摘要： An all-white reference subject is imaged by a CCD and image data representing the reference subject is obtained. The position of any dust on the reference subject represented by the reference-subject image data is detected by a dust position detector. Address data representing the position of the dust is stored in a memory that stores dust address data. When the user images a subject, image data obtained by such imaging is input to a dust correction circuit. The dust address data is read from the memory and the image at the position represented by this dust address data is eliminated from the image of the subject by reason of the fact that the image at this position is that of dust.
摘要翻译：通过CCD对全白参考对象进行成像，并获得表示参考对象的图像数据。由参考对象图像数据表示的参考对象上的灰尘的位置由灰尘位置检测器检测。表示灰尘位置的地址数据被存储在存储尘埃地址数据的存储器中。当用户对被摄体进行拍摄时，通过这种成像获得的图像数据被输入到灰尘校正电路。从存储器读取灰尘地址数据，并且由于这个位置处的图像是灰尘的事实，从该灰尘地址数据表示的位置处的图像被从对象的图像中消除。

摘要： An image-capturing EV is obtained when a shutter button is half pressed, and whether to flash an electronic flash for a subject of low luminance is determined according to the image-capturing EV. If it is determined that the electronic flash should be flashed for the subject of low luminance, a white balance is adjusted according to an electronic flash light. If it is determined that the electronic flash should not be flashed for the subject of low luminance, color information relating to a plurality of areas divided from an entire image plane is acquired, and the number of areas belonging to a shade determination frame, which indicates a color distribution range corresponding to the shade, is found according to the acquired color information. Then, whether a type of the light source is the shade or the daylight is determined according to the obtained image-capturing EV and the number of areas belonging to the shade determination frame. The white balance is adjusted according to the determined type of the light source.

摘要： An object of the present invention is to bring a video signal obtained by imaging into a proper level without use of a controllable diaphragm. An imaging apparatus is provided with no controllable diaphragm. Peak detection is performed by a peak detecting circuit for each vertical scanning interval. A peak value is applied to a control device. Necessary shutter speed control in a shutter control circuit, gain control in a pre-amplifier circuit and gain control in a GCA are carried out. Consequently, the level of the video signal obtained by the imaging is adjusted to a proper level without controlling a diaphragm, to obtain an image of proper brightness.

摘要： In a digital camera in which image data produced through a photographing operation is compressed to be written in a memory card, even if a shutter release button is depressed during the recording of the image data in the memory card, the photographing can be immediately achieved. While image data stored in a buffer memory is being compressed to be stored in the memory card, the depression of shutter release button is continuously monitored. If the release button is pressed, the recording operation in the memory card is interrupted to conduct the photographing. After the photographing is finished, the image data for which the recording is interrupted is compressed to be entirely written in the memory card beginning at the start point thereof.
摘要翻译：在通过拍摄操作产生的图像数据被压缩以写入存储卡的数码相机中，即使在记录存储卡中的图像数据期间按下快门释放按钮，也可以立即实现拍摄。当存储在缓冲存储器中的图像数据被压缩以存储在存储卡中时，持续监视快门释放按钮的按下。如果按下释放按钮，则存储卡中的记录操作被中断以进行拍摄。在拍摄完成之后，将记录被中断的图像数据压缩成从其开始点全部写入存储卡。

摘要： A signal processor of an electronic still camera stores image data, obtained during photographing, into a buffer memory. A gain adjusting circuit performs multiplication on the stored image data with the exposure amount changed by 0.5 EV at a time. Next, a usage-specific processor processes the image data in one of two ways to change the gradation, contour, and so on, of the image data so that the image data may be output appropriately to a CRT or a printer.
