     DESCRIPTION OF RELATED ART 
     With the emergence of smart phones in recent years, the demand for miniature camera lens is increasing day by day, but the photosensitive devices of general camera lens are no other than Charge Coupled Device (CCD) or Complementary metal-Oxide Semiconductor Sensor (CMOS sensor), and as the progress of the semiconductor manufacturing technology makes the pixel size of the photosensitive devices shrink, coupled with the current development trend of electronic products being that their functions should be better and their shape should be thin and small, miniature camera lens with good imaging quality therefor has become a mainstream in the market. In order to obtain better imaging quality, the lens that is traditionally equipped in mobile phone cameras adopts a three-piece or four-piece lens structure. And, with the development of technology and the increase of the diverse demands of users, and under this circumstances that the pixel area of photosensitive devices is shrinking steadily and the requirement of the system for the imaging quality is improving constantly, the five-piece, six-piece and seven-piece lens structure gradually appear in lens design. There is an urgent need for ultra-thin wide-angle camera lenses which have good optical characteristics and the chromatic aberration of which is fully corrected.

     Table 3 and table 4 show the inflexion points and the arrest point design data of the camera optical lens  10  lens in embodiment 1 of the present invention. In which, R 1  and R 2  represent respectively the object side surface and image side surface of the first lens L 1 , R 3  and R 4  represent respectively the object side surface and image side surface of the second lens L 2 , R 5  and R 6  represent respectively the object side surface and image side surface of the third lens L 3 , R 7  and R 8  represent respectively the object side surface and image side surface of the fourth lens L 4 , R 9  and R 10  represent respectively the object side surface and image side surface of the fifth lens L 5 , R 11  and R 12  represent respectively the object side surface and image side surface of the sixth lens L 6 , R 13  and R 14  represent respectively the object side surface and image side surface of the seventh lens L 7 . The data in the column named “inflexion point position” are the vertical distances from the inflexion points arranged on each lens surface to the optic axis of the camera optical lens  10 . The data in the column named “arrest point position” are the vertical distances from the arrest points arranged on each lens surface to the optic axis of the camera optical lens  10 .
