The portable computer 1 includes a base 10, a display device 12, an image capturing device 14, an image capturing switch 16, a processor 18, and a first storage device 20.
In FIG. 1, the display device 12 includes a frame 120 pivotally connected to the base 10. In other words, a user can open or close the display device 12 relative to the base 10. The image capturing device 14 and the image capturing switch 16 are disposed at the frame 120. In FIG. 2, the processor 18 and the first storage device 20 are disposed in the base 10. The processor 18 is electrically connected with the display device 12, the image capturing device 14, the image capturing switch 16, and the first storage device 20.
In the embodiment, the display device 12 may be a liquid crystal display or other screens having a display function. The image capturing device 14 may be a charge-coupled device camera (CCD camera), a complementary metal-oxide-semiconductor camera (CMOS camera), or other active pixel sensors. The processor 18 may be a central processing unit (CPU) or other processing units.
When a user is to capture images, he or she can press the image capturing switch 16 to output a first request signal 160 to the processor 18 during the portable computer 1 is under a main-power-off state. After the processor 18 receives and recognizes the first request signal 160, it drives the image capturing device 14 to capture a first image under the main-power-off state and instantly displays the captured first image on the display device 12. Thereby, the user can operate the portable computer 1 to capture the images and to instantly display the captured images under the main-power-off state.
In addition, at the same time the processor 18 can store the captured first image to the first storage device 20. The first storage device 20 may be a hard disk or other similar storage devices. In a practical application, the first storage device 20 is generally a main storage device built in the portable computer 1, and it is mainly used as a media for storing files and operating systems.
The main-power-off state indicates that main power of the portable computer 1 does not need to be turned on, and the function can be completed only by starting part related electronic elements when the portable computer 1 does not enter the operating system. According to the above, the image capturing device 14, the display device 12, the processor 18, the first storage device 20, and necessary power modules (not shown) such as a battery, an external power transformer and so on can be started only by pressing the image capturing switch 16. The main-power-off state mentioned hereinafter conforms to the definition here that the portable computer does not enter the operating system and part related electronic elements are started only via special programs.
In the embodiment, the portable computer 1 can further include a file copying switch 22 and a connection interface 24. The file copying switch 22 is disposed at the frame 120. The file copying switch 22 and the connection interface 24 are electrically connected with the processor 18, respectively. The connection interface 24 may include at least one of a universal serial bus (USB), an IEEE 1394 specification, a serial digital input output (SDIO), or other similar memory card slot interfaces. In FIG. 2, the connection interface 24 can be used to connect a second storage device 3. In a practical application, the second storage device 3 may be a flash memory portable disk, a portable hard disk, a portable optical drive, a secure digital card (SD card), or other storage media.
When the user is to display the second image stored in the second storage device 3, he or she can connect the second storage device 3 to the connection interface 24 and then press the file copying switch 22 to output a second request signal 220 to the processor 18. In response to the second request signal 220, the processor 18 copies the second image from the second storage device 3 to the first storage device 20 under the main-power-off state. In other words, via the connection interface 24, the user can directly connect a memory card of a digital camera or a personal mobile hard disk with the portable computer 1 in the embodiment. Thus, under the main-power-off state, the currently captured photos are fast transmitted to the portable computer 1 and are displayed via the display device 12.
In the embodiment, the portable computer 1 can further include at least one image playing switch 26. In FIG. 1, the portable computer 1 includes three image playing switches 26. The number of the image playing switch 26 can be determined according to a practical application, and it is not limited to three.

When the user is to display the images under the main-power-off state, he or she can press the image playing switch 26 to output a third request signal 260. In response to the third request signal 260, the processor 18 displays the images stored in the first storage device 20 on the display device 12 according to a predetermined play mode by the users under the main-power-off state. Each image playing switch 26 can be designed to output a different third request signal 260 according to the users' different needs. The third request signals 260 correspond to a play instruction, respectively, such as starting play, stopping play, previous, next, reverse, forward play, reverse play, setting a play mode and so on. The play mode includes a random play mode, a mode of playing in order, or other specific play modes.
In the embodiment, the portable computer 1 can further include a wireless receiver 28. In FIG. 2, the wireless receiver 28 is disposed in the base 10 and electrically connected with the processor 18. The wireless receiver 28 is used to receive a fourth request signal 50 from a remote control 5. In response to the fourth request signal 50, the processor 18 displays the images stored in the first storage device 20 on the display device 12 under the main-power-off state. In a practical application, the remote control 5 can output different fourth request signals 50 corresponding to different play instructions according to the users' different needs. For example, the play instruction may be starting play, stopping play, previous, next, reverse, forward play, reverse play, setting a play mode and so on.
According to the users' operation, the remote control 5 can output a fifth request signal 52 transmitted to the processor 18 via the wireless receiver 28. In response to the fifth request signal 52, the processor 18 drives the image capturing device 14 to capture a third image under the main-power-off state and instantly displays the captured third image on the display device 12. In addition, the processor 18 can also store the captured third image to the first storage device 20.
The method for capturing images and copying files via the remote control 5 is the same as the method mentioned above. The difference is that in this method the request signals can be transmitted via a wireless remote control. Therefore, it is not described for a concise purpose.
FIG. 3 is a schematic diagram showing an appearance of the remote control 5 in FIG. 2. In one embodiment, the wireless receiver 28 may be an infrared receiver. The corresponding remote control 5 may be a remote control with a specification of a personal computer memory card international association (PCMCIA), such as an express card remote control or a new card remote control, including an infrared transmitter.
