Embodiments of the present disclosure discloses a temperature detecting device, a temperature detecting system and a temperature detecting method. The temperature detecting device includes: a bearing support, a first end of the bearing support being fixed; a temperature detector, provided on a second end of the bearing support; a moving component, configured to be connected with the bearing support, wherein the second end of the bearing support is movable with respect to the first end under driving of the moving component.

Temperature detecting device, temperature detecting system and temperature detecting method

A digital camera comprising a watermark-adding device, which comprises a device for obtaining the signal values of digital signals, a bits dividing device, an altered regions initializing device, an eigenvalue calculating device, an encrypting device and a watermark embedding device. The bits dividing device divides the data recording each pixel point of the digital image, on the basis of bit, into bits for calculating the eigenvalue of the image, bits for hiding the watermark and bits for locating altered regions. The altered regions initializing device can set all the data of the bits for locating altered regions to 0 or 1. The eigenvalue calculating device can calculate the eigenvalue of digital signals. The encryption device encrypts the calculated eigenvalue. The watermark embedding device embeds the eigenvalue information in the digital signals.
