[0006] Therefore, conventionally, the noise data that can be removed is limited to the case where the number of pixels is quite small and is separated from the print data to be printed.
As a result, with the conventional technology, the noise data concentrated in one part cannot be removed, and extra work is generated in the printing process.

no. 1 Embodiment approach
[0020] Hereinafter, an example of embodiment of the present invention will be described with reference to the drawings.
[0021] figure 1 A schematic configuration diagram showing the image processing device 100 according to the embodiment of the present invention is applied.
[0022] The image processing device 100 is, for example, a multifunction peripheral, a copier, or the like. As shown in the figure, the image processing device 100 has an image sensor 110 , an A / D conversion device 120 , a controller 130 and a print engine 140 .
[0023] The image sensor 110 outputs read signals (analog data representing luminance values of RGB colors) such as a document to the A / D conversion device 120 . Specifically, the image sensor 110 receives light reflected from a document or the like, and reads out charges accumulated according to the received light amount as a voltage, and outputs the voltage to the A / D conversion device 120 .
[0024] The A / D converter 120 converts (quanti...
no. 2 Embodiment approach
[0065] Hereinafter, an example of an embodiment different from the first embodiment described above will be described with reference to the drawings.
[0066] The image processing device 100 of this embodiment has the same hardware configuration and functional configuration as those of the above-mentioned first embodiment.
[0067] In this embodiment, the difference from the above-mentioned first embodiment is the method of making the cumulative histogram (the cumulative number of printed pixels Y x calculation method).
[0068] Figure 7 It is a flowchart for explaining the noise removal processing in this embodiment.
[0069] Similar to the first embodiment, the noise processing unit 203 starts this flow when the processing by the filter processing unit 202 ends, for example, with respect to the image data read by the image reading unit 201 .
[0070]When this flow is started, the noise processing unit 203 performs initial settings (step S201). Specifically, the noise pr...

Abstract
The invention provide an image processing apparatus, an image processing method, and a program, capable of removing noise data from the image data to be printed with better precision than that of the related art. The image processing apparatus comprises: a reading unit that reads image data; a counting unit that counts a number of pixels having a luminance equal to or smaller than a predeterminedluminance value at each position in a main scanning direction for the image data of a predetermined number of bands read by the reading unit; a cumulative value calculation unit that accumulates the number of pixels counted by the counting unit at each position of the main scanning direction; a cumulative value storing unit that stores the cumulative value accumulated by the cumulative value calculation unit; and a print range determination unit that determines a print start position based on a position where the cumulative value exceeds a predetermined threshold value, wherein the cumulativevalue calculation unit sets a value obtained by subtracting a predetermined value from the cumulative value, as the cumulative value, in the case where the number of pixels having a luminance equal to or smaller than a predetermined luminance value is not counted by the counting unit.
Description
technical field [0001] The present invention relates to an image processing device, an image processing method, and a program. Background technique [0002] Conventional inkjet multifunction printers are of a type capable of removing noise in areas outside the printing range by determining (changing) the printing range (for example, Patent Document 1). This also saves extra work for printing noise data outside the print range, and speeds up the print process. [0003] In such a conventional inkjet multifunction peripheral, a cumulative histogram of the number of printing pixels is created in units of bands for image data read from a document. Then, using the histogram of three bands combined with the cumulative histogram of the upper and lower bands, the position from one end of the band until the cumulative value of the number of printed pixels reaches a specific threshold is checked, and the print range is determined (changed) based on the position borders. [0004] The...
