12 (d) and (v) are output by the adder 78.
Is the same signal as shown in Fig. 12 (d) (v)
The signal is subtracted only from the black edge.   In other words, this means that the black edge portion is
The signal for determining the toner amount is strong, that is, the black toner amount is increased.
To reduce the amount of Y, M, C toner for the same part.
This means that the black part is expressed more black.   Signal 581 obtained by binarizing achromatic signal 580 by binarizing circuit 80b

As described above, the selector 79 uses the black toner mark.
At the time of printing (when 577 = "1"), S input = "1", A input,
That is, 579 (FIG. 12 (d) (iii)) is output and the black
The azalea is emphasized. When printing Y, M, C toner (577 = “0”
Time) is signal 581 = "1", so if achromatic,
In particular, B input is selected to reduce the amount of Y, M, C toner,
12 (d) and (v) are output.
No. 581 = 0, therefore ▲ ▼ = 1, ie, select
12 is set to 1 and the A input is selected.
(D) The signal of (iii) is output to the adder 78,
This is a well-known edge emphasis.   The LUTA73a has the edge signal as shown in FIG.
When the value is less than ± n, the LUT becomes zero and when the value is less than ± m
There are two types of LUTs that can be set to zero.

The density level of the original is set by the CPU 22 via the bus 508.
When the value is larger than the value
The output becomes "1", and is zeroed at A 'and B' in FIG. 12 (a).
The LUT to be ramped is also below a certain concentration, ie
When the output of the comparator 81 is “0”, A and B
Select the LUT to be pumped, and
The noise removal effect has been changed.   In addition, the output 583 of the AND gate 82 is around the edge of the black character.
This is a further improvement to the

The signal 586 input to the port 584 is LUTC
(FIG. 12 (c)) A binarizing circuit for a signal having the characteristic shown in FIG.
It is binarized at 80a, that is, the edge signal
It is "1" when the absolute value is equal to or greater than a predetermined value, and is "0" when the absolute value is less than the predetermined value.
Therefore, 587 = "1", 581 = "1", and 588 = "L".
Is achromatic and the edge signal is large, that is, the black signal
At the edge of the printer, and only when printing Y, M, and C toners.

It is distinguished by the part of the papier-mache. For example, on the computer 33 side
RGB image data is added to the image file name attached to the SCAN command.
If the extension “.R” is added to the
The CPU 4360 of the storage device 3 responds to the input from the input device by R
Input control as GB-based luminance image, and in the image storage device,
Register as RGB type image data.   FIGS. 60 and 61 show the structure of RGB type image data.   In the image storage device, register as shown in FIG.
Blocks of memory A to D (4060A to D)
Is configured as shown in FIG. 60 and the memory A (4060A)
For example, R image (4060A-R), G image (4060A-G), B image
Combination of each basic blot of image (4060A-B)
You. The image composition of the image is horizontal width
(Width) and vertical length height (height) in pixels
(Number of dots).   Specifically, it is an RGB color image, with one R, G, B
Each cell has a depth of 8 bits (1 byte)
It has a three-frame structure of R, G, and B.   Therefore, 256 gradations (0 to 255) are obtained for one pixel on the R surface.
256 × 256 × 256 ≒ 16.7 million color data on three sides of RGB
Data structure.   Note that 0 represents low luminance and 255 represents high luminance.   The data structure is in the R plane from the upper leftAre arranged in the order of data
