The video zoom module 102 processes a paragraph one time and uses a recursive 昼 取 取 algorithm to reduce or enlarge the movie. The parameters are to select the pixels that must be retained and the scaling parameters, and then generate the interpolation function according to the scaling parameters to complete the scaling function. 1. Refer to Figure 2A and Figure 2B to illustrate the recursive painting algorithm. The graph is for the extraction of the Y component, and the u and v components are like the second β; there is the same algorithm. The 帛3 graph is the f-format of the paragraph. The data of the alizarin is the format of the YUV420. The component of the alizarin consists of two The index determines the offset and component_idx °. The following are the meanings of the parameters in the 2A and 2B graphs. pix_num is the position of a certain pixel in the φ column of 8 pixels. 仏-❿(1) is the relative original The amount of displacement of the pixel. y (L〇dd=〇 indicates that the pixels in the first row and the second row share the same “port v component, the third and fourth rows are the same” and so on. Go on. y〇_〇dd=1 means that the pixels in the first row have their own V components, and the pixels in the second and third rows share the same U and V components. The fourth and fifth rows are also The same situation, and so on. hscale_delta_frac is the ratio of interpolation. hscale-uniLdelta is the scaling parameter, the original size is divided by the size to be scaled. i nt_part represents the integer part of the relevant parameter. f rac卯忖 represents the score of the relevant parameter Part. [number] indicates the number of bits. For example, Bus[0] indicates that bi1 is not in the bus; —〇.y〇 is the component of the pixel interpolation, that is, the y after the extraction is part of the The sum of the partial 〇, u0, ul, v0, vl are also the same. Now refer to the second and second diagrams, steps 2〇1 and 21丨, the parameters required in the initial algorithm. Steps 202 and 212 are based on The scaling calculates the displacement to select the desired I test t. Step 2. 3 Α 213 Update 7 !298465 ^Plug - Desired to take the required parameters. Steps 2 and 04 and 214 determine the interpolated results added between the townships. Steps 2〇2_2〇4 and 212-214 — Repeat until the entire paragraph has been processed. The following is an example to illustrate how this algorithm works. The width of the original video window is enlarged from 24 pixels (A〇, A1, ... Α239) to 320 pixels ( B0, B1, ··· B319). Each pixel contains (Y, U, V), so A0 = (AyO, AuO, AvO), B0 = (ByO, BuO, BvO), and so on. As shown in Figure 4, the paragraph (DW) contains data from 8 AO before AO to A7. AyO is determined by DW[offsetO, y_idxO], that is, 0 bound [0,0]' gossip 4 is determined by 〇[[^^361:0, 乂-1 (1乂1], ie 01[0, 1], 其余 The rest and so on.

The hscale_unit_delta = 240/320 = 0.75, and assume the scale_init_odd = 0·

vO_byte_offset = 0 + 0 = 0, vl_byte_offset = 0;

Step 4a: Interpolation result

Byl = AyO * (1-0.75) + Ayl * 0.75 = AyO * 0.25 + Ayl * 0.75,

Bui = AuO * (1-0) + AuO * 0 = AuO,

Bvl == AvO * (1-0) + AvO * 0 = AvO; Step 2b: parameters calculation pix_shift = int_part (0.75 + 0.75) = 0? 9 1298465 u-shift = pix-shift [2:1] = 0, V_shift = pix—shift[2:l] = 0, pix_num = 0 + 1 = 1, y0_odd_num = 0 + 1 = 1;

Step 3b: parameter update hscale—delta—frac = frac_part(0.75 + 0.75) = 0.5,

Y0_idx = pix_num[2] = 0, yl_idx = y0_idx = 0, y0_byte—offset = pix_num[l :0] = 1, yl_byte—offset = 1 + 1 = 2, u0_byte—offset = 0 + 0 = 0, ul Byte—offset = 0 + 1 = 1, νθ—byte—offset = 0 + 0 = 0, vl—byte—offset = 0 + 1 = 1;

Step 4b: Interpolation result

By2 = AyO * (1-0.5) + Ayl * 0.5 = Ayl * 0.5 + Ay2 * 0.5,

Bu2 = AuO * (1-0.5) + Aul * 0.5 = AuO * 0.5 + Aul * 0.5?

Bv2 = AvO * (1-0.5) + Avl * 0.5 = AvO * 0.5 + Avl * 0.5;

Step 2c: parameters calculation pix—shift = int—part (0.5 + 0.75) = 1, u_shift = pix_shift[2:l] = 1, 10 1298465 v_shift = pix_shift[2:l] = 1, pix_num = 1 + 1 = 2, yO—odd—num = 1 + 1 = 2;

Step 3c: parameter update hscale_delta_frac = fracjpart(0.5 + 0.75) = 0.25, y0_idx = pix_num[2] = 0, yl i idx = yO_idx = 0,

Y0_byte—offset = pix_num[l :0] = 2, yl—byte—offset = 2 + 1 = 3, u0_byte_offset == 0 + 0 = 0, ul_byte_offset = u0_byte_offset = 1, vO_byte_offset = 0 + 0 = 0, Vl—byte—offset = νθ—byte—offset = 1;

Step 4c: Interpolation result

By3 = Ay2 * (1-0.25) +Ay3 * 0.25 = Ay2 * 0.75 + Ay3 * 0.25, Bu3 = Aul * (1-0.25) + Aul * 0.25 = Aul,

Bv3=Avl * (1-0.25)+Avl *0.25=Avl; According to this algorithm, the purpose of enlarging the video window can be achieved.
