Title: Color image reader
Inventor: SEKIZAWA HIDEKAZU
IPC: H04N1/48
Filed: 1986-10-17
Abstract: PURPOSE:To reproduce visually important dark colors faithfully while suppressing the memory capacity of a color conversion circuit by providing a non-linear conversion circuit that makes the level change of input signals of low level area larger than level change in high level area in the front state of a matrix circuit. CONSTITUTION:Electric signals at every photodetecting element of a line image sensor 5 are standardized in a correcting circuit 9 from the output signals of an A/D converter corresponding to a white standard plate 10 on an original placing table 2 and the output signals of the A/D converter 8 when a light source 1 is put off, and the output signals of the correcting circuit 9 are applied to a non-linear conversion circuit 11. Level change in the low level range of input signals is made larger than that in the high level range, and the minute change of signals that indicate the component of visually important dark colors (low brightness component) is taken out as large change. Then, R, G, B signals of each picture element are converted to luminance signals Y and color difference signals C1, C2 and applied to an non-linear conversion circuit 13 and extracted signals corrected for brightness are applied to a color conversion circuit 14. Then, a color printer 15 receives an ink quantity control signal and prints the color picture of the original. Thus, faithful color reproduction is made possible.
