Abstract
An image signal processor includes a shared circuit, a first circuit, and a second circuit. The shared circuit processes input image data. The first circuit provides a first algorithm for processing the input image data and is used by the shared circuit to process the input image data at a first operation mode in a first shooting environment. The second circuit provides a second algorithm for processing the input image data and is used by the shared circuit to process the input image data at a second operation mode different from the first operation mode in a second shooting environment different from the first shooting environment.
Claims22
An image signal processor, comprising:
- a shared circuit which processes input image data;
- a first circuit that provides, to the shared circuit, a first algorithm which is used by the shared circuit to process the input image data at a first operation mode in a first shooting environment;
- and
- a second circuit that provides, to the shared circuit, a second algorithm which is used by the shared circuit to process the input image data at a second operation mode different from the first operation mode in a second shooting environment different from the first shooting environment.
10-12. (canceled)
An image processing system, comprising:
- an image signal processor which includes a shared circuit configured to process input image data, and a plurality of algorithmic circuits configured to provide to the shared circuit algorithms which are used to process the input image data in different operation modes depending on a shooting environment;
- and
- a mode deciding module which detects the shooting environment based on information provided from an image sensor or an ambient light sensor and which decides an operation mode of the image signal processor as a decided operation mode.
15-23. (canceled)
An operating method of an image signal processor, comprising:
- setting an operation mode for processing input image data;
- selecting first format image data provided from an image sensor as the input image data, when the operation mode is a first operation mode;
- selecting second format image data provided from the image sensor as the input image data, when the operation mode is a second operation mode different from the first operation mode;
- processing the input image data, using a first circuit which provides a first algorithm for processing the input image data, when the operation mode is the first operation mode;
- and
- processing the input image data, using a second circuit which provides a second algorithm for processing the input image data, when the operation mode is the second operation mode.
