-obtain the memory block of an a2*b2, be used for the pixel value of storage pixel point, wherein, the difference of a2 and a1 equals b1 more than or equal to 1, b2;
Described view data is read in reading method and is also comprised step:
1) when the memory block of this a2*b2 is begun to store a1*b1 pixel value and this a1*b1 pixel value and also do not read by first address, makes the first row of the first row of the memory block of first this a2*b2 of pointed;
2) begin sequentially to read a1*b1 pixel value for use in demonstration by the current position pointed of described the first pointer, and make the next column when the prostatitis of the memory block the first row of described first this a2*b2 of pointed;
3) after reading a1*b1 pixel value, the pixel value of the row pixel that the current scanning of described line sweep imaging device is obtained reads in the previous column of row of the current sensing of described the first pointer, wherein, pixel value reads in from the second row of the previous column of the row of the current sensing of described the first pointer;
4) repeating step 2) and 3), until last row of the first row of the memory block of described first this a2*b2 of pointed.
6. the view data for the line sweep imaging device as claimed in claim 5 is read in reading method, characterized by further comprising step:
-obtain the memory block of an a3*b3, be used for the pixel value of storage pixel point, wherein, the difference of a3 and a1 equals b1 more than or equal to 1, b3;
Described view data is read in reading method and is also comprised step:
-make the first row of the first row of the memory block of second this a3*b3 of pointed;
Described step 3) also comprises step:
The pixel value of-a row pixel that the current scanning of described line sweep imaging device is obtained reads in the row of the current sensing of described the second pointer, wherein, and the reading in from the first row of the row of the current sensing of described the second pointer of pixel value; And
-make described second this a3*b3 of pointed the memory block the first row when the next column in prostatitis;
After step 4), also comprise step:
5) sequentially read a1*b1 pixel value for use in demonstration by last row beginning of the current the first row pointed of described the first pointer, and after reading a1*b1 pixel value, the pixel value of the row pixel that the current scanning of described line sweep imaging device is obtained reads in the current row pointed of described the second pointer, wherein, pixel value read in from the row of the current sensing of described the second pointer the first row begin sequentially to carry out; And
6) make the first row of the memory block the first row of the described a3*b3 of the first pointed, make the first row of the memory block the first row of the described a2*b2 of the second pointed.
