Image Scanner Transmission Scanning Standard Driver
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image processing apparatuses controlled by standard drivers cannot perform transmission scanning, limiting their ability to read transmissive originals such as negative films, even if they are capable of reflection scanning.
Innovation Solution
The image processing apparatus executes scan processing in transmission mode using a scan program that generates display images from read images, allowing it to read transmissive originals by mimicking the processing of reflective originals, even when controlled by a standard driver that does not support transmission scanning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a standard driver is used to control the image processing apparatus, then compatibility with OS upgrading and security problems are improved, but the ability to perform transmission scanning and utilize extended functions deteriorates
Solution Approach 1:
The patent introduces a translation layer that acts as an intermediary between the standard driver and the image processing apparatus. This translation layer receives standard driver commands intended for reflective scanning and translates them into transmission scanning commands, enabling the apparatus to perform transmission scanning even when controlled by a standard driver that lacks native support for this function.
2Adaptability or versatility
If a vendor driver is used to control the image processing apparatus, then extended functions such as transmission scanning are improved, but security problems and adaptability to OS upgrading deteriorate
Solution Approach 1:
The patent enables the image processing apparatus to handle multiple driver types universally. By implementing a translation layer that can interpret standard driver commands and convert them into apparatus-specific commands, the system achieves multi-functionality, supporting both standard drivers (for security and compatibility) and vendor drivers (for extended functions) without requiring separate control paths.
3Device complexity
If the image processing apparatus is designed to support only reflection scanning under standard driver control, then device complexity is reduced, but the ability to read transmissive originals deteriorates
Solution Approach 1:
The image processing apparatus performs self-service by automatically detecting whether a transmissive original is placed on the platen and autonomously switching between reflective and transmission scanning modes. The apparatus includes a sensor that detects the presence of a transmissive original, and based on this detection, the control unit automatically configures the lighting and scanning parameters without requiring user intervention or complex external control.

AI summary
A control method for an apparatus for controlling a reading apparatus that performs reading in a transmission mode includes a read controlling step, a generating step and a processing step. In a read controlling step, the reading apparatus is controlled to read at least one film in the transmission mode based on a reading instruction from operating system standard software. In a generating step, a display image is generated, in which at least one frame image is arranged, based on a read image obtained by the reading in the read controlling step. In a processing step, a processing for displaying the display image generated in the generating step by using the operating system standard software, is executed.
