Abstract:
An interface apparatus of an image processing system includes an image sensor sensing an image, an image processor processing the sensed image to output image data, and a sensor interface coupled between the image sensor and the image processor. The sensor interface includes a sensor type register storing information about the image sensor, a micom storing the information in the sensor type register to control the image sensor, and a sensor signal processor receiving signals corresponding to the sensed image from the image sensor, converting the signals into modified signals, which the image processor processes to output the image data, according to the information stored in the sensor type register, and transmitting the modified signals to the image processor. The interface apparatus used in the image processing system, such as a digital camera, adaptively correspond to the image sensor which is currently used in the image processing system and has one of different types of image sensors, according to the manufacturers and product models of the image sensors. The interface apparatus adaptively processes signals outputted from the image sensor, thereby avoiding any additional redesigning process of redesigning the image processor to correspond to the image sensor used in the image processing system, and reducing a manufacturing time and cost of the image processing system.
Abstract:
A line buffer and a method of providing data to a 3null3 line interpolation processor using the line buffer in an image processing system, such as a digital camera, includes a readable and writable single memory, a buffer register having a prior data area storing first line image data, which has been stored in a memory, in a unit of 2m bits, and having a present data area storing second image data, which is inputted from an image sensor in a unit of m bits, in a unit of the 2m bits, and a memory controller providing the memory with a chip enable signal, a write enable signal, and an address indicating locations of the first and second line image data stored in the buffer register, reading and writing the first and second line image data from and on the memory, and outputting the first and second line image data and a third line image data, which is inputted from the image sensor.
