Description

Camera system and camera fill light method

This creation is related to a camera field, in particular, a camera system and a camera fill method that calculate the best placement position of the fill light through a test and provide a prompt message to the photographer.

In recent years, optical digital cameras have become popular with network technology. Many photographers like to upload captured images to the Internet for sharing. The images after shooting may be affected by the brightness of the environment at the time. The main features in the resulting image (such as portraits, dishes, or artwork) are too dark, making the overall look unattractive.

In order to solve the above problem of insufficient brightness, it can be improved by modifying the image. The computer is used to modify the brightness and chroma of the image with the repair software to solve the improvement. However, the threshold of this method is higher, and the modified image will be improved. There is a kind of unreality, such as the inconsistency of the difference in chroma brightness of the adjacent areas in the image, or the inconsistency of the reflective position (such as eye light).

Another method is to use the fill light to directly fill the brightness when shooting. However, the distance and angle between the fill light and the subject will affect the effect after the fill light. For example, the fill light may not be obvious when it is too far or The whole picture is too bright (the subject in the image is too white), too close to cause a certain area to be too bright, so that the difference in brightness of the overall picture is too large to look uncoordinated, so the placement of the fill light directly affects the shooting. As a result, the placement position usually depends on the experience of the photographer, non-professional The photographer has no way to quickly find the best placement position of the fill light and the suitable fill light parameters for the current shooting needs. It can only be slowly improved through repeated attempts and accumulated experience.

In order to improve the above problems, the main object of the present invention is to provide an imaging system and an image filling method for generating a result of a difference between a current position of a fill light and an optimum placement position through a test.

Another main object of the present invention is to provide an imaging system and an image-filling method for providing an optimal placement position of a fill light according to a drop result.

To achieve the above objective, the present invention provides a camera system that establishes a wireless communication connection with at least one fill light. The camera system includes: a camera having a lens, a shutter, and an image sensing component for capturing The image in the perspective of the lens generates an original image information; an image processor electrically connects the camera to analyze the original image information and generates an image subject result; and a fill light controller electrically connects the camera And the image processor and a wireless communication module to control the opening and closing time of the shutter, and send a test flash to the fill light through the wireless communication module; the camera is during the test flash A first light source image information is generated, and the fill light controller calculates the optimal placement position of the fill light by comparing the difference between the original image information and the first light source image information and referring to the image theme result.

The invention further provides an image filling method, comprising the steps of: a. a camera system and a fill light establish a wireless communication connection; b. one of the camera systems captures an original image information; c. The camera system transmits a first test light signal to cause the fill light to perform a first test flash, and the camera system captures, by the camera, the first light source image information during the first test flash period of the fill light; d. The subject and the fill light computing unit in the camera system have a difference in brightness or chroma between the original image information and the first light source image information; e. the theme and the fill light computing unit are the same according to the different image information Determining the current position of the fill light on the difference in brightness or chroma on the block; and f. the theme and the fill light computing unit determine an optimal placement position of the fill light based on the original image information, and calculate Out of the result of the difference with the current position of the fill light.

When the fill light 2 is moved, the fill light 2 will prompt the photographer according to the difference between the current position and the optimal placement position, and continuously communicate with the fill controller 13 of the camera system 1. For example, when the fill light 2 is far away from the optimal placement position, the flash of the drop warning light is relatively slow, and the flashing speed gradually becomes faster as it approaches, and the warning light falls when the optimal placement position is reached. The light color changes and is constantly bright, and the change of the flash light allows the photographer to know the fill light 2 to reach the optimal placement position.

In the above case, the photographer can also be prompted by the falling warning sound. When the fill light 2 is far away from the optimal placement position, the time difference between the two sirens of the drop warning sound is longer, when approaching the two The time difference between the second beeps is gradually shortened. When the optimal placement position is reached, the drop warning tone is changed to play music or a sound different from the tweet. The change of the sound allows the photographer to know the fill light 2 to reach the optimal pendulum. Put the position.

The above-mentioned drop warning light and drop warning sound can be used simultaneously or alternatively. For example, when the light is too bright, the warning light is not obvious, or when the need to maintain a quiet environment, the warning sound is not suitable, through the warning light and warning. The two ways of sound can be used either at the same time or at the same time, so that the best placement position can be found quickly and conveniently.

In addition, the fill light controller 13 continues to update the position of the fill light 2 before and after the light source 21 of the fill light 2 for a period of time, and continuously updates the current position of the fill light 2 and the optimal placement. The result of the drop in position is the best placement through continuous comparison.
