Photographing apparatus with two image sensors of different size

A photographing apparatus, comprising;

• a photographing lens;
• a first image pick-up device having a first light-receiving unit and for photoelectrically converting an optical image of an object formed by the photographing lens into first pixel data;
• a second image pick-up device having a second light-receiving unit and for photoelectrically converting an optical image of the object formed by the photographing lens into second pixel data, the size of the second light-receiving unit being different from the size of the first light-receiving unit;
• and
• a relay lens system positioned before the first image pick-up device and for focussing the optical image of the object onto the first image pick-up device,
• wherein a ratio of the composite focal length of the photographing lens and the relay lens system to a size of the first light-receiving unit being equal to a ratio of the focal length of the photographing lens to a size of the second light-receiving unit.

A photographing apparatus, comprising:

• a photographing lens;
• a first image pick-up device having a plurality of pixels and for photoelectrically converting an optical image of an object formed by the photographing lens into first pixel data;
• a second image pick-up device having a plurality of pixels and for photoelectrically converting an optical image of the object formed by the photographing lens into second pixel data, the number of pixels of the second image pick-up device being greater than the number of pixels of the first image pick-up device;
• a display for displaying the first pixel data supplied from the first image pick-up device as a preview image prior to image recording;
• a first processor for processing the first pixel data supplied from the first image pick-up device;
• and
• a second processor for processing the second pixel data supplied from the second image pick-up device, wherein only the first processor adjusts white balance.

• a processor for combining a part of the first pixel data obtained by the first image pick-up device with a part of the second pixel data obtained by the second image pick-up device to produce a composite image;
• and
• a display for displaying the composite image produced by the processor as a preview image prior to image recording.

A photographing apparatus, comprising:

• a photographing lens;
• a first area sensor having a plurality of pixels and for photoelectrically converting an optical image of an object formed by the photographing lens into first pixel data;
• a second area sensor having a plurality of pixels and for photoelectrically converting an optical image of the object formed by the photographing lens into second pixel data, the number of pixels of the second area sensor being greater than the number of pixels of the first area sensor, and a size of the second area sensor being larger than a size of the first area sensor;
• a display for displaying the first pixel data supplied from the first area sensor as a preview image prior to image recording;
• and
• a recorder for recording the second pixel data supplied from the second area sensor in a recording medium.
