Description of the invention (1) The present invention relates to a digital phase of the age monitoring environment change = the eyepiece 'special image' and comparison with the previous image. If: t is digitally similar 'to achieve long-term debt measurement, the difference is stored. Generally speaking, Juqian uses video equipment, Lian # β Μ 4 as a security system to shoot continuously. If you want to damage H Zhuxi, you need to-straight; f to the above recording equipment 'cause image 2 :: and most of the video tape may be memorized, because the general digital camera has been i: such as every few seconds-once to several hours-times: the shorter ( Every few seconds), making it possible for the memory to no longer be monitored. In addition, if it is a shooting cycle), it will not be able to capture changes within a few minutes, and the digital camera will also consume a lot of power because it is in stand by, so it does not have the power-saving long-term detection capability. If there is any change in the image, the above digital cameras will always be in the memory, so the image stored in the memory will cause a waste of memory space, and when the memory performs the monitoring function. ^ In view of this, the purpose of the present invention is to automatically start every predetermined time to capture a current image for comparison. If the current image and the image have reached a predetermined level, it indicates the environment Has changed, it is about a kind of automatic machine to periodically capture the video and save the newly captured video. It is through an image, no matter it is taken in a videotape, the consumption of this power. Some of the same videos have timed selfies. The set shot will be quickly filled, the bigger it is (repeated for several hours, and the state of power on, power consumption. But when the shot is taken and the storage may also be the same insufficient, that is, the digital camera ca n’t regularly time the image, The difference from a previous image

Description of the invention (2) ^ into the 5th memory, and then shut down; if the difference between the above items does not reach the J-mesh image and the previous shadow measurement 2. To extend the time when the memory is full, and to achieve the above-mentioned objective with reliable detection, the present invention improves the monitoring capability. The digital camera includes at least a timing sheet ^, an automatic monitoring environment change storage unit, a control sheet, a digital camera body, and a consistent output at a given time; words: n unit 1 is used to extract every time-the current image And converted into a current machine body, used to compare the above current shadow parameters enable the above current image parameters with the previous previous shirt image parameters. At a given level, the above current images have reached a difference of -2. 'And the above-mentioned current image parameter 2 = the above-mentioned current image parameter and the previous image parameter of the storage unit; if the degree, only the above-mentioned current image is used; and the above number. Instead of the above-mentioned image, the embodiment is shown in the first figure, which is a schematic diagram of the camera. The number 100 of the automatic monitoring of the C environment change of the present invention includes a timing unit, 0, and the digital camera enable signal Enl, which is refined by the orphan and the brother, is used;-the digital camera outputs-an image at a fixed time, and is converted into-at present Material parameters; capture-the current shadow is stored early, used to store the 5th page 0723-7663TWF (n); dennis.ptd 122U364 V. Description of the invention (3) Digital image data; When the degree of current image parameters is above, the degree of current image parameters will be used to determine the degree of current image parameters. Among them, the above-mentioned enabling letter is displayed in seconds, 10 seconds, and 30 for adjustment. In addition, the camera body 2 describes the light change from the given time to the evening, for example, unit 40 will consider that the difference has not reached the previous one, and avoid storing too much. The degree of difference is the current image parameter data. For example, German control, early Yuan 30, is coupled to the timing unit and receives, which causes the digital camera to capture the above step = the visual image parameter and a previous image parameter. The current image parameters are stored until the previous 2 is stored to replace the previous image parameters. If the above is only two, the difference between the previous image parameters does not reach the above. Only the current image parameters are used to replace the previous image reference timing sheet 7C. 10, used to enter the number Enl at a predetermined time τ. For example, the predetermined time D can be 5 seconds, 60 seconds, 90 seconds, etc., which can be set by the user. 'The timing unit 10 is a timer. When the above number is turned off (Turn of f), continue to count up and output the above-mentioned enable signal Enl. In addition, because of daytime changes, insects fly by, etc., it is not a significant environment for strangers to enter and have cars Enter and so on, so the above control of the difference between the current image parameters and the previous image parameters is not to store the current image parameters, so it is unnecessary Image. Of course, between the above two image parameters according to different purposes and make the appropriate of adjustment. Further, the above and previous image parameter line as in a digitally represented image, the above-described digital camera body 20 may be a still digital camera
