  • Publication number: 20080284878
    Abstract: The present invention relates to an image processing apparatus, method, and program which compress images so as to improve contrast without losing sharpness. An adder 33 calculates an illumination-component addition/subtraction remaining amount T (L) by an adder 25 to a multiplier 32. An adder 34 adds T (L) to an original illumination component, and calculates a gain-optimum illumination component T (L)?. An aperture controller 23 performs aperture correction which is dependent on an illumination-component level on the basis of an adaptation area determined by a reflectance-gain coefficient calculation section 35. An adder 37 adds T (L)? to the texture component after the aperture correction. Thus, a luminance signal Y2 after dynamic-range compression is obtained. An HPF 41 to an adder 43 perform LPF processing on a chroma signal of a low-band level portion. Thus, a chroma signal C2 after the dynamic-range compression is obtained. The present invention can be applied to a digital video camera.

  • Publication number: 20080153236
    Abstract: Flash memory devices and methods for fabricating the same are provided. A method for fabricating a memory device comprises the steps of fabricating a first gate stack and a second gate stack overlying a P-type silicon substrate and implanting an impurity dopant into the substrate substantially between the first gate stack and the second gate stack to form an impurity-doped region of the substrate. A channel region underlies the first gate stack adjacent to the impurity-doped region. An intrinsically tensile-stressed insulating member is formed between the first and the second gate stacks and overlying the impurity-doped region. The tensile-stressed insulating member causes a uniaxial lateral tensile stress to be transmitted to the first channel region. A word line is formed overlying the intrinsically tensile-stressed insulating member and in electrical contact with the first gate stack and the second gate stack.

The substrate 1 is permitted cleaving and splitting along a (10-10) plane 4 with ease. Using this substrate to form a semiconductor laser diode of a nitride compound, a vertical structure device can be realized. Resonant planes of a semiconductor laser diode with a minimum of loss can be fabricated by splitting the device in a direction parallel to the (10-10) plane. A method of manufacture that eliminates a margin of cutting is also realized.
