    • According to one embodiment, an edge detection module detects edges in a frame of a moving picture signal in accordance with an edge determination reference value. A resolution conversion module converts a resolution of the frame from a first resolution to a second resolution, thereby generating a provisional high-resolution image. A corresponding pixel point detection module detects corresponding pixels in the provisional high-resolution image, which correspond to each of the detected edges. An image quality enhancement process module executes an image quality enhancement process for sharpening for each of the detected corresponding pixels in the provisional high-resolution image. A control module varies the edge determination reference value based on the detected edge number and a maximum edge number at which an information processing apparatus is able to complete the resolution-enhancing process for one frame within a target process time.

    • The viscosity of a puncture-preventing sealant (7) is set in a range of 25 to 35 dPa·s, and a thixotropy index is set in a range of 6.5 to 11.0, the sealant (7) being filled in a sealant chamber (6) defined to extend along an outer periphery of an air chamber (5) in a tire (T). When the tire (T) is being rotated by traveling of a vehicle, the viscosity of the sealant (7) is reduced by a stirring action provided by a vibration or a centrifugal force of the sealant (7), whereby the sealant (7) can be diffused uniformly in the sealant chamber (6). When the vehicle has been stopped and the stirring action has been extinguished, the viscosity of the sealant (7) is increased, whereby the sealant (7) is maintained in a state in which it has been diffused uniformly in the sealant chamber (6) without flowing downwards in the sealant chamber (6) by gravitation. Therefore, even when the vehicle is travelling at a high speed, the generation of a vibration and a noise can be prevented. In this manner, the puncture-preventing sealant is provided, which has such a nature that the sealant is easy to flow due to a low viscosity during traveling of a vehicle, and the sealant is difficult to flow due to a high viscosity when the sealant is left to stand.
    • 防刺破密封剂(7)的粘度设定在25〜35dPa.s的范围内,触变性指数设定在6.5〜11.0的范围内,密封剂(7)填充在密封剂室( 6)限定为沿着轮胎(T)中的空气室(5)的外周延伸。 当轮胎(T)通过车辆行驶而旋转时,通过由密封剂(7)的振动或离心力提供的搅拌作用,密封剂(7)的粘度降低,由此密封剂(7) 可以均匀地扩散到密封剂室(6)中。 当车辆停止并且搅拌动作已经熄灭时,密封剂(7)的粘度增加,由此密封剂(7)保持在均匀地扩散到密封剂室(6)中的状态, 而不会通过重力在密封剂室(6)中向下流动。 因此,即使当车辆高速行驶时,也可以防止产生振动和噪音。 以这种方式,提供了防止穿刺的密封剂,其具有这样的性质,即当车辆行驶期间由于粘度低时,密封剂容易流动,并且当密封剂的粘度高时,密封剂难以流动 留下来
