Abstract

To transmit and receive an instruction of superposing an image on a predetermined position on a display screen of a picked-up image and an instruction of superposing superposition information in the predetermined range of the picked-up image in accordance with a change in the picked-up image in a transmission and reception system including a single communication interface. A reception unit that receives a parameter from a setting apparatus and a superposition unit that selects a first superposition mode for superposing the superposition information on the predetermined position on the display screen of the picked-up image or a second superposition mode for superposing the superposition information on the position on the picked-up image in accordance with the change in the picked-up image in accordance with the received parameter for superposition of the superposition information.

10. The image transmission apparatus according to claim 1, wherein the first and second commands designate color of text for the first text information.

11. The image transmission apparatus according to claim 1, wherein the first and second commands designate whether text for the first text information is transparent.

12. The image transmission apparatus according to claim 1, wherein the first and second commands designate color of background for the first text information.

13. The image transmission apparatus according to claim 1, wherein the second command includes first parameter value which indicates that the first text information is superposed in accordance with the change.

14. The image transmission apparatus according to claim 13, wherein the first command includes a second parameter value which indicates that the first text information is superposed on the fixed position in the picked-up video image.

15. The image transmission apparatus according to claim 1, wherein the transmission unit transmits the superposed video image to the external apparatus.

16. A method for an image transmission apparatus, the method comprising:

receiving at least one of a first command and a second command from an external apparatus, wherein the first and second commands are commands to superpose first text information on a picked-up video image picked up by an image pickup unit; and

transmitting a superposed video image in which the first text information is superposed on the picked-up video image, when at least one of the first command and the second command is received,

wherein, when the first command is received, the superposed video image is a video image in which the first text information is always superposed on a fixed position in the picked-up video image, regardless of a change of at least one of a pan angle, a tilt angle, and a zoom magnification of the image pickup unit, and

wherein, when the second command is received, the superposed video image is a video image in which the first text information is superposed in accordance with the change of at least one of the pan angle, the tilt angle, and the zoom magnification.

17. A non-transitory computer-readable storage medium storing a program to cause an image transmission apparatus to perform a method, the method comprising:

receiving at least one of a first command and a second command from an external apparatus, wherein the first and second commands are commands to superpose first text information on a picked-up video image picked up by an image pickup unit; and
