2. Related Art
Under many circumstances, a user is often disturbed by some external factors when watching an audio-video program. For example, the user has to go out upon an invitation from a friend when watching a ball game, and thus cannot finish the rest of the game, or the user cannot watch a movie played at 8:30 PM on time due to some reasons. At this time, most people will record the aforementioned programs in advance and watch them later in free time. However, to achieve the above purpose, a digital video recorder or a computer system is needed, which is not suitable for most of the people. Moreover, when the user intends to capture some pictures of a wonderful program when watching, the aforementioned method should also be employed, which is quite inconvenient in operation.
Referring to ROC Patent Publication No. M286528, a digital video recording TV equipment is disclosed, which includes an image receiving unit for receiving a digital image from an external camera. Then, an audio-video processing unit is utilized to process the digital image and an audio signal received by a microphone, so as to output an audio-video signal to a storage unit. Furthermore, a central processing unit (CPU) receives and processes the audio-video signal and a television signal from the external, so as to display the image of the audio-video signal or the television signal on a display.
Although in the aforementioned patent, a monitor picture and a TV program picture can be switched and preserved on the same display, thus achieving the purpose of preservation and entertainment. However, the picture or content of a TV program cannot be captured or recorded, so it is still inconvenient in operation.
Therefore, it has become one of the issues to be solved by researchers that how to provide an image capture method and an audio-video recording method of a multi-media electronic device, so as to enable the user to store, capture and record a TV program that is being played without adopting any external storage devices.
Accordingly, the present invention is directed to provide an image capture method and an audio-video recording method of a multi-media electronic device, wherein memories are built in the multi-media device, the image or audio-video data captured or recorded in real time is de-interlaced and then output, so as to improve the operation convenience of the multi-media electronic device.
Therefore, to achieve the aforementioned objective, the image capture method of the multi-media electronic device provided by the present invention comprises: first, receiving a sequential image data; storing the image data into a first memory (for example, a volatile memory) according to an image storage instruction; performing a de-interlace process (for example, single-field de-interlace, dynamic adaptive de-interlace or dynamic compensation de-interlace) on the image data in the first memory; and storing the de-interlaced image data into a second memory (for example, a non-volatile memory).
Further, to achieve the aforementioned objective, the audio-video recording method of a multi-media electronic device provided by the present invention comprises: first, receiving a sequential audio-video data; storing the audio-video data into a first memory (for example, a volatile memory) according to an audio-video recording instruction; performing a de-interlace process (for example, single-field de-interlace, dynamic adaptive de-interlace or dynamic compensation de-interlace) on the audio-video data in the first memory; and storing the de-interlaced audio-video data into a second memory.
By using the image capture method and audio-video recording method of a multi-media electronic device, the user can capture or record the images or audio-video contents played in the multi-media electronic device in real time without the help of any externally-connected storage devices of large capacity, thereby improving the operation convenience of the multi-media electronic device and enhancing the additional functions thereof.
The features and practice of the present invention are illustrated below in detail through preferred embodiments with reference to the drawings.
Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
The present invention will become more fully understood from the detailed description given herein below for illustration only, and thus are not limitative of the present invention, and wherein:

Next, the image data in the first memory is de-interlaced (Step 102). As the received image data is of an interlaced image data format, to align the image with a time axis in a progressive scan display unit, a de-interlace process is needed here to improve the picture quality. The de-interlace process, such as single-field de-interlace, dynamic adaptive de-interlace or dynamic compensation de-interlace, can be adopted.
Afterward, the de-interlaced image data is stored in the second memory (Step 103), wherein the second memory is a non-volatile memory, such as an erasable programmable read-only memory (EPROM), an electrically erasable programmable read only memory (EEPROM) or a flash memory.
Then, the image data is selected from the second memory to be edited (Step 104), wherein the image data can be named, edited and deleted by a user. Finally, the image data is output from the second memory (Step 105) to a peripheral device (for example, a printer), wherein the image data in the second memory is output to a printer through a wireless or wired transmission mode.

Next, a de-interlace process is performed on the audio-video data in the first memory (Step 202). As the image data in the received audio-video data is of an interlaced image data format, in order to align the image with a time axis in a progressive scan display unit, the de-interlace process is needed here to improve the picture quality. The de-interlace process, such as single-field de-interlace, dynamic adaptive de-interlace or dynamic compensation de-interlace, can be adopted.
Afterward, the de-interlaced audio-video data is stored in a second memory (Step 203), wherein the second memory is a non-volatile memory, such as an EPROM, an EEPROM or a flash memory.
The audio-video data is selected from the second memory to be edited (Step 104), wherein the audio-video data can be named, edited and deleted by a user. Finally, the audio-video data is output from the second memory (Step 105) to a peripheral device (for example, a screen and/or a loudspeaker), wherein the audio-video data in the second memory is output to the screen and/or loudspeaker through a wireless or wired transmission mode.

Additionally, when recording the interlaced image data 14, the user can return to enjoy the previous audio-video content at any time, and meanwhile the multi-media electronic device continues recording the current audio-video data. For example, the user begins recording from the (i−1)th data and enjoy the corresponding audio-video content at the same time. When the program proceeds to the (i+35)th data, the user can still return to enjoy the audio-video content of the (i−1)th data via a control menu, and meanwhile the multi-media electronic device continues recording the audio-video content following the (i+35)th data, such as the (i+36)th data, (i+37)th data. As such, the operation convenience of the multi-media electronic device is greatly enhanced.
By using the image capture method and the audio-video recording method of the multi-media electronic device, the memories are built in the multi-media electronic device to store the image data or audio-video data to be captured or recorded. As such, the user may capture or record the image or audio-video content played in the multi-media electronic device in real time without the help of any externally-connected storage devices of large capacity, thereby improving the operation convenience of the multi-media electronic device and enhancing the additional functions thereof.
The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
