Abstract
In memory storage transmission, if image transmission has been interrupted because of an error, the cause of the error is determined. Error image data whose retransmission has a possibility of success is preserved in an image memory, and error image data whose retransmission has no possibility of success is erased from the image memory. If error image data is preserved in the image memory, and storage of new image data in the image memory is instructed, error image data preserved in the image memory is erased in accordance with the remaining amount of memory capacity of the image memory. It is thereby possible to preserve appropriate error image data in the image memory without reducing the efficiency of the memory.
Claims19
A facsimile apparatus, comprising:
- data storage means for storing image data;
- transmission means for transmitting the image data stored in said data storage means;
- and
- control means for determining whether image transmission by said transmission means has ended normally or was interrupted because of an error, determining a cause of the error when the image transmission was interrupted because of the error, and selectively erasing or preserving the image data in said data storage means according to a result of these determinations.
A facsimile apparatus, comprising:
- data storage means for storing image data;
- manual instruction means for instructing storage of the image data in said data storage means;
- transmission means for transmitting the image data stored in said data storage means;
- and
- control means for determining whether the image transmission by said transmission means has ended normally or was interrupted because of an error, selectively erasing or preserving the image data stored in said data storage means according to a result of the determination, and selectively erasing image data whose image transmission was interrupted because of an error and which was preserved in said data storage means in response to an instruction to store new image data by said manual instruction means.
A facsimile apparatus, comprising:
- data storage means for storing image data;
- manual instruction means for instructing storage of the image data in said data storage means;
- transmission means for transmitting the image data stored in said data storage means;
- and
- control means for determining whether image transmission by said transmission means has ended normally or was interrupted because of an error, determining a cause of the error when the image transmission was interrupted because of the error, selectively erasing or preserving image data in said data storage means according to a result of these determinations, and selectively erasing image data whose image transmission was interrupted because of error and which was preserved in said data storage means in response to an instruction to store new image data by said manual instruction means.
A facsimile transmission method for storing image data in data storage means and transmitting the stored image data, said method comprising the steps of:
- determining whether the transmission of the image data stored in data storage means has ended normally, or was interrupted because of an error;
- determining a cause of the error when the transmission was interrupted because of the error;
- and
- erasing the image data stored in the data storage means when the transmission has ended normally and also when it determines that there is no possibility of retransmission according to the cause of the error, and preserving the image data in the data storage means when it determines that there is a possibility of retransmission according to the cause of the error.
A facsimile transmission method for storing image data in data storage means and transmitting the stored image data, said method comprising the steps of:
- erasing image data stored in data storage means when transmission of the image data has ended normally, and preserving the image data stored in the data storage means when the transmission of the image data was interrupted because of an error;
- and
- selectively erasing image data whose transmission was interrupted because of an error and is stored in the data storage means in accordance with a remaining amount of data which can be stored in the data storage means when storage of new image data in the data storage means has been instructed.
