Solution Overview
Problem
Digital cameras experience increased power consumption and computation processing load when simultaneously executing face detection, motion detection, and wireless communication functions, leading to reduced shot capacity and live view image display rates during remote shooting.
Innovation Solution
An image capturing apparatus with a communication unit, image capturing unit, setting unit, and control unit that specifies objects with reduced processing when receiving instructions from an external apparatus, and a communication apparatus with a reception unit, display unit, and transmission unit that designates and transmits object information to the image capturing apparatus, allowing for efficient remote shooting without performing motion detection or person recognition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If face detection, motion detection, and person recognition functions are executed simultaneously with wireless communication during remote shooting, then shooting functionality is maintained, but power consumption increases and computation processing load increases
Solution Approach 1:
The patent extracts and removes the motion detection function and person recognition function from the simultaneous execution set during remote shooting. The control unit determines that only face detection is necessary, eliminating the harmful computational load of motion detection and person recognition while maintaining essential shooting functionality through wireless communication.
Solution Approach 2:
The patent applies partial action by executing only the necessary face detection function rather than all three functions (face detection, motion detection, and person recognition). This partial execution of detection functions reduces computation processing load and power consumption while still providing sufficient object specification capability for remote shooting.
2Adaptability or versatility
If face detection, motion detection, and person recognition functions are executed simultaneously with wireless communication during remote shooting, then shooting functionality is maintained, but computation processing load increases
Solution Approach 1:
The control unit extracts and removes the motion detection function and person recognition function from simultaneous execution during remote shooting. This extraction reduces the computational complexity by eliminating redundant processing while maintaining essential shooting functionality through the remaining face detection capability and wireless communication.
Solution Approach 2:
The patent applies partial action by executing only face detection rather than all three detection and recognition functions. This partial execution reduces computation processing load while providing sufficient object specification capability for remote shooting operations.
3Measurement precision
If all detection and recognition functions are executed during remote shooting, then object specification accuracy is improved, but the number of possible shots decreases
Solution Approach 1:
The control unit extracts and removes the motion detection function and person recognition function during remote shooting operations. This extraction maintains sufficient object specification accuracy through face detection alone while reducing power consumption, thereby preserving the battery life and number of possible shots.
Solution Approach 2:
The patent applies partial action by executing only face detection rather than all three functions. This partial execution provides sufficient object specification accuracy for remote shooting while conserving energy, thus maintaining a higher number of possible shots.
4Measurement precision
If all detection and recognition functions are executed during remote shooting, then object specification accuracy is improved, but live view image display rate decreases
Solution Approach 1:
The control unit extracts and removes the motion detection function and person recognition function during remote shooting. This extraction reduces computation processing load, allowing live view images to be processed and displayed at a higher rate while maintaining sufficient object specification accuracy through face detection.
Solution Approach 2:
The patent applies partial action by executing only face detection rather than all three functions. This partial execution reduces computational burden, improving the live view image display rate while providing adequate object specification accuracy for remote shooting operations.

AI summary
An image capturing apparatus comprises a communication unit configured to communicate with an external apparatus, an image capturing unit configured to generate image data by capturing an object, a setting unit configured to set a shooting condition, a specifying unit configured to specify an object in image data captured by the image capturing unit, wherein the object specified by the specifying unit is used to set the shooting condition by the setting unit, and a control unit configured to control the specifying unit so as to specify the object with less processing when shooting upon receiving an instruction from the external apparatus connected via the communication unit based on the object specified by the specifying unit as compared to a case in which shooting is performed by directly operating the image capturing apparatus.
