摘要： PROBLEM TO BE SOLVED: To provide an imaging apparatus which performs imaging in such a way that an excellent resolution conversion result can be obtained even when improving a resolution through resolution conversion during playback. SOLUTION: An imaging apparatus discriminates an image frame to extract as a reference image from a plurality of image frames constituting a moving image, using a histogram, for example, and generates a reference image data file with a reference image extracting unit 105. An encoder unit 108 encodes the plurality of image frames after reducing the resolution thereof, and generates an encoded moving image data file. A list in which an image frame corresponding to the reference image data file in the encoded moving image data file is associated with information specifying the corresponding reference image data file, is generated with a content information list generation unit 107. The reference image data file, the encoded moving image data file and the list are then recorded in a first storage unit. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PURPOSE:To apply interpolation without causing deterioration in picture quality even if a picture is moved in various directions by obtaining the total sum of products between an adaptive interpolation coefficient and an interpolation value in each direction and using the total sum as a picture element value to be interpolated. CONSTITUTION:An input picture signal sampled is sequentially stored in frame memories 1, 2, picture element values A, B, C, D among A, B, C, D, E, F used for adaptive interpolation are read from the memory 1, the E is read from the memory 2 and the F is read without being stored in the memory, and inputted to a weight calculation section 3 and an interpolation value calculation section 4. The calculation section calculates weights Pn, Pv and Pt. The calculation section 4 calculates 1/2(A+B), 1/2(C+D) and 1/2(E+F) from input picture element values A-F. After the output of the calculation section 4 is multiplied respectively with the weights Pn, Pv, Pt at multipliers 5, 6, 7, the result is added by adders 8, 9 to form the final adaptive interpolation outputs.

摘要： PURPOSE:To decrease the flickering of a standstill part of screen at low speed shot coding mode by discriminating the degree of movement to a picture subjected to low speed shot and applying a replaced reproducing picture when the movement is small and applying an interpolated reproducing picture when the movement is large. CONSTITUTION:A selector 13 outputs an original picture signal at an odd number field and outputs a reproducing picture fed from a selector 12 at an even number field subjected to low speed shot. In the reproducing picture of the 2nd even number field screen 17 subjected to the low speed shot, the intepolated reproducing picture decides the replaced reproducing picture depending on the difference among the part (picture element) corresponding to the 1st and 3rd, odd number field screen field screens 15, 16 before and after the screen 17. For example, when the difference among the picture element b' of the 2nd even number field screen 17 and picture elements b, b'' corresponding to the 1st and 3rd odd number field screens and also the picture elements a, a'' and c, c'' before and after the screen 17 is all a threshold value or below to determine the dynamic picture and the still picture, it is regarded as an element with less dynamic element to obtain a replaced reproducing picture. In other cases, the interpolated reproducing picture is obtained.
