    • In an image pickup apparatus, a level compensator compensates the level of an image xL (i, j) sensed by an image sensor by exposure for a long time on the basis of the exposure of the image to produce a compensated image xL′ (i, j), while another level compensator compensates the level of an image xS (i, j) sensed by the image sensor by exposure for a short time on the basis of the exposure of the image to produce a compensated image xS′ (i, j). The image pickup apparatus also includes an image synthesizer to synthesize these compensates images xL′ (i, j) and xS′ (i, j) to produce a single synthetic image x (i, j). A dynamic range compressor also included in the image pickup apparatus compresses the synthetic image x (i, j) to produce a compressed image y (i, j) for delivery to outside.
    • 在图像拾取装置中,电平补偿器基于图像的曝光来补偿由图像传感器感测的图像xL(i,j)的电平,以产生补偿图像xL'(i ,j),而另一个电平补偿器基于图像的曝光补偿由图像传感器感测到的图像xS(i,j)的电平,以产生补偿图像xS'(i,j) j)。 图像拾取装置还包括用于合成这些补偿图像xL'(i,j)和xS'(i,j)以产生单个合成图像x(i,j)的图像合成器。 还包括在图像拾取装置中的动态范围压缩器压缩合成图像x(i,j)以产生用于传送到外部的压缩图像y(i,j)。

    • An image signal generation portion 11 generates an image signal of a variable frame-rate picked-up image. A signal generation control portion 24 drives the image signal generation portion 11 and generates image pick-up setting information IF to generate an image signal that is frame-synchronized with a generated image signal DVd. The generated image signal DVd is output in condition where the image pick-up setting information IF is inserted in it. When supplied with image pick-up setting information IFex, the signal generation control portion 24 controls the driving operations of the image signal generation portion 11 based on the image pick-up setting information IFex, to frame-synchronize the generated image signal with an image signal of a reference variable frame-rate picked-up image of a source that has supplied the image pick-up setting information IFex. If a plurality of image pick-up devices capable of varying a frame rate is used, the image signals can be frame-synchronized with each other.
    • 图像信号生成部分11生成可变帧率拍摄图像的图像信号。 信号发生控制部分24驱动图像信号产生部分11并产生图像拾取设置信息IF以产生与产生的图像信号DVd进行帧同步的图像信号。 在其中插入图像拾取设置信息IF的条件下输出所生成的图像信号DVd。 当提供图像拾取设置信息IFex时,信号产生控制部分24基于图像拾取设置信息IFex控制图像信号生成部分11的驱动操作,以使图像信号与图像同步 提供图像拾取设置信息IFex的源的参考可变帧速率拾取图像的信号。 如果使用能够改变帧速率的多个图像拾取装置,则图像信号可以彼此帧同步。
