Abstract

An image processing apparatus determines, when image data of an image read from an original is transmitted to an external unit, whether the transmission is by a first communication method or a second communication method, and controls so that, based on a result of the determination, a transmission interval between a plurality of packets for when the image data is transmitted is longer when the image data is transmitted by the first communication method than when the image data is transmitted by the second communication method.

First claim

What is claimed is:

1. A communication apparatus comprising:
a generating unit configured to generate a packet including image data; and
a transmission unit configured to perform a first transmission method for transmitting the packet generated by the generating unit using a predetermined coding method, and to perform a second transmission method for transmitting the packet generated by the generating unit without using the predetermined coding method,
wherein the transmission unit transmits, in the first transmission method, a plurality of packets based on a waiting time between completion of transmission of a packet and start of transmission of a next packet, the waiting time being a period when a packet is not transmitted by the transmission unit,
wherein the transmission unit transmits, in the second transmission method, a plurality of packets not based on the waiting time, and
wherein at least one of the generating unit and the transmission unit is implemented by a processor and a memory.

2. The communication apparatus according to claim 1 , wherein the transmission unit transmits, in the first transmission method, a packet, and then transmits a next packet after the waiting time has been elapsed.

3. The communication apparatus according to claim 2 , wherein the transmission unit transmits, in the second transmission method, a packet, and then transmits a next packet without waiting until the waiting time elapses.

4. The communication apparatus according to claim 1 , further comprising
a verifying unit configured to verify, in the first transmission method, content of the image data; and
a changing unit configured to change, based on a verification result by the verifying unit, a data quantity for one packet
wherein at least one of the verifying unit and the changing unit is implemented by a processor and a memory.

5. The communication apparatus according to claim 4 , wherein
the verifying unit verifies a ratio of a predetermined value in the image data, and
wherein the communication apparatus further comprising
a setting unit configured to set, if the ratio is greater than or equal to a predetermined threshold, the data quantity for one packet to be a first data quantity, and to set, if the ratio is less than the predetermined threshold, the data quantity for one packet to be a second data quantity less than the first data quantity,
wherein the setting unit is implemented by a processor and a memory.

6. The communication apparatus according to claim 1 , further comprising
a verifying unit configured to verify, in the first transmission method, content of the image data, wherein
the transmission unit, based on a result of the verification of the verifying unit, changes the waiting time,
wherein the verifying unit is implemented by a processor and a memory.

7. The communication apparatus according to claim 6 , wherein the predetermined coding method is a Manchester encoding method.

8. The communication apparatus according to claim 1 , wherein the first transmission method is 10BASE-T, and the second transmission method is 100BASE-TX.

9. The communication apparatus according to claim 1 , further comprising
a reading unit configured to read an image from an original, and generate the image data.

10. The communication apparatus according to claim 1 , wherein image data is raw data.

11. A method of controlling a communication apparatus comprising:
generating a packet including image data; and
performing a first transmission method for transmitting the generated packet using a predetermined coding method, and to perform a second transmission method for transmitting the generated packet without using the predetermined coding method,
wherein a plurality of packets are transmitted based on a waiting time between completion of transmission of a packet and start of transmission of a next packet the first transmission method, the waiting time being a period when a packet is not transmitted by the transmission unit, and
wherein a plurality of packets are transmitted not based on the waiting time in the second transmission method.

12. A non-transitory computer-readable storage medium storing a computer program for controlling a communication apparatus, the computer program comprising:
a code to generate a packet including image data; and
a code to perform a first transmission method for transmitting the generated packet using a predetermined coding method, and to perform a second transmission method for transmitting the generated packet without using the predetermined coding method, and
wherein a plurality of packets are transmitted based on a waiting time between completion of transmission of a packet and start of transmission of a next packet in the first transmission method, the waiting time being a period when a packet is not transmitted by the transmission unit, and
wherein a plurality of packets are transmitted not based on the waiting time in the second transmission method.
