Real Time Video Correction in NTT DoCoMo's Videophone
Fujitsu has developed real time video image quality correction technology for videophone mobile phones. If QCIF (176 x 144) resolution image data is transmitted along with voice data on a videophone call, the technology corrects image properties such as luminance and color drifts at a speed of 15 frames per second before rendering it onto the display.
The company boasts that the technology can correct videophone image quality so the receiver can see the image sufficiently, even if the background is too bright or the screen image too dark. When correcting luminance and color drifts, the technology places the focus on so-called memory colors, which particularly draw human attention, such as flesh color of human beings, green color of plants, and blue color of the sky. This technology will be used in the "F881iES," a FOMA handset to be released from NTT DoCoMo on August 19.
