A method of evaluating the quality of an image includes a step of determining at least a parameter concerning a zone or a parameter concerning a distribution pattern of sampling points within the zone. This step is performed based on the image. For each zone, Fourier analysis is performed using the optical characteristic values of the respective sampling points within the zone, and the image quality of each zone is obtained. The quality of the image is then determined based on the image quality of each zone within the image. A suitable zone and distribution pattern of sampling points are employed in evaluating the quality of an image.

A cooling system for a vacuum processing apparatus is provided with an internal heat conduction path for transfer of heat entering the subject body through the vacuum processing apparatus, a heat radiation path for radiation of the heat to an outside of the vacuum processing apparatus and a heat conduction path for regulation of quantity of heat transfer between the internal heat conduction path and the heat radiation path. Preferably, a heat pipe is applied to the internal heat conduction path.

An inkjet recording apparatus includes a recording head having a nozzle row aligned with a plurality of nozzles and a carrying mechanism capable of carrying a record medium by a multiple of an arbitrary natural number of a unit carry amount in a direction in parallel with the nozzle row. The record medium is carried by any of quasi logical carry amounts including a natural number larger than a logical carry amount determined based on a recording resolution and a number of nozzles and represented as a multiple of the unit carry amount and a natural number smaller than the logical carry amount. The record medium is recorded at each time of carrying the record medium. A carry amount of the record medium is determined such that a difference between the logical carry amount and an actual carry amount of the record medium does not exceed a predetermined value.

In an image-forming method, a device reads line data L for one line and determines whether the resolution of the line data L in the main scanning direction is greater than or equal to a threshold th. If the resolution is greater than or equal to the threshold th, then a multiple line process is performed on the line data L to divide this data into two sets of partial line data L1 and L2. The partial line data 'L1 and L2 are used to form two lines at locations shifted from each other in the sub-scanning direction. However, if the resolution of the line data L is smaller than the threshold th, then a single line process is performed to divide the line data L into two segments Q1 and Q2. The segments Q1 and Q2 of the line data L are used to form a single line at the same location in the sub-scanning direction by printing the segment Q1 in the first main scanning operation and by printing the segment Q2 in the second main scanning operation.

An apparatus for forming thin films forms a plurality of thin films in a single chamber by sequential formation of at least a first and a second thin film on a substrate by an antenna type plasma CVD method. This apparatus is provided with a residual material removal apparatus, which removes from the chamber residual materials resulting from the step for forming the first film and which affect the properties of the second film. A method and an apparatus for forming films and a solar cell removes residual material (including material gas) resulting in the step for forming the first film which have an effect on the properties of the second film. Since a plurality of films are deposited inside a single chamber, it is unnecessary to provide a plurality of chambers, thus enabling the apparatus and solar cell to be more compact and of reduced cost.

An operator selects printer characteristics in S201. When a correct calibration file exists (S202:YES), then in S203 calibration data is retrieved from the correct file. When no correct calibration file exists (S202:NO), then in S204 calibration data is retrieved from the reserved file. The reserved file can be a calibration file that is retained when a calibration file is updated or can be a calibration file that is originally provided within the printing system when the printing system is shipped from the factory. When calibration data is retrieved from a correct file or a reserved file, then in S205 original tone levels, included in image data from some upper rank program, are converted into input tone levels, to be applied to the printer, which executes printing accordingly.
摘要:
In order to prepare tone characteristic data or calibration data based on measurements of tone levels of four colors by nine tones, the lowest tone level in measured only once using a single patch that is common to all the four colors. As a result, the entire operation time can be reduced by the time that is required to measure three more patches. If there is a considerable gap between the actually-measured output level and a predicted output level (S114:NO), then an error message is displayed (S115). Then, the measurements are performed once again. Therefore, wasteful operations will not be continued with the tone characteristic data in its mistaken form. Instead displaying the error message, the error-occurring output value can be replaced with a value that is determined by interpolating between non-error-occurring output values around the error-occurring output value.

A color conversion function is corrected in accordance with the input color data (Xin, Yin, Zin) of the original image. The original image is therefore converted into colors which are different from colors of the original image but which are appreciated by the user. One or more specific color is previously determined. The appropriate color value memory 40 stores appropriate output values (Xbesti, Ybesti, Zbesti) for the specific colors. The color value discrimination portion 20 judges whether or not the input color data (Xin, Yin, Zin) is the specific color. When the input color data (Xin, Yin, Zin) is judged as the specific color, the corrected characteristic value calculation portion 24 calculates a correction characteristic value (dXi, dYi, dZi) based on the input color data (Xin, Yin, Zin) and the appropriate calor value. The color-conversion characteristic value correction portion 26 corrects conversion data (A, B, C) stored in the color-conversion characteristic value memory 42 based on the corrected characteristic values (dXi, dYi, dZi). The color conversion portion 28 converts the input color data (Xin, Yin, Zin) based on the corrected conversion data (a, b, c) produced and stored in the corrected color-conversion characteristic value memory 50, thereby outputting desired corrected color data (Xout, Yout, Zout).
摘要:
When the profile data outputted from the external CPU 4 is not consistent with the contents of the memories 40 and 46 (no in S3), data in the first conversion characteristic memory 40 is rewritten with the profile data in S4. In S5, several color signals are generated. Then, in S6, the first color conversion process is attained to convert the several color signals into first intermediate signals. The second color conversion process is attained in S7 to convert the first intermediate signals into the second intermediate signals based on a stored color conversion characteristic. Thus, the third color conversion characteristic is produced in S8. In S11, with using the thus produced third color conversion characteristic, the third color conversion process is attained to convert the actually-inputted color data into control signals.
