DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile transmitter, and more particularly, to a facsimile transmitter for automatically selecting the resolution of transmission image data according to a communication charge and transmitting the same.

[0002]

2. Description of the Related Art Conventionally, this type of facsimile transmitter has
For example, it was a technique described in Japanese Patent Application Laid-Open No. 4-256284. This publication discloses a facsimile machine having a resolution conversion unit for converting the resolution of a transmission image,
A charge calculation / comparison unit is provided for calculating a line charge for transmission image data for each resolution, and comparing the calculation results. When transmitting image data, a charge for each resolution is calculated and compared. In the case of a fee, an automatic resolution selection method for selecting a higher resolution for conversion and transmitting the resolution is described.

[0003]

In the above-described conventional facsimile transmitter, the image is converted and transmitted according to the image quality selected by the operator, so that the image quality is prioritized, and the transmission is performed without regard to the charge. . If the fee is restricted, there is a disadvantage that the only option is to select a coarse image quality and perform transmission.

The present invention has been made to solve the above-mentioned drawbacks of the prior art, and to automatically select and transmit an appropriate image quality at a desired call charge input by an operator as much as possible.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a document reading section for reading a document to be transmitted at the finest resolution, a memory section for storing read image information, and an operation input. An input operation unit for designating the other party's telephone number and the desired call charge, a call time calculation unit for calculating a talkable time from the data of the desired call charge, the other party's telephone number and the own telephone number, and the call time calculation An image quality selection unit that selects an appropriate image quality that can be transmitted within the callable time based on the callable time notified by the unit and the data amount of the image information stored in the memory unit, and is selected by the image quality selection unit. Image quality conversion unit for converting the image quality to
An encoding unit that encodes the image data input from the image quality conversion unit, a modem unit that modulates the encoded image data and makes a call to a line, and a main control unit that controls operations of these units. And inputting the telephone number of the other party and the desired call rate from the input operation section, and pressing a start button, the image quality transmitted within the desired call rate input by the operator is changed to the image quality. A facsimile transmitter that automatically selects the selection unit and automatically selects the minimum image quality in response to the inability to transmit within the desired call charge and transmits each automatically is used as the means.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention.

Reference numeral 1 denotes a document reading unit that reads and outputs the image information of the document at the finest resolution when transmitting the document, and 2 denotes a memory unit that stores the read image information and notifies the data amount of the image information. Reference numeral 3 denotes an input operation unit which designates a destination telephone number and a desired call charge by operation input, outputs the information, and has a start switch.
Reference numeral 4 denotes a main control unit for controlling the operation of each unit. This is a call time calculation unit that calculates and notifies a possible time. Reference numeral 6 denotes an image quality selection unit that selects and notifies an appropriate image quality that can be transmitted within the callable time based on the notified callable time and the data amount of the image information in the memory. Therefore, the image quality conversion unit converts and outputs image information in the memory. Reference numeral 8 denotes an encoding unit that encodes the converted image information. Reference numeral 9 denotes a circuit that modulates the encoded image information and calls the line.

Next, the operation of the facsimile transmitter of the present invention will be described with reference to the flowchart of FIG. Each processing in FIG. 2 is shown in parentheses.

Before performing the transmission operation, the telephone number of the own station is input to the call time calculation unit 5 from the input operation unit 3 and registered. Then, the original is set on the reading unit 1 (1
0), the other party's telephone number and desired call charge are input from the input operation section 3 (11, 12), and the start button is pressed (13). Then, the document reading unit 1 reads the document at the finest resolution (14) and stores it in the memory unit 2 (1).
5). Next, the call time calculation unit 5 calculates the telephone number data of the own station, the data of the other party's telephone number, and the data of the desired call charge.
Calculates the talkable time in (16). Next, the image quality selection unit 6 ends the transmission within the calculated talk time (17), and no image quality is OK in the calculated talk time (1).
8) In the case, an appropriate image quality is selected (19). However, if the transmission is not completed within the calculated callable time, the coarsest minimum image quality is selected (22), and if any image quality is OK within the calculateable time, the finest maximum image quality is selected. (21). Next, the image quality conversion unit 7 converts the image information stored in the memory unit 2 into the selected image quality (20), and starts communication via the encoding unit 8 and the modem unit 9 (23).

[0013]

As described above, according to the present invention, an appropriate image quality is automatically selected and transmitted within a desired call charge inputted by an operator, thereby placing importance on the desired charge of the operator. In addition, there is an effect that transmission can be performed at a resolution as fine as possible within the range.

Further, the present invention has an effect that if the transmission is not completed within the desired call charge input by the operator, the minimum image quality is selected and the charge is kept as low as possible.
