Abstract

An image capture apparatus includes an image capture unit, a communication unit, and a control unit which communicates with an external device by first or second communication systems. The first system maintains communication connection even if the apparatus and device are not in a predetermined operational mode for executing image transmission processing. The second system maintains communication connection if the apparatus and device are in the predetermined mode. The control unit can automatically transmit a photographed image to an external device through the communication unit by the second communication system, and switch and control first and second functional modes for enabling and disabling a photography function, respectively. Where an image is photographed in the first mode, the control unit records the image as a target for automatic transmission. If the transmission target image is recorded, automatic transmission is not started during the first mode, and started during the second mode.

in a case in which an image is photographed in the first functional mode, record the photographed image as a transmission target image that is targeted for the automatic transmission; and

even if the transmission target image is recorded, control the communication unit not to start automatic transmission of the transmission target image to the external device during the first functional mode, and control the communication unit to start automatic transmission of the transmission target image to the external device during the second functional mode.

2. The image capture apparatus according to claim 1, wherein the control unit is further configured to:

switch and control a first power mode that is a power mode capable of enabling the photography function, and a second power mode that is a power mode capable of enabling the photography function, and disabling the communication function in relation to image transmission;

perform transition to the second power mode, in a case in which a predetermined period of time has elapsed without any user operation, or in a case in which a user instructs transition to a low power consumption mode, during the first power mode; and

perform transition to the second functional mode, in a case in which a predetermined period of time has elapsed without any user operation, or in a case in which a user instructs transition to the low power consumption mode, during the first functional mode.

3. The image capture apparatus according to claim 2, wherein the control unit is further configured to:

control the communication unit to start automatic transmission of the transmission target image to the external device, in a case in which a predetermined period of time has elapsed without any user operation, or in a case in which the user instructs transition to the low power consumption mode, and further, in a case in which automatic transmission is enabled, and an unsent image remains.

4. The image capture apparatus according to claim 2, wherein the control unit is further configured to:

perform transition to the first power mode and the first functional mode, in a case in which a user operation is received in the second functional mode and the second power mode.

5. The image capture apparatus according to claim 3, wherein the control unit is further configured to:

control the communication unit to suspend the automatic transmission to the external device, even if an unsent transmission target image remains, in a case in which the second functional mode transitions to the first functional mode, while the communication unit is transmitting the transmission target image to the external device.

6. The image capture apparatus according to claim 2, wherein the control unit is further configured to:

switch and control a third power mode that is a power mode for disabling both of the photography function and the communication function in relation to image transmission, in addition to the first power mode and the second power mode; and

in a case in which a predetermined period of time has elapsed without any user operation, or in a case in which the user instructs transition to the low power consumption mode, perform transition to the second power mode when the communication unit starts automatic transmission of the transmission target image to the external device, and perform transition to the third power mode when the communication unit does not start automatic transmission of the transmission target image to the external device.

7. The image capture apparatus according to claim 6, wherein the communication unit is configured to be able to:

communicate via a first communication system that allows for predetermined communication other than image transmission in the third power mode; and
