Image processing device and control method therefor, and storage medium

A method for controlling an image processing device that includes a buffer memory configured to temporarily store image data that is read from an image sensor at a data rate whose density varies, the method comprising:

• setting a first data rate at which the image data is transferred to a recording memory for recording the image data, according to variation in the density of the data rate;
• and
• adjusting a data rate by temporarily storing a portion of image data read from the image sensor in the buffer memory when a second data rate exceeds the first data rate, and outputting the temporarily stored portion of the image data from the buffer memory when the second data rate is lower than the first data rate, the second data rate being a data rate at which the image data is read from the image sensor, the portion of the image data corresponding to an amount by which the second data rate exceeds the first data rate.

A computer-readable storage medium in which a program for causing a computer to execute each step of a method for controlling an image processing device that includes a buffer memory configured to temporarily store image data that is read from an image sensor at a data rate whose density varies, the method comprising:

• setting a first data rate at which the image data is transferred to a recording memory for recording the image data, according to variation in the density of the data rate;
• and
• adjusting a data rate by temporarily storing a portion of image data read from the image sensor in the buffer memory when a second data rate exceeds the first data rate, and outputting the temporarily stored portion of the image data from the buffer memory when the second data rate is lower than the first data rate, the second data rate being a data rate at which the image data is read from the image sensor, the portion of the image data corresponding to an amount by which the second data rate exceeds the first data rate.
