Abstract

An image processing apparatus includes: a writing controlling unit that writes image information of an input image to a memory; a detecting unit that detects one of a plurality of blocks into which the input image is divided, the one being a block for which writing of corresponding image information to the memory is completed; and a correcting unit that performs a process of correcting a distortion occurring in the input image, for each block in order in which the blocks are detected by the detecting unit.

Claims

1. An image processing apparatus comprising:

a writing controlling unit that writes image information of an input image to a memory;

a detecting unit that detects one of a plurality of blocks into which the input image is divided, the one being a block for which writing of corresponding image information to the memory is completed; and

a correcting unit that performs a process of correcting a distortion occurring in the input image, for each block in order in which the blocks are detected by the detecting unit.

2. The image processing apparatus according to claim 1, further comprising a metadata memory storing therein metadata indicating order of the blocks in which writing to the memory is completed depending on the distortion occurring in the input image, wherein

the detecting unit detects if the writing of the image information to the memory is completed in the order of the blocks indicated by the metadata.

3. The image processing apparatus according to claim 1, wherein the writing controlling unit writes the image information of the input image to the memory in units of a horizontal line.

4. A communication system comprising:

a plurality of terminal devices, each of the terminal devices including;

a writing controlling unit that writes image information of an input image to a memory;

a detecting unit that detects one of a plurality of blocks into which the input image is divided, the one being a block for which writing of corresponding image information to the memory is completed;

a correcting unit that performs a process of correcting a distortion occurring in the input image, for each block in order in which the blocks are detected by the detecting unit; and

a transmitting unit that transmits the image information subjected to the process of correcting over a certain network, wherein

the terminal devices exchange the image information over the network.

5. The communication system according to claim 4, wherein each of the terminal devices further includes a metadata memory storing therein metadata indicating order of the blocks in which writing to the memory is completed depending on the distortion occurring in the input image, and

the detecting unit detects whether the writing of the image information to the memory is completed in the order of the blocks indicated by the metadata.

6. The communication system according to claim 4, wherein the writing controlling unit writes the image information of the input image to the memory in units of a horizontal line.

7. A computer program product comprising a non-transitory computer-readable medium containing an information processing program, the program causing a computer to function as:

a writing controlling unit that writes image information of an input image to a memory;

a detecting unit that detects one of a plurality of blocks into which the input image is divided, the one being a block for which writing of corresponding image information to the memory is completed; and

a correcting unit that performs a process of correcting a distortion occurring in the input image, for each block in order in which the blocks are detected by the detecting unit.

8. The computer program product according to claim 7, wherein the detecting unit detects whether the writing of the image information to the memory is completed in order of the blocks indicated by metadata indicating order of the blocks in which writing to the memory is completed depending on the distortion occurring in the input image.

9. The computer program product according to claim 7, wherein the writing controlling unit writes the image information of the input image to the memory in units of a horizontal line.
