A size measurement device for measuring a size of an object from a captured image of the object includes: an imaging unit that captures an image of an object; a display unit that displays image data captured by the imaging unit; an input unit for inputting instructions of a user; a region setting unit that, when positions are designated with the input unit in the image data displayed on the display unit, sets surrounding regions including therein respective designated positions; and a feature point determination unit that determines, in the surrounding regions set by the region setting unit, feature points providing coordinates of the object to be measured.

Size measurement device and size measurement method

An image control device, which achieves energy saving effects without degradation of an image to be displayed, even if image data includes a fault, is configured to decode received image data into an image, generate display information based on the received image data, and output a decoded image and display information. The image control device receives image data, detects errors from the image data. For each error detected, the image control device specifies a fault image region containing an error from an entire image region of the image data, and inhibits use of the fault image region for generating display information that defines an image display condition according to which the display device performs the image display.

A specific color-adjusting stage adjusts data of an inputted color with respect to a specific color. A total color-adjusting stage adjusts the data of the inputted color with respect to a total color. The specific color-adjusting stage and the total color-adjusting stage are provided in parallel. A composing unit composes linearly an output of the specific color-adjusting stage and an output of the total color-adjusting stage. When a degree that the total color-adjusting stage adjusts the data of the inputted color increases, then a degree that the specific color-adjusting stage adjusts the data of the inputted color decreases, and vice versa.

Apparatus and method for adjusting inputted color concerning total and specific colors

There is provided a display control method capable of reducing unnecessary processing and unnecessary power consumption caused by is. The display control method uses an update judgment unit () for judging whether a display content has been updated, a characteristic amount extraction unit () for obtaining the characteristic amount of the display content, a control unit () for the characteristic amount extraction unit () to reference the obtained characteristic amount and decide a correction parameter, and a display content correction unit () for correcting the display content according to the correction parameter and outputting the corrected display content to a display device (). When the update judgment unit () has judged that the display content is not updated, the control unit () cuts off power supply to the characteristic amount extraction unit ().
