Abstract
An image forming apparatus includes an acquisition unit configured to acquire image data, a generation unit configured to generate a histogram based on a signal value of each pixel in the image data acquired by the acquisition unit, a derivation unit configured to derive the number of pixels matching a first condition in the histogram generated by the generation unit, and a selection unit configured to select, according to the number of pixels derived by the derivation unit, one of a fixing processing adjustment mode for increasing a degree of gloss of a print product by adjusting fixing processing and a transparent toner mode for increasing a degree of gloss of a print product by using a transparent toner.

An image forming apparatus comprising:
- an acquisition unit configured to acquire image data;
- a generation unit configured to generate a histogram based on a signal value of each pixel in the image data acquired by the acquisition unit;
- a derivation unit configured to derive the number of pixels matching a specific condition in the histogram generated by the generation unit;
- a comparison unit configured to compare the number of pixels derived by the derivation unit with a first threshold value and a second threshold value that is greater than the first threshold value;
- and
- a selection unit configured to select a fixing processing adjustment mode for increasing a degree of gloss of a print product by adjusting fixing processing if the number of pixels derived by the derivation unit is smaller than the first threshold value and select a transparent toner mode for increasing a degree of gloss of a print product by using a transparent toner if the number of pixels derived by the derivation unit is greater than the second threshold value.
An image forming method comprising:
- acquiring image data;
- generating a histogram based on a signal value of each pixel in the acquired image data;
- deriving the number of pixels matching a specific condition in the generated histogram;
- comparing the derived number of pixels with a first threshold value and a second threshold value that is greater than the first threshold value;
- and
- selecting a fixing processing adjustment mode for increasing a degree of gloss of a print product by adjusting fixing processing if the derived number of pixels is smaller than the first threshold value and selecting a transparent toner mode for increasing a degree of gloss of a print product by using a transparent toner if the derived number of pixels is greater than the second threshold value.
A non-transitory computer-readable storage medium storing instructions which, when executed by an image forming apparatus, cause the image forming apparatus to perform a method, the method comprising:
- acquiring image data;
- generating a histogram based on a signal value of each pixel in the acquired image data;
- deriving the number of pixels matching a specific condition in the generated histogram;
- comparing the derived number of pixels with a first threshold value and a second threshold value that is greater than the first threshold value;
- and
- selecting a fixing processing adjustment mode for increasing a degree of gloss of a print product by adjusting a speed of executing fixing processing if the derived number of pixels is smaller than the first threshold value and selecting a transparent toner mode for increasing a degree of gloss of a print product by using a transparent toner if the derived number of pixels is greater than the second threshold value.
