An image processing apparatus that handles RAW images efficiently performs editing for reproducing RAW images.

The apparatus compresses each of RAW images and reduced RAW images which are reduced from the RAW images, and records each in a recording medium. When editing, the image processing apparatus communicates with an external apparatus and transmits the reduced RAW images stored in the recording medium to the external apparatus, and causes the external apparatus to perform editing processing of the reduced images. Further, the image processing apparatus uses editing information representing the content of editing processing from the external apparatus to execute editing of the RAW image corresponding to the reduced RAW image on which the editing processing has been performed, by referencing the editing information.

Among other things, embodiments of the present disclosure improve the functionality of electronic messaging and imaging software and systems by automating the client-side transcoding of video data based on content. For example, an appropriate transcoding configuration can be selected for video data having complex motion or textures. Accordingly, video quality can be improve when complex motions or textures are present.

A recording method includes: acquiring a video stream containing a picture that is independently decodable; recording the acquired video stream on a recording medium; storing, in memory, a value indicating a data size of a picture defined in a third GOP management table obtained by merging a first GOP management table with a second GOP management table; and converting the stored value into either a first value defined in the first GOP management table or a second value defined in the second GOP management table, and recording the converted value on the recording medium.

A video transmitting circuit and a signal delay compensation method thereof are provided. The video transmitting circuit transmits a specific signal through a first transmission path and a second transmission path to a video receiver during a calibration mode. In the calibration mode, a return detection circuit of the video transmitting circuit detects whether or not a first return signal transmitted through the first transmission path and a second return signal transmitted through the second transmission path have been received by the video transmitting circuit. The video transmitting circuit sets delay circuits serially connected in the first or second transmission path according to a detection result of the return detection circuit, such that the first return signal transmitted through the first transmission path and the second return signal transmitted through the second transmission path can synchronously arrive at the video receiver.

An imaging device includes an imager; a first-type encoder; a connector unit; an information acquiring unit for acquiring information on an encoder operation mode from a second-type encoder connected to the connector unit; and a selecting unit for selecting an encoder for a record purpose and an encoder for a distribution purpose, wherein the information on the encoder operation mode contains a low-delay mode and an image quality priority mode in which an image quality is given higher priority but an encoding delay is longer than those in the low-delay mode, and the selecting unit is configured to: select, when the information on the encoder operation mode indicates the image quality priority mode, the second-type encoder for the record purpose; and select, when the information on the encoder operation mode indicates the low-delay mode, the first-type encoder for the record purpose and the second-type encoder for the distribution purpose.

A pulse-density-modulation display and image capture system comprises a display comprising a plurality of pixels. Each pixel comprises a light emitter that controllably emits light at a constant current for a variable amount of time and a control circuit connected to the light emitter to control the light emitter to emit light in response to an input signal specifying the desired luminance of the light emitter. The control circuit converts the input signal to a non-contiguous pulse-density-modulation signal and controls the light emitter to emit light in response to the non-contiguous pulse-density-modulation signal with a temporally variable constant-current control signal. Each pixel emits light responsive to a display timing signal. The pulse-density-modulation display and image capture system also comprises a sampling camera that records the pixels and is responsive to a camera timing signal different from the display timing signal.
