Abstract
A method of processing digital images wherein: a plurality of images of reduced size are generated from a two-dimensional image, said reduced sizes being different from each other, said reduced size images are stored in memory, and a three-dimensional image is generated in real time from a frame provided with unit surfaces and from pixels chosen from said image and said reduced size images as a function of the orientation of a unit surface to which said pixel is to be assigned.
Claims12
A method of processing digital images wherein:
- a plurality of images of reduced size are generated from a two-dimensional image, said reduced sizes being different from each other,
- said images of reduced size are transmitted to a 3D accelerator encapsulated in accordance with a predetermined structure,
- said reduced size images are stored in memory by extracting said images from the encapsulation structure, and
- a three-dimensional image is generated in real time from a frame provided with unit surfaces and from pixels chosen from said image and said reduced size images as a function of the orientation of a unit surface to which said pixel is to be assigned.
A method according to any preceding claim, wherein storage in memory is effected in accordance with a particular writing order.
A method according to any preceding claim, wherein reading in memory is effected in a particular order.
A method according to any preceding claim, wherein said reduced size images are formatted inside the format of said image so that all of said reduced size images occupy less than or the same space as said image.
A method according to any preceding claim, wherein the three-dimensional image is stored in memory.
A method according to any preceding claim, wherein the three-dimensional image is sent to a display system.
A system for processing digital images including a digital terminal (15), a central unit (21), a memory system and a display unit (23), characterized in that the digital terminal includes a bit block processor module (24) adapted to reduce the size of a two-dimensional image and an auxiliary memory (22) associated with the digital terminal for generating a three-dimensional image from a frame provided with unit surfaces and from pixels chosen from said two-dimensional image and the reduced size images from the bit block processing module as a function of the orientation of a unit surface to which said pixel is be assigned, in which system the memory system is adapted to store a plurality of reduced size images (4 to 7) derived from a two-dimensional image (1), said reduced sizes are different from each other, and said three-dimensional image is sent to the display unit
