Abstract

A communication apparatus includes a conversion unit configured to convert data, an estimation unit configured to estimate a size after conversion of the data by the conversion unit before the conversion unit converts the data, and a notification unit configured to notify another communication apparatus of the size estimated by the estimation unit.

First claim

What is claimed is:

1 . A communication apparatus comprising:
a conversion unit configured to convert data; a first estimation unit configured to estimate, before the conversion unit converts the data, a size of the data after being converted by the conversion unit; a notification unit configured to notify another communication apparatus of the size estimated by the first estimation unit; a transmission unit configured to transmit the data converted by the conversion unit to said another communication apparatus; and a control unit configured to control, according to a response to the notification by the notification unit, whether to transmit the data converted by the conversion unit to said another communication apparatus.

2 . The communication apparatus according to claim 1 , wherein before the conversion unit converts the data, the notification unit notifies said another communication apparatus of the size estimated by the first estimation unit.

3 . The communication apparatus according to claim 1 , wherein the conversion unit converts the data so as to reduce a size of the data.

4 . The communication apparatus according to claim 1 , further comprising a determination unit configured to determine a transfer instruction of the data issued by a user,
wherein in a case where the determination unit determines the transfer instruction of the data, the first estimation unit estimates the size of the data after being converted.

5 . The communication apparatus according to claim 1 , wherein the data is data of a moving image captured by an image capture unit, and
wherein the conversion unit converts a bit rate of the data.

6 . The communication apparatus according to claim 5 , wherein the first estimation unit estimates the size of the data after being converted, based on at least a bit rate of the data after being converted by the conversion unit and a reproduction time of the data.

7 . The communication apparatus according to claim 1 , wherein the data is data of an image captured by an image capture unit, and
wherein the conversion unit converts a resolution of the data.

8 . The communication apparatus according to claim 1 , wherein the data is data of a still image captured by an image capture unit.

9 . The communication apparatus according to claim 1 , further comprising a reception unit configured to receive from said another communication apparatus information indicating whether to allow transfer of the data, as a response to the notification by the notification unit,
wherein the conversion unit converts the data in a case where the reception unit receives information indicating that the transfer of the data is allowed.

10 . The communication apparatus according to claim 9 , wherein the conversion unit does not convert the data in a case where the reception unit receives information indicating that the transfer of the data is not allowed.

11 . The communication apparatus according to claim 9 , wherein the reception unit receives the information indicating that the transfer of the data is allowed, in a case where said another communication apparatus has a memory area for storing the data converted by the conversion unit, and
wherein the reception unit receives information indicating that the transfer of the data is not allowed, in a case where said another communication apparatus does not have the memory area for storing the data converted by the conversion unit.

12 . The communication apparatus according to claim 9 , further comprising a change unit configured to change, in a case where the reception unit receives information indicating that the transfer of the data is not allowed, a conversion quality of the data after being converted by the conversion unit to other conversion quality; and
a second estimation unit configured to estimate a size of the data after being converted based on the other conversion quality.

13 . A method for controlling a communication apparatus, the method comprising:
converting data; estimating, before the data is converted, a size of the data after being converted; notifying another communication apparatus of the estimated size; transmitting the converted data to said another communication apparatus; and controlling, according to a response to the notification, whether to transmit the converted data to said another communication apparatus.

14 . A non-transitory computer-readable storage medium for storing a program that causes a computer to perform a method for controlling a communication apparatus, the method comprising:
converting data; estimating, before the data is converted, a size of the data after being converted; notifying another communication apparatus of the estimated size; transmitting the converted data to said another communication apparatus; and controlling, according to a response to the notification, whether to transmit the converted data to said another communication apparatus.
