Abstract
An image processing apparatus is provided which can execute a rotation process of an image when there is insufficient storage capacity. In a multi-function device to read images on two sides of a document by reversing a transfer direction of the document in an automatic document feeder, an estimated available capacity can be obtained based on a previously set condition, such as the resolution or gradation of an image scanner. Based on the estimated available capacity, it can be judged whether the rotation process can be performed. When the rotation process can not be performed, a process to reduce a set value of the condition is executed. When the set value of the condition is reduced, an attempt can be made to execute the process under the reduced set value.
Claims21
An apparatus for processing images previously-formed on first and second sides of a document based on a first condition, comprising:
- an image scanner having a scanning position, the image scanner scanning images on a document at the scanning position as the document and the scanning position move relative to each other;
- a first storage section configured to store image data scanned by the image scanner;
- memory configured store computer-executable instructions;
- and
- a processing unit configured to execute the computer-executable instructions that, when executed cause the image processing apparatus to provide:
- an estimate section configured to estimate an amount of data to be scanned based on estimate information;
- a judgment section configured to judge whether a rotation process to rotate one of a first side image and a second side image scanned by the image scanner can be performed based on the estimated data amount and an available storage capacity of the first storage section;
- and
- a change section configured to change a first condition by reducing the amount of data to be scanned by the image scanner from the first side or the second side of the document when the judgment section judges that the rotation process can not be performed,
- wherein when the judgment section judges that the rotation process can not be performed, the change section automatically reduces a set value of the scanning condition based on a previously determined reduction ratio.
An apparatus for processing images previously-formed on first and second sides of a document based on a first condition, comprising:
- an image scanner having a scanning position, the image scanner scanning images on a document at the scanning position as the document and the scanning position move relative to each other;
- a first storage section configured to store image data scanned by the image scanner;
- memory configured store computer-executable instructions;
- and
- a processing unit configured to execute the computer-executable instructions that, when executed cause the image processing apparatus to provide:
- an estimate section configured to estimate an amount of data to be scanned based on estimate information;
- a judgment section configured to judge whether a rotation process to rotate one of a first side image and a second side image scanned by the image scanner can be performed based on the estimated data amount and an available storage capacity of the first storage section;
- and
- a change section configured to change a first condition by reducing the amount of data to be scanned by the image scanner from the first side or the second side of the document when the judgment section judges that the rotation process can not be performed,
- wherein the image scanner executes scanning under a second condition that the amount of data to be scanned is small relative to the first condition.
An apparatus for processing images previously-formed on first and second sides of a document based on a first condition, comprising:
- an image scanner having a scanning position, the image scanner scanning images on a document at the scanning position as the document and the scanning position move relative to each other;
- a first storage section configured to store image data scanned by the image scanner;
- memory configured store computer-executable instructions;
- and
- a processing unit configured to execute the computer-executable instructions that, when executed cause the image processing apparatus to provide:
- an estimate section configured to estimate an amount of data to be scanned based on estimate information;
- a judgment section configured to judge whether a rotation process to rotate one of a first side image and a second side image scanned by the image scanner can be performed based on the estimated data amount and an available storage capacity of the first storage section;
- a change section configured to change a first condition by reducing the amount of data to be scanned by the image scanner from the first side or the second side of the document when the judgment section judges that the rotation process can not be performed, and
- a second storage section configured to store a correspondence relation between the estimate information and a set data amount previously determined according to the estimate information,
- wherein the estimate section extracts the set data amount corresponding to the estimate information, as the estimated data amount, from the correspondence relation stored in the second storage section.
An apparatus for processing images previously-formed on first and second sides of a document based on a first condition, comprising:
- an image scanner having a scanning position, the image scanner scanning images on a document at the scanning position as the document and the scanning position move relative to each other;
- a first storage section configured to store image data scanned by the image scanner;
- an estimate section configured to estimate an amount of data to be scanned based on estimate information;
- a judgment section configured to judge whether a rotation process to rotate one of a first side image and a second side image scanned by the image scanner can be performed based on the estimated data amount and an available storage capacity of the first storage section;
- and
- a change section configured to change a first condition by reducing the amount of data to be scanned by the image scanner from the first side or the second side of the document when the judgment section judges that the rotation process can not be performed,
- wherein when the judgment section judges that the rotation process can not be performed, the change section automatically reduces a set value of the scanning condition based on a previously determined reduction ratio.
