IMAGE CAPTURE DEVICE AND IMAGE PROCESSING METHOD

摘要

Provided is an image capture device which is capable of reducing errors in the growth index of a plant, even if affected by changes in light such as sunlight, and which is capable of preventing a user from making erroneous judgements. In a monitoring camera, an image sensor captures a colour image of a plant, i.e. an object, via a visible-light filter (an infrared cut-off filter). An image processing unit detects a green-component luminance value (G value) in the colour image of the plant, said colour image having been captured by the image sensor (22), and controls the light-exposure conditions of the image sensor such that the G value becomes equal to an ideal G value (the green-component luminance value obtained under specific conditions, such as capturing the image in the daytime during fair weather). A transmission unit outputs, to a monitor, the colour image captured while the light-exposure conditions are in the controlled state. The monitor displays the colour image on a screen.
