摘要:
Predetermined additional information is superposed as a dot pattern on image information read by an image scanner, and the image information superposed with the additional information is modulated. The modulated information is demodulated and recorded on a recording medium to perform a series of operations, i.e., to simultaneously satisfy both pattern addition and modulation/demodulation.

A plurality of apparatuses can execute an encrypting process on an image signal are connected. The encrypting processes which are executed in those apparatuses are independently performed, so that the connection of an improper apparatus is made impossible and, in this state, a more advanced signal process can be performed, thereby giving no disadvantage to the user. For this purpose, there is disclosed an image processing apparatus comprising a first encrypting circuit for encrypting the image data and supplying to a first apparatus and a second encrypting circuit for encrypting image data and supplying to a second apparatus different from the first apparatus, wherein the first and second encrypting means execute independently the encryption.

A device for controlling the copying of an original includes a discriminator for discriminating a specific original in accordance with the degree of significance of the specific original, when discriminating a plurality of specific originals in forming one image. According to another embodiment, the device includes an inhibitor for inhibiting the copying of a specific original, when a memory or peripheral circuit having the discrimination criteria of the specific original is removed or exchanged, or it is out of order, and making a discrimination of the specific original by the same characteristic data of the specific original, even if the image is input from different input equipment, wherein the correct discrimination is effected based on the color tint distribution of the specific original.

In an image reading apparatus for reading an original image using a light source containing a plurality of color components, a control pulse for dimming the light source is generated by pulse-width modulation symmetrically with respect to a reference timing (for example, the central position in one storage time or the storage start timing) in one predetermined storage time of a line sensor.

To control a light emitted from a fluorescent lamp having phosphors with different afterglow properties for different colors, a center of a lighting control signal for controlling the lighting of the fluorescent lamp is controlled to constantly align with the center of a Hsync period so that despite the variation of the lighting time of the fluorescent lamp, a barycenter of the quantity of light from the fluorescent lamp in the Hsync period almost aligns with the center of the Hsync period to reduce the offset of the barycenter.
摘要:
An image forming system has a plurality of image forming devices connected via a network. The system includes an image processor which processes an input image signal to produce a processed image signal. Respective additional information is superimposed on the processed image signal in a form that is not conspicuous to the human eye in preparation for transfer of the processed image signal to each of the plurality of image forming devices, with the respective additional information being different for each of the plurality of image forming devices. The processed image signal with the respective additional information superimposed thereon is transferred via the network to the respective ones of the image forming devices via the network.
