    摘要: Photographing for one image plane is conducted by CCD1 under the completely dark condition created by closing aperture 12 when the power supply is turned on, then image data obtained from this photographing are compared with a threshold value, and when the image data show higher luminance than the threshold value, the image data are detected to be defective pixels (white flaws) and positional information thereof is stored. Further, under the condition that the mode for detecting defective pixels is selected by mode switch 16, photographing for one image plane is conducted by CCD1 while a camera is directed to an exclusive subject, then image data obtained through this photographing are compared with a threshold value, and when the image data show lower luminance than the threshold value, the image data are detected to be defective pixels (black flaws), and positional information thereof is stored. In ordinary photographing, a mean value of peripheral pixels surrounding the image data of the defective pixel is used for replacement based on positional information of the defective pixel.

    摘要: Since a delaying part (14) delays transmission of a video signal, the timing at which a decoded video signal is input into a multiplex processing part (16) matches the timing at which an analysis result from an encoded information analyzing part 13 is received by the multiplex processing part (16). It is, therefore, possible to perform processing for showing the quality level of a video on the same screen, and thus a large capacity memory is unnecessary.

    摘要: An image processing method for an electronic camera which includes a photoelectric element having plural sensors and color filters in plural different colors, wherein each of the plural sensors corresponds to a respective one of the color filters in the different colors. The method includes the steps of: obtaining a signal value from a target sensor of the sensors when one of the sensors is assigned to the target sensor; obtaining the first average value from signal values of the sensors having the color filters of which a color is the same as that of the color filter of the target sensor; obtaining the second average value from signal values of the sensors having the color filters of which a color is different from that of the color filter of the target sensor; and obtaining an interpolation value for a color, which is different from that of the color filter of the target sensor, of the target sensor according to the signal value from the target sensor, the first average value and the second average value.
