The invention discloses a shutter correction method, which comprises the steps of controlling a shutter plate to be closed, and obtaining current image data output by an infrared detector; replacing the current parameter of the infrared detector by using a target parameter, wherein the target parameter is a parameter obtained according to image data acquired before the current image data; and sending a shutter opening instruction to the motor, so that the motor controls the shutter to be opened to finish shutter correction. According to the invention, the target parameter used when the currentparameter of the infrared detector is replaced is the parameter obtained by the image data collected before the current image data, but the parameter is not obtained by calculating current image data. After replacement is completed, a shutter disc is opened, to complete shutter correction. The shutter correction time is shortened since the target parameter acquisition process consumes a long timeand the target parameter acquisition process is not needed in the shutter correction process, and the shutter correction time is shortened. In addition, the invention further provides a device and anelectronic device with the advantages.
Description
technical field [0001] The present application relates to the field of imaging technology, in particular to a shutter correction method, device and electronic equipment. Background technique [0002] The shutter correction method adopted by traditional uncooled thermal imaging cameras is to adjust the configuration parameters of the infrared detector during the blocking period of the shutter, so that the average output value of the infrared detector reaches a target value after the shutter ends. When performing shutter correction in the existing method, since the calculation process of infrared detector parameters is performed in the middle of the shutter correction process, the current parameters of the infrared detector are replaced by the calculated parameters, so that the output of the infrared detector is adjusted to a suitable level , resulting in a longer shutter time. Generally, the shutter time takes more than 1 second from the start of image rigidity to the releas...
