Imaging apparatus

Abstract

The invention provides an imaging apparatus which can suppress error operation during automatic correction of unintelligibility during image shooting through simple processing, and accurately provide notification corresponding to the unintelligibility correction to a user. The imaging device (1) includes an imaging unit (10) for imaging light from a target area on an imaging element (14), an image processing unit (21) for processing a signal output from the imaging element (14) and outputting image information, and a storage unit (22) for storing a reference value of a parameter indicating a sharpness of the captured image. The image processing unit (21) acquires the measured value of the parameter according to the signal inputted by the imaging element (14), stores the measured value obtained at a specific time point as a reference value in the storage unit (22), and conduct sharp processing for the captured image according to the difference between the obtained measured value and the reference value stored in the storage unit (22). In addition, the image processing unit (21) outputs information indicating that the sharp processing has been performed to the output unit (26).

Description

technical field [0001] The present invention relates to an imaging device for photographing a target area, in particular, an imaging device suitable for photographing scenery whose clarity may be reduced due to rain or fog. Background technique [0002] Camera devices are known which take pictures of streets or intersections with surveillance cameras. Such an imaging device uses captured images for identification of traffic accidents, for example. In the identification, it is possible to check the conditions of vehicles and pedestrians, the lighting conditions of traffic lights, and the like. In other words, it is possible to confirm whether the traffic lights are lit in red, blue, or yellow at the time of an accident. [0003] However, in places such as streets and intersections, the contrast of the subject may be lowered due to rain or fog. For example, if the intersection is covered with fog, there is a concern that the conditions of vehicles and pedestrians, the light...

Problems solved by technology

However, in this way, it may cause the viewer watching the shooting image to be unable to grasp the actual occurrence of rain or fog and the degree of rain or fog on the shooting site.

As a result, there is concern that the handling of the shooting scene cannot be accurately obtained
