Abstract
In a digital still camera, it is cumbersome for the camera user to set an image photographing method and saving method of the photographed image, which are suitable for each object. When a photographing mode suitable for a moving object such as a “sports mode” is set, normal photographing is done, and the photographed image is lossless-compressed and saved. When a photographing mode suitable for a still object such as a “portrait mode” is set, a high-resolution image is captured by pixel shift photographing. The photographed image is lossy-compressed and saved.
Claims11
An imaging apparatus having an imaging unit which forms an object image, and generates an image signal by photoelectric conversion, an optical shift unit which optically shifts an imaging position of the object image in said imaging unit, a generation unit which generates a single image from a plurality of images obtained by said imaging unit by a plurality of shifts using said optical shift unit, and a storage unit which converts an image obtained by said image unit or the image generated by said generation unit into a predetermined data format, and stores the converted image in a storage medium, said apparatus comprising:
- a detection unit which detects spatial frequency characteristics of the image signal obtained by said imaging unit;
- and
- a control unit which sets the data format and controls supply of an image to said storage unit in correspondence with the detected spatial frequency characteristics.
An imaging method of an imaging apparatus having an imaging unit which forms an object image, and generates an image signal by photoelectric conversion, an optical shift unit which optically shifts an imaging position of the object image in the imaging unit, a generation unit which generates a single image from a plurality of images obtained by the imaging unit by a plurality of shifts using the optical shift unit, and a storage unit which converts an image obtained by the imaging unit or the image generated by the generation unit into a predetermined data format, and stores the converted image in a storage medium, the method comprising the steps of:
- detecting spatial frequency characteristics of the image signal obtained by the imaging unit;
- and
