In a composite machine provided with a copy mode and a print mode, an operation history of each operation mode is accurately timed and log information concerning an electric power of the composite machine for processing various jobs such as the copy mode and the print mode is prepared based on a timed value.

Image processing apparatus, information processing apparatus, and information output method

Conventionally, it is impossible to securely and efficiently implement the judgment of specific images. In order to solve this task, an image processing apparatus according to the present invention is characterized in including an input unit (in these embodiments, this corresponds to, for example, the interface unit in FIG.) for inputting color image data, an judging unit (this corresponds to, or example, the forgery judging unit in FIG.) for judging whether the judgment of whether a color image composed of the color image data is a specific image has been already performed, and an image judging unit (this corresponds to, for example, the forgery judging unit in FIG.) for judging whether the color image include the specific image if the judgment has not been performed yet.

Image processing system for preventing forgery

Control over processing of image data in a system comprising a plurality of scanning devices and a plurality of printing devices, each of which may or may not include a forgery-preventing function. An image processing apparatus receives information for each of the plurality of scanning devices and printing devices indicating whether or not they include a forgery-preventing function. When image data is received by the image processing apparatus, the image processing apparatus controls the processing of which printing apparatus the image data can be sent to for printing. If the image data is received from a scanning apparatus that includes a forgery-preventing function, the image data can be sent to any printing device, regardless of whether or not it includes a forgery-preventing function. If the image data is received from a scanning apparatus that does not include a forgery-preventing function, the image can be sent only to a printing device that does include a forgery-preventing function. Further, a display of available printers to which an operator can select to send the image data may be provided for, with the displayed available printers being controlled based on whether the image data is received from a scanning device that includes a forgery-preventing function or not.

Image processing to prevent forgery

An electronic still camera comprises an image sensor which allows each of its horizontal lines to be individually specified so that a video signal contained in each specified horizontal line can be read, a storage circuit for storing the video signal read from the image sensor, a selecting circuit for selecting a high-speed continuous shooting mode, and a controlling circuit for executing, when the high-speed continuous shooting mode is selected by the selecting circuit, control to effect a high-speed reading for reading the video signal from the image sensor by thinning out the horizontal lines of the image sensor, and to cause the storage circuit to store video signals for a plurality of pictures obtained by the high-speed reading.

In a conventional system to which a plurality of devices are connected by a serial bus, the throughput of the network decreases due to transfer of a large amount of data. In this invention, a controller connected to the devices via a 1394 serial bus calculates a band width necessary for data transfer in a specific one of the devices, ensures the first channel corresponding to the band width, and transfers data to the specific device using the first channel. This enables preferential data transfer to the specific device to avoid a decrease in throughput.

An original is allowed to pass on an exposing glass along a conveying path, thereby exposing and scanning a front surface of the original and reading an image by a CCD. A back surface of the original is subsequently fed to the exposing glass along a conveying path and is allowed to pass on the exposing glass, thereby exposing and scanning the back surface of the original. The image data read by the CCD is stored into an image buffer. The order of address columns to read out the image data on the front surface and the order of address columns to read out the image data of the back surface are made opposite. Thus, a copying apparatus which can efficiently expose and scan both of the front and back surfaces of a both-side original is provided.

Copying apparatus capable of exposing and scanning both-side original

An image processing apparatus includes a processing unit for processing an image signal into which an original document, after being exposed to light, is photoelectrically converted, a compression module for compressing image information processed through the processing unit, a memory for storing image data compressed by the compression module, a control unit for setting a diversity of image processing modes, and a predicting module for predicting an image compression rate used by the compression module. The predicting module predicts the image compression rate of an image after being processed according to the image processing mode set by the control unit.

An original document reading apparatus includes a first control portion for performing a first control wherein documents are transported at a first document interval in the event that a detected occupying capacity is less than a detected unused capacity. The first control portion also performs a second control wherein documents are transported at a second document interval which is greater than the first document interval in the event that the detected occupying capacity exceeds the detected unused capacity. A second control portion continuously activates an exposure portion under the first control, and intermittently activates the exposure portion under the second control.
