A distance measurement image pickup apparatus has two measurement periods. In a first distance measurement period, short pulsed light (1T) is irradiated, and exposure is performed in a plurality of exposure periods (A, B, and C) in which exposure timings are shifted. In each exposure period, an exposure gate is opened a plurality of times to perform repetitive exposure, and a first non-exposure period is provided from when a last exposure gate is closed until subsequent pulsed light is irradiated. In a second distance measurement period, long pulsed light (4T) is irradiated, and exposure is performed in a plurality of exposure periods (A, B, and C) in which exposure timings are shifted. In each exposure period, exposure is performed by opening the exposure gate only once, and a second non-exposure period is provided from when a last exposure gate is closed until subsequent pulsed light is irradiated.

Distance measurement image pickup apparatus

A distance measurement apparatusincludes: a TOF camerahaving a light-emitting unit, a light-receiving unit, and a distance-calculating unitto measure a distance to the subject on the basis of light transmission time; and an image processing unitthat creates a distance image of the subject from distance data measured by the TOF camera. The image processing unitdetermines whether or not there is a detection target in the created distance image. If there is no detection target in the distance image, the light emission intensity control unitdecreases the emitted light intensity from the light source of the light-emitting unit, and the operation mode is switched to a power saving mode in which the pixel addition control unitincreases an addition ratio of a neighboring pixel signal of the light-receiving unit

An object position detection apparatusincludes a distance image generation unitwhich generates a two-dimensional distance image by measuring a distance to a subject including an object on the basis of a light transmission time, an object image generation unitwhich generates an object image in which the object is extracted from the distance image of the subject, and an installation angle detection unitwhich detects an installation angle of the distance image generation unit. The object image generation unitincludes a differentiatorwhich performs a process of removing a background other than the object from the distance image of the subject and a threshold value d for removing the background in the differentiatoris set in response to the installation angle of the distance image generation unitdetected by the installation angle detection unit

Object position detection apparatus

An imaging device () is provided with: an imager () that includes an imaging element with multiple pixels arranged two-dimensionally, and that outputs an image signal in accordance with setting of either a pixel addition readout method or a cutout readout method; a signal processor () that processes the image signal from the imager (); an operator () that inputs operation information; a lightness detector () that detects a subject lightness; and a controller (). The controller () includes a zoom setter () that sets a zoom magnification for a subject based on a zoom signal that is input by the operator (), and a readout-method switching controller () that switches between the pixel addition readout method and the cutout readout method according to the zoom magnification set by the zoom setter () and the lightness detected by the lightness detector ().

Device, method, and recording medium for setting a readout method based on a zoom setting and identified threshold value

The present invention evaluates the quality of an image shot by a terminal device in a state closer to that seen with the eye. A computer evaluates the quality of an image obtained by shooting a photographic subject including a periodic pattern that fluctuates periodically in one direction. A Fourier transform unit accomplishes a two-dimensional Fourier transform on the image to obtain two-dimensional spatial frequency spectrum components. An analysis unit analyzes the resolution of the image on the basis of spectrum components of spatial frequencies included in the periodic pattern, among the two-dimensional spatial frequency spectrum components obtained by the Fourier transform unit, and analyzes the deterioration of the image on the basis of spectrum components other than these.

Image deterioration when image data containing scanning lines of the previous and next fields mixed together by video editing is displayed is prevented. An inter-field scanning line interpolating unit superimposes scanning line data of the previous and next fields of interlacing image data in a video stream input from a tuner or a memory card to perform inter-field scanning line interpolation, and generates progressive image data corresponding to that video stream. An IP-conversion selection signal indicating a determination result whether or not the reliability of the video stream meets a predetermined level is input into a back-end from a CPU. A selector refers to the IP-conversion selection signal, and when the CPU determines that the reliability of the video stream is lower than the predetermined level, image data having undergone interpolation by the inter-field scanning line interpolating unit is selected as an image to be displayed.
