Image processing apparatus and image processing method |
摘要 |
An image processing apparatus and an image processing method are provided. When a display apparatus is in the 3D display mode, a mode-switching unit adjusts the way to generate a vertical-count-value by counting every two rows of pixels and outputs the adjusted vertical-count-value. A dither unit outputs a carry value corresponding to the adjusted vertical-count-value. An adding unit adds the carry value and the surplus pixel bit together. |

1. An image processing method for adjusting a gray level of a pixel block of a display apparatus, an image being displayed on the pixel block by switching a plurality of frames, the image processing method comprising:
acquiring a least significant bit and a surplus pixel bit from each pixel of the pixel block, wherein the surplus pixel bit is the bit in each pixel other than the least significant bit; determining whether the display apparatus is in a three-dimensional display mode or in a two-dimensional display mode according to a mode-switching signal; if the display apparatus is in the three-dimensional display mode, adjusting a way to generate a vertical-count-value by counting every two rows of pixels, wherein the least significant bit indicates a dither matrix group corresponding to the pixel block, and the vertical-count-value indicates a carry value of the dither matrix group corresponding to each row of pixels of the pixel block, wherein the vertical-count-value is a positive integer, the vertical-count-value corresponds to a position of the pixel block where the surplus pixel bit is generated from; outputting the carry value corresponding to the vertical-count-value; and adding the carry value of the dither matrix group corresponding to the vertical-count-value to the surplus pixel bit corresponding to the vertical-count-value. |
