[0042] The core idea of the present invention is: the decoder notifies the encoder of the position information of the local enlarged area, and the encoder only encodes the preset coding area centered on the local enlarged area, thereby improving The resolution of the local enlarged area is improved. Wherein, the resolution of the preset encoding area is smaller than the resolution of the camera, but greater than or equal to the resolution of the encoded output image.
[0043] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0044] figure 2 The flow chart for zooming in on a local area of an image captured by a camera provided in Embodiment 1 of the present invention, as shown in figure 2 As shown, the specific steps are as follows:
[0045] Step 201: The user determines the zoomRect area, and inputs the ZoomRect area position parameter into the decoder, and the decoder sends the Z...
