Benefits of technology

The patent describes an imaging device and electronic terminal that can communicate with each other. The imaging device captures live-view images and sends them to the electronic terminal without interruption. The electronic terminal manipulates the device and sends an imaging request to the device, which then sends the live-view image without interruption. The electronic terminal displays the live-view image on its screen. The technical effect of this technology is to ensure smooth and quick imaging operation when the device is manipulated and imaging is performed.

Problems solved by technology

Therefore, there is a concern that the user will not get to see the live-view image after the imaging operation, and there is a possibility that imaging manipulations cannot be performed in succession and an opportunity to capture an image will be lost.

embodiment 1

1. Embodiment 1

[0021]1-1. Configuration

[0022]FIG. 1 shows a configuration of a camera system 1 according to embodiment 1. The camera system 1 is configured from a camera body 100 (one example of an imaging device), and an exchangeable lens 200 that is detachable from the camera body 100.

[0023]In FIG. 1, electrical configurations including detailed power supply lines of the camera body 100 and the exchangeable lens 200 are omitted.

[0024]1-1-1. Configuration of Camera Body

[0025]The camera body 100 is, e.g., a mirrorless imaging device that is not provided with an optical finder. The camera body 100 is provided with a body controller 140, an imaging element 110, a liquid-crystal monitor 120, a view-finder (VF) 121, a manipulation unit 130, a body-side mount 150, a power supply 160, a card slot 170, a shutter 180, and a communication unit 191.

[0026]The body controller 140 (one example of a first controller) is configured from, for example: a central processing unit (CPU), a micro proces...

embodiment 2

2. Embodiment 2

[0085]A camera body 100 and an electronic terminal 300 according to embodiment 2 are described with reference to FIGS. 7 and 8.

[0086]The configurations of the camera body 100 and the electronic terminal 300 are the same as those in embodiment 1 shown in FIGS. 1-3, and therefore descriptions of these configurations are omitted. As pertains to matters not particularly described in embodiment 2, embodiment 1 and modification examples thereof are applied, provided there are no particular contradictions.

[0087]In embodiment 1, the thumbnail image is generated from the image frame of the live-view image and is displayed. However, there are cases where the live-view image is transmitted in a state in which, e.g., a part of the image has color applied through peaking (a function to apply color to high-contrast portions and display the image with the colored portions); therefore, the thumbnail image could also be displayed with color applied thereto, the thumbnail image being d...

Abstract

In a camera body capable of connecting to an electronic terminal, an imaging element captures an image of a subject and generates a live-view image. A transmission unit transmits the live-view image to the electronic terminal. A reception unit 191b receives, from the electronic terminal, an imaging request for the camera body. A body controller controls the imaging element, the transmission unit, and the reception unit. The body controller executes imaging performed by the imaging element and acquires a first image frame, which is a captured image, in response to the imaging request. The transmission unit transmits the live-view image to the electronic terminal after the imaging request without any interruption caused by transmission of the first image frame in response the imaging request.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of foreign priority to Japanese Patent Application No. 2019-129304, filed on Jul. 11, 2019. The entire disclosure of Japanese Patent Application No. 2019-129304 is hereby incorporated herein by reference.BACKGROUNDTechnical Field[0002]The present disclosure relates to an imaging device, an electronic terminal capable of connecting to the imaging device, and an imaging system provided with the imaging device and the electronic terminal.Background Art[0003]Japanese Laid-open Patent Publication No. 2015-95799 discloses a system to transmit image data from a camera to an electronic terminal. In this system, the camera generates a low-resolution live-view image in sequence from an output signal of an imaging element, and then transmits the low-resolution live-view image through UDP to the electronic terminal at a prescribed transmission rate. When a user makes an input operation to the electronic terminal for...
