An information processing device for a web conference system includes a speaker to output sound, a microphone to receive sound, and a processor. The processor controls the speaker to output a predetermined tone and acquires first sound data from the microphone while the speaker outputting the predetermined tone. The processor sends the first sound data to another information processing device via a network or the like. Second sound data is then received from the other information processing device. The second sound data corresponds to the first sound data as output by the other information processing device. The processor then compares the first sound data and the received second sound data, outputs a notification indicating a result of the comparison between the first and second sound data.

A deformation detecting device comprises a vibration module configured to vibrate a first point of a measuring plane of a measured object in a non-contact manner; a transmission time measurement module configured to measure transmission time of vibration from the first point to a second point of the measuring plane in a non-contact manner; an inclination measurement module configured to measure an inclination of the measuring plane to a reference surface in a non-contact manner; and a determination module configured to determine presence/absence of deformation in the measured object by comparing the transmission time with reference transmission time serving as transmission time of vibration from the first point to the second point in a case in which there is no inclination of the measuring plane and corrects the reference transmission time in response to the inclination of the measuring plane.

A distance measurement apparatus comprises an acquisition section which counts time between a first timing when an output of a photodiode built in a semiconductor laser exceeds a first threshold value because a laser element of the semiconductor laser starts to output laser light and a second timing when the output of the photodiode exceeds a second threshold value higher than the first threshold value because the laser light is reflected by a measurement object and returns to the laser element, and acquires the counted time as flight time of the laser light from a moment when the laser light is output to a moment when the laser light is reflected by the measurement object and returns to calculate a distance from the laser element to the measurement object or displacement of the distance.

A beam light scanning apparatus capable of reducing influences of variations in characteristics of circuits disposed in a signal path extending until a laser driver and speeding up image data transfer for scan and exposure. Data of each line is distributed by an image data I/F into data trains of two channels, i.e., an odd-numbered pixel train and an even-numbered pixel train. The data in the two-channel trains are written by writing units into a plurality of memories in parallel for each of the trains in response to a line sync signal. During the same processing cycle as that for the writing, the data are read out of the memories in parallel by reading units. The data of two channels are combined by a multiplexer into a data train in the original order of pixels in each line, and a driving signal based on the combined data is generated by a PWM. A laser is driven by the driving signal.

In the light amount correction in the main scanning direction, sets of correction values of black and cyan for which the reflection frequency of optical elements are equal to an even number of times are made common to each other (a correction value set&#x2014;KC), and sets of correction values of magenta and yellow for which the reflection frequency of optical elements are equal to an odd number of times are made common to each other (a correction value set&#x2014;MY), whereby sets of correction values stored in a correction value storage portion in a correction value setting portion are reduced to two sets. Furthermore, in connection with this, the number of DA converters is reduced to two DA converters of a DA converter&#x2014;K, C and a DA converter&#x2014;M, Y.

Image forming apparatus

An image forming apparatus includes a light generator (e.g., laser) generating a scanning light beam and a driver driving the light generator depending on a drive signal to be provided. In this apparatus, data formed of image information at each pixel of each line along a main scan direction of an image to be targeted are distributed into a plurality of strings (i.e., channels) of data (e.g., two strings). Concerning each pixel provided by data in each string, information indicative of both a start and an end of modulation (e.g., PWM) is then produced. By using the start and end information, a modulator performs modulation depending on the data of each pixel in each string, providing a modulated signal. The modulated signals from the plural strings are mutually synthesized at synchronizes timings, being provided as the drive signal and given to the driver.
