Abstract: A moving picture display apparatus comprises a main body and an external memory detachably mounted on the main body. The main body of the moving picture display apparatus is provided with a video data memory for storing therein graphic data of characters which constitute objects. A program data memory of the external memory has object data of an object to be displayed on a raster-scan type monitor, i.e., color pallet data, object name data, vertical position data, horizontal position data, object size selection data and size designation data and etc., all of which have previously been stored therein. Object data of an object to be displayed during the next vertical period is read from the program data memory so as to be stored in an object attribute memory.

Abstract: A background picture display apparatus includes a microprocessor and an external storage unit, and dot data, character designating data and mode data are programmed in advance in a ROM in the external storage unit. Character designating data constituting background screens designated by the mode data and dot data of the respective characters used in the background screens are loaded in a RAM, that is, a screen RAM and a character RAM by a microprocessor. The character designating data is read from the screen RAM, and the dot data of the character is read from the character RAM. The dot data is converted into serial data by a parallel-serial conversion circuit, and a dot data combination circuit generates a color code for each background screen by combining the dot data and applies the same to a color generation circuit.

Abstract: A video processing apparatus includes a VRAM in which image data of an original background picture is stored. An address of the VRAM in a case where the original background picture is rotated and enlarged or reduced is calculated by a background picture address control circuit on the basis of constants set by a CPU. Color data of the background picture at the time of rotation processing and enlargement or reduction processing is read from the address of the VRAM, and a video signal is generated by the color data.
