摘要： PROBLEM TO BE SOLVED: To provide an imaging apparatus in which the low-luminance part of a video signal can be corrected, while suppressing the amplification of noise in the vicinity of black without generating a false profile. SOLUTION: A low-luminance region where the luminance of an input signal is between Xa and Xe, four regions in the low-luminance region, low-luminance side and high-luminance side regions in the low-luminance region, and a quadratic function representative of relation between the input signal and the output signal in each of four regions in the low-luminance region are set previously. A comparator 18 decides, to which of six regions including the four regions in the low-luminance region the luminance of an inputted video signal belongs. Based on the decision result, a selector 19 output a factor selectively. Output from an adder 14 represents a correction value and multipliers 15r, 15g and 15b multiply the input signal by the correction value to extend the luminance of the input signal and delivers the multiplication results as an output signal.

SOLUTION: At least two or more LEDs (light emitting diodes) 3 of red (R) color and those of green (G) color are respectively mounted on a side face of a cylindrical member 1 rotating with a motor 2. Light emitted from the turned on LEDs 3 is condensed on an illuminated region of an LCD (liquid crystal display) 5, modulating the light corresponding to specified image data, with a group 4 of illuminating lenses. Bright illumination is continuously applied to a surface of the LCD 5 by illuminating it while sequentially switching the LEDs 3 with rotation of the cylindrical member 1. Also in the case of switching among optically modulated states of the LCD 5 corresponding to change of color information of the image data, the illumination light is not applied during the switching period.
