    Abstract: A placement detection system includes: a placement table; an imaging device that images an object placed on the placement table to generate an input image; and a control device. The control device generates a first binarized image for the input image based on a first threshold value and determines whether the object is placed in a predetermined placement orientation. The control device changes a threshold value for a target pixel to a second threshold value higher than the first threshold value when the object is determined to be placed in the predetermined placement orientation, the target pixel being sandwiched between pixels having pixel levels lower than or equal to the first threshold value and has a higher pixel level than the first threshold value in a first region, generates a second binarized image for the target pixel based on the second threshold value, and detects a shape of the object.

    Abstract: A placement detection system includes: a placement table; an imaging device that images an object placed on the placement table through the placement table to generate an input image; and a control device that receives the input image. The control device identifies a higher-level pixel having a pixel level higher than or equal to a predetermined pixel level in the input image, sets a threshold value of the higher-level pixel, and sets a threshold value of a target pixel other than the higher-level pixel to a lower value than the threshold value of the higher-level pixel in accordance with a distance between the higher-level pixel and the target pixel. The control device binarizes a pixel level of the target pixel in accordance with the threshold value of the target pixel to produce a binarized image and detects a shape of the object by using the binarized image.

    Abstract: An extraction unit determines whether, in a display area of a display unit in which content data obtained from an acquisition unit are displayed, there is a character area in which an area occupied by a character has a proportion greater than a predetermined value. Based on color information of the character in an area which is determined to be the character area by the extraction unit, a setting unit sets a target color temperature when the content data is displayed. A converter changes an original color temperature of the content data to the target color temperature, based on the target color temperature set by the setting unit.
