A method and apparatus for dithering may provide filtering M bit data and performing a temporal / spatial compensation based on LSB of the filtered M bit data. The dithering may be performed on a selected frame. M-2 bits of the M bit data may be specified as a reference gray scale value resulting from the filtered M bit data. Temporal compensation may provide adding a weight of ‘0’ or ‘1’ to the reference gray scale value, for example M-2 bit data. Spatial compensation may include horizontal or vertical mirroring, and may be performed to represent whole gray scales without saturation.

A robot device (1) has a central processing process (CPU) having a plurality of objects and adapted for carrying out control processing on the basis inter-object communication carried out between the objects, the central processing process controlling accesses by the plurality of objects to a shared memory shared by the plurality of objects and thus carrying out inter-object communication. Specifically, the central processing process generates pointers P 11 , P 12 , P 13 , P 21 , P 22 in accordance with accesses by the objects to predetermined areas M 1 , M 2 on a shared memory M, then measures the pointers by the corresponding number-of-reference measuring objects RO 1 , RO 2 , and controls the accesses in accordance with the number of pointers measured, thereby carrying out inter-object communication. This enables easy realization of smooth inter-process communication.

The invention discloses a system for access control of a unidirectional light bus network based on priority level dynamic regulation. The unidirectional light bus comprises a convening node, M-2 intermediate nodes and a termination node, wherein M is no less than 3 and is a natural number, and data stream of each node on the unidirectional light bus is in a single service type. The system for theaccess control of the unidirectional light bus network based on the priority level dynamic regulation comprises a node criticality parameter computing module, a movable node duty ratio computing module, a tag value computing module and a priority level judging module; and according to the priority level judging module, when a request reaches a node on the light bus, data is sequentially transmitted according to the priority level. The invention improves liveness of the light bus, meets real-time requirements, ensures that all the nodes (users) on same light bus meets information transmission delay requirements respectively, and simultaneously achieves the purpose of improving the use ratio of the light bus.
