Abstract: Provided are a transmission device, a transmission method, and a program capable of performing rate control suitable for an image quality priority image. A basic parameter value decision section (28a) decides, for a frame image that is not an image quality priority image, values of parameters used for encoding an encoding unit that is a part or whole of the frame image, by applying the difference between a control amount and a target value to a predetermined control rule. An image quality priority parameter value decision section (28b) decides, for the frame image that is the image quality priority image, values by which the data size of the generated image data becomes larger than those decided by applying the difference between the control amount and the target value to the predetermined control rule as the values of the parameters used for the encoding unit of the frame image.

Abstract: A transmission apparatus, a transmission method, and a program that can reduce the number of times that useless transmission of image data is performed due to a failure in reception of image data indicating a reference destination. A transmission failure likelihood data management section checks the likelihood of a failure in transmission of first image data. Second image is an image rendered in a frame buffer for the first time after a timing when a predetermined time has elapsed since the transmission of the first image data. An encoding processing section controls whether or not to generate second image data requiring no reference destination, depending on the likelihood of the failure in the transmission of the first image data at a timing of encoding the second image.

Abstract: An information processing apparatus including a memory and a memory controller writing data to the memory in response to a write for writing the data to the memory, in which the memory executes error correction processing for each data of a predetermined data length, and the memory controller executes, in place of the memory, read modify write processing in a case where a data length of the data related to the write instruction is smaller than the predetermined data length.

Abstract: The present disclosure provides a head-mounted display that includes an image generation device generating a display image to be viewed through an eyepiece disposed in front of a display panel, the image generation device including a source image reception control section that receives a source image, a distorted image generation section that generates data on pixels in a display image obtained by giving the source image a distortion corresponding to the eyepiece, a partially distorted image storage section that stores the data on the pixels in an order of data generation, and an image display control section that, whenever data on a predetermined number of pixels smaller than a total number of pixels in the display image is stored in the partially distorted image storage section, outputs the stored data to the display panel; the display panel that sequentially displays data outputted from the image generation device; and a content processing device that generates the source image and transmits the generated source image to the head-mounted display.

Abstract: Disclosed herein is an image processing method executed by an image processing apparatus. The image processing method includes designating a distribution of pixels whose charge is to be added and read out from among pixels an image sensor has, and acquiring data of a captured image in which an area of a region that is a unit from which charge is to be read out differs depending upon a position by the designation.
