Video processing device, video processing method, monitor apparatus, computer device, and medium

A video processing device, comprising:

• a receiver, a normalization processor, a selector and an image processor;
• wherein the receiver is connected to the normalization processor, the normalization processor is connected to the selector, and the selector is connected to the image processor;
• the receiver is configured to receive an original video image;
• the normalization processor comprises a plurality of normalization sub-circuits each configured to perform format adjustment on the original video image to generate a video image in a target format, wherein different ones of the normalization sub-circuits perform the format adjustment in different manners;
• the selector is configured to output the video image generated by at least one of the normalization sub-circuits to the image processor according to a received selection instruction;
• and
• the image processor is configured to generate an image to be displayed from the received video image,
• wherein the image processor comprises an image processing sub-circuit, a direct output sub-circuit, and a merger sub-circuit, and the image processing sub-circuit and the direct output sub-circuit are each connected to the merger sub-circuit,
• the image processing sub-circuit is configured to perform image processing on the received video image to generate an optimized video image in a target format, and output the optimized video image to the merger sub-circuit,
• the direct output sub-circuit is configured to directly output the received video image to the merger sub-circuit, and
• the merger sub-circuit is configured to splice the images output from the image processing sub-circuit and the direct output sub-circuit.
