A teleconference terminal apparatus includes: imaging field changing control means for carrying out control of an imaging field changing unit designed to change the position of the imaging field of an imaging unit; preset information managing means; image signal transmitting means for outputting and transmitting an image signal to another teleconference terminal apparatus; still image generating means for generating still image information based on an image signal obtained by the imaging unit; and transmitted image control means for controlling the image signal transmitting means to transmit an image signal based on an image signal obtained by the imaging unit during a first period in which the imaging field changing control means does not carry out position changing control, and controlling the image signal transmitting means to transmit, during a second period in which the position changing control is carried out, an image signal based on still image information generated by the still image generating means when the second period is initiated.
