An on-screen display unit solves a problem of a conventional on-screen display unit. The conventional unit cannot implement a moving display of an image with a small amount hardware. The novel on-screen display unit includes a first memory for storing the image code of each of images to be displayed. A second memory stores font data of the images. A latch circuit stores information indicating one of a moving display ON mode and a moving display OFF mode. A line memory stores at least one horizontal line image. An image data generating unit generates image data to be stored in the line memory. A selector selects output data from the second memory when the latch circuit stores information indicating the moving display OFF mode and selects output data from the line memory when the latch circuit stores information indicating the moving display ON mode.
An on-screen display unit for displaying static and moving images on a display screen, the on-screen display unit comprising:
An image display method for an on-screen display unit including a first memory for pre-storing fonts of static images to be displayed on a display screen, a line memory for storing at least one horizontal line of a moving image to be displayed on the display screen, a selector for selecting one of output data from said first memory and output data from said line memory, and a central processing unit for control of the on-screen display unit, the image display method comprising:
