  • Publication number: 20190019269
    Abstract: An image processing apparatus that performs a partial process with respect to each piece of divided image data obtained by dividing an input image expressed by input image data into partial regions using each object of an object group in which plural objects for executing image processing are connected to each other in a directed acyclic graph form, including: an assignment section that assigns a dependency relationship of processes to the partial processes between the connected the objects and assigns a priority to each partial process; a registration section that arranges executable partial processes on the basis of the dependency relationship in accordance with the assigned priorities and registers the result in an executable partial process list; and an execution section that executes the partial processes in a descending order of the priorities in the executable partial process list registered by the registration section.

  • Publication number: 20190019271
    Abstract: An image processing apparatus that executes image processing using an object group in which plural objects that perform image processing with respect to input image data stored in a storage region and output output image data are connected to each other is provided. The apparatus includes: a determination section that determines whether performing overwriting on the input image data using the output image data is possible according to each piece of processing content of the image processing; a controller that performs a setting for setting a storage region of the output image data of the image processing as a region including a storage region in which the input image data on which the overwriting is possible is stored, and performs a control for executing the image processing using the object group, with respect to the image processing for which it is determined that the overwriting is possible.

  • Publication number: 20180365793
    Abstract: An image processing device executes image processing by each object of an object group in which plural objects are connected to each other in a directed acyclic graph form. The image processing device includes: a division unit that divides image data as an image processing target into division image data having a first size; a subdivision unit that subdivides the division image data into subdivision image data having a second size smaller than the first size for each partial processing which is image processing to be performed on the division image data, the division image data corresponding to the partial processing which is determined as executable processing based on a pre-and-post dependency relationship; and a control unit that performs control for causing plural computation devices to execute subdivision partial processing which is image processing to be performed on the subdivision image data, in parallel.

  • Patent number: 8203733
    Abstract: An image processing apparatus according to an aspect of the invention includes a first storage unit, a second storage unit, a control unit, and a construction unit. A program of at least one module including a buffer module among modules of an image processing unit is stored in the first storage unit. An image processing program and a shared library can be additionally stored in the second storage unit. The image processing program is used to perform image processing and a program of a module generation unit is registered in the shared library. The control unit instructs at least one module in the image processing unit to perform image processing during construction of the image processing unit. The construction unit constructs the image processing unit.

  • Patent number: 7652671
    Abstract: An image processing device including a storage section, a parallel processing controller, a sequential processing controller, and a selection section which selectively operates the two control sections. The parallel processing controller connects one or more of the image processing modules such that first buffer modules are connected at least one of preceding and following each image processing module, to formulate a first image processing section, and controls such that individual image processing modules perform image processing in parallel with one another. The first buffer modules perform exclusive access control. The sequential processing controller connects one or more of the image processing modules such that second buffer modules are connected at least one of preceding and following each image processing module, to formulate a second image processing section, and controls such that the individual image processing modules perform image processing sequentially.

  • Patent number: 7415165
    Abstract: A red-eye detection device includes a red-eye candidate detection section, a red-eye pair specification section, and an isolated red-eye candidate check section. The red-eye candidate detection section detects a red-eye candidate that can be estimated to be a red-eye, by identifying a feature of the pupil that has a region displayed red from among features of an image. The red-eye pair specification section specifies the red-eye candidate as a pair of a right red-eye candidate equivalent to a right eye and a left red-eye candidate equivalent to a left eye, using information on a face region obtained from the image. The isolated red-eye candidate check section checks whether an isolated red-eye candidate, detected by the red-eye candidate detection section but not specified as the pair by the red-eye pair specification section, is a true red-eye.

  • Publication number: 20080129740
    Abstract: In an image processing apparatus, plural computational units execute computation relating to image processing. Plural image processing units cause the computational units to execute image processing on image information. A section number acquisition unit acquires a number of sections for sectioning the plural image processing units into groups. A sectioning unit sections the plural image processing units by causing the image processing units to belong to the respective groups based on the number of sections and the order of the image processing. A sequential storage processing unit receives requests for storage of the image information from image processing units belonging to the same group, and sequentially executes processing of the requests without performing exclusive access control.

  • Publication number: 20080005207
    Abstract: An image processing apparatus has an image processing section having modules and a storage resource management unit. The storage resource management unit determines whether or not a necessary capacity of a storage resource is equal to or less than a remaining amount of a memory when a module needs to be allocated with the storage resource, allocates the secured memory as the storage resource to the module when the capacity is equal to or less than the remaining amount or, when the capacity is larger than the remaining amount, secures a storage region of an external storage apparatus and allocates the storage region as the storage resource, or writes data written in a memory allocated to another module in the storage region and allocates the memory previously allocated to the other module as the storage resource to the module.
