摘要： An appropriate correction quantity is obtained for a video luminance signal on an individual video basis with a characteristic value, like the maximum or average value, of the luminance signal taken into account, thereby performing gray scale correction more effectively. A dynamic gamma correction apparatus for performing a correction on a video luminance signal includes: a correction start point control section for obtaining a correction start point, which is a lower limit of a given correction range, in accordance with a characteristic value of the luminance signal; a gamma correction quantity calculating section for obtaining a provisional correction quantity for the luminance signal to be corrected using the correction start point and the luminance signal; a gamma correction gain control section for obtaining a gain for the provisional correction quantity in accordance with the characteristic value of the luminance signal; a multiplier for obtaining a product of the provisional correction quantity and the gain as a gamma correction quantity; and an adder for obtaining a sum of the luminance signal and the gamma correction quantity and outputting the sum. The correction start point and the gain for the provisional correction quantity are controllable in accordance with the characteristic value of the luminance signal. Thus, an appropriate gamma correction quantity can be obtained as a final correction quantity.

摘要： An object of the present invention is to provide a signal processor which improves the offset accuracy of a video signal without increasing the number of bits of a circuit.An N-bit adder (103) adds a video signal (S101) and an upper-N-bit signal of a brightness control signal (S102) as an offset value. A 1-bit pulse generator (107) generates a 1-bit pulse signal (S107) in which “1” and “0” have equal chances of appearing at random. A selector (106) selects the 1-bit pulse signal (S107) when the LSB of the brightness control signal (S102) is “1”, while selects a ground level “0” when the LSB is “0”, and supplies the selected signal to a carry input of the N-bit adder (103).

摘要： Providing a hot air heater and an expansion in the air blowing passage of the hot air heater and suppressing increases in air trunk resistance even if electric heaters are arranged in this expansion in a plurality of stages prevents increases in the rotation speed of the air blowing fan in order to obtain a target air flow which in turn causes the operating noise to grow louder. Therefore, an expansion 35 was formed along the air blowing passage 32. This expansion 35 has an entrance opening 351 and an exit opening 352 and functions as a storage portion that contains the electric heaters 34. The electric heaters are arranged in a plurality of stages in such a manner as to face said entrance opening and a distance between the entrance opening in the expansion and one of the electric heaters that has a highest wind speed at the entrance opening in the expansion of distances between the entrance opening in the expansion and the respective electric heaters is set farther.
