Title: Color management method
Inventor: CHOI HAN GO
IPC: H04N1/46
Filed: 1999-08-10
Abstract: PURPOSE: The color management method is provided to check the difference between the state before the color management and the state after the color management via the monitor and to keep a bold color when inputting a character. CONSTITUTION: The color management method comprises the following steps. The plotter(20) outputs a color chart(S51). The digital image, created to input the color chart via a scanner(10), is received(S52). The area and basic color of the scanned color chart are detected(S53)(S54). The detected area and color is extended to the two million color area by using the three-dimensional space interpolation(S55). The color database is made out of storing and building the replay-available color space and the index of the area(S56). After the digital image for the correction is obtained, the database is loaded and the correction area is detected(S57)(S58)(S59). In mapping the brightness of the image in the correction area, if the mapping is a fail, the luminance gamut compression achieves the mapping(S60). The color is selected from the image(S61). After determining whether the selected color can be expressible within the area or not, if no, the chrominance gamut compression is performed(S62). All the colors in the area become corrective to extract the correction color and to check the color database(S63). If all the colors are completely transformed, the color management processing ends up(65), otherwise, all the colors complete the correction to return the No.61 step(S61) again(S64). Finally, if there is a letter to input, the processing ends up after inputting the letter(S66).

Abstract: PURPOSE: An apparatus for transmitting DTMF(Dual Tone Multi Frequency) tone signals using a vocoder in a WLL(Wireless Local Loop) is provided to prevent a distortion from being generated by not executing echo cancellation, in case that a DTMF tone signal is detected by a DTMF tone signal detector. CONSTITUTION: A hybrid(110), connected with a terminal directly, makes signals transmitted and received without loss. A tone detector(120) detects a DTMF signal among the signals supplied from the hybrid(110) and outputs control signals through another path. A matching part(12) matches the signals supplied from the tone detector(120) with the signals supplied from another path. A vocoder(14) codes the signals supplied from the matching part(12) into digital signals and supplies them to an RF(Radio Frequency) transceiver(15). The RF transceiver(15) up-converts the signals supplied from the vocoder(14) into RF signals and transmits the up-converted signals to a site(200) through a connected antenna. An echo canceling part(13) extracts part of the signals outputted from the vocoder(14) and supplies the extracted signals to the matching part(12) using the signal of the phase contrary to the phase of an echo signal supplied to the matching part(12) from the tone detector(120). An on/off controller(130) controls the on/off of the echo canceling part(13) according to the control signals outputted from the tone detector(120). An adjusted detector(160) detects and outputs a distorted DTMF tone signal among the signals outputted from the vocoder(14). A DTMF tone generator(140) receives the distorted DTMF tone signal, outputs it into a normal DTMF tone signal, and supplies it to the hybrid(110). A silence generator(150) generates a silence signal by a control signal of the adjusted detector(160) for a given time in order to discriminate the normal DTMF tone signal from the next DTMF tone signal.
