Abstract: A check sheet includes: a reagent container that contains a reagent that changes color by being brought into contact with a target element generated from skin; and a plurality of filters provided in different positions from each other at the opposite side to the side of the reagent container to be attached to the skin along the reagent container, and emitting light in wavelength regions different from each other. A check sheet includes: a reagent container that contains a reagent that changes color by being brought into contact with a target element generated from skin; and a filter provided at the opposite side to the side of the reagent container to be attached to the skin, and transmitting light in a part of a wavelength region detectable by a light detector detecting a color of the reagent.

Abstract: An operation for selecting a desired one of images can be simplified. Still image data sets are sequentially read from a recording medium according to order of file names and displayed on a TV. Upon display, the still image data sets are in a non-selection state. If an instruction is not input from a remote controller within a predetermined time since the display of one of the still image data sets, the still image data set being displayed is set to a selection state and the following still image data set having the file name that comes next is displayed. If an instruction is input from the remote controller for display of the following still image data set within the predetermined time, the still image data set being displayed is left in the non-selection state, and the following still image data set is displayed.
