Abstract: A picture image processing apparatus includes a circuit device having a horizontal reduction circuit that reduces input picture image data in the horizontal direction at a specified horizontal reduction rate and a vertical reduction circuit that reduces input picture image data in the vertical direction at a specified vertical reduction rate. According to the picture image processing apparatus, the picture image processing apparatus capable of improving the degree of freedom in picture image data reduction can be provided.

Abstract: Provided is a technique capable of flexibly incorporating a function according to needs, taking into consideration a user's selection of a function to be enhanced. According to the technique, provided is a function enhancement device 3 detachably interposed between an imaging device 1 configured to image a subject and acquire image data, and an interface device 2 configured to perform data communication with an external device so as to enhance a function of the imaging device 1. The function of the imaging device 1 to be enhanced is selectable from at least one of an image processing function of processing the image data, an operation environment retaining function of retaining an operation environment of the imaging device 1, a transmission method changing function of changing a transmission method of image data, and a subject recognition function of recognizing a subject from image data.
