Abstract
According to the present invention, a reduced image is generated only from one of high-sensitivity image information or low-sensitivity image information when RAW data is recorded, and the reduced image is recorded on a recording medium together with the RAW data (first and second RAW data). Thereby, it is possible to create the reduced image in a relatively short time. In this case, if a reduced image is generated from the high-sensitivity image information, a high-contrast image with a desirable S/N ratio can be acquired. If a reduced image is generated from the low-sensitivity image information, an image appropriately representing the content of a reproduction area of the RAW data can be acquired.
Claims9
An imaging apparatus, comprising:
- a first imaging device which takes an image of an object under imaging conditions with relatively high sensitivity to acquire high-sensitivity image information;
- a second imaging device which takes an image of an object under imaging conditions with relatively low sensitivity to acquire low-sensitivity image information;
- a reduced image generation device which generates a reduced image only from one of the high-sensitivity image information acquired by the first imaging device or the low-sensitivity image information acquired by the second imaging device;
- and
- a recording processing device which records first RAW data indicating the high-sensitivity image information acquired by the first imaging device, second RAW data indicating the low-sensitivity image information acquired by the second imaging device and the reduced image data generated by the reduced image generation device in association with one another.
An image recording method, comprising:
- a first imaging process which takes an image of an object under imaging conditions with relatively high sensitivity to acquire high-sensitivity image information;
- a second imaging process which takes an image of an object under imaging conditions with relatively low sensitivity to acquire low-sensitivity image information;
- a reduced image generation process which generates a reduced image only from one of the high-sensitivity image information acquired by the first imaging process and the low-sensitivity image information acquired by the second imaging process;
- and
- a recording processing process which records first RAW data indicating the high-sensitivity image information acquired by the first imaging process, second RAW data indicating the low-sensitivity image information acquired by the second imaging process and the reduced image data generated by the reduced image generation process in association with one another.
