Abstract
An image processing apparatus utilizing a conventional standard signal processor which is economically produced to perform processing of signals from a high-definition electronic camera. The apparatus comprises a first memory for sequentially storing input image data along a scanning line in pixel units, a control unit for sequentially reading out the image data stored in the first memory in a scanning line direction by a plurality of pixels in a vertical direction in scanning line units, a converter for converting the image data sequentially read out of the first memory into parallel image data, and a standard signal processor for performing a predetermined signal processing based on the parallel image data outputted from the converter.
Claims14
An image processing apparatus comprising:
- a first memory for storing input image data along a scanning line in pixel units;
- control means for dividing the image data stored in said first memory into a plurality of blocks, and reading out the image data blocks sequentially in block units;
- and
- a standard signal processor for performing a predetermined signal processing based on the image data read out in the block units;
- wherein said standard signal processor generates at least one of a luminance signal and color difference signals by operating on the image data sequentially read out of said first memory in a predetermined block unit.
An image processing apparatus comprising:
- a first memory for storing input image data along a scanning line in pixel units;
- control means for dividing the image data stored in said first memory into a plurality of blocks, and for reading out the image data blocks sequentially in block units;
- and
- a standard signal processor for performing a predetermined signal processing based upon the image data read out in the block units, said standard signal processor generating at least one of a luminance signal and color difference signals from image data obtained by a standard resolution electronic camera.
An image processing apparatus comprising:
- a first memory for storing input image data along a scanning line in pixel units;
- control means for dividing the image data stored in said first memory into a plurality of blocks, and for reading out the image data blocks sequentially in block units;
- and
