To provide an automatic traveling device capable of automatically traveling along a desired route without performing positioning. An automatic traveling deviceis a device that performs predetermined work on crops S which are detection targets arranged in its traveling direction. A cameraacquires image data by capturing an image of the crops S in the traveling direction of the automatic traveling device. The recognition unitdisposes a plurality of determination windows (such as determination windowsL andR) at positions determined in advance with respect to the image data, and recognizes the crops S in the plurality of determination windowsR and the like. The adjustment unitadjusts the traveling direction of the automatic traveling deviceon the basis of a result of recognition performed by the recognition unit

Automatic traveling device

To reduce pixel position deviations in a plurality of color component images projected by a projection unit, a projection apparatus obtains, concerning the plurality of color component images projected onto the projection surface, position information concerning a projection position of each of remaining color component images with reference to a projection position of one color component image, and performs image processing for at least one of the plurality of color component images based on the obtained position information.

Projection apparatus and control method thereof

A plurality of sub-frame images are generated from an input frame image. Lightness of one or more sub-frame image included in the plurality of sub-frame images is adjusted to generate a light image and a dark image. Color-non-uniformity correction processing is performed on the light image and the dark image to reduce color non-uniformity of a display device using a correction value in accordance with an adjustment degree of the lightness.

Each frame image is acquired as an input image. An image obtained by emphasizing high frequency components in the input image is generated as a high frequency component emphasized image, a composite image is generated by compositing the input image and an input image of a previous frame before the input image, and an image including low frequency components in the composite image is generated as a low frequency component image. Then, the high frequency component emphasized image and low frequency component image are alternately output as images of sub-frames of the input image.

Image processing apparatus, image processing method, and storage medium

A low frequency component image L[i] and high frequency component-emphasized image SH[i] are generated from an image A[i]. Lossy compression processing is performed for the low frequency component image L[i] to generate a compressed image C[i] and store it in a memory. A compressed image C[i&#x2212;1] is decoded to generate a decoded image L'[i&#x2212;1]. The compressed image C[i] is decoded to generate a decoded image L&#x2032;[i]. A difference image E[i] between the decoded image L&#x2032;[i] and the low frequency component image L[i] is generated. The low frequency component image L[i], decoded image L&#x2032;[i&#x2212;1], and difference image E[i] are composited at a predetermined ratio to generate a composite image SL[i]. The high frequency component-emphasized image SH[i] and composite image SL[i] are output as subframe images of the i-th frame.
