Publication number: 20110181785Abstract: A video processing apparatus includes an input unit to which a video signal containing content is input, a first detector which detects a color of light in the surroundings, a second detector which detects whether a pattern portion formed of a single color of black or white is contained in the video signal input to the input unit, a corrector which corrects the video signal input to the input unit, and a controller. The controller conducts control so that the corrector corrects the video signal input to the input unit according to the color of light detected by the first detector if the second detector detects that the pattern portion formed of the single color of black or white is contained in the video signal input to the input unit.Type: ApplicationFiled: April 8, 2011Publication date: July 28, 2011Inventors: Kozo MASUDA, Ikuya ARAI, Masaaki MIYANO

Publication number: 20110169977Abstract: The present invention evaluates the quality of an image shot by a terminal device in a state closer to that seen with the eye. A computer evaluates the quality of an image obtained by shooting a photographic subject including a periodic pattern that fluctuates periodically in one direction. A Fourier transform unit accomplishes a two-dimensional Fourier transform on the image to obtain two-dimensional spatial frequency spectrum components. An analysis unit analyzes the resolution of the image on the basis of spectrum components of spatial frequencies included in the periodic pattern, among the two-dimensional spatial frequency spectrum components obtained by the Fourier transform unit, and analyzes the deterioration of the image on the basis of spectrum components other than these.Type: ApplicationFiled: January 11, 2011Publication date: July 14, 2011Applicant: NEC CASIO MOBILE COMMUNICATIONS, LTD.Inventor: Kozo MASUDA

Publication number: 20110050994Abstract: Image deterioration when image data containing scanning lines of the previous and next fields mixed together by video editing is displayed is prevented. An inter-field scanning line interpolating unit superimposes scanning line data of the previous and next fields of interlacing image data in a video stream input from a tuner or a memory card to perform inter-field scanning line interpolation, and generates progressive image data corresponding to that video stream. An IP-conversion selection signal indicating a determination result whether or not the reliability of the video stream meets a predetermined level is input into a back-end from a CPU. A selector refers to the IP-conversion selection signal, and when the CPU determines that the reliability of the video stream is lower than the predetermined level, image data having undergone interpolation by the inter-field scanning line interpolating unit is selected as an image to be displayed.Type: ApplicationFiled: September 1, 2010Publication date: March 3, 2011Applicant: NEC CASIO MOBILE COMMUNICATIONS, LTD.Inventor: KOZO MASUDA
