Data converting method and apparatus, and computer-readable storage medium

An image converting apparatus, comprising:

• a memory;
• and
• a processor coupled to the memory,
• wherein the memory stores computer-executable instructions which are capable of being executed by the processor to instruct the processor to:
• obtaining an original image by a processor, the original image comprising a plurality of sub-pixels arranged in a rectangle array, the plurality of sub-pixels constituting a plurality of real RGB pixels arranged in a plurality of pixel rows and a plurality of pixel columns, and each of the real RGB pixels comprising three adjacent sub-pixels in one row of the plurality of sub-pixels,
• dividing the original image into a plurality of pixel sets by the processor, wherein each of the plurality of pixel sets comprises two real RGB pixels in two adjacent pixel rows among the plurality of pixel rows and in one pixel column among the plurality of the pixel columns;
• and
• for each of the plurality of pixel sets, converting the original image into a target BV3 image by the processor, wherein the target BV3 image comprises a plurality of sub-pixels arranged in a BV3 array in which even rows of sub-pixels and odd rows of sub-pixels are staggered, the sub-pixels of the target BV3 image constitute a plurality of BV3 pixels arranged in a plurality of BV3 pixel rows and a plurality of BV3 pixel columns, each of the BV3 pixel rows comprises a first sub-pixel row and a second sub-pixel row of the target BV3 image that are adjacent to each other, and each of the BV3 pixels comprises two adjacent sub-pixels in one of a first and a second sub-pixel rows of the BV3 pixel row in which the BV3 pixel is located, and one sub-pixels in the other of the first and the second sub-pixel rows of the BV3 pixel row in which the BV3 pixel is located, the two adjacent sub-pixels and the one sub-pixels being arranged in a delta shape,
• wherein converting the original image into the target BV3 image comprises
• for each of the pixel sets, determining, by the processor, a BV3 pixel corresponding to the pixel set from a plurality of BV3 pixels;
• for each of the plurality of pixel sets, determining, by the processor, effective sub-pixels from the sub-pixels of the real RGB pixels of the pixel set according to an arrangement manner of the sub pixels of the BV3 pixel corresponding to the pixel set;
• and
• for each of the plurality of pixel sets, determining, by the processor, a pixel value of the BV3 pixel corresponding to the pixel set in the target BV3 image, based on pixel values of the effective sub-pixels determined for the pixel set.
