Image capture apparatus and method for controlling the same

1. An image capture apparatus comprising:

an image capture unit;

a processor; and

a memory storing program which, when executed by the processor, causes the image capture apparatus to:

perform control to display, on a display unit, a live view image that is based on an image acquired by the image capture unit;

record, in a recording medium, image data that is based on the acquired image;

acquire additional information associated with a predetermined subject appearing in the live view image by reading the predetermined subject appearing in the live view image; and

perform control to superimpose the acquired additional information on the live view image and display the live view image with the superimposed acquired additional information on the display unit before the image data is recorded in the recording medium;

store the acquired additional information in a memory; and

delete the acquired additional information from the memory when a power source is turned off,

wherein the acquired additional information that is read out from the memory is superimposed on the live view image and the live view image is displayed with the superimposed acquired additional information on the display unit, and

wherein the image data and the acquired additional information are recorded in the recording medium in association with each other.

2. The apparatus according to claim 1 ,

wherein the program when executed by the processor further causes the apparatus to store the acquired additional information in a memory,

wherein the acquired additional information that is read out from the memory is superimposed on the live view image, and the live view image is displayed with the superimposed acquired additional information on the display unit, and

wherein the acquired additional information is stored in the memory after a power source is turned off.

3. The apparatus according to claim 2 , wherein, in a case where the acquired additional information is stored in the memory when the power source is turned on, the acquired additional information is displayed on the display unit.

4. The apparatus according to claim 1 , wherein, in a case where an instruction to start image capturing is issued, the acquired additional information that is displayed is hidden.

5. The apparatus according to claim 4 , wherein the image capturing is started in response to detecting half-pressing of a shutter button.

6. The apparatus according to claim 1 , wherein the image data that is based on the image acquired by the image capture unit is recorded in response to accepting a recording instruction and the additional information associated with the predetermined subject included in the live view image that is based on the image acquired by the image capture unit before accepting the recording instruction, in the recording medium in association with each other.

7. The apparatus according to claim 6 , wherein the recording instruction is accepted in response to detecting full-pressing of a shutter button.

8. The apparatus according to claim 1 , wherein, in a case where the acquired additional information is acquired again, a position at which the acquired additional information is displayed is changed.

9. The apparatus according to claim 1 , further

wherein a result of reading the predetermined subject appearing in the live view image is a code data,

wherein the additional information associated with the predetermined subject appearing in the live view image is acquired by searching a database based on the code data, and

wherein the program when executed by the processor further causes the apparatus to register pieces of additional information each associated with a code data in a database.

10. The apparatus according to claim 9 , wherein the program when executed by the processor further causes the apparatus to, in a case where the additional information associated with the code data is not registered in the database, perform a notification indicating that the additional information is not registered.

11. The apparatus according to claim 9 , wherein the image data is not recorded in the recording medium, in a case where the additional information associated with the code data is not registered in the database.

12. The apparatus according to claim 1 , wherein the predetermined subject is at least a one-dimensional barcode, a two-dimensional barcode, a numerical value, a letter, or a figure.

13. The apparatus according to claim 1 , wherein the image data recorded in the recording medium does not include the predetermined subject.

14. The apparatus according to claim 1 , wherein the additional information is acquired by analyzing the live view image in which the predetermined subject is appearing.

15. The apparatus according to claim 1 , wherein the additional information is character data indicated by the read predetermined subject.

16. A method of controlling an image capture apparatus, the method comprising:

performing control to display, on a display unit, a live view image that is based on an image acquired by an image capture unit;

recording, in a recording medium, image data that is based on the acquired image;

acquiring additional information associated with a predetermined subject appearing in the live view image by reading the predetermined subject appearing in the live view image;

performing control to superimpose the acquired additional information on the live view image; and

displaying the live view image with the superimposed acquired additional information on the display unit before the image data is recorded in the recording medium;

storing the acquired additional information in a memory; and

deleting the acquired additional information from the memory when a power source is turned off,

wherein the acquired additional information that is read out from the memory is superimposed on the live view image and the live view image is displayed with the superimposed acquired additional information on the display unit, and

wherein the image data and the acquired additional information are recorded in the recording medium in association with each other.

17. A non-transitory computer-readable storage medium storing a program that, when executed by a processor, causes the processor to perform operations comprising:

performing control to display, on a display unit, a live view image that is based on an acquired image by an image capturing unit;

recording, in a recording medium, image data that is based on the acquired image;

acquiring additional information associated with a predetermined subject appearing in the live view image by reading the predetermined subject appearing in the live view image;

performing control to superimpose the acquired additional information on the live view image; and

displaying the live view image with the superimposed acquired additional information on the display unit before the image data is recorded in the recording medium;

storing the acquired additional information in a memory; and

deleting the acquired additional information from the memory when a power source is turned off,

wherein the acquired additional information that is read out from the memory is superimposed on the live view image and the live view image is displayed with the superimposed acquired additional information on the display unit, and

wherein the image data and the acquired additional information are recorded in the recording medium in association with each other.
