6 driven by the control of the scan control section 5, and converted by a photoelectric conversion section 7 into an electrical signal corresponding to the shading of the original image 4. Photoelectric conversion section 7
The output of is fed to the determination section 8. Here, it is determined whether it is a character or an image, the character is read by a character reader 9, the result is coded by a character code generator 10, and the image is processed by an image signal processor 11, which is similar to conventional facsimile. The signal is processed by the rod and sent to the transmitter 12 at the next stage. The transmitter 12 adds unique headers to the character code and pixel data and transmits them.

.. 16 is a comparator. If text and image signals are mixed in the same area of the signals from the photoelectric conversion unit 7h), for example, the text signal will be a high-level component, the photographic image will be a low-level component, and a certain Those with a threshold value of 8 or higher are letters,
Images below the threshold value are judged simultaneously. a and b may be the same. Therefore, even if there are overlapping areas, characters and photographic images can be separated.

The present invention is not limited to the above-described embodiments, and can be modified in various ways without changing the gist thereof. For example, by storing a certain line of output from the photoelectric conversion unit 7, which determines whether it is a character or an image by simple threshold processing,
This may also be done by utilizing its statistical properties. The statistical property for flJ refers to, for example, looking at the histogram of the output signal in step 7, and if it is polarized, it is determined to be a character signal, and if the signal values are dispersed, it is determined to be an image signal. FIG. 5 shows an embodiment for this purpose, in which the storage section 30 stores 7 for appropriate lines.
The output is stored, separated into characters or images by the statistical property processing section 31, and sent to the character reader 91 and image signal processing section 11, respectively.
