Abstract

A projector comprises: a projector main frame having a memory for storing an image in form of data and a projection lens for projecting the image, in which the image stored in the memory is read and visualized, so that the visualized image is projected via the projection lens onto a screen; and a remote controller for performing a remote control of the projector main frame. The projector main frame has a remote controller mounting section for detachably mounting the remote controller at a position that the mounted remote controller covers the front of the projection lens of the projector main frame.

Claims (27)

1. A projector comprising: a projector main frame having a memory for storing an image in form of data and a projection lens for projecting the image, in which the image stored in the memory is read and visualized, so that the visualized image is projected via the projection lens onto a screen; and a remote controller for performing a remote control of the projector main frame,

wherein the projector main frame has a remote controller mounting section for detachably mounting the remote controller at a position that the mounted remote controller covers the front of the projection lens of the projector main frame, and

wherein the projector has a power source control section in which when the remote controller is mounted on the remote controller mounting section, a power supply to the projector main frame is turned off.

2. A projector comprising: a projector main frame having a memory for storing an image in form of data and a projection lens for projecting the image, in which the image stored in the memory is read and visualized, so that the visualized image is projected via the projection lens onto a screen; and a remote controller for performing a remote control of the projector main frame,

wherein the projector main frame has a remote controller mounting section for detachably mounting the remote controller at a position that the mounted remote controller covers the front of the projection lens of the projector main frame,

wherein the remote controller has a medium drive in which a portable storage medium storing an image is detachably mounted and is accessed, and a transmission section wherein in a state that the remote controller is removed from the remote controller mounting section, an image read from the portable storage medium mounted on the medium drive is transmitted to the projector main frame, and

wherein the projector main frame has a receiving section for receiving the image transmitted from the remote controller to store the image in the memory.

3. A projector according to claim 2 , wherein the remote controller has an imaging device, and the transmission section transmits an image imaged by the imaging device to the projector main frame.

4. A projector comprising: a projector main frame having a memory for storing an image in form of data and a projection lens for projecting the image, in which the image stored in the memory is read and visualized, so that the visualized image is projected via the projection lens onto a screen; and a remote controller for performing a remote control of the projector main frame,

wherein the projector main frame has a remote controller mounting section for detachably mounting the remote controller at a position that the mounted remote controller covers the front of the projection lens of the projector main frame,

wherein the remote controller has a medium drive in which a portable storage medium storing an image is detachably mounted and is accessed, and a transmission section wherein in a state that the remote controller is mounted on the remote controller mounting section, an image read from the portable storage medium mounted on the medium drive is transmitted to the projector main frame, and

wherein the projector main frame has an image receiving section for receiving the image transmitted from the remote controller to store the image in the memory.

5. A projector comprising: a projector main frame having a memory for storing an image in form of data and a projection lens for projecting the image, in which the image stored in the memory is read and visualized, so that the visualized image is projected via the projection lens onto a screen; and a remote controller for performing a remote control of the projector main frame,

wherein the projector main frame has a remote controller mounting section for detachably mounting the remote controller at a position that the mounted remote controller covers the front of the projection lens of the projector main frame, and

wherein the remote controller has a secondary battery for operating the remote controller, and the projector main frame has a charger section for charging the secondary battery of the remote controller mounted on the remote controller mounting section.

6. A projector comprising: a projector main frame having a memory for storing an image in form of data and a projection lens for projecting the image, in which the image stored in the memory is read and visualized, so that the visualized image is projected via the projection lens onto a screen; and a remote controller for performing a remote control of the projector main frame,

wherein the projector main frame has a remote controller mounting section for detachably mounting the remote controller at a position that the mounted remote controller covers the front of the projection lens of the projector main frame,

wherein the remote controller has: an imaging device; a focusing detection section in which an image on a screen projected from the projector main frame is formed on the imaging device to obtain an image signal representative of the image, and focusing of the image on the screen is detected in accordance with the image signal; and a focusing state transmission section for transmitting to the projector main frame information representative of the focusing state detected by the focusing detection section, and

wherein the projector main frame has a focusing control section for driving at least a part of construction element of the projection lens in accordance with information representative of the focusing state transmitted from the remote controller so as to focus the image projected onto the screen.

7. A projector comprising: a projector main frame having a memory for storing an image in form of data and a projection lens for projecting the image, in which the image stored in the memory is read and visualized, so that the visualized image is projected via the projection lens onto a screen; and a remote controller for performing a remote control of the projector main frame,

wherein the projector main frame has a remote controller mounting section for detachably mounting the remote controller at a position that the mounted remote controller covers the front of the projection lens of the projector main frame,

wherein the remote controller has: an imaging device; a distortion detection section in which an image on a screen projected from the projector main frame is formed on the imaging device to obtain an image signal representative of the image, and a keystone distortion of the image on the screen is detected in accordance with the image signal; and a distortion state transmission section for transmitting to the projector main frame information representative of a keystone distortion state detected by the distortion detection section, and

wherein the projector main frame has a keystone correction section for correcting the keystone distortion of the image on the screen.

8. A projector according to claim 7 , wherein the keystone correction section corrects the keystone distortion of the image on the screen based on the information representative of a keystone distortion state, the information being transmitted from the remote controller.

9. A projector comprising: a projector main frame having a memory for storing an image in form of data and a projection lens for projecting the image, in which the image stored in the memory is read and visualized, so that the visualized image is projected via the projection lens onto a screen; and a remote controller for performing a remote control of the projector main frame,

wherein the projector main frame has a remote controller mounting section for detachably mounting the remote controller at a position that the mounted remote controller covers the front of the projection lens of the projector main frame, and

wherein the projector main frame includes a light source lamp that emits light with which the projector main frame projects the image via the projection lens onto the screen, and the projector has a power source control section in which when the remote controller is mounted on the remote controller mounting section, a power supply to the light source lamp is turned off.
