Method and device for processing video image
First Claim
1. A method for processing a video image, comprising:
- receiving an original video image;
adjusting a signal clock frequency of the original video image to acquire a processed video image;
after a command signal input by a user is received, capturing the processed video image according to a preset size to acquire a video image corresponding to a display window of the preset size; and
encoding the video image corresponding to the display window of the preset size to acquire an encoded video image,wherein the command signal comprises a preset abscissa and a preset ordinate, wherein after the command signal input by the user is received, the step of capturing the processed video image according to the preset size to acquire the video image corresponding to the display window of the preset size comprises;
performing a pixel point computation according to a first formula to acquire the maximum number Ho of horizontal pixel points of the display window of the preset size, wherein the first formula is;

Abstract
A method and device for processing a video image are provided. The method comprises: receiving an original video image; adjusting a signal clock frequency of the original video image to acquire a processed video image; after a command signal input by a user is received, capturing the processed video image according to a preset size to acquire a video image corresponding to a display window of the preset size; and encoding the video image corresponding to the display window of the preset size to acquire an encoded video image. According to the method and device for processing the video image disclosed by the disclosure, new line, field and blanking synchronization signals are acquired through adjusting the clock frequency of an input image, and then, the corresponding capturing operation and outputting operation are performed according to the image display requirements of the user, so that the effect that video images with any resolution are reliably and stably displayed in the best display area range is realized.
