    • According to the present invention, there is provided an aluminum nitride sintered body having a high thermal conductivity and essentially consisting of a AlN single-phase, containing 0.01 to 8,000 ppm of rare earth elements and less than 2,000 ppm of oxygen. According to the present invention, there is provided a method of fabricating an aluminum nitride sintered body having a high thermal conductivity and essentially consisting of AlN single-phase, containing 0.01 to 8,000 ppm of rare earth elements and less than 2,000 ppm of oxygen, wherein a molded body prepared by mixing and molding an aluminum nitride power having less than 7 wt % of oxygen and an average particle size of 0.05 to 5 .mu.m and with rare earth compounds of 0.01 to 15 wt % of based on rare earth elements content, or a sintered AlN body containing oxide grain boundary phases of 0.01 to 15 wt % of rare earth elements and 0.01 to 20 wt % of oxygen and (rare earth element)--Al--O compounds phases and/or (rare earth element)--O compounds phases, is fired in a reducing atmosphere at a temperature of 1,550 to 2,050.degree. C. for 4 hours or more.

    • There is provided an image taking apparatus capable of preferably correcting both the camera shake and the subject shake in the still picture photography. The image taking apparatus has a system control section that determines whether a subject is a still subject or a dynamic subject. When the system control section determines that the subject is the still subject, the system control section instructs a timing generation section to cause an imaging section to generate a series of images, so that an image piling up section performs piling up of images in accordance with a computed result with a movement vector computing section. Thus, the camera shake is corrected. When the system control section determines that the subject is the dynamic subject, the system control section instructs the timing generation section to perform a single photography at a predetermined shutter time free from the subject shake.
    • 提供了一种能够在静态图像拍摄中优化校正相机抖动和被摄体抖动的图像拍摄装置。 图像摄取装置具有确定被摄体是静止被摄体还是动态被摄体的系统控制部。 当系统控制部分确定主体是静止对象时,系统控制部分指示定时生成部分使得成像部分生成一系列图像,使得图像打桩部分根据图像进行堆叠 运动矢量计算部分的计算结果。 因此,校正相机抖动。 当系统控制部分确定被摄体是动态对象时,系统控制部分指示定时生成部分在没有被摄体抖动的预定快门时间进行单次拍摄。
