IMAGE FORMING APPARATUS THAT FORMS IMAGE ON SHEET USING TONE CORRECTION CONDITION CORRESPONDING TO PROCESS SPEED - A simplified explanation of the abstract
This abstract first appeared for US patent application 18326201 titled 'IMAGE FORMING APPARATUS THAT FORMS IMAGE ON SHEET USING TONE CORRECTION CONDITION CORRESPONDING TO PROCESS SPEED
Simplified Explanation
The patent application describes an image forming apparatus that can convert the density of an image formed on an image carrier at one process speed into a density at another process speed. This is achieved through the use of a storage unit and a control unit.
- The storage unit stores conversion information that allows for the conversion of image density from one process speed to another.
- The control unit forms multiple patch images of different densities on the image carrier for each process speed.
- The control unit determines the densities of the patch images based on the process speed and the conversion information.
- The control unit generates tone correction conditions that correspond to each process speed.
Potential applications of this technology:
- Printing industry: This image forming apparatus can be used in printers and copiers to ensure consistent image quality at different process speeds.
- Graphic design: Designers can use this technology to accurately preview how an image will appear at different printing speeds.
- Photography: Photographers can benefit from this technology when printing their images at various speeds, ensuring accurate reproduction of colors and tones.
Problems solved by this technology:
- Inconsistent image quality: Different process speeds can result in variations in image density. This technology solves this problem by providing a conversion method to maintain consistent density.
- Difficulty in predicting image appearance: Without this technology, it can be challenging to anticipate how an image will look when printed at different speeds. This invention provides a solution by generating tone correction conditions.
Benefits of this technology:
- Consistent image quality: By converting image density between process speeds, this technology ensures consistent and accurate image reproduction.
- Time and cost savings: With the ability to predict and adjust for image appearance at different speeds, users can avoid costly reprints and save time in the printing process.
- Enhanced creativity: Designers and photographers can have more control over the final appearance of their images, allowing for greater creative expression.
Original Abstract Submitted
An image forming apparatus includes a storage unit configured to store first conversion information for converting a density of an image formed on an image carrier at a process speed into a density at another process speed among a plurality of process speeds; and a control unit configured to form a plurality of first patch images of different densities on the image carrier, with respect to each of the plurality of process speeds, determine respective densities of the plurality of first patch images based on a process speed at the time of formation of each of the plurality of first patch images and the first conversion information, and generate pieces of the tone correction condition that respectively correspond to the plurality of process speeds.
