Solution Overview
Problem
Existing image forming methods using silver halide photographic photosensitive materials struggle to provide a time difference in image appearance recognition timings across different regions of an observation image, limiting the ability to control the visibility of images formed by chemical reactions.
Innovation Solution
An image forming method that involves creating specific drawing conditions for different regions of an observation image, allowing for intentional variation in image appearance recognition timings by adjusting the chemical reaction progression and colorant release in mono-sheet-type silver halide photographic photosensitive materials, enabling distinct visibility times for each region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the image is formed by chemical reaction of precursor in mono-sheet-type silver halide photographic photosensitive material, then the image can be completed quickly, but the image appearance recognition timing is the same for all regions, preventing temporal variation effects
Solution Approach 1:
The patent applies local quality by creating different drawing conditions for different regions of the observation image. Specifically, it sets a first drawing condition for a first image region and a second drawing condition for a second image region, where these conditions result in different image appearance recognition timings. This allows the image to have spatially varying temporal characteristics, enabling effects such as sequential appearance of different image parts.
2Ease of manufacture
If the same drawing conditions are applied to all regions, then the image formation process is simple, but the temporal variation effect is lost
Solution Approach 1:
The patent segments the observation image into multiple regions (first image region and second image region) and applies different drawing conditions to each segment. This segmentation approach allows independent control of image appearance recognition timing for each region while maintaining the overall simplicity of the image formation process. The system divides the complex task of temporal variation control into manageable regional segments.
Solution Approach 2:
The patent implements local quality by assigning distinct drawing conditions to different regions. The first drawing condition and second drawing condition are specifically designed to produce different image appearance recognition timings for their respective regions, enabling temporal variation effects while keeping the manufacturing process straightforward through localized parameter adjustment.
3Adaptability or versatility
If different drawing conditions are applied to different regions, then the image appearance recognition timing varies by region, but the process complexity increases
Solution Approach 1:
The patent achieves temporal variation control by changing drawing parameters (such as exposure conditions, development parameters, or chemical reaction conditions) for different regions. Instead of using complex control systems, it achieves the desired temporal variation effects through parameter changes in the drawing conditions, making the process manageable despite the increased complexity of handling multiple conditions.

AI summary
There are provided an image forming method, an image forming apparatus, and an image forming program capable of giving a temporal change to an observation image by intentionally providing a time difference between image appearance recognition timings for a plurality of regions of the observation image. There is provided an image forming method of forming an observation image by exposing a photographic photosensitive material using an input image and performing development processing. The observation image includes an image A of a first image region in which the image appearance recognition timing after a start of development processing is relatively earlier and an image B of a second image region in which the image appearance recognition timing after a start of development processing is relatively later. First, two original images are acquired, and a first original image and a second original image respectively corresponding to the first image region and the second image region are determined. For the first original image and the second original image, a first drawing condition that satisfies a condition of the image appearance recognition timing of the first image region and a second drawing condition that satisfies a condition of the image appearance recognition timing of the second image region are created. The input image which is to be used for forming the observation image is generated based on the first original image, the first drawing condition, the second original image, and the second drawing condition.
