2.3.3 Moving Picture Mode
The size of a compressed data file in each frame is restricted by the segment size specification. For the segment
size, any of 256/512/1K/2K/4K/8K/16K/32K/64K bytes can be selected according to the image size.
(Be careful so that the compressed data file size does not exceed the segment size.)
The addresses of compressed data files are managed using index pointers.
An index pointer is 16 bits in size, and indicates the number of a frame to be compressed or decompressed. A
frame number is equivalent to the upper bit of the start address of a compressed data file. An actual address is
a value that is shifted to the left by the number of bits for the segment size.
An index pointer is a sort of a counter.
When recording moving pictures, the value of an index pointer is incremented from 0 to the specified number
of frames for each input frame.
When playing back moving pictures, various playback operations can be performed, such as “normal play” that
increments an index pointer for each display frame, “reverse play” that decrements an index pointer, “slow
play” that increments an index pointer for 2/4/8/15/30/60 display frames, and "fast forward play" that skips an
index pointer at intervals of specified numbers.
One or two locations can be specified as the source image read addresses when compressing and playback
image write addresses when decompressing.
If two locations are specified at the same time, they can
alternately be switched for each frame. When playing back moving pictures, a double-buffer operation can be
performed, achieving smooth moving picture display.
