Abstract: An image forming apparatus is arranged such that one reference test pattern image expressed in a tone expression is formed on the predetermined image bearing member, the tone expression being different from a tone expression of an image formed in the print modes that carry out a normal print process, and density of the formed reference test pattern image is detected, and subsequently sets of density correction data for the print modes are created based upon the detected density.

Abstract: One embodiment of an image correction method is an image correction method for correcting image forming condition(s). The image correction method includes forming, on photoreceptor(s), correction test pattern(s) having continuously varying toner gradation; wherein a single correction test pattern in which density is varied in sequence from high to low in paper transport direction(s) is formed as a result of controlling exposing unit laser power(s) while photoreceptor charging potential(s) is/are held constant, or while develop bias(es) is/are held constant, or while photoreceptor charging potential(s) is/are held constant and develop bias(es) is/are held constant. In such case, total length(s) in paper transport direction(s) of such correction test pattern(s) is/are less than or equal to circumference(s) of photoreceptor(s).

Abstract: In operation processing devices based on Java (a registered trademark), each time a functional program is executed, in response to a command to access that function, a work area for the program which is accessed is set up dynamically within the thread work area for the thread then being executed. By applying this processing in the case of an external interrupt as well, this invention eliminates the need to maintain a separate memory area for interrupt program processing. It simplifies the processing involved in sidetracking and restoring data and switching the program to be executed. The work area for a program being run is a dynamically created memory area according to this invention. When an interrupt is generated, the register data indicating the status and register state of the program being run at that time are sidetracked in the work area for that program.

Abstract: A device is provided with a control device that activates a stack machine and that also controls thread switching. This will reduce both the hardware requirements and the number of development processes needed to produce a switching control mechanism. It will also allow the threads to be switched very rapidly. The circuit to control thread switching: 1) discriminates a next thread to be switched to; 2) sidetracks the register data indicating the current state of execution of the program stored in the control register group in the stack machine in response to the request to switch threads and stores them in a sidetracking area set up for the current thread; and 3) reads the register data out of the sidetracking area for the thread that is switched to, which has been recognized by the discrimination unit, after the current data have been sidetracked by the sidetracking processor.

Abstract: The objective of this invention is to eliminate wasteful use of the memory resource, reduce complexity of program switching or thread interrupt program processing, and speed up program processing. In operation processing devices based on Java (a registered trademark), each time a functional program is executed a memory work area is dynamically created. This invention eliminates the need to maintain a separate memory thread work area for interrupt program processing. It simplifies the processing involved in sidetracking and restoring data required to switch between threads or programs to be executed. The work area for a program being run is a dynamically created memory area according to this invention. When an interrupt is generated, the register data indicating the status and register state of the program being run at that time is sidetracked into the work area for that program.
