Moving image conversion device

Abstract: PROBLEM TO BE SOLVED: To provide a moving image conversion device capable of enhancing the quality of a transcode picture with a small operation amount SOLUTION: The moving image conversion device is provided with a resolution conversion unit 2 which converts the resolution of a decoded image generated by an AVC decoder unit 1, and a moving vector estimation unit 3 which analyzes encoded information on a divided area of a frame extracted by the AVC decoder unit 1 to estimate a moving vector to be used to compress and encode a partial area of the decoded image whose resolution has been converted by the resolution conversion unit 2, and an AVC encoder unit 4 compresses and encodes the partial area of the decoded image using the moving vector estimated by the moving vector estimation unit 3 COPYRIGHT: (C)2009,JPO&INPIT

Image conversion method and apparatus

Abstract: Disclosed are an image conversion method and apparatus. The method for converting a two-dimensional image into a three-dimensional image using an image conversion apparatus comprises the steps of: receiving inputted depth information on an original image and setting; dividing the original image into individual parts and setting three-dimensional information for each individual part; generating a first image by moving the original image using the three-dimensional information; receiving an inputted zero point for the original image and setting; generating a second image by moving the original image using the zero point; and generating a three-dimensional image by synthesizing the first and second images. Accordingly, a still image can be converted into a three-dimensional image.

Image processing apparatus and method.

Abstract: In a color facsimile apparatus on a transmission side, color image information is encoded and stored in accordance with a parameter which optimizes the picture quality A parameter regarding the picture quality of the color image information which a color facsimile apparatus on a reception side has is recognized and compared with the parameter of the color facsimile apparatus on the transmission side In accordance with the comparison result, an image conversion of the stored color image information is executed

Theoretic research on double-CCD stereoscopic system

Abstract: A mathematical model for doubleCCD stereoscopic system was set up according to geometrical imaging principle. The relations among the distance between CCD and object, the distance between double CCDs and the distance between eyes and screen are discussed in terms of image conversion. By using these relationships, the structure design of the doubleCCD stereoscopic systems may be directed.

Image display apparatuses having a delta arrangement type screen and image conversion methods for display

Abstract: In order to reduce aliasing as much as possible in a display apparatus (100) that has a delta arrangement type screen (60), an image filter for performing a neighborhood operation is incorporated as a previous stage of a screen driving circuit (70). The image filter realizes low pass filtering including space frequency limitation in the diagonal direction that is suitable for a display on the delta arrangement type screen (60). Coefficients that constitute the filter matrix are optimised so that frequency components that exceed a Nyquist limit in the delta arrangement are suppressed. Coefficients that give optimal filter characteristics for any scale of filter matrix are defined by an expression.
