[0080] In this embodiment, the region selection instruction includes termination coordinates;
[0081] Correspondingly, the determining the position of the region selection frame specifically includes:
[0082] S101: Obtain the current coordinate information of the area selection frame;
[0083] It should be noted that the system itself has a plane coordinate system of the outputtable area U (current screen), and the plane coordinate system of the outputtable area U can be established by the electronic pan-tilt system itself, or can be directly obtained from other shooting devices. Obtain (for example, you can obtain the space rectangular coordinate system from the panoramic camera, and convert its space rectangular coordinate system into the plane coordinate system of the output area U); any point in the current screen is relative to the plane coordinate system of the output area U It is fixed;
[0084] Understandably, referring to figure 2 , the region selection box R ma...

[0095] In this embodiment, the scaling of the original image in the region selection frame to the expected output resolution specifically includes:
[0096] S401: Determine the scaling base according to the expected resolution;
[0097] It is understandable that the resolution value PPI (Pixel per inch) is a parameter used to measure the amount of data in the image, that is, how many effective pixels are in the image. The higher the resolution value PPI, the higher the resolution of the image. higher rate; reference figure 2 , since the resolution of the outputable area U has been fixed, the size of the virtual frame R (region selection frame) is 800×600 (its effective pixels in the horizontal and vertical directions), and the smaller the virtual frame R, the higher the PPI value; Correspondingly, the scaling base is determined according to the expected resolution, that is, how many effective pixels are estimated according to the expected resolution;
[0098] Therefore, whe...

[0104] In this embodiment, before the outputting the image data in the area selection frame, the method further includes:
[0105] S45: Preprocess the image data in the region selection frame to remove noise existing in the image.
[0106] It is understandable that after the image captured by the image sensor is usually zoomed, some black and white light and dark noises generated by the image sensor, transmission channel, decoding process, etc. may appear randomly, or some random noises appear. The point of intensity value or black intensity value, thus affecting the final output picture quality;
[0107] In the specific implementation, the above-mentioned possible image noise can be removed by the smoothing filtering method, that is, the average gray value of the pixels in the neighborhood of the image to be displayed determined by the filter mask is used to replace the average gray value of each pixel of the image. value, which can improve the image to be displayed when the...
