The frame is characterized in that the main chip comprises a decoding module (120) for decoding pictures; an image zooming module (130) for zooming the image data after being decoded; a coding module (150) for coding the image data after zooming, thus to be conveniently stored in the memorizer.
Description
Technical field
The utility model relates to a kind of digital album (digital photo frame).
Background technology
Digital album (digital photo frame) is a kind of digital display type photo frame.It is compared with traditional photo frame, has obvious superiority, and not only memory space is big, and people can change photo, background, music etc. at any time.The ultimate principle of digital album (digital photo frame) is exactly to adopt the moulding of common photo frame, and the photo in the middle of the original photo frame is partly changed into LCDs, mixes power supply, storage medium etc.Can play-over digital photograph, making can loop play in the same photo frame.Its Core Feature is passed through liquid crystal display or other display equipment output with the image file in the medium through decoding conversion back.
The medium of existing file storage, connected mode has following several: one, read the file that is stored in various digital cards, portable hard drive or other similar devices by the mode that directly links to each other; Two, read the file on other equipment in the network by network or blue tooth interface; Three, directly read file on the local memory.Wherein, the product that contains the third function must be provided with storer in digital album (digital photo frame).
In present product, the general storer that uses jumbo NAND type FLASH storer as digital album (digital photo frame) of traditional digital album (digital photo frame) directly carries out the storage of file.But doing like this to increase more cost.And general digital album (digital photo frame) all uses a slice to be used for the storer of stored program NOR type FLASH storer as digital album (digital photo frame), use this NOR type FLASH memory cost very low, but its capacity is less.
On the one hand, existing digital camera is substantially all more than 3,000,000 pixels, representative value is more than 5,000,000 pixels, and still increasing, such photo uses general jpeg format storage size nearly all more than the 1M bit, obviously is not enough if do not add the low capacity memory device, stores of handling directly with representative value 2M bit.On the other hand, the resolution of existing display device is far smaller than the resolution of picture itself.With 7 cun simulation liquid crystal displays is example, and its typical resolution is 480*234, is slightly more than 110,000 pixels.The picture of millions of pixels is for such screen, and its details can't show on equipment that most of data of image file are unnecessary redundancies for showing like this on digital album (digital photo frame).
The utility model content
The purpose of this utility model is to provide a kind of digital album (digital photo frame) that can overcome the above problems.
In order to achieve the above object, the utility model provides a kind of digital album (digital photo frame), and described photo frame comprises storer and master chip, it is characterized in that master chip comprises: decoder module, the picture of storage is decoded; The image zoom module is carried out convergent-divergent with decoded view data; Coding module will be encoded through the scaled images data.
As a preferred version of the present utility model, described storer is a NOR type FLASH storer.
As another preferred version of the present utility model, described storer is used for stored programme and picture;
As another kind of preferred version of the present utility model, the decoder module of described master chip is that the jpeg format image that reads in is decoded.
Another is preferred as of the present utility model, and described coding module is that a coded image data that reads in is become the jpeg format picture.
The utility model is encoded again by the view data after the picture decoding is carried out convergent-divergent, has solved the problem of utilizing small-capacity memory storage plurality of pictures.
In the utility model, storer is NOR type FLASH storer preferably.And the method that the utility model provides also can be used under other the storer situation, can store more picture under the situation that does not increase memory span; Pass through the image zoom module simultaneously the view data of the suitable display device resolution sizes of compression of images one-tenth, show for digital album (digital photo frame) like this, just removed the redundancy of the view data of unnecessary high pixel.
Description of drawings
Below with reference to accompanying drawings specific embodiments of the present utility model is described in detail, wherein:
Fig. 1 is the digital album (digital photo frame) structured flowchart according to an embodiment of the present utility model.
Embodiment
Fig. 1 is the digital album (digital photo frame) structured flowchart of an embodiment of the present utility model.As shown in Figure 1, this digital album (digital photo frame) comprises: storer 200, exterior storage medium interface 300, display device 400, SDRAM or DDR storage and other peripheral components 500, master chip 100, wherein master chip comprises: decoder module 120, image zoom module 130, coding module 150.In a preferred version, master chip 100 also comprises: image processing module 140, image display 160, main control MCU 110.
The work of main control MCU 110 control decoder modules 120, image zoom module 130, image processing module 140, coding module 150 and image display 160.
120 pairs of pictures of decoder module are decoded.In a preferred version of the present utility model, decoder module 120 is the jpeg format picture decodings to reading in.
130 pairs of decoded view data of image zoom module are carried out convergent-divergent.In the preferred version of utility model, be the view data that decoded image data scaling is become to be fit to the display device resolution sizes.
140 pairs of view data of image processing module are carried out Flame Image Process.In one embodiment, be the Flame Image Process that view data is suitable for showing.
Storer 200 is used for stored programme.In a preferred version, storer 200 is used for stored programme and picture.In another preferred version, storer 200 is NOR type FLASH storeies.
Exterior storage medium interface 300, being used for exterior storage medium provides picture to master chip.In a preferred version, the exterior storage medium interface comprises various digital card such as USB interface, serial line interface, parallel interface, blue tooth interface, infrared interface, SD card, mmc card interface, MS card and XD card.
SDRAM or DDR storer and other peripheral components 500 are used for working procedure and finish the work of digital album (digital photo frame).
The course of work below in conjunction with the digital album (digital photo frame) structural drawing logarithmic code photo frame of an embodiment of the present utility model is done specific description.
Read picture from exterior storage medium, the process that deposits storer in is as follows:
At first, decoder module 120 is received the instruction of main control MCU 110, by exterior storage medium interface 300 picture is read in, and passes to image zoom module 130 after decoding.
