Abstract: A printer is permitted to obtain printed matter of high picture quality from print data transferred in the state changed into 1 bit for the purpose of shortening data transfer time. A multi-value conversion unit (23) converts CMYK respective 1 bit binary data from an expansion unit (22) into multi-valued data. The multi-value conversion unit sets values that a remarked pixel should take, which corresponds to circumstances of surrounding pixels, in a table where two gradation data (0, 1) of the remarked pixel and two gradation data of pixels around the remarked pixel, e.g., upper and lower, left and right and oblique eight pixels are assigned to respective digits of binary number of eight figures are taken as parameter to make reference to this table to thereby convert two gradation data into multi-valued data.

Abstract: A “cell broadcast information accumulation section” which accumulates cell broadcast information received by a “cell broadcast receiver” by relating it to the reception date and time, and especially information of a category for which the distribution area is “only one cell” (regional information). According to the cell broadcast information (especially regional information) accumulated in the “cell broadcast information accumulation section”, the “location judgment section” judges the address of the area where the mobile terminal existed (that is, where the user was present) at the aforementioned reception date and time.

Abstract: An image signal processing apparatus includes a data table that is configured to associate values of pixel data that can be input for error diffusion with parameters used for error-diffusing the pixel data. The apparatus further includes a parameter reading unit that reads a parameter from the data table using a value of input pixel data to be error-diffused as a read address, the parameter being associated with the value of the input pixel data, and an error diffusion unit that error-diffuses the input pixel data using the read parameter.

Abstract: A characteristic curve is defined on a coordinate plane defined by a first axis indicating a perceptually uniform scale and a second axis indicating grayscale values of original data. The perceptually uniform scale is given by a normalized one of chromatic tristimulus values to the power of 1/3. A boundary value at a level of error diffusion is determined based on the characteristic curve and is stored in a storage device. The boundary value is read from the storage device for error diffusion processing, and error diffusion is performed on input image data using the read boundary value.

Abstract: In a liquid discharging method for discharging droplets from a plurality of droplet discharging portions of a liquid discharging head, an actual pattern is created to indicate the discharging states of the droplets from the liquid discharging portions, and information about a defective liquid discharging portion having discharging failure is obtained by checking the discharging states. According to the information, the defective liquid discharging portion is prohibited form discharging, and discharging of droplets from a liquid discharging portion near the defective liquid discharging portion is controlled to reduce the influence of discharging failure of the defective discharging portion, and to correct image information on a recording medium.

Abstract: A printer is permitted to obtain printed matter of high picture quality from print data transferred in the state changed into 1 bit for the purpose of shortening data transfer time. A multi-value conversion unit (23) converts CMYK respective 1 bit binary data from an expansion unit (22) into multi-valued data. The multi-value conversion unit sets values that a remarked pixel should take, which corresponds to circumstances of surrounding pixels, in a table where two gradation data (0, 1) of the remarked pixel and two gradation data of pixels around the remarked pixel, e.g., upper and lower, left and right and oblique eight pixels are assigned to respective digits of binary number of eight figures are taken as parameter to make reference to this table to thereby convert two gradation data into multi-valued data.

Abstract: An ejection control device includes a memory for storing a correspondence table between gray-scale data items and ejection pattern data items, each gray-scale data item determining the number of droplets to be ejected to a corresponding pixel so as to express a desired gray-scale level of the pixel, each ejection pattern data item determining the ejection timing of droplets; and a converter for converting each gray-scale data item of the corresponding pixel to the corresponding ejection pattern data item by referring to the table. In the table, the setting of the ejecting position can be freely adjusted. In particular, an ejection pattern having ejection data bits discretely distributed for one pixel range can be easily achieved. Moreover, compliance with system changes can be achieved simply by rewriting the table.

Abstract: In a liquid-ejecting method for ejecting liquid contained in a liquid chamber from a nozzle as a liquid droplet group, the ejection amount of each liquid droplet of the continuously ejected liquid-droplet group can be stabilized corresponding to a wide frequency band of a pulse signal.

Abstract: The present invention relates to a method of registering a location in a mobile communication system in which the call signal traffic can be further reduced without increasing the location registration signal traffic. When a base station ID defined by notification information changes, or when a predetermined period of time has passed, the base station ID is stored in the history of the mobile device. From the latest history of the mobile device, one or a plurality of base stations near which the mobile device has a possibility of passing by next are statistically predicted. The predicted base stations are then stored as a personal location registration area. Based on the history, the registered personal location registration area is extracted so as to perform a location registration operation. Accordingly, the location registration operation can be performed with the optimum personal location registration area for the movement pattern of each mobile device.

Abstract: A liquid discharge apparatus includes a liquid discharge head (120) having ink discharge nozzles (203) for discharging droplets of inks, and a head controller (162) for controlling the liquid discharge head to discharge droplet from liquid discharge units onto the surface of recording paper (P), wherein the liquid discharge head includes the plural liquid discharge heads in a direction perpendicular to movement direction of recording paper where the recording paper is relatively moved with respect to the liquid discharge head. The head controller serves to allow discharge timings of droplets in movement direction of the recording paper to be different every one pixel in movement direction of the recording paper to eliminate stripes apt to take place when a portion or the entirety of image is printed by one scanning operation to obtain image having less defect.

Abstract: The invention makes it possible to quickly confirm the safety of people in an area stricken by a disaster such as an earthquake while protecting people's privacy, even in a situation where communication calls cannot be established due to network congestion.
