DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image reproducing apparatus capable of reproducing image data recorded on a recording medium such as a hard disk and displaying an image corresponding to the image data on a monitor. .

[0002]

2. Description of the Related Art At present, personal computers that are widely used include a main memory and a hard disk drive (H).
A hard disk in the HDD device stores an OS (Operating System) such as Windows (registered trademark of Microsoft Corporation) and various kinds of application software (hereinafter referred to as application software).

When the user presses the power button while the power of the personal computer is set to off, the power of the computer is turned on and the HD is turned off.
OS is read into the main memory from the device D, and the OS
Is started. Subsequently, when the user performs an operation for starting the desired application software, the desired application software is read from the HDD device into the main memory, and the application software is started. Thereafter, the user can cause the personal computer to perform processing according to the application software.

In order to turn off the power of the personal computer, the user first performs an operation of terminating the running application software to terminate the application software, and further performs an operation of terminating the OS so as to terminate the OS. Then, the power button of the computer is pressed to turn off the power.

In a personal computer in which application software and an OS are recorded on a hard disk as described above, if the power is turned off in a state where the application software and the OS have not been terminated, data of the data recorded on the hard disk will be lost. Contents may be destroyed. For this reason, when the computer is to be turned off, as described above, the application software or the O
It is necessary to perform an operation to end S. In the case of a personal computer, if the power is switched off in a state where the application software and the OS have not been terminated, the destruction of data contents in the hard disk is discovered at the next time the power is turned on. When the data content is destroyed, a process for restoring the data content is executed.

In recent years, a high-definition moving picture device capable of recording high-definition moving picture data on a hard disk and reproducing the high-definition moving picture data recorded on the hard disk has been developed.
In such a high-definition moving image device, it is conceivable to adopt a configuration in which an OS and application software are recorded on a hard disk in an HDD device, similarly to the personal computer.

[0007]

High-definition moving picture devices are being developed not only for users of personal computers but also for children and elderly people, and various kinds of devices such as television receivers are being developed. Operation is required to be simple. However, when the above configuration is adopted in the high-definition moving image apparatus, when the power of the apparatus main body is not set to be turned off, the user performs an operation of ending the application software, further performs an operation of ending the OS, and then performs a power supply operation. You have to press the button. Requesting such a complicated operation when turning off the power of the apparatus main body is a problem in a high-definition moving image apparatus which requires simplicity of various operations as described above.

In order to solve the above problem, a configuration in which application software and an OS are recorded in a ROM is conceivable. In such a configuration, even if the power of the apparatus main body is turned off in a state where the application software and the OS have not been terminated, the data contents are not destroyed as described above. Therefore, when turning off the power of the apparatus main body, the application software and the OS
Is not required, and the user only has to perform a simple operation of pressing the power button. However, in the configuration employing the ROM, there is a problem that the cost of the device body is higher than that in the configuration employing the hard disk drive. Accordingly, an object of the present invention is to provide an image reproducing apparatus in which software such as application software and an OS is recorded on a hard disk, wherein the operation when turning off the power of the apparatus main body is simple. That is.
