Description

  The present invention relates to an image information format generation procedure for data transmission / reception between an image processing apparatus having an image reading means and a portable device.

  Image information read by digital cameras and scanners has rapidly increased in resolution and data has been enlarged due to advances in reading equipment.

  Conventional general image handling formats have been created considering only the correspondence to the data size.

  The purpose of reducing the size is also to perform run-length compression such as facsimile and JPEG compression in image storage.

  However, in these formats for the purpose of size compression, partial use of images and searchability of related images are equal.

  Even in the case of partial use of an image, it is necessary to restore the original image once and then cut out a necessary area, which is a low operational efficiency.

  These image processing operations with low operational efficiency are disadvantageous in portable devices.

  This is because the amount of energy that can be used in a portable device is very limited in terms of medium weight and supply amount itself.

  With the advance of semiconductor devices, the computing power itself has advanced, and it has become possible to process image data conversion sufficiently even if electric energy is sufficiently supplied.

  However, the size of the power source that can be carried is limited, and the operation time of the portable device is limited by the data conversion processing with low energy efficiency, and the merit of portability is offset.

  In order to operate image information that is more convenient and efficient, it is necessary to avoid inefficient arithmetic processing as much as possible.

  Effectively structuring image information with a large amount of data is effective for efficient arithmetic processing.

  In conventional structured image data creation, multiple pieces of image information are associated and additional information is attached. However, efficient processing is not possible to some extent by associating each piece of information as it is. .

  Japanese Patent Application Laid-Open No. 2004-228561 refers to image reduction of a still image.

  In Patent Document 2, image division processing is performed, and divided image groups are handled as hierarchical data.

  None of these are image conversion processes that take into account the display capability of the communication destination device.

Therefore, in the present invention, in a printing apparatus having a composite function including an image reading scanner operation, a copying function, etc. in addition to a printing function,
Implement the following functions.

An image processing apparatus having image reading means (400) / image generation means / image income means,
An image size based on the display capability information of the portable device from the original image data obtained by the income means of the image based on the display capability information of the portable device having communication means (401) with the portable device Multiple secondary images of
Composite image information including a secondary image group and an original image group is generated, and the generated composite image information is sent to the portable device.

  By implementing the above processing at the time of communication with a portable device, a light portable device can be operated.

  According to the present invention, it is possible to easily handle complex image information without imposing a large calculation load on the portable information device and without wasting power.

Example 1
FIG. 1 is a configuration example of a general printing mechanism having a composite function.

  Reference numeral 400 denotes image reading means.

  401 is a communication means.

  Communicates with external devices including communication with portable devices.

  Reference numeral 402 denotes calculation means.

  An image conversion process is performed, or an image is generated based on a drawing control command.

  Reference numeral 403 denotes storage means. The generated composite image information is stored, or the original image from which the composite image information is based is stored.

  Various setting information of the image processing apparatus itself, a database of portable devices, and the like are also stored.

  Based on the image information read in 400 or the image information generated on the page memory 100 on the page 403 based on the drawing control command received by the communication means 401, composite image information is generated.

  The original image information of the composite image information may also be composite image information that has already been created or received from an external device.

  Therefore, 401 may directly receive original image information or composite image information.

  Reference numeral 404 denotes an image output mechanism.

  Print image information is output to the print mechanism 411.

  Reference numeral 405 denotes temporary storage means.

  It is used as a temporary area for generating composite information of image data on the temporary storage means.

  Reference numeral 406 denotes an input / output.

  Exchanges information with the printing mechanism and user interface.

  Reference numeral 411 denotes a printing mechanism.

  Print output is performed in normal copying machine operation and printer operation.

  Although it is not a direct output in the present invention, a user's convenience may be measured by printing out guidance or the like to supplement the GUI.

  Reference numeral 412 denotes a user interface.

  It comprises display means and operation means, and displays images and gives instructions to the image processing apparatus.

  Connection authentication with a portable device, image selection, mode selection, and the like are performed via 412.

  FIG. 2 is a flowchart showing a processing procedure characteristic of the present invention.

  In this procedure, it is assumed that all necessary original images have already been read and generated.

  Reference numeral 1000 denotes an operation start step.

  A procedure for generating composite information of an image on a portable device is started by the user's selection.

  Reference numeral 1001 denotes a connection waiting step with the portable device.

  Reference numeral 1002 denotes a connection establishment step.

  Communication is negotiated and data can be freely sent and received.

  Reference numeral 1003 denotes an equipment information income step.

  Requests device information from the image processing apparatus to the portable device.

  The required device information is display panel size information and number.

  Some portable devices use a window that is slightly smaller than the pixel size of the physical panel in the GUI.

  In such a case, window size information is requested.

  If there are multiple display panels and they can be used for the same purpose at the same time, it is possible to display a wider image by treating the device as a single continuous panel with multiple displays.

  In order to generate composite image information corresponding to such a case, a number and individual display capabilities are required.

  Some portable devices do not have a function of presenting their own display capability.

  For such a case, a database of portable devices is prepared on 403, and display capability information is stored therein.

  Reference numeral 1004 denotes a data income step.

  Obtain display capability information from a portable device, or search for display capability information from a database, and prepare data conversion work based on it.

  Reference numeral 1006 denotes an image selection step.

  Image processing is entered with the image and operation selected.

  Reference numeral 1007 denotes a data conversion processing step.

  An actual image conversion process is performed.

  A reduced image having a size matching the display capability information of the mobile device is generated from the original image, or the original image information is subdivided into the display size as it is based on the display capability information.

  For example, it is assumed that the information that the original image is 2000 × 2000 and the display capability information of the mobile device with which communication is established is 300 × 500 is obtained.

  Various images are generated based on the image size information.

  A 300 × 300 image is generated by reducing the original image to 15% size so that the entire image can be viewed, or an image group is generated by dividing the original image into 7 × 4 = 28 300 × 500 images.

  Alternatively, an image with an image size of 300 × 500 is created with an intermediate reduction ratio.

  The created image group is collected into one file and additional information is added.

  FIG. 3 shows a schematic diagram of the image composite information generated.

  Based on the display capability information, a reduced image or a divided image is created and combined into one.

  In the grouped image group, it is necessary to add index information so that individual image information can be accessed.

  Compound image information is generated by adding other non-image information.
