摘要： A method for synthesizing JPEG image and method and apparatus for superimposing OSD information onto JPEG image. The method for synthesizing JPEG image comprises performing entropy decoding, AC/DC coefficient decoding, inverse DC prediction and inverse quantization on the JPEG bit stream of a first image and a second image to obtain DCT coefficients; synthesizing the DCT coefficients in the order of JPEG raster scan according to the image stitching mode; and performing quantization, DC prediction, AC/DC coefficient encoding and entropy encoding on the synthesized DCT coefficients to form a bit stream of a synthesized image. For superimposing OSD information, only the region of the image to be superimposed is transformed by an IDCT. The OSD information is superimposed in the YUV plane and converted to DCT coefficients by DCT. The DCT coefficients superimposed with OSD information are synthesized with the DCT coefficients of non-superimposed region of the image.

摘要： A video camera includes a first temperature sensor, a control logic circuit, a main system, a heating module, a fan and a power supply. After the power supply supplies power to the video camera, the first temperature sensor comes to be active, when the temperature sensed by the first temperature sensor is less than T1, the first temperature sensor outputs a control signal to the control logic circuit, which activates the heating module and the fan and prevents the power supply from supplying to the main system; and when the temperature sensed by the first temperature sensor is greater than T1, the first temperature sensor outputs a control signal to the control logic circuit which enables the power supply to supply to the main system and inactivates the heating module and the fan, and therefore, a normal activation and stable operation of the video camera at low temperatures are ensured.
