    • A camera apparatus equipped with an optical system, a photographing element for converting a light signal of an object to be photographed from the optical system to an electric signal, an A/D conversion unit for converting the electric signal from the photographing element to digital image data, a data compression unit for compressing the image data from the A/D conversion unit with a prescribed form based on a software program. Data conversion converts the compressed data from the data compression unit to a prescribed form of data that is recordable into a direct read after write type optical disk or a rewritable optical disk that records the compressed data. The camera enables a user to watch on a personal computer static images that have been photographed without making data transfer to the personal computer.

    • An image signal processing unit comprising an image signal receiver, a first addition block, a compression block, and a determination block, is provided. The image signal receiver receives an image signal. The image signal is generated by an imaging device. The imaging device has a plurality of pixels generating pixel signal. A receiving surface of the imaging device is divided into a number of pixel blocks. A number of pixels are arranged in the pixel block. The first addition block generates high-sensitivity signal by adding up the pixel signals generated by some pixels arranged at a predetermined position in the pixel block. The compression block generates low-sensitivity signal by compressing the high-sensitivity signal so that the low-sensitivity signal is lower than the maximum signal level of the pixel signal. The determination block determines whether a signal level of the high-sensitivity signal is over the threshold level The low-sensitivity signal is output if the signal level of the high-sensitivity signal is over the threshold level. Alternatively, the high-sensitivity signal is output if the signal level of the high-sensitivity signal is under the threshold level.
    • 提供了包括图像信号接收器,第一加法器块,压缩块和确定块的图像信号处理单元。 图像信号接收器接收图像信号。 图像信号由成像装置产生。 成像装置具有产生像素信号的多个像素。 成像装置的接收表面被分成多个像素块。 像素块中排列有多个像素。 第一加法器块通过将排列在像素块中的预定位置处的一些像素生成的像素信号相加来生成高灵敏度信号。 压缩块通过压缩高灵敏度信号来产生低灵敏度信号,使得低灵敏度信号低于像素信号的最大信号电平。 确定块确定高灵敏度信号的信号电平是否超过阈值电平如果高灵敏度信号的信号电平超过阈值电平,则输出低灵敏度信号。 或者,如果高灵敏度信号的信号电平低于阈值电平,则输出高灵敏度信号。

    • A recording operation control device comprises a recording operation stop switch on a rear surface of a camera body of an electronic still camera. By fully depressing a shutter button, a CCD housed in the camera body is exposed so that image data is obtained and recorded in a PC card. If the recording operation stop switch is depressed before the recording operation of the image data is completed, the recording operation is stopped. Instead of depression of the recording operation stop switch, the shutter button may be depressed twice during a constant period of time so that the recording operation is stopped. Both the recording operation stop switch and the shutter button may be depressed to stop the recording operation.
    • 记录操作控制装置包括在电子静态照相机的照相机主体的后表面上的记录操作停止开关。 通过完全按下快门按钮,曝光在相机机体中的CCD,从而获得图像数据并将其记录在PC卡中。 如果在图像数据的记录操作完成之前按下记录操作停止开关,则停止记录操作。 代替按下记录操作停止开关,可以在恒定时间段期间按下快门按钮两次,从而停止记录操作。 可以按下记录操作停止开关和快门按钮以停止记录操作。
