An image forming apparatus includes an image bearing member, a developing unit to develop an electrostatic latent image formed on the image bearing member with toner, and a detachable toner container in which toner for supplying to the developing unit is contained. A measuring unit measures information relating to an amount of toner in the developing unit, and a determination unit determines an amount of toner in the developing unit based on the measured information. In a case where the determination unit determines that the toner container is empty, a supply operation for supplying toner from the toner container to the developing unit is performed and the measuring unit measures the information relating to an amount of toner in the toner container after the supply operation is performed, and in a case where the information relating to an amount of toner in the toner container measured after the supply operation is performed is within a measurement error range, the determination unit determines that the toner container is empty.

An information processing apparatus that generates a file in a prescribed image file format is provided. The information processing apparatus accepts a designation of a storage condition to be satisfied by image data to be stored in the prescribed image file format, obtains image data, and generates the file such that one or more image data included in the obtained image data and satisfying the storage condition are stored in one of the prescribed image file format and such that image data included in the obtained image data and not satisfying the storage condition is not stored in the one of the prescribed image file format.

An image processing apparatus includes a memory holding image data generated by an image reader; a memory controller for accessing the memory; first and second image processors for executing image processing on the image data one line at a time, the second image processor being added when implementing functional expansion; a connector for connecting the first and second image processors by a transfer path of the image data when implementing the functional expansion; first and second generators for respectively generating first and second allowance signals for allowing reading of a next line of the image data from the memory, according to the image processing times taken by the first and second image processors; and an allower configured to output, to the memory controller, a third allowance signal for allowing reading of the next line of the image data from the memory, based on the first and second allowance signals.

An image processing apparatus that transfers recorded image data includes a control unit configured to perform control in such a manner that in a case where transfer of image data is instructed during recording of the image data, previously recorded image data is set as a transfer target when a predetermined period of time has not elapsed after recording of the previously recorded image data is stopped, and image data currently being recorded is set as the transfer target when the predetermined period of time has elapsed.

An image processing apparatus, comprises a recording control unit configured to perform control to, when extracting a frame from a RAW file in which RAW data of a plurality of frames is recorded and recording the extracted frame as a RAW still image file, record RAW data of the extracted frame and information indicating that predetermined image processing has been applied to the RAW data into the RAW still image file.

An example device includes at least one camera and a touchscreen user interface including thumbnail images for a plurality of stored pictures and a first button for a communication operation for sending a picture corresponding to a selected thumbnail image to another device.

An image processing method includes, when an edit triggering event for a target image is detected, acquiring description information associated with the target image. The description information includes interference information that affects image quality occurred in a shooting process of the target image. The method further includes editing image clips in the target image which are associated with respective interference information of the description information to obtain a processed target image.

An electronic device and a controlling method of the electronic device are provided. The controlling method of an electronic device according to the disclosure includes the steps of, based on a first user input for or related to acquiring a live view image through a camera including a plurality of lenses different from one another being received, acquiring a plurality of image frames for each of the plurality of lenses and storing the image frames in a first memory, inputting the plurality of image frames for each lens stored in the first memory into a neural network model, by a predetermined time interval, and acquiring score information including composition preference information of each of the input image frames, selecting at least one lens among the plurality of lenses based on the score information, storing image frames acquired through the selected at least one lens in a second memory during the predetermined time interval, and based on a second user input for initiating recording of the live view image being received, storing an image related to the image frames stored in the second memory in a third memory until a time point when a third user input for ending the recording is received.

A video recording device to be worn by a user, the video recording device including a main body, a camera disposed on at least a portion of main body to record at least one of at least one picture and at least one video thereon, a control unit disposed within at least a portion of the main body to direct the camera to record the at least one video for a predetermined duration in response to a real time mode being activated and save the at least one video for the predetermined duration in response to receiving a save command, and an ear connector disposed on at least a portion of the main body to removably connect the main body to an ear of the user.

An image processing apparatus includes: a display; a memory that stores multiple key frames of a video guide on how to recover from an operating error; an error sensor that detects the operating error; and a display processor that allows the display to display at least one of the multiple key frames as a still frame for a digest along with an operation button for video playback, when the error sensor detects the operating error, the multiple key frames being stored on the memory, and that further allows the display to play back the video guide by serially displaying the multiple key frames, when the operation button is pressed.
