    • A solid state image pickup element includes a pixel unit having a plurality of pixels for photoelectric conversion disposed in a matrix shape and a pixel signal read circuit for reading pixel signals in the unit of a plurality of pixels from the pixel unit. The pixel signal read circuit includes a plurality of comparators disposed in correspondence with a pixel column layout for performing comparison judgment between a read signal potential and a reference voltage and outputting a judgment signal and a plurality of counters each for counting a comparison time of a corresponding one of the comparators, an operation being controlled by an output from a corresponding one of the comparators. The comparators include a first amplifier for performing a comparison operation between the reference voltage and the read signal potential and inverting an output at a predetermined comparison point, a second amplifier for forming a current path when an output of the first amplifier is inverted, to output an output of the first amplifier by gain up, and a current control circuit for shutting the current path of the second amplifier when an output level of the second amplifier exceeds a predetermined threshold level.

    • An image-retransfer sheet for receiving an image and for retransferring the received image onto a desired image-receiving material. The image-retransfer sheet includes a substrate and a surface layer formed of surface treating agent and coated on one surface of the substrate for defining an image-receiving surface. The surface layer is provided with adhesive force control matter for controlling adhesive force to be imparted from the image-receiving surface of the surface layer. The adhesive force control matter may be provided on the surface layer in the form of a layer coated on the surface layer. Or otherwise, the adhesive force control matter may include polyethylene fine powders mixed with the surface treating agent in the surface layer. The adhesive force control matter thus provided in the image-retransfer sheet serves to control the adhesive force to such a value that only a part of the surface layer receiving the image thereon may be retransferred onto the image-receiving material together with the image.
    • 一种用于接收图像并将接收到的图像重新传送到期望的图像接收材料上的图像再转印纸。 图像再转印片材包括基材和由表面处理剂形成的表面层,并涂覆在基材的一个表面上,用于限定图像接收表面。 表面层设置有用于控制从表面层的图像接收表面施加的粘合力的粘合力控制物质。 粘合力控制物质可以以涂层在表面层上的层的形式提供在表面层上。 否则,粘合力控制物质可以包括与表面层中的表面处理剂混合的聚乙烯细粉末。 因此在图像再转印片中提供的粘合力控制物质用于将粘合力控制到这样一个值,使得只有其上接收图像的表面层的一部分可以与图像一起转印到图像接收材料上。
