An image processing apparatus obtains a black image captured in the light-shielded state, and applies a cyclic type filter to each line in a direction parallel to the streak in the black image, reducing random noise in the first direction. The image processing apparatus deletes, from a black image obtained by applying the cyclic type filter, lines in the second direction by the group delay of the cyclic type filter. Further, the image processing apparatus generates an image having a line count corresponding to the group delay by using a final line in the second direction in the image from which lines corresponding to the group delay have been deleted. The image processing apparatus adds the generated image to the image from which lines corresponding to the group delay have been deleted, and outputs the resultant image.

Image processing apparatus and control method thereof

An image capturing apparatus having a plurality of communication modes comprises an image capturing unit adapted to capture an object image and obtain image data, and a control unit adapted to control the image capturing apparatus, wherein the plurality of communication modes include a host mode in which the image capturing apparatus is able to communicate with a plurality of external devices and a client mode in which the image capturing apparatus is disable to simultaneously communicate with the plurality of external devices, and wherein the control unit is able to automatically switch the image capturing apparatus to the host mode after an image capturing instruction is applied to the image capturing unit.

Image capturing apparatus, control method therefor, and program

A black image captured in a light-shielded state is obtained, and the streak intensity is determined for each pixel of the black image from the absolute value of an AC component in a region containing the pixel. An extraction image which extracts streak-like fixed pattern noise in a captured image is generated using a black image obtained by applying, to the obtained black image, the first filter for reducing random noise in the first direction.

An image processing apparatus which is capable of preventing the display of an operation item, such as an icon, from hindering user's viewing an image which the user desires to view. A distance and position-detecting section and a system controller detect a distance between a screen and an operation element. The system controller displays at least one operation candidate item on the screen when the detected distance becomes not larger than a first threshold distance. Further, when the detected distance becomes not larger than the first predetermined threshold distance, the system controller changes a display form of the operation candidate item depending on the detected distance and displays the operation candidate item as an operable item.

A service providing unit adapted to provide a first service which transmits image data to the external apparatus under the control of the external apparatus on the network; a service retrieval unit adapted to retrieve the external apparatus, on the network, capable of providing a second service which processes the image data transmitted from the data management apparatus under the control of the data management apparatus; a service controlling unit adapted to control the external apparatus on the network such that the external apparatus provides the second service; and a switching unit adapted to switch between a first state that deactivates the service controlling unit and a second state that activates the service controlling unit based on a retrieval result by the service retrieving unit.

Data management apparatus, control method of data management apparatus, and computer-readable storage

A radio communication apparatus comprises a radio communication setting storage unit that stores a first radio communication setting for performing radio communication on a first radio network, and a second radio communication setting for performing radio communication on a second radio network which is different from said first radio network; a radio communication unit that performs radio communication using one of the first and second radio communication settings; and a radio communication setting switching unit that requests another radio communication apparatus in the first radio network to switch the first radio communication setting to the second radio communication setting in order to join the second radio network.

Radio communication apparatus and control method thereof

An electronic system comprising an image pickup unit, a computer, and communication terminals for connecting the unit and the computer, such as infrared communication ports, a card slot, and serial communication terminalswherein the necessary image data is allowed to be produced from the unitand transmitted to the computer through the communication terminals. The computer communicates with the image pick up unit by examining the port of each communication means in order to recognize whether a connected unit is the image pickup unit or a foreign unit and to determine and store the communication speed for each communication port. The image data and memory space information is then automatically transmitted to the computer and displayed on a device connected to said computer.

Electronic apparatus

An image file management apparatus capable of managing image data and attribute information associated with the image data includes an image file storage unit configured to store an image file including the image data and one or more pieces of attribute information associated with the image data, an attribute information recording unit configured to record at least one attribute information among the one or more pieces of attribute information included in the image file stored by the image file storage unit in association with an identifier of the image data, an attribute information disabling unit configured to disable the at least one attribute information recorded by the attribute information recording unit, and an attribute information restoring unit configured to restore and enable the at least one attribute information disabled by the attribute information disabling unit with respect to the image data.

An image sensing apparatus includes an image capture unit, a communication unit and a switch. The image capture unit captures a digital image using an image sensing device. The communication unit transmits a resume signal to an external computer, the resume signal being used by the external computer to release a suspended state. The switch enables the image sensing apparatus to capture a digital image using the image capture unit and enables the image sensing apparatus to transmit the resume signal to the external computer using the communication unit. Before the resume signal is transmitted to the external computer, the image sensing apparatus determines whether the external computer is in the suspended state. If it is determined that the external computer is in the suspended state, the image sensing apparatus enables the communication unit to transmit the resume signal to the external computer so as to release the suspended state.
