Abstract
An image is picked up through sampling in a predetermined sampling pattern to acquire an image signal representing the image. Sampling information, which concerns the predetermined sampling pattern, is appended to the image signal, which has been acquired. The sampling information is information for discriminating checkered sampling and square sampling from each other. Different sharpness enhancement processing is performed on the image signal and in accordance with the sampling information to obtain a processed image signal. The different sharpness enhancement processing may be a processing in accordance with frequency characteristics of the image signal, which has been acquired, due to the sampling pattern.
Claims6
An image processing method performed by an image processing system, the method comprising:
- picking up an image, at an image acquiring device in the image processing system, through sampling in a predetermined sampling pattern to acquire an image signal representing the image, and
- appending sampling information, by the image acquiring device, which concerns the predetermined sampling pattern, to the image signal, which has been acquired,
- performing different sharpness enhancement processing at a sharpness enhancement processor on the image signal in accordance with the sampling information to obtain a processed image signal.
An image processing apparatus, comprising:
- means for picking up an image through sampling in a predetermined sampling pattern to acquire an image signal representing the image, and
- sampling information appending means for appending sampling information, which concerns the predetermined sampling pattern, to the image signal, which has been acquired,
- processing means for performing different sharpness enhancement processing on the image signal in accordance with the sampling information to obtain a processed image signal.
A computer readable medium, storing a set of instructions executed by a processor to perform an image processing method, the image processing method comprising:
- picking up an image through sampling in a predetermined sampling pattern to acquire an image signal representing the image, and
- appending sampling information, which concerns the predetermined sampling,
- performing different sharpness enhancement processing on the image signal in accordance with the sampling information to obtain a processed image signal.
