Abstract
An information processing apparatus is provided which includes a buffer for holding image data output line by line from an image pickup device, a write enable generator for generating a write enable signal which indicates a timing by which the image data is written to the buffer line by line, an adder for adding per reference clock a read frequency set value which determines readout frequency of the image data written in the buffer, and a write enable generator for generating a read enable signal which indicates a timing by which the image data written in the buffer is read out line by line based on an added value of the read frequency set values.
Claims8
An information processing apparatus comprising:
- a buffer for holding image data output line by line from an image pickup device;
- a write enable generator for generating a write enable signal which indicates a timing by which the image data is written to the buffer line by line;
- an adder for adding per reference clock a read frequency set value which determines readout frequency of the image data written in the buffer;
- and
- a write enable generator for generating a read enable signal which indicates a timing by which the image data written in the buffer is read out line by line based on an added value of the read frequency set values.
A buffer control method, comprising the steps of:
- generating a write enable signal which indicates a timing by which the image data output from an image pickup device line by line is written to a buffer;
- writing the image data to the buffer line by line based on an output of the write enable signal;
- adding per reference clock a read frequency set value which determines readout frequency of the image data written in the buffer;
- generating a read enable signal which indicates a timing by which the image data written in the buffer is read out based on an added value of the read frequency set values;
- and
- reading out the image data from the buffer line by line based on an output of the read enable signal.
A computer program for causing a computer to function as the means of:
- generating a write enable signal which indicates a timing by which the image data output from an image pickup device line by line is written to a buffer;
- writing the image data to the buffer line by line based on an output of the write enable signal;
- adding a read frequency set value which determines readout frequency of the image data written in the buffer per reference clock;
- generating a read enable signal which indicates a timing by which the image data written in the buffer is read out based on an added value of the read frequency set values;
- and
- reading out the image data from the buffer line by line based on an output of the read enable signal.
