1. An image processing apparatus which is connected to a camera head capable of imaging a left eye image and a right eye image having parallax on one screen based on light at a target site incident on an optical instrument, the apparatus comprising:
an image processor that performs signal processing to extract left parallax video of the left eye image and to extract right parallax video of the right eye image, which are imaged by the camera head; and
an output controller that outputs the left parallax video of the left eye image to a monitor via a first channel, and that outputs the right parallax video of the right eye image to the monitor via a second channel, in accordance with a 3D mode,
wherein the output controller outputs one of either the left parallax video of the left eye image or the right parallax video of the right eye image to the monitor via both of the first channel and the second channel, in accordance with switching from the 3D mode to a 2D mode,
wherein the image processor maintains a transmission format of the other of either the left parallax video of the left eye image or the right parallax video of the right eye image, in accordance with the switching from the 3D mode to the 2D mode, and
wherein the output controller displays the 2D video on the monitor in a pseudo manner in a 2D mode based on one of the left eye image and the right eye image output to the monitor via the first channel and the second channel.
2. The image processing apparatus of claim 1 ,
wherein the switching from the 3D mode to the 2D mode is input by a user operation.
3. The image processing apparatus of claim 1 , further comprising:
a distance measurer that measures a distance from the optical instrument to the target site based on the parallax appearing in the left eye image and the right eye image which are imaged by the camera head in the 3D mode,
wherein the output controller outputs the information on the distance to the monitor together with the left eye image and the right eye image on which the signal processing is performed.
4. The image processing apparatus of claim 3 ,
wherein the output controller interrupts an output of the information on the distance to the monitor in response to switching from the 3D mode to the 2D mode.
5. A camera apparatus comprising:
a camera head capable of imaging a left eye image and a right eye image having parallax on one screen based on light at a target site incident on an optical instrument;
an image processor that performs signal processing to extract left parallax video of the left eye image and to extract right parallax video of the right eye image, which are imaged by the camera head; and
an output controller that outputs the left parallax video of the left eye image to a monitor via a first channel, and that outputs the right parallax video of the right eye image to the monitor via a second channel, in accordance with a 3D mode,
wherein the output controller outputs one of either the left parallax video of the left eye image or the right parallax video of the right eye image to the monitor via both of the first channel and the second channel, in accordance with switching from the 3D mode to a 2D mode,
wherein the image processor maintains a transmission format of the other of either the left parallax video of the left eye image or the right parallax video of the right eye image, in accordance with the switching from the 3D mode to the 2D mode, and
wherein the output controller displays the 2D video on the monitor in a pseudo manner in a 2D mode based on one of the left eye image and the right eye image output to the monitor via the first channel and the second channel.
6. An output control method in which an image processing apparatus which is connected to a camera head capable of imaging a left eye image and a right eye image having parallax on one screen based on light at a target site incident on an optical instrument is used, the method comprising:
performing signal processing to extract left parallax video of the left eye image and to extract right parallax video of the right eye image, which are imaged by the camera head; and
outputting the left parallax video of the left eye image to a monitor via a first channel and outputting the right parallax video of the right eye image to the monitor via a second channel, in accordance with a 3D mode; and
outputting one of either the left parallax video of the left eye image or the right parallax video of the right eye image the monitor via both of the first channel and the second channel, in accordance with switching from the 3D mode to a 2D mode,
maintaining a transmission format of the other of either the left parallax video of the left eye image or the right parallax video of the right eye image, in accordance with the switching from the 3D mode to the 2D mode, and
wherein the output controller displays the 2D video on the monitor in a pseudo manner in a 2D mode based on one of the left eye image and the right eye image output to the monitor via the first channel and the second channel.
