Title: Vignette image converting device
Inventor: SHIBAZAKI HIROSHI
IPC: H04N1/46
Filed: 1993-11-18
Abstract: PURPOSE:To reduce tone jumps when an image approximating a vignette is generated by generating noises of color data, in each pixel, and adding 2nd color step image data and the noises together. CONSTITUTION:This device consists of an image processing work station 30, an image data converting device 40, and an image recording device 50. A 2nd color step image is obtained by forming (N-1) figures between 1st and 2nd figures in a 1st color step image with specific step width. The step width is set sufficiently small and then differences of color data between figures in the 2nd color step image can be made sufficiently small. Further, the noises are added to the 2nd color step image to generate vignette image data. Consequently, the tone jumps at the boundaries of the figures can be made hard to become conspicuous.

Filed: 1998-11-05
Abstract: PROBLEM TO BE SOLVED: To obtain an MBS system which has a processing gain regarding MBS background noises by using a wide-band uplink signal and a narrow-band downlink signal. SOLUTION: An interrogator 103 receives a reflected and modulated signal by a receiving antenna 206, amplifies it by a low-noise amplifier 207, and demodulates the amplified signal to the intermediate frequency(IF) of a single subcarrier by using the homodyne detection of a mixer 208. An information signal 211 transmitted with the IF subcarrier is demodulated by a subcarrier demodulator 212, which sends an information signal 213 out to a processor 200 to determine message contents. Only a desired signal modulated with a pseudo-random noise code of a rate is compressed and transmitted to the processor 200. In this case, the chip rate of a pseudo-random signal is higher than the data rate of a data signal and the data rate is, for example, a bit rate or symbol rate.
