Digital camera capable of automatic momitoring environment change

Abstract

A digital camera consists of a timing unit for exporting a start up signal at preset time, camera body for catching up current image and to convert it to be a current image parameter, a storage unit for storing image data and control unit being coupled with abovesaid timing unit. The current image is catched by the camera when the camera receives start up signal and then to convert the current image into current image parameter as well as to compare it with the previous one. The current image parameter is stored in the storage unit and to use it to replcace the previous image parameter if theimage parameter difference is reached to a preset grade and the current image parameter is only used to replace the previous one if the image parameter difference is not reached to the abovesaid preset grade.

Description

technical field [0001] The present invention relates to a digital camera, in particular to a digital camera that automatically monitors environmental changes. The digital camera is used to regularly extract images and compare them with previous images. If there is a difference, the newly extracted images are stored to achieve long-term monitoring. method. Background technique [0002] Generally speaking, the device currently used as a security system continuously shoots images of the area to be monitored through a video recording device. Regardless of whether the captured images change or not, they are all captured and stored in a video tape. The above-mentioned recording equipment is continuously powered, so the power consumption is a disadvantage, and most of the video tapes may record some identical images.

Problems solved by technology

[0002] Generally speaking, the device currently used as a security system continuously shoots images of the area to be monitored through a video recording device. Regardless of whether the captured images change or not, they are all captured and stored in a video tape. The above-mentioned recording equipment is continuously powered, so the power consumption is a disadvantage, and most of the video tapes may record some identical images

On the other hand, since general digital cameras already have the function of timing Selfie, such as once every few seconds to several hours, when the set shooting cycle is shorter (every few seconds), the memory may be filled up quickly , and can no longer monitor

In addition, if the shooting cycle is longer (every few hours), it will not be able to capture the changes within a few minutes. Moreover, the above-mentioned digital camera will also consume a lot of power because it is in a stand by state. , so it does not have the ability to save power for long-term monitoring

However, no matter whether the captured image has changed or not, the above-mentioned digital camera will always shoot it and store it in the memory, so the image stored in the memory may be the same, resulting in a waste of memory space, and when the memory is insufficient, it cannot Execute the monitoring function
