Photographing apparatus and photographing method

A photographing apparatus of interlace transferring type comprising:

• a photographing device which carries out transfer of electrification of all pixels stored in the photographing device by dividing into a plurality of fields when transferring the electrification and which has a plurality of color filters and which includes a color signal of at least RGB or YeCyMgG in said transfer data of each field for transferring said electrification;
• extraction means for extracting characteristic data of image from transferred data before processing for image is started;
• generating means for generating control value carrying out correction of image based on said extracted characteristic data;
• image processing means for processing image by use of control value formed by said characteristic data;
• and
• selection means for selecting either a first mode for processing and recording the transfer data of all pixels accumulated in said photographing device or a second mode for processing and recording transfer data of pixels less than said all pixels, wherein in said second mode selected by said selection means, later transferred data is processed and recorded by the control value generated by said characteristic data extracted from the previously transferred data with division of the plurality of fields.

A photographing method of interlace transferring type comprising the steps of:

• dividing data transfer of electrification of all pixels stored in an photographing device of interlace transferring type into a plurality of fields when transferring the electrification;
• providing a plurality of color filters in said photographing device;
• receiving transfer data from said image element which transfers data including a color signal of at least RGB or YeCyMgG to each field;
• extracting characteristic data of image from the transferred data;
• and generating a control value of effecting correction of image based on the extracted characteristic data to make image processing using said control value.

A photographing method comprising the steps of:

• preparing a solid photographing device which has a plurality of pixels compartmentalized in every predetermined regions and in which a pixel for detecting a pixel value of each color of three original colors through a color filter of said plurality of pixels is arranged in said regions, said photographing device being determined so that a defecting pixel for generating a white scratch of temperature which changes according to temperature is one or less in each region, each pixel value of all the pixels in the solid photographing device being read out with division of fields of three or more to form an image of one frame based on the read out pixel value;
• obtaining a difference about the pixel value among the pixels at arranged positions corresponding to first and second fields detected through color filters of the mutually same color arrangement every said regions;
• and
• judging that when a difference between two pixels exceed a predetermined threshold, one pixel of the two is the defecting pixel and for amending a pixel value of the one pixel based on a pixel value of the other pixel of the two.

A photographing apparatus comprising:

• a photographing device having a color filter for resolving color:
• imaging means for focusing an image to be photographed on said photographing device;
• a photographing processing section for converting to digital signal electrification stored in said photographing device and transferred;
• and
• means for carrying out image processing including at least YUV conversion by use of transfer data transferred through said imaging processing part, wherein said photographing device is interlace transferring type and divides data transfer of electrification of stored all pixels into M(≧3) fields.
