Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital cameras face issues with heat generation during long-term moving image recording, leading to temperature rises that can cause noise in image sensors, inconvenience users by suddenly stopping recording when temperatures exceed a threshold, and potentially deform camera components.
Innovation Solution
An imaging apparatus with a temperature sensor that measures the camera case temperature, allowing users to set recording modes that manage heat generation, and displays the remaining recording time based on the temperature, enabling users to anticipate and manage potential recording stops.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the imaging sensor operates continuously for long periods to enable long-term moving image recording, then the recording duration is extended, but heat generation increases causing temperature rise that leads to noise and potential recording stop
Solution Approach 1:
The system performs preliminary measurement of the imaging sensor's temperature before recording begins, and calculates in advance the time required for the sensor to reach the allowable temperature limit. This advance warning allows users to plan recording sessions accordingly, avoiding unexpected interruptions while maximizing recording duration.
2Reliability
If the recording operation is stopped when temperature exceeds the allowable limit to prevent noise and damage, then the temperature-related problems are avoided, but the user cannot record important scenes which causes inconvenience
Solution Approach 1:
Instead of suddenly stopping recording when the temperature limit is reached, the system provides advance warning by calculating and displaying the time until the temperature reaches the limit. This allows users to prepare for the situation in advance, such as planning to end recording before the temperature threshold is reached, thereby avoiding abrupt interruptions and maintaining user convenience.
3Manufacturing precision
If the imaging sensor operates at high power to maintain high image quality, then the image quality is improved, but heat generation increases causing faster temperature rise
Solution Approach 1:
The system continuously monitors the imaging sensor's temperature and provides real-time feedback to the user through advance warning displays. By showing the estimated time until the temperature reaches the allowable limit, the system enables users to make informed decisions about balancing image quality settings with temperature management, allowing them to adjust recording parameters proactively rather than reactively.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to grasp when moving image recording may be stopped due to temperature rises, allowing them to take preventive measures, such as switching recording modes, and extends recording time by providing advance warning of impending temperature-related stops.
Implementation Method 1
a temperature sensor configured to measure a temperature of a case of the imaging apparatus
Implementation Method 2
The imaging sensor generates heat when performing the various processing operations. In particular, when operation is performed continuously for a long period of time such as when a moving image recording process is performed, a rise in temperatures of the imaging sensor and an image processing engine becomes more significant due to heat generation.

AI summary
An imaging apparatus includes a setting unit and a display controller configured to control the display unit. A plurality of recording modes include a first recording mode which generates heat so that the temperature in the case reaches a predetermined temperature, and a second recording mode which generates heat so that the temperature in the case cannot reach the predetermined temperature. The display controller determines the remaining recording time based on the temperature of a case, and determines whether the set-up recording mode is the first recording mode, and determines, based on a result of the determination, whether to display a remaining recording time which is determined based on the temperature in the case, on the display unit.
