The method may include obtaining a current image generated based on an exposure parameter, wherein the current image includes a plurality of pixels; determining a plurality of target pixels or target pixel groups from at least portion of the plurality of pixels; determining a statistic representation based on target pixels or target pixel groups; determining a characteristic feature based on the statistic representation; and, updating the exposure parameter, based on the characteristic feature, to generate an updated image.

A printing apparatus includes a receiving unit which receives print data, an operating unit which receives a print instruction from a user, a display unit which displays a password entry screen for receiving a password entry from a user, and a printing unit which receives a print instruction from a user through the operating unit and prints print data without accepting a password through a password entry screen if a password added to the print data is matched with a fixed password and print data to be printed if a print instruction from a user is received through the operating unit, if the password added to the print data is matched with the fixed password, and if the password received through a password entry screen is matched with the password added to the print data.

An image processing apparatus, including a display, a memory, and a controller, to provide a plurality of functions is provided. The controller controls the display to display one of a first screen, through which one of the plurality of functions is selectable; a second screen, through which one of a plurality of options for the selected function is selectable; and a third screen, through which selection of the one of the plurality of options is indicated. When the controller reads shortcut information that indicates a first option for a selected one of the functions, and when the first option is permitted to the user, the third screen is displayed. When the first option is not permitted to the user, and if there is a second option permitted to the user, the second screen is displayed.

According to an aspect of the disclosure, an information processing apparatus comprising a communication circuit and a control circuit is provided. The control circuit transmits reduced image data of captured image data, to a first external apparatus through the communication circuit; receives, from the first external apparatus, a result of evaluation processing applied to the reduced image data; on the basis of the result of the evaluation processing, determines whether to apply image processing to the captured image data corresponding to the reduced image data, by a second external apparatus; transmits the captured image data that is determined to be applied the image processing, to the second external apparatus through the communication circuit; and receives, from the second external apparatus, a result of the image processing applied to the captured image data.

A server apparatus provides a social networking service (SNS). The server apparatus stores a specific relation between a terminal apparatus and a printer that are allowed for communication using the SNS. The server apparatus stores relations between one or more icons and commands each corresponding to a respective one of the icons and including an image forming condition and an image forming instruction. Upon receiving a selected icon having been selected on the terminal apparatus, information indicating a selected printer having been selected on the terminal apparatus out of printers in specific relations with the terminal apparatus, and a piece of image data from the terminal apparatus, the server apparatus transmits a command corresponding to the selected icon and the piece of image data to the selected printer.

According to an aspect of the disclosure, an information processing apparatus comprising a communication circuit and a control circuit is provided. The control circuit transmits reduced image data of captured image data, to a first external apparatus through the communication circuit; receives, from the first external apparatus, a result of evaluation processing applied to the reduced image data; on the basis of the result of the evaluation processing, determines whether to apply image processing to the captured image data corresponding to the reduced image data, by a second external apparatus; transmits the captured image data that is determined to be applied the image processing, to the second external apparatus through the communication circuit; and receives, from the second external apparatus, a result of the image processing applied to the captured image data.

An image forming apparatus includes a communication unit configured to communicate with an external controller, a reception unit configured to receive, in a case where a predetermined error related to the communication occurs, log information on the predetermined error from the external controller, and a storage control unit configured to store, in a storage unit of the image forming apparatus, the log information received from the external controller and log information indicating an operation of the image forming apparatus corresponding to a timing at which the predetermined error has occurred.

An image forming system includes a mobile terminal apparatus and an image forming apparatus. The mobile terminal apparatus displays a captured image of an operation panel of the image forming apparatus, extracts from the captured image, in response to a user operation on the captured image, an operation partial image including an operation part designated by the user operation, and transmits operation partial image data indicating the operation partial image to the image forming apparatus. The image forming apparatus identifies the operation part corresponding to the operation partial image data received from the mobile terminal apparatus, and executes an action corresponding to the identified operation part.

A print management unit attaches an identifier to print data that goes through a custom processing unit functioning by execution of a custom class driver, and delivers the print data with the identifier attached, to a standard print control unit. The custom processing unit deletes the identifier from the print data delivered from the standard print control unit and customizes processing of causing a printer to execute printing, based on the print data. The print management unit detects a read state of the custom class driver by execution of an OS. When the read state indicates a failure in reading the custom class driver, the print management unit delivers the print data without the identifier attached, to the standard print control unit, and thus causes the printer to execute the printing that is limited via a standard communication control unit or to stop the printing.

Embodiments of the present application provide a data transmission method, a camera and an electronic device. The method includes: acquiring to-be-sent target data; and sending the target data, as data carried in an effective image area of a first image frame, by using a data sending manner for the effective image area, through a same transmission channel as used in transmitting image data; wherein, the target data is different from the image data and coaxial data, the coaxial data is notification information for an interaction between a data receiving end and a data sending end, and the first image frame has a different type from a second image frame carrying the image data without carrying the target data. Applying the solutions provided by the embodiments of the present application, the transmission of the target data can be realized without additional wiring, thereby reducing the device cost.
