摘要:
When a recording mode of a printer is changed to a resolution expansion mode when an internal temperature of a recording head falls or by an external indication, the number of divided blocks is changed so that the overlap of on time zones of block sub-division signals is prevented in order to assure that heaters of the recording head are energized for a sufficient time period. Thus, the heater energization time period for each block is extended without extending the total recording time.

An information transmitting mechanism is described for transmitting information of an ink tank of an ink jet recording apparatus to a controller thereof. The recording apparatus performs recording by scanning a carriage on which a recording head and the ink tank are mounted; the ink tank is removably mounted to said recording head. The information transmitting mechanism includes the ink tank and the recording head; in particular, the ink tank has an information mark. The recording head is connected to the ink tank and has a signal terminal making a signal connection with the ink tank and with the controller of the apparatus. The content of the information mark is transmitted to the controller through the signal terminal. The information relating to the ink tank is transmitted to the controller through the head terminal and through the carriage terminal. The information relating to the recording head is transmitted to the controller through the carriage terminal.

The purpose is to provide a high quality halftone recording with a reduced grainy feeling without lowering the true resolving power. Provided is an apparatus for making a halftone recording by employing three or more types of color materials, each of which has at least one grade of concentration, wherein each type of the color materials having the lowest concentration provides, when recording on a recording medium having a first lightness, a recorded region having its own lightness, and wherein a difference between the first lightness and the lightness of the recorded region is not more than 35, the lightness being measured according to the definition of CIE 1976 psychological measurement lightness using a standard illuminating light D65 as a light source.

An image processing apparatus includes an obtaining unit, a determination unit, a setting unit, and a processing unit to perform an image edge intensifying processing. The obtaining unit obtains image data by reading a document. The determination unit determines an image edge direction. The setting unit sets an edge intensifying processing intensity based on the image data and a processing intensity determined corresponding to a difference between resolution in a main scanning direction and resolution in a sub-scanning direction. The processing unit performs the image edge intensifying processing according to the set intensity. In response to the resolution of the image data being higher in the sub-scanning direction than in the main scanning direction, the setting unit sets a higher intensity of the edge intensifying processing in response to the edge direction being along the sub-scanning direction than in response to the edge direction being along the main scanning direction.
摘要:
The present invention provides a system for analyzing an expression profile in which a large number of expression profile data obtained by a next-generation high-speed sequencer, a similar experimental technique, or the like is analyzed at high speed by a general-purpose computer, gene expression patterns are visualized, thereby easily analyzing to which gene a novel gene is similar in function. A system for analyzing an expression profile which analyzes gene expression profile data includes a storage unit which stores the number of counts of mRNAs expressed from a subject gene to be evaluated as expression data under each of a plurality of gene expression conditions for each subject gene name, a correspondence analysis unit which reads the expression data from the storage unit for each subject gene, and carries out correspondence analysis on the basis of the number of counts under each expression condition in expression data, a coordinate conversion unit which converts n-dimensional (n: natural number) scores obtained by the correspondence analysis to coordinate values for m-dimensionally (m: natural number, m≦n) arranging each subject gene, and an image processing unit which carries out plotting along the corresponding coordinate values for each gene to display the result on an image display unit.

An adaptor which mediates between an image supply device and a printer causes the printer to print by selecting either of the first operation mode in which image data from the image supply device is received by wireless communication and before the completion of receiving the image data, a print job is issued to the printer by wired communication, and the second operation mode in which image data from the image supply device is received by wireless communication and after the completion of receiving the image data, a print job is issued to the printer by wired communication.
摘要:
When a digital camera and printer are directly connected via a communication interface, and a recording process in the printer is interrupted while transmitting image data from the camera to the printer and recording the image data, the camera designates the restart of the recording process and it is determined whether the printer is of a type capable of restarting the recording process. In a case where the printer is determined to be the type capable of restarting the recording process and a DPOF (digital print order format) file is being printed, the DPOF file is resent to designate printing from a page next to the printed page. In a mode in which image data are sequentially transmitted to the printer and printed, a print process of image data subsequent to the printed image data is designated.
