Image processing apparatus and image processing method

An image processing apparatus, comprising:

• an output circuit, comprising a plurality of connection ports, the output circuit being configured to perform handshakes through connected ones of the connection ports to obtain a plurality of display capability data respectively through the connected ones of the connection ports, and being configured to output a plurality of picture data through the connected ones of the connection ports respectively;
• a processing circuit, coupled with the output circuit, and the processing circuit being configured to determine a stitching mode resolution according to the display capability data;
• and
• a receiving circuit, coupled with the processing circuit, and the receiving circuit being configured to perform handshakes according to the stitching mode resolution in order to obtain a first image having the stitching mode resolution;
• wherein the processing circuit is configured to slice the first image into a plurality of sub-images corresponding to the display capability data, and is configured to generate the picture data comprising the sub-images,
• wherein each of the display capability data comprises a pose, a relative positional relationship regarding to other display devices, a size, a supported resolution, or any combination thereof of a corresponding display device,
• wherein the display capability data comprise a plurality of sizes of display devices,
• in response to a condition, determined by the processing circuit determines through the display capability data, that (1) the display devices are configured to be arranged in a matrix and the sub-images are used to form a rectangular stitched image, and (2) a height difference between a first row and a second row adjacent to each other in the matrix is higher than or equal to a height threshold, or a width difference between a first column and a second column adjacent to each other in the matrix is higher than or equal to a width threshold:
• the receiving circuit uses a non-stitching mode resolution to perform handshakes so as to obtain a second image data, wherein the second image data comprises a second image having the non-stitching mode resolution,
• the processing circuit is configured to generate the picture data respectively comprising the second image.
