  • Publication number: 20240171832
    Abstract: An information collection apparatus communicates with an external apparatus, acquires first information relating to a use environment of the apparatus and second information corresponding to a target for the inference processing, executes inference processing by applying the second information and third information set on a basis of the first information to the learned model, and sets the third information on a basis of a range of a first threshold of the first information. When the first information is within a range of a second threshold, the third information is selected on a basis of the range of the first threshold of the first information. When the first information is not within the range of the second threshold, the third information is acquired from the external apparatus via the communication unit so that the first information is within the range of the second threshold.

  • Publication number: 20230116274
    Abstract: An image processing apparatus having appropriate capability while reducing power consumption is disclosed. The image processing apparatus comprises a first tracking unit and a second tracking unit having a higher processing accuracy and a greater operational load than the first tracking unit. The image processing apparatus computes an evaluation value pertaining to difficulty of tracking for a subject region as a tracking target determined in a target frame to which tracking processing is to be applied. The image processing apparatus, based on the evaluation value, activates both the first tracking unit and the second tracking unit, or deactivates at least one of the first tracking unit and the second tracking unit for a subsequent frame to the target frame.

  • Publication number: 20220309706
    Abstract: An image processing apparatus includes an analysis unit for analyzing an image, an extraction unit for extracting a reference image corresponding to a specific object, and a first correlation calculation unit and a second correlation calculation unit for presuming an area having a high correlation in an input image by using the reference image. The first correlation calculation unit executes presumption based on components including a direct current (DC) component, and the second correlation calculation unit executes presumption based on an alternate current (AC) component, from which the DC component is eliminated. Based on at least any one of a detection result of the specific object, a feature amount of the specific object, and an analysis result of an imaging scene, acquired by the analysis unit, the first correlation calculation unit and the second correlation calculation unit are switched when the area is presumed.

  • Patent number: 11356611
    Abstract: An image capture apparatus comprising an image sensor is disclosed. When an instruction to shoot a still image has been detected when executing a live view display, the image capture apparatus shoots the still image preferentially, while repeatedly displaying a same image during a period in which the live view display cannot be updated. The image capture apparatus reduces a luminance and/or changes a tone of the image that is repeatedly displayed.

  • Patent number: 11356603
    Abstract: An image capturing apparatus comprising an image sensor and a control circuit is disclosed. The control circuit changes, if a second drive period that is a drive period of the image sensor for still image shooting overlaps with a first drive period that is a drive period of the image sensor for moving image shooting, a start timing of the second drive period. When performing still image shooting while performing moving image shooting and moving image display: if the still image shooting is single image shooting or a first shot of continuous shooting, the control circuit does not change the start timing of the second drive period. If the still image shooting is a second shot onward of continuous shooting, the control circuit changes the start timing of the second drive period with giving priority to the moving image display.

  • Patent number: 11050928
    Abstract: There is provided an image capturing control apparatus. A first control unit performs control to repeatedly obtain an evaluation image using an image sensor. The evaluation image is used to obtain an evaluation value for controlling at least one of image capturing and development. An obtaining unit obtains the evaluation value on the basis of the evaluation image. A second control unit performs control to temporarily stop the obtainment of the evaluation image and use the image sensor to obtain, during a stopped period, a still image for recording. A generating unit generates an estimated evaluation image corresponding to the stopped period on the basis of two or more evaluation images obtained outside the stopped period. For the stopped period, the obtaining unit obtains the evaluation value on the basis of the estimated evaluation image.
