Abstract
An image processing apparatus includes at least one of one or more processors configured to implement instructions stored in a memory device and an integrated circuit that execute a first acquiring task of acquiring data of a first object from a first memory by designating an address in the first memory, a second acquiring task of acquiring data of a second object from a second memory by a first-in first-out (FIFO) scheme, and a bitmap image generation task of generating a bitmap image including at least the first object and the second object based on the data acquired in the first acquiring task and the data acquired in the second acquiring task.
Claims14
An apparatus comprising:
- a controller including a processor and a memory, the controller configured to:
- rasterize data of a first object to generate image data;
- compress the generated image data in a first memory;
- decompress the compressed image data and store the decompressed image data into a second memory, which is a first-in first-out (FIFO) memory;
- acquire data of a second object from a third memory, which is a random access memory (RAM) by designating an address in the third memory;
- acquire the decompressed image data from the first-in first-out (FIFO) memory;
- and
- generate combined image data representing at least the first object and the second object by rasterizing the acquired data of the second object based on the acquired decompressed image data.
A method for an apparatus, comprising:
- rasterizing data of a first object to generate image data;
- compressing the generated image data in a first memory;
- decompressing the compressed image data and storing the decompressed image data into a second memory, which is a first-in first-out (FIFO) memory;
- acquiring data of a second object from a third memory, which is a random access memory (RAM) by designating an address in the third memory;
- acquiring the decompressed image data from the first-in first-out (FIFO) memory;
- and
- generating combined image data representing at least the first object and the second object by rasterizing the acquired data of the second object and based on the acquired decompressed image data.
