Projector Image Area Emphasis via Local Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current projector technologies do not effectively highlight specific areas within projected images on a screen, limiting the ability to draw attention to important details during presentations.
Innovation Solution
A projector apparatus with an input section for indicating specific areas and an image processor that applies image processing to emphasize these areas, either by connecting to external devices or using a photographing section and area specifying function to determine areas based on indicated position information, allowing for highlighting through various image processing techniques.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If image processing is applied to emphasize specific areas, then viewer attention is improved, but device complexity increases
Solution Approach 1:
The patent applies different image processing treatments to different areas of the projected image. Specifically, it processes the specific area indicated by the user with emphasis enhancement while leaving other areas unchanged or applying different processing, thereby creating local quality differences that draw viewer attention without requiring complex global processing systems
Solution Approach 2:
The patent divides the projected image into at least two segments: a specific area that receives emphasis processing and other areas that receive different or no processing. This segmentation allows the system to apply complexity only where needed (in the specific area) rather than requiring complex processing of the entire image
2Ease of operation
If area indication input is added to the projector, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The patent enables users to self-select and indicate specific areas of interest directly on the projected image using simple input methods. The system provides the capability for users to perform the area selection themselves without requiring complex pre-programming or external device control, thereby improving ease of operation while keeping the added complexity minimal and user-controllable

AI summary
To provide a projector apparatus capable of giving attention stably and clearly to a specific area within an image projected and displayed on a screen, and to provide a display output method and display output program of the apparatus. For that purpose, the projector apparatus for projecting and displaying an image on a screen comprises an input section which accepts an indication of a specific area within the projected and displayed image; and an image processor that subjects a specific area and/or an other area within the image to image processing for emphasizing the specific area, the other area being an area other than the specific area in the image.
