Abstract

An image processing apparatus includes an image processing unit performing image processing in accordance with an image processing parameter; a first control unit storing the image processing parameter, which is to be used by the image processing unit, in association with address information, which is used to store the image processing parameter in the image processing unit, into a first storage unit on a basis of the image processing performed by the image processing unit; and a memory access unit writing the image processing parameter, which is read from the first storage unit, based on the address information in association with the image processing parameter on the basis of the image processing of the image processing unit.

Claims

1. An image processing apparatus comprising:

an image processing unit configured to perform image processing in accordance with an image processing parameter;

a first control unit configured to store the image processing parameter, which is to be used by the image processing unit, in association with address information, which is used to store the image processing parameter in the image processing unit, into a first storage unit on a basis of the image processing performed by the image processing unit; and

a memory access unit configured to write the image processing parameter, which is read from the first storage unit, based on the address information in association with the image processing parameter on the basis of the image processing of the image processing unit.

2. The image processing apparatus according to claim 1, further comprising:

a second control unit configured to, in response to a request from the first control unit, store the image processing parameter in association with the address information into a second storage unit.

3. The image processing apparatus according to claim 2,

wherein the second control unit includes a setting unit that is configured to set whether to use the second control unit and,

wherein, when the setting unit sets that the second control unit is to be used, the second control unit is configured to store the image processing parameter and the address information into the second storage unit.

4. The image processing apparatus according to claim 3,

Wherein, when the setting unit does not set that the second control unit is to be used, the second control unit is configured to write the image processing parameter based on the address information on the basis of the image processing of the image processing unit.

5. The image processing apparatus according to claim 2,

wherein the memory access unit is configured to write the image processing parameter, which is read from the first storage unit or the second storage unit, based on the address information on the basis of the image processing of the image processing unit.

6. The image processing apparatus according to claim 2,

wherein the memory access unit is configured to write the image processing parameter based on the address information, which is acquired from the first storage unit or the second storage unit, and based on address information which is acquired from base information on the basis of the image processing of the image processing unit.

7. The image processing apparatus according to claim 1,

wherein the memory access unit is configured to perform rewriting of the image processing parameter relative to the image processing unit on the image processing parameter which differs depending on whether the image processing parameter is for front-surface data or rear-surface data of manuscript data on which the image processing is to be performed.

9. An image forming apparatus comprising:

the image processing apparatus according to claim 1.

8. An integrated circuit comprising:

an image processing unit configured to perform image processing in accordance with an image processing parameter; and

a memory access unit configured to

read the image processing parameter from a first storage unit storing the image processing parameter, which is to be used by the image processing unit, in association with address information, which is used to store the image processing parameter in the image processing unit, on a basis of the image processing performed by the image processing unit, and

write the read image processing parameter based on the address information on the basis of the image processing of the image processing unit.
