A handheld implement with a replaceable work tool includes a handle body which is equipped with a locking device for detachably mounting the work tool. The locking device includes a movable member, at least one retaining member and a first spring. The first spring abuts against the retaining member so that the retaining member is inserted into a locking hole of the work tool while remaining in an extended state. The retaining member includes a first mating body including at least one second mating body. The second mating body includes a mating portion, and the movable member performs translational movement so that the mating portion and the first mating body cooperate with each other to drive the retaining member to retreat and then withdraw from the locking hole of the work tool.

The present application provides an image enhancement method and system, the method includes acquiring an input brightness value, and computing a log average value of the input brightness value; processing the input image based on a Retinex image enhancement algorithm to obtain a first brightness gain value; computing a brightness gain control factor according to the log average value of the input brightness value; computing a second brightness gain value according to the brightness gain control factor and the first brightness gain value; and obtaining an output image by enhancing the input image according to the second brightness gain value. The present application uses a Retinex image enhancement algorithm to enhance the input image, and by using the brightness gain control factor, when the image has low brightness, the first brightness gain value is compressed, and when the image has high brightness, the first brightness gain value is compressed slightly.
