An image forming device is disclosed that is able to prevent halt of operations due to full memory occupation, and prevent the full occupation of the memory. The image forming device includes a reading unit; an image data storage unit; a vacancy waiting unit that, when allocating a storage area for storing image data in the image data storage unit, waits until the storage size of a vacancy in the image data storage unit becomes greater than a predetermined value when allocation of the storage area fails; a failure processing unit that, when allocating the storage area for storing the image data in the image data storage unit, performs failure processing when allocation of the storage area fails; and a control unit that controls one of the vacancy waiting unit and the failure processing unit according to image forming conditions in the image forming device.

Image forming device

A disclosed image formation apparatus includes: an operation unit allowing input of reading conditions of image data; an input unit reading the image data in accordance with the reading conditions input via the operation unit; a first storage unit storing the image data read by the input unit; a second storage unit storing correspondence relation between the reading conditions and predicted data amount of the image data to be stored in the first storage unit; a data amount prediction unit predicting data amount of the image data to be read based on the reading conditions and the correspondence relation stored in the second storage unit; and a judgment unit judging whether to perform reading of the image data based on the predicted data amount and an available capacity of the first storage unit.

Method, apparatus, and computer readable storage medium for predicting a data amount for image data prior to reading the image data

An image forming apparatus is disclosed. The image forming apparatus comprises an input unit through which a condition for reading image data of a document is input, a reading unit to read the image data under the reading condition, a first storage unit to store the image data read by the reading unit, a second storage unit to store information indicative of a relationship between the reading condition and an estimated volume of the image data to be stored in the first storage unit, a data volume estimating unit that estimates a volume of the image data to be read based on the reading condition and the information stored in the second storage unit, and a determining unit to determine whether to read the image data based on the estimated data volume and a volume of the image data that have already been stored in the first storage unit.

Image forming apparatus and information processing method

An image processing apparatus, includes an image reading part configured to read an image of a document; and an image storage part configured to store image data read by the image reading part; wherein the image reading part includes a part configured to read a range of a part of the image of the document; the image processing apparatus further includes: a first calculating part configured to calculate image data of a one surface of the document based on a size of the image data of the range read by the image reading part; and a second calculating part configured to calculate the number of pages of image data of the document which can be stored by the image storage part based on the result of calculation by the first calculating part.

Image processing apparatus

A disclosed image forming apparatus includes: an image data input unit inputting image data; an image data storage unit storing the image data; a storage method change unit changing a storage method of the image data; an image data output unit outputting the image data; an available capacity detection unit detecting available capacity of the image data storage unit; an available capacity judgment unit judging whether the available capacity is not more than a predetermined value; and a storage method selection unit prompting selection of a storage method performed by the image data storage unit. When the available capacity is judged to be not more than the predetermined value, the storage method selection unit prompts the selection of a storage method, the storage method change unit changes the storage method of the image data, and the image data output unit outputs image data.

Apparatus and method for changing storage methods of image data based on available storage capacity

In a disclosed image forming apparatus, an original is scanned and image data of the original are obtained. The data size of the image data corresponding to one page of the original is measured. The image data obtained are stored in or deleted from a memory. A storable number of pages of the original that can be stored in the memory is calculated based on the data size measured and available space in the memory. In response to the storable number of pages calculated being less than a total number of pages of the original, the image data of the original is successively stored in and deleted from the memory.

Image forming apparatus including a storable page number calculating unit

An image forming apparatus includes a print-request information inputting unit, an image reading unit, a plurality of image forming units, a plurality of sheet feeding units, a memory unit and a control unit wherein the control unit reading out, when print-request information is inputted, ID information and device information from a memory unit and selects, based on the plural ID information, the device information and the print-request information, an optimum image forming unit that satisfies the print-request information. The control unit further causes the selected image forming unit to execute print processing.

Image forming apparatus including a print-request information inputting unit and image reading unit, and image forming method

An image forming apparatus includes two or more detachable components that are identical to each other and configured to perform at least part of a sequence of processes associated with forming of an image, a connection detection unit configured to detect attaching of the components, and a first control unit configured to control the sequence of processes, wherein a software-based controller for controlling one of the components is generated in response to detection by the connection detection unit of the attaching of the one of the components.
