Image processing apparatus and image processing method

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.

An image capturing apparatus comprises an image sensor, and a controller that controls the image sensor to shoot images for display at a first cycle and controls to shoot a still image in response to the image shooting instruction. In a case where continuous shooting of still images is instructed during shooting the images for display at the first cycle, the controller changes a cycle at which the images for display are shot to a second cycle which corresponds to an integer multiple of speed of the continuous shooting while e continuous shooting is performed, and controls the image sensor to shoot the still images at the speed of the continuous shooting and shoot the images for display at the second cycle.

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.

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.
