Description of the invention: [Technical field to which the invention pertains] The present invention relates to a method for managing a storage space of a camera, in particular, a storage space management method for a health camera. [Prior Art] As with traditional shooting, the number of handsome machines is the feeding information format. (4) Save the memory card to save 'and save space'. Usually the photo information will be compressed before being stored in the digital memory card. 'If you save the image mark of the distortion compression format such as G, GIF. The image compression ratio of θ ', ′′ ' & ageing Wei axis machine seems to maintain the image above a certain quality as the setting target, so that when the user transfers the image mark to a general physical photo, 'there is no lattice shape Or the situation of ambiguity, but due to the rapid changes in the current digital camera technology, the manufacturing technology of sensitization has also been greatly improved. Therefore, digital cameras with millions of veils or more have become market trends; in this case, as early as the file The capacity of the memory card is also relatively increased due to the increase in the quality of the element. Therefore, the number of images that are often taken is not much, but the memory card capacity is not too small, and the video file is not important, or the memory is replaced. The memory card is solved and solved, but this method is not suitable for certain specific situations and the needs of the user. For example, the turtle has only one memory card, the captured image is only used as a webpage, and the memory card is used. Deviated mussels also cause a burden on consumers. In this mouth, the video slot film shot by the digital camera actually has a transfer to the general entity, for the sake of the slaves, and when the capacity of the card is about to run out, the mobile can not be used. Protecting the image file's finer ratio and recompressing it, it can protect the must-have 1253290. The shadow of the film is not the same as the low-shadow _, but also good _ card space to reduce the burden on consumers, actually on the market I am eagerly looking forward to the above reasons. The present invention proposes a new storage space management method for digital cameras. SUMMARY OF THE INVENTION The object of the present invention is to provide a storage space management method for a digital camera, which enables the camera to realize large-capacity storage and is easy to store and operate. The purpose of this month is to implement a storage space management method for a digital camera through a town technology solution, which comprises the steps of: automatically detecting whether the remaining storage space in the storage medium of the camera is sufficient to accommodate at least one new photo; When the storage space is insufficient, according to the remaining remaining storage, the compressed job line in the storage medium is decompressed, and a new _ ratio is generated, and the decompressed photo is logged on and stored in the storage medium; Repeat the previous steps, the remaining storage of the direct storage medium is vain to accommodate the aforementioned new photo, and the new photo is stored in the storage medium. With the prior art, it is difficult to achieve a large capacity in the _ empty _, and the nutrients are edited by the camera, and there is no work. This makes the digital camera using this storage space method more intelligent and easier to operate. [Embodiment] In the age management of a general digital camera photograph, in order to save space, it is common to use the 1 algorithm standard to perform the processing of the photo_signal and then age. The storage space management method of the digital camera according to the preferred embodiment of the present invention adopts a 1253290 compression mark (oint Photographic Experts Group), and the storage method includes the following steps: a) automatic "camera" The size of the storage space in the storage medium is determined to be sufficient to accommodate at least one new photo; b) when the storage space is insufficient, the compressed storage medium is decompressed according to the storage space of the foregoing_C; Generating a new compression ratio, recompressing the previously decompressed photo and storing it in the storage medium; d) repeating steps a), b) and c) until the remaining storage space of the storage medium is sufficient to accommodate the foregoing Up to the new photo; and e) store the new photo in the storage medium. Among them, the above-mentioned JPEG standard is an internationally-acceptable lossy compression algorithm that can efficiently compress _images. In this algorithm towel, _ The data is first assigned to the block, and Discrek Cosine Transform (DCT), quantization, and Huffman coding as variable length coding are performed for each block ( Huffmanc〇ding). Using this lossy compression method, the image obtained by compression and comparison is compared with the original image, even if the compression ratio is 25:1, it is difficult for non-image experts. Finding the difference between them, so the jpEG standard is widely used in the field that requires large-scale compression storage. Clear reference diagram 'The first figure shows a system for storing space management method of a digital camera according to a preferred embodiment of the present invention. First, the camera is turned on, and the system is initialized (step s0. After the initialization is completed, the camera starts mode detection (step S2), at which time the system! 25329 〇 green indicates that the operator sets/changes the camera mode (step S21). After the mode setting is completed, the camera enters the standby state 'Wait and judge whether the operator's operation command is received (step magic), enter camera operation 4 (see the second figure). At this time, the operator can use the camera's operation panel to the camera. Control such as shooting, set "Operation. After all operations are completed, the operator enters the end signal (go to S4) 'System check _ End the money and close, the domain stops working.

As shown in the figure, when the camera finishes focusing (the step is, the system can allow the operation phase to step through the parameter setting (step 2 (8), such as adjusting the size and length of the exposure daily pin, etc., of course, this action can also be in the initial setting of the camera mode. Complete (step milk, see the first picture). After the parameter setting is completed, the operator can decide whether to shoot (step 2〇3). If the operator gives up shooting, the system returns to the initial state of the work, and the camera is dissipated. After the operator performs the shooting, the camera system automatically detects the storage (step _) and the space size adjustment setting by the camera system. After setting the money, the device displays through the liquid crystal display - the dialogue surface to report whether the author needs to store the film (Turning 205) and transferring the photo input protection setting (step 206). After the above steps are completed, the system ends the shooting work. The system enters the aforementioned step 2〇4 after the operator presses the button, that is, the system automatically detects the storage space. And automatically adjust the size of the space, in order to save the storage requirements, the specific step of the step is the third step of the wei shui street _ said, if the age card available for storage space is insufficient When at least - a new photo is stored, the system retracts the original photo to release the storage space until the storage card is available with sufficient storage space to end the _ program into the second step. In the third figure As shown in step 301, the system determines whether the storage space is not 8 1253290; in step 302, the system detects the status of each existing photo, including detecting whether the existing photo has been compressed. If the photo is found to have been compressed, Then the photo will go to the step · to solve the solution _. Otherwise 'if the step 2 towel _ check _ show that the photo in the memory card has not been _, then the system proceeds to step 3 〇 21 to ·. In this step 3 milk to In the ship 2, the system checks the status of the uncompressed photos one by one, and checks whether the photo is protected. When the ', ,, and phrase 7C becomes the solution, the system automatically sets the photo—the new Wei ratio is the K value (+ Step 304), and the calibrated photo is taken according to the ratio _ (step and then stored), the squaring program ends, and the system returns to step 3 〇 1. where 'in the aforementioned decompression process (step 3 〇 3), the system is based on storage The remaining work size of the card is determined by the number of photos decompressed hundreds of times.
