Problems solved by technology

[0004] Therefore, if the difference in the transfer speed of the image data cannot be fully compensated, an overshoot phenomenon of the image data called tearing occurs in which the incomplete image data stored in the memory is output to the display panel.
In addition, output of incomplete image data to the display panel when tearing occurs may cause flickering during image display.

Abstract

If it is determined by a determination unit (34) that the distance between rp and wp is less than RDIST, then a period control unit (33) performs control such that the operation for reading out the next line is temporarily suspended until the distance between said rp and said wp becomes greater than or equal to RDIST.

Description

technical field [0001] The present invention relates to a memory control device that writes data transferred from a host processor into a frame memory, reads the data written into the frame memory, and transfers the data to a display panel such as an LCD (Liquid Crystal Display: liquid crystal display), and includes the memory A portable terminal of the control device, a memory control program, and a computer-readable recording medium on which the memory control program is recorded. Background technique [0002] Generally, when image data is transmitted from a main processor (hereinafter simply referred to as "host") to a display panel such as an LCD, the image data is a frame temporarily stored in an LCDC (LCD Controller: LCD Controller). The memory (hereinafter simply referred to as "memory") is output to the display panel. Accordingly, when there is no update of display data, there is no need to transfer image data from the host computer. [0003] However, in a seamless...
